Notice: The Industry Canada label identifies certified equipment. This certification means that the equipment meets  
telecommunications network protective, operational and safety requirements as prescribed in the appropriate Terminal  
Equipment Technical Requirements document(s). The Department does not guarantee the equipment will operate to  
the user’s satisfaction.  
Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local  
telecommunications company. The equipment must also be installed using an acceptable method of connection. The  
customer should be aware that compliance with the above conditions may not prevent the degradation of service in  
some situations.  
Repairs to certified equipment should be coordinated by a representative designated by the supplier. Any repairs or  
alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications  
company cause to request the user to disconnect the equipment.  
Users should ensure for their own protection that the electrical ground connections of the power utility, telephone lines  
and internal metallic water pipe system, if present, are connected together. This precaution may be particularly  
important in rural areas.  
Caution: Users should not attempt to make such connections themselves, but should contact the appropriate electric  
inspection authority, or electrician, as appropriate.  
Notice: For equipment using loopstart lines, please note that the Ringer Equivalence Number (REN) assigned to each  
terminal device provides an indication of the maximum number of terminals allowed to be connected to a telephone  
interface. The termination on an interface may consist of any combination of devices subject only to the requirement  
that the sum of the Ringer Equivalence Numbers of all the devices does not exceed 5. The REN is located on the “FCC  
Rules Part 68” label located on the bracket of the module, or on the back of the unit.  
Canada CS-03 -- Règles et règlements  
Avis: L'étiquette d'Industrie Canada identifie le matériel homologué. Cette étiquette certifie que le matériel est  
conforme aux normes de protection, d'exploitation et de sécurité des réseaux de télécommunications, comme le  
prescrivent les documents concernant les exigences techniques relatives au matériel terminal. Le Ministère n'assure  
toutefois pas que le matériel fonctionnera à la satisfaction de l'utilisateur.  
Avant d'installer ce matériel, l'utilisateur doit s'assurer qu'il est permis de le raccorder aux installations de l'entreprise  
locale de télécommunication. Le matériel doit également être installé en suivant une méthode acceptée de  
raccordement. L'abonné ne doit pas oublier qu'il est possible que la conformité aux conditions énoncées ci-dessus  
n'empêche pas la dégradation du service dans certaines situations.  
Les réparations de matériel homologué doivent être coordonnées par un représentant désigné par le fournisseur.  
L'entreprise de télécommunications peut demander à l'utilisateur de débrancher un appareil à la suite de réparations ou  
de modifications effectuées par l'utilisateur ou à cause de mauvais fonctionnement.  
Pour sa propre protection, l'utilisateur doit s'assurer que tous les fils de mise à la terre de la source d'énergie électrique,  
des lignes téléphoniques et des canalisations d'eau métalliques, s'il y en a, sont raccordés ensemble. Cette précaution  
est particulièrement importante dans les régions rurales.

Avertissement: L'utilisateur ne doit pas tenter de faire ces raccordements lui-même; il doit avoir recours à un service  
d'inspection des installations électriques, ou à un électricien, selon le cas.  
Avis: Veuillez prendre note que pour tout appareillage supportant des lignes de type “loopstart,” l'indice d'équivalence  
de la sonnerie (IES) assigné à chaque dispositif terminal indique le nombre maximal de terminaux qui peuvent être  
raccordés à une interface. La terminaison d'une interface téléphonique peut consister en une combinaison de quelques  
dispositifs, à la seule condition que la somme d'indices d'équivalence de la sonnerie de tous les dispositifs n'excède pas

Chapter 1 Introduction  
Modems  
The Model 5399 Remote Access Concentrator Module can be configured  
with up to 62 internal DSP-based digital modems. The modems are  
dynamically downloaded with images to configure them to the  
appropriate protocol. The modems are located on plug-in modem cards  
installed on the module.  
System 5000 Common Management Bus  
The management section of the backplane is the common management  
bus (CMB), a high-speed, multimaster, shared-memory communication  
channel that connects all modules installed in the hub to one another and  
to the supervisory module. The modules installed in the hub use the CMB  
to acquire and distribute configuration and status information.  
The supervisory module is an intelligent interface between the Model  
5000 chassis and user-installed modules. The supervisory module  
provides the following services to other modules across the CMB:  
Maintains chassis component information and  
environmental status  
Stores the primary module configurations  
Restores the module configuration after the module power is  
cycled or the module is reset  
The supervisory module also supports configuration terminal support  
through the service port on the front panel of the chassis.  
System 5000 Backplane Ethernet Segment Banks  
divided into two banks of six segments each: segments 1 through 6 and  
segments 7 through 12. Each Model 5399 Remote Access Concentrator  
module installed in the chassis can be configured to access one bank of  
six segments, either segments 1 through 6 or segments 7 through 12. For  
more information, see “Setting the Backplane Ethernet Segment” on page  
2-3.

Chapter 1 Introduction  
Within a segment bank, the specific segment to which a Model 5399  
Remote Access Concentrator module is connected is determined by  
setting the segment selection DIP switch on the module. For more  
information, see “Setting the Backplane Ethernet Segment” on page 2-3.  
System 5000 Service Port Management  
The service port, located on the front panel of the chassis, provides a  
switched serial communication link between the service port and any  
for the Remote Access Concentrator installed in the hub.  
For more information, see “Connecting a Service Port Terminal” on page  
2-14, “Remote Access Concentrator Parameters” on page 2-18, and  
“Installing the Model 5399 Remote Access Concentrator” on page 2-3.  
Firmware and Software  
Firmware  
The Model 5399 Remote Access Concentrator’s ROM contains firmware  
for performing power-up self-tests and loading operational code. A  
non-volatile EEPROM stores the configuration parameters.  
The Remote Access Concentrator can boot from the boot image in its  
Flash memory or can boot an image received from a boot server on the  
network.  
ROM Monitor  
The ROM monitor is an interactive command interpreter that is used to  
define basic configuration parameter values. All of the information that  
the Model5399RemoteAccessConcentrator needstobootanoperational  
image is defined using the ROM monitor and its command set. ROM  
Monitor commands are issued from a terminal connected to the service  
porton the hubchassis.WhentheRemoteAccessConcentrator completes  
its self tests, the service port terminal displays the ROM monitor prompt.  
Using the ROM Monitor commands (see Chapter 3), you can:

