CHAPTER 1: OVERVIEW  
The two slots just under the power supply contain switching modules,  
one slot for the active switching module and one slot for the redundant  
switching module.  
Switching Module  
The switching module is the core switching engine of the CoreBuilder  
7000 family ATM switch, controlling and monitoring passive backplane  
and ATM activity. The switching module has a control port for connection  
to a terminal, a management port for connection to a network  
management station, and a service port for use by 3Com technicians.  
The next four slots contain interface modules. These can be of many  
different types; some are shown in the figure (see the CoreBuilder 7000  
Family ATM Switches User Guide for details).  
Interface Module  
Fans  
For ventilation a fan tray with 6 fans is located at the left side of the unit.

Redundancy in the  
CoreBuilder 7000  
Family ATM Switch  
The CoreBuilder 7000 family ATM switch is designed to meet the  
requirements of environments where network interruptions cannot be  
tolerated. The CoreBuilder 7000 family ATM switch platform has a fully  
redundant design, with dual load-sharing power supplies and redundant  
switching engines. All CoreBuilder 7000 family interface cards and  
switching engines are hot swappable to ensure continuous operation  
For information about determining the required power supply for various  
CoreBuilder 7000 family ATM switch installations and providing  
redundancy for various power loads see “Redundant Power Supply” on  
page 7-1.  
For information about using the redundant switching module see  
“Redundant Switching Module” on page 7-9.  
In addition to hardware redundancy, the CoreBuilder 7000 family ATM  
switch also provides redundant LANE services which are managed by the  
Transcend Network Management System. Each switch contains a  
complete set of LES and LECS functionality. In case of failure, LANE  
services can be transferred to another CoreBuilder 7000 family ATM  
switch elsewhere in the network.

Safety Precautions  
Read the following safety precautions carefully to reduce the risk of  
electric shock and fire.  
All servicing should be undertaken ONLY by qualified service  
personnel. There are no user serviceable parts inside the unit.  
The CoreBuilder 7000 family ATM switch internal power supply  
provides for automatic selection of either 100-120 VAC or 200-240  
VAC, 60/50 Hz, as indicated on the safety label adjacent to the power  
inlet. ENSURE that the available voltage supply at the mains is within  
one of these two ranges.  
DO NOT operate the unit in a location where the maximum ambient  
temperature exceeds 40 degrees C.  
Ensure that the chassis ventilation openings in the unit are NOT  
BLOCKED.  
DO NOT plug in, turn on or attempt to operate an obviously damaged  
unit.  
Unplug the power supply cord from the wall socket BEFORE  
attempting to remove and/or replace the power supply.  
The system has a redundant power supply option. Disconnecting one  
power supply cord disconnects one power supply module only. To  
isolate the unit completely from the mains, disconnect all power  
supply cords.

Safety Precautions  
When handling replacement parts, 3Com recommends that you always  
use a wrist strap connected to a proper ground. This helps prevent the  
module from being damaged by electrostatic discharge. Additionally,  
when not in use, the module should be stored in an antistatic bag.  
If the system is powered on when you are replacing a module, do not  
insert any metal objects, such as a screwdriver or a finger with jewelry, in  
the open slot. This could cause burns or other bodily harm, as well as  
system damage.  
Vorsichtsmaßnahmen  
Wenn Sie Ersatzteile handhaben, benutzen Sie immer ein Band am  
Handgelenk, daß gut geerdet ist. Das hilft vermeiden, daß das Ersatzteil  
durch elektrostatische Entladung beschädigt wird. Darüber hinaus sollte  
ein Modul, wenn nicht benutzt, in einem antistatischen Beutel  
aufbewahrt werden.  
Steht das System unter Strom, wenn sie ein Modul installieren oder  
auswechseln, führen Sie keine Metallgegenstände, wie einen  
Schraubenzieher oder einen Finger mit Schmuck in den offenen Schlitz  
ein. Das könnte zu Verbrennungen oder anderen Körperschäden führen,  
sowie auch zu Schäden am System.  
Mesures de sécurité  
Lors de la manipulation des pièces de rechange, 3 Com recommande de  
toujours utiliser une bande attachée au poignet et reliée à la terre. Cela  
aidera à éviter que la pièce ne soit endommagée par une décharge  
électrostatique. De plus, lorsqu'il n'est pas utilisé, le module doit être  
conservé dans un emballage antistatique.  
Si le système est alimenté lors de l'installation ou du remplacement d'un  
module, ne jamais insérer d'objet métallique tel qu'un tourne-vis ou un  
doigt portant un bijou dans la fente. Cela est susceptible de provoquer  
brûlures ou autres dommages corporels, et d'endommager le système.