Chapter 2 Installing the Model 5399 Remote Access Concentrator Module  
Installing the Model 5399 Remote Access Concentrator  
This section describes how to install the Model 5399 Remote Access  
Concentrator Module in a System 5000 Hub. Installing the Model 5399  
involves seating the backplane connectors to the Model 5000 Hub  
backplane and verifying the installation.  
Preparing for Hardware Installation  
This section explains how to prepare the Model 5399 for installation in  
the chassis.  
System 5000 equipment uses electronic components that are  
sensitive to static electricity. Static discharge from your clothing  
or other fixtures around you can damage these components. You  
should take all possible precautions to prevent static discharge  
damage when working with printed circuit boards. If possible,  
place all printed circuit boards on an antistatic mat until you are  
ready to install them. If you do not have an antistatic mat, wear  
a discharge leash to free yourself of static before touching any  
of the printed circuit boards, or free yourself of static by  
touching the metal of the chassis before handling a printed  
circuit card.  
Setting the Backplane Ethernet Segment  
Figure 2-1 shows the locations of the configuration jumper and DIP  
switch that you must set to select an Ethernet segment. They are:  
Ethernet segment bank selector (J5)  
Ethernet segment selection DIP switch (S1)

Ethernet Segment Bank Selector  
The Ethernet segment bank selector (see Figure 2-1), consisting of three  
rows of 20 pins (labeled J5, J21 and J22) and a jumper card, determines  
whether the module connects to Ethernet segments 1 through 6 or  
segments 7 through 12 at power up. When the jumper card is installed on  
the two rows of pins nearest the front of the module (using J21), the  
module has access to segments 1 through 6 (the factory default setting);  
when the jumper card is installed on the two rows of pins nearest the back  
of the module (using J22), the module has access to segments 7 through  
12.

Chapter 2 Installing the Model 5399 Remote Access Concentrator Module  
When the jumper card is installed between J5 and J21, the  
printed circuit card handle is nearest the front of the module. To  
install the jumper card between J5 and J22, remove the jumper  
card, rotate it 180 degrees (so that the printed circuit card handle  
is nearest the back of the module) and push it onto the pins (see  
Figure 2-1).  
The specific segment connection for the module is determined by the  
segment selection DIP switch (described in the next section).  
Network management software cannot override the bank  
selector setting. The setting (segments 1–6 or 7–12) can only be  
set while the module is outside the chassis.  
Segment Selection DIP Switch  
DIP switch S1 on the module (see Figure 2-1) is used to set the default  
segment selections. Segment selection DIP switch settings are listed in  
Table 2-2. Turning a DIP switch number ON selects a particular segment  
within the Ethernet segment bank. For example, turning on DIP switch  
number 1 selects either segment 1 or 7, depending on the position of the  
Ethernet segment bank selector jumper card.  
If no DIP switch numbers are turned on, the unit defaults to  
Segments 1 or 7 (depending on the position of the Ethernet  
segment bank selector jumper card).

Network management software can override this DIP switch  
setting, so an installed module may connect to a different  
segment (within the segment bank) than is indicated by the DIP  
switch setting.  
Installing the Module into the Hub  
To install and secure the module into the System 5000 Hub, follow these  
steps:  
1. Remove the blank filler panel from the chassis slot where  
you intend to install the module.  
2. Verify that the module jumpers are set correctly (see  
“Setting the Backplane Ethernet Segment” on page 2-3).  
3. Extend the inserter/extractor levers to their fully extended  
positions (see Figure 2-2).

Chapter 2 Installing the Model 5399 Remote Access Concentrator Module  
The Model Remote Access Concentrator performs a series of  
self-test diagnostics each time it is reset or powered up. These  
tests take about a minute to complete and cannot be deactivated.  
While these tests are running, the annunciator remains amber.  
The annunciator changes to green upon successful test  
completion. For information about possible error conditions, see  
Chapter 4.  
LED Indicators  
When the Remote Access Concentrator is operating correctly, the  
front-panel LEDs (see Figure 2-5) should appear as follows:  
Annunciator: The annunciator should be green. If the  
annunciator remains amber after completing the self-tests,  
refer to Chapter 4.  
Segment Connection LEDs: A steady green indicates which  
Ethernet LAN segment the module is using.  
Module Status LEDs:  
Init: Turns green when the module begins the  
initialization processafter a power-up or reset. Typically,  
this is the first LED that lights after power-up. The Init  
LED turns off after the initial diagnostics have  
successfully completed.  
Unit: Turns green after the module passes the power-up  
diagnostics. If the Unit LED turns amber, refer to  
Chapter 4.  
Net: Turns green after the module verifies that a valid  
Ethernet connection exists.

Concentrator is loading the operational image or  
dumping a RAM image if there is a failure.  
Verify that the hub front-panel LEDs are properly  
illuminated.  
If the LEDs do not light in the proper manner, or if the system operation  
displays indicate problems, see Chapter 4 for more details.  
Connecting a WAN Interface  
Be sure to properly configure the interface before connecting  
the cable. Some switch types will disable lines connected to an  
improperly configured device. See the Model 5399 Remote  
Access Concentrator Module Network Administrator’s Guide  
for details.  
A WAN Interface is used to connect the Remote Access Concentrator to  
channelized T1, channelized E1, or ISDN PRI lines. Follow the  
instructions in this section to connect the line to the WAN Interface port.

Chapter 2 Installing the Model 5399 Remote Access Concentrator Module  
Initial Setup and Using the ROM Monitor  
After installing the Remote Access Concentrator software on the file  
server host, collect the following information, which is required to  
determine the unit’s boot parameters:  
The location (directory path) of the download files on the  
host (tftp only).  
Whether the Remote Access Concentrator and host are on  
the same subnet or separated by one or more routers.  
Whether the host going to use tftp or erpcd (requires a  
UNIX or Windows NT® host) to serve the Remote Access  
Concentrator download code.  
The Remote Access Concentrator needs these parameters to perform an  
initial boot when loading the software. Enter these parameters into the  
EEPROM using the ROM monitor commands, which are accessed  
through a service portterminal. See Chapter 3 for more informationabout  
these commands.  
The Remote Access Concentrator supports the Bootstrap Protocol  
(BOOTP) and the Reverse Address Resolution Protocol (RARP) which  
can be used to obtain some of the information listed. If you have a host  
running BOOTP or RARP to serve the Remote Access Concentrator the  
information, the server will boot without user intervention. For more  
information about using these protocols, see Auto-initializing the IP  
Address Parameters” on page 2-23.  
The Remote Access Concentrator supports Windows NT® host  
tools. Remote Annex Server Tools for Windows NT® allows  
you to boot and configure the Remote Access Concentrator on a  
Windows NT® network. For more information, see the Remote  
Annex Server Tools for Windows NT® User Guide.

Chapter 2 Installing the Model 5399 Remote Access Concentrator Module  
Booting the Remote Access Concentrator  
You can boot the operational software by downloading the image from a  
host system or another Model 5399 Remote Access Concentrator, or by  
using the image contained in Flash memory (self-boot). However, before  
actually booting the unit, you must first initialize the IP address  
parameters either manually or by using the auto-initialize feature. The  
followingsectionsdescribesthe two methodsofinitializingthe IP address  
parameters, and the various boot methods.  
Auto-initializing the IP Address Parameters  
The Remote Access Concentrator is distributed without an IP address or  
preferred load host defined in ROM. When the device is booted, the  
Remote Access Concentrator attempts to auto-initialize itself using  
BOOTP (bootstrap protocol) and RARP (Reverse Address Resolution  
Protocol).  
This method of initializing the IP address parameters is  
generally done when booting from a host system (not when  
self-booting).  
The Remote Access Concentrator supports the BOOTP and RARP  
protocols. Use these protocols to obtain boot information from a UNIX  
host without requiring any manual set-up on the Remote Access  
Concentrator.  
BOOTP allows a diskless client to determine its IP address,  
the IP address of the server, and the name of the file to be  
loaded into memory.  
RARP maps a hardware address into an IP address.  
The ROMs invoke this system of acquiring boot information when a boot  
is initiated and the Remote Access Concentrator is not initialized. Under  
this condition, the Remote Access Concentrator first tries to get boot  
information via BOOTP or RARP.

Chapter 2 Installing the Model 5399 Remote Access Concentrator Module  
If all requests fail, the Remote Access Concentrator will return to the  
ROM monitor (if inTestmode) orcontinue the auto-initializingprocedure  
indefinitely (if in normal mode).  
BOOTP  
For a successful BOOTP retrieval, a bootpd must be running on a host  
on the same subnet as the Remote Access Concentrator (or have a  
correctly-configured router on the same subnet that supports BOOTP  
forwarding) and must have the appropriate information in the bootptab  
file. The Remote Access Concentrators BOOTP implementation adheres  
to rfc951, rfc1048, and rfc1084. A sample bootptab file entry used to  
initialize the Remote Access Concentrator named terminator looks like  
this:  
remoteannexdefault:\  
:sm=255.255.255.0:gw=132.245.22.66:\  
:hn:vm=auto:to=-18000:  
terminator:\  
:ht=1:ha=00802d004879:ip=132.245.22.226:\  
:tc=remoteannexdefault:  
In the previous example:  
sm is the subnet mask.  
gw is the load/dump gateway address.  
vm is the Vendor Magic Cookie.  
ht is host type (1=Ethernet).  
ha is the Remote Access Concentrator’s hardware address  
(Ethernet Address).  
ip is the Remote Access Concentrator’s Internet Address.

2-24  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Chapter 2 Installing the Model 5399 Remote Access Concentrator Module  
When the Remote Access Concentrator receives a BOOTP response with  
the sm, gw, and ip set, it sets the respective parameters: subnet_mask,  
load_dump_gateway, and inet_addr. The Vendor Magic Cookie must  
be set to auto. This indicates that bootpd should respond to the client  
(Model 5399 Remote Access Concentrator in this case) with whatever  
format the client requests; the Model 5399 Remote Access Concentrator  
(client) always makes requests with the Vendor Magic Cookie set to  
99.130.83.99.  
The bootpd adds the address of the host on which it is running as the  
Server Address in the bootp response message. The ROMs use the Server  
Address as the preferred load host and store it in the pref_load_addr  
parameter.  
The host running bootpd (the preferred load host) must also be  
running erpcd or tftpd.  
RARP  
If the Remote Access Concentrator does not receive a successful BOOTP  
response, it uses RARP to get the boot information. For a successful  
RARP retrieval, TCP/IP must be running on a host that is on the same  
subnetasthe Remote Access Concentrator, and the host’s ARP table must  
be initialized with the Remote Access Concentrator’s Internet and  
Ethernet addresses (see the arp man page for arp –s).  
The only boot information that RARP provides is the Remote Access  
Concentrator’s Internet address. The ROMs save this information in the  
inet_addr parameter. The ROMs use default information for the subnet  
mask and preferred load host. This means the ROMs will broadcast their  
requests.

Chapter 2 Installing the Model 5399 Remote Access Concentrator Module  
The host serving the Remote Access Concentrator its boot information  
must be running on the same subnet as the Remote Access Concentrator  
because the Remote Access Concentrator broadcasts BOOTP and RARP  
queries using the “this network” IP address, 255.255.255.255.  
If BOOTP and RARP fail, the Remote Access Concentrator transmits an  
IPX Advertisement Request for Service.  
If all requests fail, the Remote Access Concentrator returns to the ROM  
monitor (if in Test Mode) or continues the auto-initializing procedure  
indefinitely (if in Normal Mode).  
Manually Initializing the IP Address Parameters  
To configure the Remote Access Concentrator for your specific needs,  
the IP address parameters can be manually initialized by performing the  
following steps:  
1. Enter the addr command at the monitor prompt.  
The following prompt is displayed:  
Enter Internet address::  
2. Enter the IP address for the Remote Access Concentrator.  
You are prompted to enter the server subnet mask, preferred  
load host, preferred dump host, IP packet encapsulation, and  
load broadcast flag. The defaults are listed after each prompt.

Chapter 3  
ROM Monitor Commands  
T
his chapter describes the ROM Monitor commands that are available  
in Monitor Mode. Access these commands through a terminal connected  
to the service port (located on the front of the hub chassis).  
The ROM Monitor commands allow you to set a subset of the  
configuration (EEPROM) parameters. Some of these parameters, like the  
unit’sIP address, are required for booting the Model 5399Remote Access  
Concentrator; some parameters, like the broadcast address, are required  
if the network configuration differs from the supplied defaults. Table 3-1  
lists the ROM Monitor commands.  
Other parameters, although not required, are recommended for the  
Remote Access Concentrator’s initial boot. Setting these parameters,  
rather than using the assigned defaults, minimizes errors during the initial  
boot. For example, setting the parameter that defines the preferred load  
host enables the Remote Access Concentrator to load by requesting  
assistance from a specific host, rather than by broadcasting that request  
to all hosts on the subnet.  
After the Remote Access Concentrator has booted, you can define the  
same parameters you defined using the ROM Monitor, by using the  
host-based na utility, the local CLI admin command, or SNMP. The  
Remote Annex Administrator’s Guide for UNIX describes the na utility  
in detail. See Chapter 4for information on power-up and boot procedures.  
ROM Monitor commands generally provide data about a subsetof current  
configuration (EEPROM) parameters. When appropriate, they also  
display a prompt that allows the operator to change those parameters.

abbreviation that is not unique, an error message describing the command  
as ambiguous is displayed on the service port terminal.