Setting up Switch This section describes procedures for installing and setting up both a  
main and redundant switch module together.  
Module Redundancy  
Two different setup procedures are described. The first procedure covers  
setting up the main and redundant switch module hardware redundancy  
without setting up LANE redundancy. This procedure only requires  
operating the Local Management Application (LMA). The LMA is  
described in the CoreBuilder 7000 Family ATM Switch User Guide. The  
second procedure sets up the main and redundant switch module  
hardware redundancy as well as LANE redundancy. It requires both the  
LMA and the Transcend Enterprise Manager.  
There are two situations where you would use the procedures of this  
section:  
1 The initial installation of main and redundant cards.  
2 The main card in the first slot has failed and the redundant card in the  
second slot has taken over as the main card. The failed card in the first  
slot has been replaced by a new card and this new card is now the  
redundant one.

5 Insert the main switch module in slot 1.  
6 Wait five minutes for configuration information to pass between the two  
switch modules (see “Switching Module Configuration Database” on  
page 7-10 for a list of configuration items that pass between the switch  
modules).  
7 Reboot the CoreBuilder 7000 family ATM switch using the LMA menu  
sequence:  
(1) SYS / (7) RBO.  
The switch module in slot 1 becomes active.

Setting up Switch This section presents a procedure for setting up both switch module  
Module Redundancy hardware redundancy and LANE redundancy in the same session. Both  
and LANE the LMA and the Transcend Enterprise Manager are used.  
Redundancy  
General Description of the Procedure  
The following is a general description of the procedure for orientation  
purposes only. When you perform the procedure, use the detailed steps  
in the following sections.  
1 Install both switches in chassis and run RESETCFG.BAT on each one.  
Connect Ethernet ports of each switch module and install at least one  
interface card in the chassis.  
2 Configure the first switch using the Integrated Fast Setup of the LMA and  
do not reboot the switch in the Integrated Fast Setup.  
3 Reboot the switch after one minute using the LMA menu.  
4 Answer “no” to the prompt “Erase the setup parameters?” and use the  
LMA to check that all configuration parameters (i.e., database, IP, NNI  
etc.) have passed successfully to the second switch module.  
5 Configure LANE redundancy in the first switch using the Transcend  
Backbone and Services Setup window and close the window when  
finished.  
6 Reboot the switch after one minute  
7 Configure LANE redundancy in the second switch module using the  
Transcend Backbone and Services Setup window and close the window  
when finished.  
8 After one minute use the MIB browser to check the LECS order list and  
the Backbone and Services Setup window to check the LECS database.  
9 Reboot the box.  
10 Check the second switch using the MIB browser to check the LECS order  
list and the Backbone and Services Setup window to check the LECS  
database.

Preparatory Steps  
Carry out the following preparatory steps.  
1 Install main and redundant switch modules in the switch module slot 1  
and slot 2 respectively (see “Installing a Switch Module” on page 4-5). Do  
not run the Integrated Fast Setup yet.  
Each time the switch is rebooted during this procedure the cards change  
roles. The main card becomes the redundant card and vice versa. The  
main card can always be identified by its ACT LED flashing once every  
two seconds. The ACT LED of the redundant card flashes at a lower rate.  
2 Verify that at least one interface card of any type is installed in the  
CoreBuilder chassis in any interface card slots 3-6. Data is transferred  
between switch modules via a communications chip on an interface card.  
3 Verify that the Ethernet management ports in both switches are  
connected to the NMS station. They can either be connected through a  
hub to the NMS station or through an Ethernet interface card in the same  
chassis, such as the CoreBuilder 7400 High Density Ethernet/ATM  
interface card, to the NMS station.  
During the procedure you will need to verify connectivity between the  
NMS station and the switch by pinging the switch module from the NMS  
station.  
Connectivity between the switch module and its attached devices is  
established by an RARP transmitted by the switch module when it boots.  
The RARP causes a device to learn the MAC address of the switch  
module. However, there are certain devices, for example, a Solaris station,  
which will not learn a new MAC address for an IP when one already  
exists. If you are using one of these devices as an NMS station, and you  
are unable to ping the switch module, try erasing the switch module’s  
MAC address from the device’s ARP table and ping again.  
4 Verify that the RS-232 terminal line is connected to the console port on  
the main switch module.  
Procedure Execution  
1 Reset the configuration of both switch modules by executing the  
RESETCFG.BAT file supplied with your software.  
Do not use the LMA menu (1) SYS / (2) RES to reset the switch module  
configuration.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
4-10  
CHAPTER 4: INSTALLING AND CONNECTING COREBUILDER MODULES  
To execute the RESETCFG.BAT file proceed as follows:  
a Perform the LMA command (1) SYS / (3) LOA / (3) LCL / 1 to put the  
system in Load Mode: Load.  
b Reboot the switch using the LMA menu command: (1) SYS / (7) RBO.  
The switch will reboot in debug mode.  
c Transfer the RS-232 cable to the service port of the main switch  
module.  
d From a DOS window on the LMA terminal execute  
> resetcfg com speed  
where “com” is the communications port you are using and “speed”  
is 115200 for a CoreBuilder 7000HD switch module and 57600 for a  
CoreBuilder 7000 switch module.  
e Transfer the RS-232 cable to the service port of the redundant switch  
f
Repeat step d)  
g Transfer the RS-232 cable to the console port of the main switch  
module.  
Switch Module Redundancy Setup  
2 Set up the main switch module using the Integrated Fast Setup (see  
“Integrated Fast Setup” on page 6-3). Do not reboot the switch from the  
Integrated Fast Setup procedure (answer “no” to the prompt).  
The main menu appears.  
3 Wait for one minute to allow the configuration data to transfer from the  
main switch module to the redundant switch module.  
4 Reboot the switch using the LMA menu sequence: (1) SYS / (7) RBO. This  
causes the configuration data to be recorded in flash memory and also  
causes the redundant switch module to become the main switch module.  
5 After the switch reboots, answer “no” to the prompt: “Do you wish to  
erase the setup parameters”.  
6 Run the Integrated Fast Setup procedure as in step 2) to verify that the  
setup parameters have been transferred correctly to the second switch  
(the Integrated Fast Setup procedure now displays the setup parameters  
resident in the second switch module). Press Enter repeatedly to verify  
these parameters; do not enter new values.