Chapter 3 ROM Monitor Commands  
The Remote Access Concentrator must have an Internet (IP) address in  
its memory before it can load its operational image across the Ethernet  
via the IP protocol. Therefore, you must enter the IP address before  
booting the Remote Access Concentrator from a UNIX load host. If you  
do not define a subnet mask, the Remote Access Concentrator uses the  
generic mask for the specified IP address.  
The subnet mask must be set correctly for the network you are  
using or erratic operation will result (boot failure or ICMP  
"redirect" storms are likely results).  
The Remote Access Concentrator tries to boot from a preferred UNIX  
load host. If you do not define a preferred load host, the Remote Access  
Concentrator broadcasts its load request and loads software from the first  
host that responds.  
If the part of the IP address containing the network or subnet address  
differs from that of the preferred load or dump host, the host must be  
reached through a gateway (or router). The addr command prompts you  
for this gateway’s IP address.  
The Remote Access Concentrator uses the broadcast address parameter  
when loading a file. If this parameter contains a specific address (for  
example, 132.245.6.255), the Remote Access Concentrator uses onlythat  
addressforbroadcast. If thevalue isallzeroes(0.0.0.0),the ROMMonitor  
tries various combinations of broadcast addresses and subnet or network  
broadcasts. The Remote Access Concentrator broadcasts its request three  
times for each possible combination of broadcast addresses.

You can specify the IP encapsulation type as either ethernet for DIX  
Ethernet-II, or ieee802 for IEEE 802.2/802.3. The default IP  
encapsulation is ethernet. All systems that have Ethernet interfaces are  
IEEE 802.3 compliant, but very few actually do 802.3 packet  
encapsulation.  
Do not change this parameter unless you know absolutely that  
your Ethernet hosts are using 802.2/802.3 packet encapsulation.  
An incorrect encapsulation type prevents your Remote Access  
Concentrator from booting.

boot  
The boot command requests the loading of appropriate Remote Access  
Concentrator operating software from a cooperating host on the network  
or from Flash memory. The command syntax is:  
boot [–lv | filename]  
Co ntrol  
Typing the letter q or  
-C interrupts the boot.  
A successful boot disables the ROM Monitor.  
The boot command accepts a file name for the Remote Access  
Concentrator’s image. If the file name is not specified, boot displays the  
file name that was entered using the image command, and prompts for  
one. If you do not provide a file name, or have not defined one for the  
Remote Access Concentrator using the image command, boot requests  
the default oper.64.enet file.  
For more information on the image command, see “image” on  
page 3-17.  
The interface used for booting is determined by the sequence  
command.When SELF is selected, the Remote Access Concentrator  
checkstobe sure thattheselectedimage matcheswhatisinFlash memory.  
If it matches, the image in Flash memory is decompressed and loaded  
into RAM. If it doesn’t match, the Remote Access Concentrator uses the  
next interface specified by the sequence command.  
For more information on the sequence command, see “sequence”  
on page 3-22.

Chapter 3 ROM Monitor Commands  
The Remote Access Concentrator boots from the defined preferred load  
host. If the preferred load host is not defined or does not respond, the  
Remote Access Concentrator optionally broadcasts on the Ethernet and  
loads from the first host that responds, if the Load Broadcast flag is set.  
To initiate loading, the Remote Access Concentrator sends a load request  
message to the selected host. After receiving a response, the Remote  
Access Concentrator loads its operational code to RAM. When loading  
iscomplete, ittransferscontrol tothe newly-loadedprogram. The Remote  
Access Concentrator displays a symbol on the service port terminal for  
each data block received during the boot.  
When the Remote Access Concentrator begins to boot, it displays the  
load server host’s Internet address. If the unit does not boot successfully  
after several attempts, it displays a boot attempt failed message; if the  
unit has opened the boot file and an error occurs during the boot process,  
it displays a boot error report on the service port terminal and returns to  
the ROM Monitor. The boot error report can help determine the cause of  
the boot failure (see “Boot Error Report” on page 4-8).  
During a boot, the service port terminal may display four possible status  
symbols: “.” indicates received data blocks, “?” indicates unanswered  
requests, “*” indicates transmission errors, and “! ~XXXX~” is a status  
word from the Ethernet chip on the Annex indicating a serious problem  
with the Ethernet connection (if this symbol appears in your boot  
command display, contact technical support).

The statusword “! ~XXXX~”, where XXXX are four hexadecimal digits,  
decodes as follows:  
8000 = Command complete  
4000 = Chip is busy  
2000 = Command completed without error  
1000 = Command aborted issuance of an ABORT command  
800 = Late collision detected  
400 = Carrier lost  
200 = CTS lost  
100 = DMA underrun  
80 = Transmission deferred because link was busy  
40 = Collision detected during interframe spacing (SQE/Heartbeat  
detected)  
20 = Excessive collisions  
10 = Reserved  
The lowest nibble (bits 3 to 0) are a count of collisions during this  
transmission. For example:

Chapter 3 ROM Monitor Commands  
erase  
The erase command erases the contents of non-volatile memory  
(EEPROM memory). ErasingEEPROM restoresallparameterstofactory  
default values. The syntax is:  
erase  
The erase command prompts for confirmation before erasing the  
non-volatile (EEPROM) memory.  
The erase command does not erase the Ethernet address.  
Since the erase command erases the IP address, you may need  
to use the addr command to re-enter the Remote Access  
Concentrator’s IP address before reloading any software (if you  
are using BOOTP or RARP, you should not set the IP address).  
The erase command display looks like this:  
monitor:: erase

net  
The net command executes an Ethernet transceiver loopback test on the  
local area network. The command syntax is:  
net  
When you enter the net command, you are prompted for the segment as  
shown in the following example:  
monitor:: net  
Enter Segment to be used (1-6) [1]: 1  
This transceiver loopback test sends out a short test packet from the  
Remote Access Concentrator through the transceiver to test the integrity  
of the network.  
The Ethernet transceiver loopback test causes the Net LED to turn off. If  
the unit passes this test, the service port terminal displays PASSED, as  
shown in the following example.  
monitor:: net  
Enter Segment to be used (1-6) [1]: 1  
Network test - PASSED  
If the Remote Access Concentrator fails, the service port terminal

Chapter 3 ROM Monitor Commands  
ping  
The ping command sends an Internet Control Message Protocol (ICMP)  
mandatory ECHO_REQUEST datagram to elicit an ICMP  
ECHO_RESPONSE from a host or gateway. ECHO_REQUEST  
datagrams (pings) have an IP and ICMP header, followed by a structured  
time value and an arbitrary number of pad bytes that fill out the packet.  
The syntax for this command is:  
ping host_ip_address [data_size] [npackets]  
The host_ip_address entry is the Internet address of the host  
or gateway from which you wish to elicit a response.  
The optional data_size entry is the number of bytes sent in a  
datagram packet. The default value is 64 and the maximum  
value is 1024.  
The optional npackets entry is the number of packets to  
transmit. If you specify npackets, you must also specify a  
data_size.  
The ping command display looks similar to this:  
monitor:: ping 132.245.33.69  
Enter Segment to be used (1-6) [1]: 1  
PING 132.245.33.69: 64 data bytes  
If you enter the ping command without specifying an IP address, the  
display looks similar to this:  
monitor:: ping  
Enter segment to be used (1-6) [1}: 1  
IP address required, ie: ping 132.245.33.69\  
[data bytes] [npackets]  
When you enter the ping command, the following prompt is displayed:  
Enter Segment to be used [1]:  
To exit out of ping either wait for npackets to be transmitted or, at any  
point, type q. The ping statistics display upon exit.

ports  
The ports command tests the WAN interface port. The syntax is:  
ports  
To test the WAN port, the interface must be connected to a loopback plug.  
No external clocking is required.  
When invoked, the command displays a menu of options. The following  
is a sample screen display for a T1 (24 modems) or E1 (32 modems)  
version of the Remote Access Concentrator.  
monitor:: ports  
Some Important Notes:  
- These tests require the WAN port to have a loopback  
plug installed.  
- An even number of ports must be selected for the Modem  
Ports test because pairs of modems are connected  
together and data is looped back between them.

Chapter 3 ROM Monitor Commands  
sequence  
The sequence command edits the load/dump interface list. This list  
determines the order of the network interfaces the Remote Access  
Concentrator will use for loading and dumping. The default, net, uses the  
LAN interface. If the Remote Access Concentrator fails to boot using the  
first interface, it will try the next interface. The command syntax is:  
sequence [–d] | [interface[,interface]. . .]  
Specify the LAN interface by selecting net. Separate each interface with  
a comma or a space. Enter the interface list as an argument to the  
command, otherwise the service port terminal displays a list of available  
interfaces and prompts for a new list.  
In the following example, interfaces are assigned to the load/dump  
sequence list.  
monitor:: sequence  
Enter a list of 1 to 4 interfaces to attempt to use for  
downloading code or upline dumping. Enter them in the order  
they should be tried, separated by commas or spaces.  
Possible interfaces are:  
Ethernet:  
SELF:  
net  
self  
Enter interface sequence [net]:: self, net  
Interface sequence: self,net  
If SELF is specified as the first sequencing option, it is  
recommended that NET be included as a second sequencing  
option as shown in the example above.

Refer to Table 4-1 for a description of the LEDs located on the front of  
the Model 5399 Remote Access Concentrator Module.  
Table 4-1. Model 5399 Front Panel LEDs  
LED(s)  
Description  
Annunciator  
The Annunciator backlights the model number of the  
module and indicates, by its color, the operational  
condition of the module. The conditions are:  
Green - The module is performing normally.  
Amber - Some portion of the module has failed, or the  
module is being initialized.  
Off - The module is not receiving +5 volt power, or the  
power level is below the reset limit (4.65 volts).  
Segment  
Connection  
LEDs  
These LEDs indicate which backplane Ethernet LAN  
segments are being used. There are 12 green LEDs,  
labeled S1 through S12, for the 12 Ethernet segments.  
When an LED is illuminated, it indicates that the Remote  
Access Concentrator is connected to the corresponding  
backplane Ethernet LAN segment; when off it indicates  
that the corresponding backplane Ethernet LAN segment  
is not connected.  
Module Status  
LEDs  
Init - Turns green when the Remote Access Concentrator  
begins the initialization process after a power-up or reset.  
This is the first LED that lights after power-up or reset.  
The Init LED turns off after the diagnostics have  
successfully completed.  
Unit - Turns green after the Remote Access Concentrator  
passes the power-up diagnostics. Turns amber if the  
power-up diagnostics fail.  
Net - Turns green after the Remote Access Concentrator  
verifies that a valid Ethernet connection exists.  
Attn - Turns amber when the Remote Access  
Concentrator requires operator attention, that is, in  
Monitor Mode or when the diagnostic tests fail.

dumping a RAM image if there is a failure. The LED  
turns amber if a load error is detected.  
Network Status  
LEDs  
TEST - The network TEST indicator is ON (amber)  
when the WAN Interface is looped back. Loopback  
tests are activated either locally by the user or by the  
telephone company.  
SYNC - The green SYNC indicator is ON (green)  
when the WAN interface is synchronized with the  
received network signal and is receiving proper framing  
information.  
LOS - The LOS indicator is ON (amber) when the  
WAN interface is detecting invalid synchronization  
pulses on the network interface receiver. When an LOS  
condition exists, the WAN interface transmits a  
YELLOW alarm to the remote system.  
Alarm LEDs  
RED - The RED alarm indicator is ON (amber) during  
a locally detected carrier failure. During the RED alarm  
condition, a YELLOW alarm is transmitted across the  
telephone network.  
YELLOW - The YELLOW alarm indicator is ON  
(amber) when receiving a YELLOW alarm condition  
from the telephone network. This indicates a failure  
detected at the other end of the link (the Central  
Office).  
BLUE - The BLUE alarm indicator is ON (amber)  
when receiving an unframed, all-ones Alarm Indication  
Signal (AIS) from the network. This condition exists  
upon a loss of originating signal, or when any action is  
taken that would cause a signal disruption.