Switch Module 4-11  
7 Verify that the ELAN names in the LECS database are identical in both  
switch modules. Use menu item (2) LEM/(1) LCS/(5) LNT to check that the  
LECS database of the second switch includes the ELAN name of the first  
switch. For example, Elan6666_0 - Elan6666_15  
LANE Redundancy Setup  
8 Verify connectivity between the switch module and the NMS station by  
pinging the switch module from the NMS station.  
9 Load the Transcend application and open the Wizard Tool from the  
ATMvLAN tool bar  
10 Open the Backbone and Services Window.  
11 Configure the LECS order as desired and press the Apply button.  
12 Configure the LECS database. Add all the primary and redundant ELAN  
names desired to the LECS database and press Apply. Make a list of the  
ELAN names you have selected. You will need them for setting up the  
other switch module.  
13 When finished, close the Backbone and Services window.  
14 Wait one minute to allow the LECS order database to transfer to the  
other switch module.  
The LECS ELAN database does not transfer automatically.  
15 Reboot the switch using the LMA menu sequence: (1) SYS / (7) RBO.  
The purpose of this step is to make the first switch module active in order  
to set up the LANE services there.  
16 After the first switch boots, check its connectivity with the NMS station as  
in step 8).  
17 Perform steps 10) and 12) using the same list of ELANs.  
18 Wait one minute.  
Verifying LANE Redundancy Setup  
19 Use the MIB browser under the Transcend tools menu and browse  
through the MIB to verify that all the information regarding the LECS  
order list has been transferred correctly.

Replacing a 4-Port To replace individual daughter cards, or to replace the entire interface  
Interface Module module:  
1 Disconnect the cables from the card's ports. Ensure that there is a record  
of where the cables are attached so that you can correctly re-connect  
them to the new card.  
2 Loosen the screws at the extreme right and left of the card, near the  
insert/eject handles.  
3 Grasp the insert/eject handles of the card you want to replace and push  
them outward. This ejects the card. You may have to apply considerable  
force to the handles. You will hear a “click” to indicate that the  
connections have separated, and the card will slide slightly forward out of  
the CoreBuilder chassis.  
4 If you are replacing the entire interface card, remove the new card from  
its antistatic bag. Place the old card in the antistatic bag and set it aside in  
a safe place.  
Fan Tray

Connecting the The CoreBuilder 7000 family ATM switch can be configured via the LMA  
Control Terminal using the Administration Console terminal (VT100) or terminal emulator  
(Windows). To connect a terminal to the CoreBuilder 7000 family ATM  
switch control port:  
1 Prepare an RS-232 shielded cable (9 pin-to-9 pin or 9 pin-to-25 pin, as  
dictated by the terminal you wish to use).  
2 Configure the terminal: 19200 baud, 8 data bits, 1 stop bit, no parity,  
xon/xoff flow control.  
3 Push the DCE side of the cable onto the Control port of the switch  
module and screw it into place.  
4 Connect the other end of the cable to the terminal.  
In case you have installed a redundant switch unit, it is sufficient to  
connect the RS-232 line to either the active switch control port or to the  
redundant switch control port.  
Connecting to the The Ethernet port is used for connecting directly to a Transcend NMS  
Ethernet Port terminal for management purposes.  
In case you have installed a redundant switch module, its Ethernet port  
must also be connected directly to the Transcend NMS terminal.  
Another way of connecting the Ethernet port to an out-of-band Ethernet  
network is to connect it to a CoreBuilder 7200 Ethernet/ATM Interface  
Card or a CB7400 High Density Ethernet/ATM Interface Card installed in  
the same chassis.