Chapter 4 Troubleshooting Procedures  
Table 4-1. Model 5399 Front Panel LEDs (continued)  
Port Usage LEDs  
The Port Usage LEDs, labeled 25%, 50%, 75%, and  
100%, indicate the approximate percentage of B  
channels that are being utilized. There are two sets of  
Port Usage LEDs, one set for each WAN Port. These  
LEDs are normally green. If all available B channels  
are in use, they turn amber until at least one call  
disconnects.  
During power-up and booting, it is more difficult to diagnose problems  
because they can originate in the Remote Access Concentrator, the  
Ethernet, or the load server host. However, the LEDs provide both a  
progress report and an error display to assist you in troubleshooting.  
If an error occurs, save the status of these LEDs. Technical  
support personnel can use this information to diagnose  
problems.  
Power-up and Boot Procedures  
The Remote Access Concentrator has two modes of operation: Normal  
ModeandMonitor Mode.NormalMode isthe standardoperationalmode.  
Monitor Mode is a diagnostic mode that provides access to the ROM  
Monitor commands.  
During its power-up and boot sequence, the Remote Access  
Concentrator runs a set of diagnostics. The system LEDs display the  
diagnostics’status. The pattern of the system LEDs identifies the error  
condition.  
Table 4-2 lists abnormal operating conditions reported by the LED  
displays, points to possible causes, and recommends corrective actions.

Chapter 4 Troubleshooting Procedures  
Boot Failures  
The procedures for troubleshooting a power-up failure established that:  
The hardware is functional.  
The Ethernet interface is functional.  
The Remote Access Concentrator can communicate with the  
Ethernet.  
If the Remote Access Concentrator still is not booted, you must pinpoint  
the problem. The boot error report can help in this process.  
The Remote Access Concentrator generates a boot error report  
only if it opens the boot file and an error occurs during the boot  
process.  
Generally, two problems cause boot failures:  
The Remote Access Concentrator is not configured properly.  
The load server host is not responding.  
The Remote Access Concentrator requests a boot image from a  
pre-defined load host or by broadcasting a boot request. When a host  
responds, the Remote Access Concentrator loads its operational image.  
The Remote Access Concentrator requires setting certain configuration  
parameters. Enter these parameters using the Monitor Mode commands  
for the initial boot sequence. See Chapter 3 for more information on these  
commands.  
If the problem is a non-responsive host, the boot error report displays that  
information under the Rsp T/O’sfield. Thisfieldindicatesthatthe Remote  
Access Concentrator timed out while waiting for a response to its boot  
request; if this field is empty, check the Remote Access Concentrator’s  
configuration parameters.

Chapter 4 Troubleshooting Procedures  
Boot Error Report  
If an error occurs, a Remote Access Concentrator boot error report is  
generated only if the Remote Access Concentrator has opened the boot  
file. The report is displayed using the following format:  
BOOT ERROR REPORT (for BFS files only)  
Boot attempt from host nn.nn.nn.nn:  
Errors from Last Open Request:  
0 ARP errors 0 ERPC layer errors 0 Aborts rx’d  
Errors from Last Read Request:

Errors from Last ERPC Layer Invocation:  
0 H/W errors 1 Msgs from wrong host 0 Rsp T/O’s 0 Msgs of wrong type  
TFTP error reporting complies with the standard, predefined  
TFTP error codes.  
The Remote Access Concentrator generates a boot error report for the  
Internetaddressfrom which ittried, andfailed, toboot. Table 4-4 contains  
a description of the Errors from the Last Read Request; and Table 4-3  
contains a description of the Errors from Last ERPC Layer Invocation.  
The error count pinpoints the error that caused the boot failure. For  
example, if the boot failed during a Read Request due to excessive  
Expedited Remote Procedure Call (ERPC) layer errors, the Errors from  
Last ERPC Layer Invocation lists only errors that occurred during the  
failed Read Request (see Table 4-3). The report does not list errors that  
occurred during any other Read Request (see Table 4-4) or during the  
Open Request (see Table 4-5).  
The Open Request and the Read Request layers communicate with the  
block file server (BFS) on the host. The ERPC layer resides below the  
Open Request and the Read Request layers. It is responsible for sending  
a given message to a specific host UDP port, and for receiving the correct  
response to that message from the port.

Table 4-3. Errors from Last ERPC Layer Invocation  
Error  
Description  
H/W errors  
The Remote Access Concentrator sensed a hardware error  
during message transmission or reception. This error  
indicates a fault with the Remote Access Concentrator LAN  
interface. Use the net command to isolate the problem (see  
“net” on page 3-19).  
Msgs from  
wrong host  
The Remote Access Concentrator received a message from  
an incorrect host. This indicates that the Remote Access  
Concentrator received, and ignored, an unsolicited packet.  
Rsp T/O’s  
The Remote Access Concentrator never received a  
correctly formatted response from the correct host, or any  
response from any load server hosts.  
Msgs of  
wrong type  
The correct host sent a message to the Remote Access  
Concentrator, but the message was not a correctly  
formatted response to the transmitted request.

Error  
Description  
ARP errors  
Address Resolution Protocol (ARP) errors indicate that  
the Remote Access Concentrator is configured to boot  
from a specified host, but the host would not transmit its  
Ethernet address to the Remote Access Concentrator.  
Possibly, the Remote Access Concentrator configuration  
includes the wrong IP encapsulation, or the subnet mask  
is misconfigured on the host or the Remote Access  
Concentrator.  
ERPC layer  
errors  
See Table 4-3.  
Aborts rx’d  
The host’s BFS transmitted an abort in response to the  
Remote Access Concentrator’s Open Request. This often  
means that the requested file does not exist on that  
server, or that it is installed in the wrong directory or  
with the wrong permissions. Run erpcd –D on the host  
to obtain more information.  
Correcting Remote Access Concentrator  
Parameters  
The followingparametersmustaccurately reflectboththe Remote Access  
Concentrator and the network environment in which it operates.  
Verify the Remote Access Concentrator’s IP address using the addr  
command. If your network configuration does not support the factory  
defaults, verify the following parameters using the addr command:  
The broadcast address.  
The subnet mask.  
The load/dump gateway address (which must be specified if  
the preferred load server host is located on another network  
or subnet).