System States and LED indicators are located on the front panels of the CoreBuilder 7000, its  
Switching Module power supply, switching modules, and interface modules. These LEDs  
LEDs indicate the current system state of the CoreBuilder unit and its  
components. Front panel LEDs can be extremely useful in determining the  
cause of specific problems.  
The system state in which the CoreBuilder 7000 unit is currently  
operating is displayed by the switching module system status LEDs.  
Referring to Figure 5-1, these are the three LEDs: PWR, FAIL, and ACT(ive)  
on the left side of the LED panel. Table 5-1 shows the correlation  
between the current system state and SYS LEDs display. For example,  
during normal operation the PWR LED is on, the FAIL LED is off and the  
ACT LED is flashing. The LEDs on the right side of the panel indicate the

System Power-on  
This section describes the stages of system power-on of the CoreBuilder  
7000 family ATM switch.  
Software Loading Apply electrical power to the system by inserting the power cord in the  
and Diagnostics power supply unit. The power supply indicator lights and the CoreBuilder  
7000 family ATM switch automatically runs diagnostic software. This  
software verifies that every component in the system is fully functional  
before the system becomes active on the network. Diagnostics should  
take sixty seconds or less.  
If any component fails power-on diagnostics, the system either fails to  
power on or it keeps faulty modules off-line. Once the system comes up,  
you can check to see which modules, if any, have failed diagnostics by  
checking the LED panels; in-depth information is available by viewing the  
system configuration screens on the administration console.  
Indicators All interface and switching unit indicators light at the start of the  
power-on diagnostic sequence, then go out briefly. General activity LEDs  
light up as the system checks the switching and interface modules.  
Finally, individual port indicators go on as the system discovers active  
connections residing on the interface modules. The 10BaseT indicator on  
the interface module is on during normal function, even if there is no  
active 10BaseT management link.

Integrated Fast  
Setup  
This section describes the Integrated Fast Setup procedure and contains  
the following topics:  
Setup Modes  
Setup Procedure Sections  
Entering Data  
Navigation Aids  
Integrated Fast Setup Operation  
You use the Integrated Fast Setup procedure to configure the minimum  
set of parameters needed to enable the CoreBuilder 7000 family ATM  
switch and its attached devices to function in the network.  
With this procedure you can configure both the CoreBuilder 7000 family  
ATM switch card and all CoreBuilder 7X00 interface cards installed in it in  
one session.  
In certain cases you will need to use the Fast Setup procedure of  
individual CoreBuilder 7X00 interface cards, in addition to the Integrated  
Fast Setup procedure, to correctly configure your system.  
This section presents the Integrated Fast Setup of the CoreBuilder 7000  
family ATM switch card. It also explains when to use the Integrated Fast  
Setup of the CoreBuilder 7000 family ATM switch card and when to use  
the Fast Setup of an individual Corebuilder 7X00 interface card. For  
detailed information about how to use the Fast Setup of an individual  
Corebuilder 7X00 interface card see the User Guide of the specific  
interface card.  
Chassis-oriented Setup  
The Integrated Fast Setup procedure is based on the concept that the  
CoreBuilder 7000 family ATM switch chassis together with its installed  
interface cards is viewed as an integrated unit. The advantage of this  
point of view is its simplicity: it is not necessary to remember in which slot  
each interface card is installed or even which type of interface card is  
installed. Attention is focussed on configuring the ports of the chassis.  
The procedure automatically determines the ports that are available in the  
chassis and presents them by type (Ethernet, Fast Ethernet, ATM) for  
configuration. The port location is displayed by the notation <slot.port>  
For example <3.1> refers to slot #3, port #1.