Chapter 4 Troubleshooting Procedures  
The IP encapsulation type. All systems that have Ethernet  
interfaces are IEEE 802.3 compliant, but very few actually  
do 802.3 (LLC/SNAP) packet encapsulation. Use the  
default, Ethernet, unless you know absolutely that your LAN  
does 802.2/802.3 (LLC/SNAP) packet encapsulation.  
You can use the defaults for the name of the image file containing the  
Remote Access Concentrator’s software and the address of the preferred  
load server host. If the value for the image name is incorrect, the Remote  
Access Concentrator cannot boot. Correct the name using the image  
command. If the address for the preferred load server host is incorrect,  
the boot takes longer, since the Remote Access Concentrator has to  
broadcast for a host. Correct the load host’s address using the addr  
command.  
Confirm that the Remote Access Concentrator’s boot parameters are  
correct by using the appropriate ROM Monitor commands. Modify any  
boot parameters that are incorrect or missing. Boot the Remote Access  
Concentrator either by entering the boot command at the service port  
terminal, or by resetting the module.  
Load Server Host Not Responding  
The Remote Access Concentrator can boot from one of the following  
hosts acting as a load server host:  
A UNIX host on the LAN using BFS via erpcd.  
Another Remote Access Concentrator using BFS.  
Any host (UNIX or non-UNIX) using tftp.  
A Windows NT host using BFS via erpcd.  
The following subsections discuss troubleshooting for some of these load  
server hosts.

UNIX Host on the LAN  
When troubleshooting a UNIX host on the LAN, make sure that:  
The host is booted and functioning properly.  
The host can communicate with other network nodes using  
standard UNIX networking features and utilities.  
All Remote Access Concentrator software is installed  
properly on the host. See the Software Installation Notes that  
come with the Remote Access Concentrator software  
release.  
The erpcd daemon or tftp server (which loads the  
operational image to the Remote Access Concentrator) is  
running.  
InTestMode,erpcdontheloadserverhostdisplaysbootprogressreports.  
In Monitor Mode, the Remote Access Concentrator displays boot  
progress reports. The Remote Access Concentrator displays its reports  
onthe serviceportterminalthatinvokesitsMonitorMode;erpcd displays  
its reports on the UNIX terminal that invokes its Test Mode.  
When running erpcd, all paths are relative to the /usr/spool/erpcd/bfs  
directory for both boots and dumps. The /usr/spool/erpcd/bfs directory  
is a default pathname and can be changed.  
1. To place erpcd on the load server host into Test Mode, kill  
the erpcd program (requires superuser privileges) and  
restart it using the –D option:  
# /usr/annex/erpcd –D5  
2. Place the Remote Access Concentrator into Monitor Mode.  
(This resets the Remote Access Concentrator, so warn users  
before you do it.) Then, at the monitor prompt, enter:  
monitor:: boot -v

When the Remote Access Concentrator boots in Monitor Mode, the  
service port terminal displays the load server host’s Internet address, and  
indicates whether it receives a response to its Open File Request and to  
any of its Read File Requests. The host’s progress report indicates receipt  
of any File Server Requests and its responses to such requests.  
The host displays erpc_return 0 if it successfully receives a request and  
is sending out an affirmative response. If any Remote Access  
Concentrator-related files are missing or cannot be installed, contact  
technical support.  
Windows NT Host on the LAN  
When troubleshooting a Windows NT host on the LAN, make sure that:  
The host is booted and functioning properly.  
The host can communicate with other network nodes using  
standard Windows NT networking features and utilities.

When the Remote Access Concentrator boots in Monitor Mode, the  
service port terminal displays the load server host’s Internet address, and  
indicates whether it receives a response to its Open File Request and to  
any of its Read File Requests. The host’s progress report indicates receipt  
of any File Server Requests and its responses to such requests.  
The host displays erpc_return 0 if it successfully receives a request and  
is sending out an affirmative response. If any Remote Access  
Concentrator-related files are missing or cannot be installed, contact  
technical support.  
Another Model 5399 Remote Access Concentrator Module  
When troubleshooting a Model 5399 configured as a load server host:  
1. Use ping from any host on your network to make sure the  
Model 5399 Remote Access Concentrator can be reached.  
2. Either use telnet or na to verify the unit’s configuration.  
The Remote Annex Administrator’s Guide for UNIX provides more  
information on these commands.  
A Model 5399 that has been reconfigured as a load server host, but not  
rebooted, cannot boot another Model 5399 on the network. Rebooting  
the Model 5399 load server host ensures that the parameters are set.  
Do not set the preferred dump address to point to another Model 5399  
Remote Access Concentrator. Set it to a host address, or to 127.0.0.1 to  
disable dumping.

Chapter 4 Troubleshooting Procedures  
Remote Access Concentrator Dumps  
The Remote Access Concentrator dumps its memory image to a host  
running load server software when certain software or hardware events  
occur.  
Dump files are generated for use by technical support personnel  
only.  
Events that trigger Remote Access Concentrator dumps are:  
Non-recoverable hardware or software errors.  
Software fails to reset the Remote Access Concentrator’s  
watchdog timer.  
Software fails one or more internal consistency checks.  
Hardware detects an internal fault.  
The Remote Access Concentrator sends a dump file to a preferred load  
dump host. If you do not define this host by specifying an address, the  
Remote Access Concentrator broadcasts a request and dumps to the first  
host that responds.  
The Remote Access Concentrator sends a dump to the /usr/spool/erpcd/  
bfs directory on the dump host. The /usr/spool/erpcd/bfs directory is a  
default pathname and can be changed. The receiving Remote Access  
Concentrator assigns a unique file name for each device that it receives  
a dump from but not for each crash dump.  
Rename any crash dumps that you want to save. Erpcd  
overwrites crash dumps if the same unit dumps again.  
The assigned name depends on the number of characters per file name  
that the dump host supports. For hosts supporting file names longer than  
14 characters (e.g., most modern UNIX hosts), dump files are named  
dump.addr. The file extension addr is the Remote Access  
Concentrator’s IP address.

Download from Www.Somanuals.com. All Manuals Search And Download.  
     
Chapter 4 Troubleshooting Procedures  
For hosts that may limit file names to 14 characters (e.g., System V hosts),  
a dump creates two additional directories under /usr/spool/erpcd/bfs.  
The name of the first directory is dump; the second directory uses the  
Remote Access Concentrator’sIP networkaddress asits name. The dump  
file uses the Remote Access Concentrator’s IP host address as its name.  
For example: /usr/spool/erpcd/bfs/dump/192.9.200/5.  
The tftp dump names are user-defined. If a name is not  
specified, the Remote Access Concentrator uses the bfs  
convention.  
Each dump file contains a complete image of the Remote Access  
Concentrator RAM memory and hardware state. The amount of space  
required for a dump file varies according to the port configuration. The  
ROM Monitor config command displays the amount of memory for the  
Remote Access Concentrator.  
Table 4-6 shows sample dump file names. All pathnames are relative to  
the file /usr/spool/erpcd/bfs.

Chapter 4 Troubleshooting Procedures  
Conditions for Replacing a Module  
Replace a Remote Access Concentrator with another module of the same  
type under any of the following conditions:  
If the annunciator on the module front panel remains off,  
indicating that the module is not receiving +5 volt power or  
that the power level is below the reset limit (4.65 volts) when  
other modules in the hub are receiving normal operating  
power. For more information, see Table 4-2.  
If the annunciator remains amber, indicating that some  
portion of the module has failed and a check of the self-test  
messages indicates that the problem cannot be fixed. For  
more information, see Table 4-2.  
Module Configuration Management  
Each module installed in a Model 5000 chassis operates according to  
software parameter values and hardware option settings. You can use  
these to customize module operation for that particular hub. This  
combination of software and hardware values is the module  
configuration, of which there are actually two types:  
“Primary” configuration, which is the set of base values built  
into the module at the time it is manufactured. A user cannot  
change this configuration.  
“Default” configuration, which is the permanent  
configuration plus any changes to jumper or switch settings.  
The default configuration is valid for any hub slot at any  
time. Each module must have a default configuration. This  
configuration is stored in two places: on the module itself  
and on the supervisory module. You can change this  
configuration through a network management module  
(NMM) or through a terminal connected to the chassis  
service port.

Download from Www.Somanuals.com. All Manuals Search And Download.  
             
Chapter 4 Troubleshooting Procedures  
The supervisory module, located in slot 0 of the 5000 hub, performs  
several functions for the hub and the modules installed in the hub. The  
supervisory module stores the primary configurations of all modules  
installed in the hub. Each user-installed module also stores a working  
copy of its configuration information. When a change is made to this  
working copy, the module stores the new user configuration in its onboard  
nonvolatile memory.  
The supervisory module periodically polls user-installed modules in the  
hub across the Common Management Bus (CMB). As part of the poll,  
the NMM collects module configuration information and stores the  
information in its local nonvolatile memory for use in comparing and/or  
restoring a module configuration after a power cycle or reset.  
What happens to a module when it is inserted in the hub depends on a  
combination of conditions:  
If you remove a module, change jumper settings, and  
reinsert the module in its original slot, the new jumper  
settings take effect immediately. The supervisory module  
records the new configuration information in its nonvolatile  
memory.  
If you replace a module in a slot with a different type of  
module, the new module is directed to use its default  
configuration.  
If the supervisory module is not operational, a module  
whose configured slot number matches its installed location  
can use its own stored configuration; otherwise, the module  
reverts to its default configuration.

Chapter 4 Troubleshooting Procedures  
To preserve the configuration parameters of the Remote Access  
Concentrator module you are replacing, follow the procedures in  
“Preparing for a Hot Swap” on page 4-19 (below) and “Completing the  
Hot Swap” on page 4-22.  
Verify that the backplane segment bank selector is set for the  
correct segment bank before installing a replacement module.  
For more information on jumper and switch settings, see  
Chapter 2.  
Preparing for a Hot Swap  
The Remote Access Concentrator can be inserted into or removed from  
a chassis without interrupting service to other modules within the System  
5000 hub. This ability is referred to as “hot swapping.”  
The Remote Access Concentrator holds 64KB of configuration  
information in EEPROM. This information is periodically sent to the host  
server to be saved in a file. During a hot swap, the new Remote Access  
Concentrator reads in this file at boot time and overwrites its EEPROM  
with the configuration information from the Remote Access Concentrator  
it is replacing. The new Remote Access Concentrator then functions as  
the previous Remote Access Concentrator, except for the LAT key, which  
needs to be reprogrammed.  
If no EEPROM overwrite is desired when hot swapping, select  
default values for that slot from the supervisory module on the  
service port terminal.

Chapter 4 Troubleshooting Procedures  
There are two methods of writing the EEPROM information to the host  
file:  
Whenever a change is made to EEPROM, a 5 minute timer is  
started. When the timer expires, the contents of the  
EEPROM memory are copied to an internal buffer in the  
Remote Access Concentrator RAM and encrypted. The file  
is then transferred to the host specified in the configuration  
parameter pref_dump_addr. The filename used to store the  
EEPROM information on the host is params.n.n.n.n (where  
n.n.n.n is the IP address of the Remote Access  
Concentrator).  
In addition, writing the EEPROM information to the host  
can be forced (bypassing the 5 minute timer) by using the  
Remote Access Concentrator’s superuser cp -e command.  
This can be done at any time and typically is done if you  
have just completed making changes to one of the  
configuration files or some of the configuration parameters.  
It will be necessary to configure the replacement Remote Access  
Concentrator to define the LAT key, because it isn’t restored during a hot  
swap.  
For the hot swap to be successful, the module being replaced and the new  
module must both be registered for the same software options.

Chapter 4 Troubleshooting Procedures  
Removing a Module  
To remove a Remote Access Concentrator, follow these steps:  
1. Using the flat-tip screwdriver, loosen the two captive  
retaining screws on the module until they pop free of the  
chassis.  
2. Push the top and bottom inserter/extractor levers away  
from the center of the Remote Access Concentrator front  
panel to release the module from the backplane connector.  
3. Slide the module out of the chassis.  
Grip the front panel with one hand while supporting the bottom  
of the module with the other hand.  
4. Place the module on an antistatic mat.  
If a module is removed from the chassis permanently or for more than a  
few minutes, you should install a filler panel on the empty chassis slots  
to maintain the cooling air flow within the chassis.  
The removed Remote Access Concentrator retains all of its set  
parameters, including the IP address. If you reuse this module  
elsewhere without removing this IP address, you will have  
duplicate IP addresses on your network.

Chapter 4 Troubleshooting Procedures  
Completing the Hot Swap  
To complete the hot swap of the Remote Access Concentrator:  
1. Verify that the jumper settings on the replacement module  
are the same as the settings on the original module.  
2. Use the procedures outlined in Chapter 2 to insert the  
replacement module into the System 5000 chassis.  
3. Boot the replacement Remote Access Concentrator.  
The saved EEPROM information is read by the Remote Access  
Concentrator at boot time only in a hot swap situation. The  
Remote Access Concentrator compares the “board serial  
number” field (in the supervisory module nonvolatile memory)  
against its internal serial number. After loading the operational  
image, the initialization process sets up the network interface  
and then reads the params.n.n.n.n file from the host server, and  
places it in local memory. The EEPROM file contents are  
decrypted and written to the EEPROM. The buffer containing  
the files is then discarded. This process may take several  
minutes to complete.  
4. If applicable, obtain a new LAT key and enter it.