ONFIGURING THE ORE UILDER  
Chassis-wide vLANs  
With the Integrated Fast Setup, Virtual LANs (vLANs) can be created  
across the entire chassis. vLANs are set up in two stages. First, in the LE  
Client section, a number of potential vLANs are created according to the  
requirement of the network. Next, in the Virtual Network Configuration  
section, the potential vLANs become actual vLANs by having ports  
assigned to them.  
You need to define an administration “admin” vLAN to maintain SNMP  
connectivity to each device in the network. Using the Integrated Fast  
Setup you define one admin vLAN for the chassis; there is no need to  
define separate admin vLANs for each interface card.  
Note that from software version 3.5 on, the “admin” vLAN can now be  
called by any other name providing the same name is used consistently in  
the CB7000 and in all installed CB7X00 interface cards. When using the  
Integrated Fast Setup, the name for the admin vLAN which is specified for  
the switch module will be automatically chosen for the other modules  
housed in the same CoreBuilder 7000 family ATM switch chassis,  
overriding any existing admin vLAN names.  
Setup Modes The Integrated Fast Setup provides two setup modes: the “Full” setup  
mode and the “Switch” setup mode.  
Full Setup Mode  
The Full setup mode configures both the CoreBuilder 7000 family ATM  
switch and the installed interface cards. It sets the required parameter  
values in all the installed interface cards. The Full setup mode presents  
only the most critical parameters; default values are assumed for the  
remaining parameters.  
This method is recommended for most users, especially for initial setup.  
Only those systems that require specific parameter settings in one or  
more of the installed interface cards will require the Switch setup mode  
described in the next section.  
Switch Setup Mode  
The Switch setup mode focuses only on the CoreBuilder 7000 family ATM  
switch and its ATM ports. The Switch setup mode is provided to allow you  
to retain special settings in the interface cards; it does not allow any of  
the installed interface card configurations to be changed. If you wish to

alter the settings in an interface card you can use the Fast Setup of that  
interface card after you are finished using the Switch setup procedure.  
Setup Mode Selection  
If one of the following situations is detected, the operator is prompted to  
choose between the Switch and Full setup modes:  
A Subnet Mask, Default Gateway or NMS Address different from that  
of the CoreBuilder 7000 family ATM switch  
A vLAN whose ATM connection is set to “No”  
The name of the ELAN to which the default admin port (Port #1 in  
each slot) is attached is not the same in all interface cards.  
If none of these situations is detected, Full setup mode is automatically  
selected.  
If Full setup is selected, the parameters in the interface cards revert to  
their default values.  
Setting Special Parameters  
If one or more individual interface cards requires one of the special  
situations referred to in the previous section or needs to remain  
unaltered, you need to do one of the following:  
Use the Switch setup mode of the Integrated Fast Setup to set up the  
CoreBuilder 7000 family ATM switch only and then use the Fast Setup  
of each installed interface card separately.  
Use the Full setup mode of the Integrated Fast Setup to configure the  
CoreBuilder 7000 family ATM switch and all installed interface cards  
and then use the Fast Setup for the particular interface card in order to  
restore its special parameter values.

Interface Type Section This section prompts you for the ATM  
interface type configuration of the ports on the Interface Modules which  
are installed in the CoreBuilder 7000 family ATM switch chassis.  
There are three interface types: UNI, E-IISP and IISP. The UNI type is  
normally used when an edge device is connecting to a switch, the E-IISP  
type is normally used when connecting to another CoreBuilder 7000 or  
9000 switch, and the IISP type is used to connect to a device which does  
not recognize the E-IISP protocol used by the CoreBuilder 7000 family  
ATM switch such as switches of other vendors.  
To enter the interface type configuration:  
1 At the NNI type of port prompt, enter the NNI type for the port you just  
specified. Enter “U” for UNI, enter “E” for IISP, or enter “I” for IISP.  
2 Repeat step 2 until you have specified the interface type for all of the  
ports that are in the Corebuilder 7000 family ATM switch chassis.

you want to be active in the network. In the Virtual Network  
Configuration section, you will assign Ethernet ports to the ELANs you  
have named in this section to create vLANs. Until then, the ELANs are  
considered potential ELANs.  
You can enter the names of resident ELANs of the switch you are setting  
up and you can enter names of ELANs from other devices in the network.  
You can define any number of potential ELANs. To end the sequence,  
press Enter.  
The names of the ELANs resident on a particular switch all have the form  
elanXXXX_n where “XXXX” is a number unique to the switch and “n” is  
the sequential number of the ELAN. This is the form you need to use for  
ELANs that you enter in this section (except for the admin ELAN).  
You are first prompted for the name of the admin vLAN. The default  
name displayed is the name of the admin vLAN of the CoreBuilder 7X00  
which is installed in the highest occupied slot in the CoreBuilder chassis.  
You can change it if you wish.  
The name for the admin vLAN which is specified in this section will be  
automatically chosen for the other modules housed in the same  
CoreBuilder 7000 family ATM switch chassis, overriding any existing  
admin vLAN names.  
For this section and the Virtual Network Configuration section to operate  
correctly, at least one CoreBuilder 7X00 interface card must be installed in  
the CoreBuilder 7000 family ATM switch chassis.  
The following shows a typical LE Client Configuration section. Make a list

Additional Switch  
Configuration  
The Integrated Fast Setup configures a minimum set of network  
parameters - enough to get you started.  
If you need to make changes or to perform additional configuration  
tasks, use individual items of the LMA menus. These are all described in  
the CoreBuilder 7000 Family ATM Switches User Guide.  
Some additional configuration tasks might be:  
Configuring SVCs  
CoreBuilder 7000 family ATM switches use standard UNI 3.0 or 3.1  
switched virtual channel (SVC). SVC mode can be used when CoreBuilder  
is in a backbone or workgroup topology, with PVC used whenever  
necessary. ILMI enables automatic address registration for SVC. Addresses  
can be registered manually via the LMA menus  
Setting the Mode  
The CoreBuilder will run UNI 3.0 SVC by default. You can work in UNI 3.1  
by choosing this option in the signalling setup menu.  
Setting Network Prefix and ATM Addresses  
ATM addresses are essential for establishing a connection using SVC.  
Most devices that support SVC, also support automatic address  
registration through the ILMI protocol.  
A network prefix is essential for address registration to be executed. Refer  
to CoreBuilder 7000 Family ATM Switches User Guide for proper network  
prefix setting.  
For connectivity with devices that do not support ILMI, ATM addresses  
can be set manually using the Add ATM address function under ATM  
address setup in the Administration Console menus.  
Configuring a PVC  
Permanent Virtual Channels (PVC) can be used to connect to devices that  
do not support switched virtual channels (SVC) standard protocols. In the  
CoreBuilder 7000 family ATM switch you can create point-to-point (P2P)  
and point-to-multipoint (P2M) connections. Use the Setup and  
Configuration Connections menu, to create a PVC call, PTP or PTM. You  
can also create an out VC in a PTM call, release a PVC call, release an out

Configuration You can store (upload) the configuration of an installed card from its flash  
Upload/Download memory to an external disk and restore it (download) to the flash  
memory of the original card — or to the flash memory of a different card  
of the same type — at a later time. You can perform this operation only  
through the LMA and not via a SNMP management application like  
Transcend.  
When the switch operates in single-IP Mode, you can use this facility to  
upload the configuration of any of the installed cards through the LMA of  
the switch card. When the switch is operating in multiple-IP mode, you  
can use this facility to upload the configuration of the switch card only.  
This feature lets you:  
Backup your switch configuration in case of switch failure  
Transfer the configuration from one switch to another  
Maintain various standard configuration templates which can be  
loaded according to requirement  
The configuration upload works for individual cards installed in the  
CoreBuilder 7000: either the active switch card or a CoreBuilder 7X00  
Interface Card. You select the card whose configuration you want to  
download or upload from a list of installed cards.  
You cannot upload or download configuration parameters to a switch  
card while it is installed as a redundant switch card. You need to remove  
the card from the chassis, install it in a different switch chassis as the  
active switch card and then perform the upload/download operation, as

static_7600_1.  
When you download configuration data from the files on the disk to the  
card, you designate the card by its slot number. The slot can contain the  
original card from which the data was uploaded, or it can contain  
another card of the same type.  
If you try to download configuration data which was uploaded from one  
type of card type to another type of card, an appropriate error message is  
issued.

read from the flash memory. The CoreBuilder 7000 assumes that the user  
wants to reboot the switch as soon as possible to activate the new  
configuration parameters. Therefore, subsequent to a configuration  
download, all LMA and SNMP set operations are blocked until the next  
reboot – except for the configuration upload/download and reboot  
operations.  
It is recommended, therefore, to perform a configuration download only  
when you are ready to reboot and activate the new parameters.  
Cards should not be “hot swapped” after a configuration download until  
after the next reboot.

information on installing redundant devices, see Chapter 4.  
This chapter includes the following topics:

Supply  
This section discusses the following topics:  
Types of power supplies available  
Power requirements of the CoreBuilder 7000 family switching and  
interface cards  
Using redundant switching cards and redundant power supplies.  
Types of Power The CoreBuilder 7000 family supports three kinds of power supplies: an  
Supplies AC unit rated at 90A, and two DC units rated at 90A and 40A. You can  
use each one of them in any CoreBuilder 7000 family ATM switch. The  
power supply supports two output channels: one 5V DC channel which  
supplies the CoreBuilder switch and the interfaces cards, and one 12V DC  
channel which supplies the fans.  
The CoreBuilder 7000 family power supplies are shown in Table 7-1.

Power Supply Load Sharing  
Operation  
The power supplies can operate in load-sharing mode; two 90A power  
supplies can produce up to 180A. Providing that the power consumption  
of the unit does not exceed 90 A, load-sharing allows one power supply  
to serve as a backup.  
Overloading  
When the installed power supply is rated for less than the required power  
consumption of the CoreBuilder module, the CoreBuilder will not  
succeed in powering up. It will attempt to power up, hit the current  
overload rate and turn the power supply off, going through this cycle  
repeatedly until the load is reduced.  
Calculating the Power The power consumption of an entire CoreBuilder 7000 family ATM switch  
Consumption of unit is calculated by adding up the power consumption of the switching  
CoreBuilder Switch card(s) and interface cards installed in the chassis. Normally, the values for  
typical power consumption can be used in the calculation. Table 7-2  
shows the typical power consumption values for the CoreBuilder 7000  
family ATM switching cards and interface cards

Providing This section describes when redundant switch cards and redundant  
Redundancy for power supplies can be used in a CoreBuilder switch.  
Various Power Loads  
In order to determine whether a redundant switch card and/or an  
redundant power supply can be used in a CoreBuilder switch, the total  
power consumption of all installed cards must be examined. According to  
the total power consumption, there are three possibilities, as the  
following examples illustrate:  
Installation I: The total power consumption of a single switching card  
(that is, no redundant card installed) and all interface cards exceeds 90A.  
In this case, a Dual 90A supply is required so that the second power  
supply cannot be redundant. A redundant switch card can be installed.  
This “heavy load” installation is illustrated by the first example installation  
in Table 7-3.  
Installation II: The total power consumption of two switching cards  
(i.e., redundant card installed) and all interface cards exceeds 90A but  
without the second switching card the consumption is less than 90A. In  
this case, either a redundant switch card or a redundant power supply  
can be installed, but not both. This “medium load” installation is  
illustrated by the second example installation in Table 7-3.  
Installation III: The total power consumption of two switching cards  
and all interface cards does not exceed 90A. In this case, both a  
redundant switch card and a redundant power supply can be installed.

Redundant Power Supply 7-7  
The light load installation is illustrated by the fourth example installation  
in Table 7-3.  
In all installations that do not include multiple CB7600 cards both  
redundant switch cards and redundant power supplies can be installed.

Redundant Switching Module 7-9  
Redundant  
Switching Module  
This section covers the following topics:  
Need for a Redundant Switching Module  
Identifying the Active Switching Module  
Conditions for Switch-over to Redundant module  
Switching Module Configuration Database  
Info Based on the MAC Address  
Resetting to Factory Defaults  
A redundant switching module is a backup switching card that is capable  
of performing all the tasks of the currently active switching module  
should it fail. For this purpose, the redundant modules data base is kept  
up-to-date with network parameters that are configured in the active  
switching module.  
Need for a  
Redundant Switching  
Module  
The redundant switching module is a necessary requirement in a  
critical-mission network. When a switch module fails in such a network,  
loss of data and interruption in transmission must be kept to an absolute  
minimum.  
As the CoreBuilder 7000 boots, the first of the two switch modules to  
begin operating becomes the active switch module.  
Identifying the Active  
Switching Module  
Once the unit has booted, the active switch module can be identified by  
the LMA command (1) SYS (4) SWM: or by the ACT LED as follows:  
Active Switch: ACT LED flashes rapidly  
Redundant Switch: ACT LED flashes once every 2 secs.  
The redundancy feature works for any combination of the CoreBuilder  
7000 and CoreBuilder 7000HD switch modules installed in the chassis.  
The switch-over to the redundant module will occur in the following  
situations:  
Conditions for  
Switch-over to  
Redundant module  
Removal of the main switching module from the chassis.  
Malfunction of the main switching module.  
Manual reboot of the CoreBuilder 7000 by LMA, Telnet (soft reboot)  
or Transcend NMS.

CHAPTER 7: REDUNDANCY IN THE COREBUILDER 7000 FAMILY ATM SWITCH  
During the switch-over, the redundant switch reboots itself and comes up  
as the active one. A temporary dropping of all connections will occur  
during the switch-over. The connections are re-established after the  
switch-over process is complete.  
Each switching module contains a configuration data base where the  
switch configuration data is stored. In order that the redundant switching  
module be ready to assume the role of the active switch, its configuration  
database is updated from the active switch. This occurs in the following  
situations:  
Switching Module  
Configuration  
Database  
When the switch configuration is changed.  
Not all of the configuration data is transferred from the active to the  
redundant switch. The data that was not transferred must be updated  
manually. The following table presents data which is transferred and data  
which must be updated manually (see “Setting up Switch Module  
Hardware Redundancy” on page 4-7).

Each switching module board has a unique MAC address burned into its  
EPROM. This MAC address is used by the CoreBuilder 7000 for three  
purposes:  
Info Based on the  
MAC Address  
For the IP stack  
For the LES ATM address user part  
For calculating a unique number to be assigned to the ELAN name.  
xxxx  
The ELAN names have the format ELANxxxx_y where  
is a unique  
number calculated using the MAC address and y is an integer from 0 to  
15 automatically assigned to each of the 16 default LESs of the  
CoreBuilder 7000. In this way, each LES has a unique ELAN name and  
unique ATM address.  
When a redundant switching card takes over after the primary switching  
card fails, the IP address, the ELAN names and LES address remain the  
same as they were in the primary switch.  
Publishing the New MAC Address  
A redundant switch that has become active sends a reverse ARP (RARP) to  
publish its MAC address to the network devices.  
For devices that do not learn MAC addresses from a RARP, you will need  
to reset the IP address entry of the CoreBuilder 7000 in their device table.  
The ELAN names and LES addresses (user part) will be changed only if the  
user performs a reset to factory defaults by LMA (or TELNET).  
Resetting to Factory  
Defaults  
After resetting to factory defaults, the MAC address burned in the active  
switch EPROM will supersede the one stored in the FLASH memory  
resulting in new ELAN names and LES addresses.  
Resetting to factory default will cause all connections to be dropped until  
the new ELAN names are updated in the LECs.

Diagnostic Procedures  
Table 8-3  
Procedure  
Action  
Checking fan  
operations  
In case of system overheating, check that the power supply fan and the fans in the fan tray  
are operating. To check for fan movement in the CoreBuilder 7000 family ATM switch’s  
fan tray, pull a few modules from the chassis to view the fans on the left side of the  
system.  
Cleaning dirty fiber  
optic cables*  
Fiber optic transceivers are sensitive optical devices that need to be handled carefully. If dirt  
collects on the fiber optic lens, you may notice that the LED for an ATM port link status  
does not light. You may also notice degraded performance of that port, indicated by an  
increase in the physical layer statistics count for that port.  
To prevent dust from collecting on the fiber optic lens, keep the dust covers on the ports at  
all times when they are not in use. To clean a fiber optic lens, follow the procedure below:  
1 Remove any accumulated dust or debris from the port or connector by blowing off all  
surfaces with a canned air duster.  
2 Compressed gas is recommended, such as Chemtronics’ Ultrajet ® or the Triangle Tool  
Group’s Liqui-Too!™ Dust-A-Way. Do not use commercial compressed air or “house  
air” because of the risk of oil contamination.  
3 Reconnect the cable to the port to see if the dusting corrected the problem.  
4 If the LED still does not appear, or if it lights yellow, continue with steps 5 and 6.  
5 Gently wipe the ports with a lint-free, non-abrasive, non-adhesive swab. Microswabs™  
by Texwipe™ are recommended.  
6 Gently wipe the connectors with a lint-free, non-abrasive wipe or pad. Texwipe™ pads  
are recommended.  
* See safety precautions in next section.  
Safety Precautions for Fiber Optics Connectors  
Avoid touching all surfaces after cleaning the connectors, and keep all  
unused ports covered.  
Vermeiden Sie das Berühren aller Oberflächen nach dem Säubern der  
Kontakte und verdecken Sie alle nicht benutzten Öffnungen.  
Ne toucher aucune surface après le nettoyage des connecteurs et garder  
les pièces inutilisées couvertes.

CABLING REQUIREMENTS  
E
This chapter addresses many aspects of installing optical fiber cabling to  
support the CoreBuilder 7000 family ATM switch environment. It will also  
deal with modem cables and Ethernet and control cables for  
management. The following topics are covered:  
Installing new cabling  
ATM cabling requirements  
Ethernet cabling requirements  
Installing New  
Cabling  
If you are installing new cabling, follow these guidelines:  
3Com recommends that you use a cabling system plan, such as  
AT&T's Premises Distribution System (PDS) or the IBM Cabling System.  
Determine how many CoreBuilder 7000 units are going to be  
supported by each wiring closet, and how many downlink  
connections from these CoreBuilder 7000 units are planned.  
Locate wiring closets to enable connections to the different floors.  
To simplify installation of the network and to aid in troubleshooting,  
install a telephone in each wiring closet for communication between  
wiring closets, work areas, and other locations.  
Include all linear distances (vertical rises, etc.) in the cable plan so that  
all cables - from wiring closet to desk and to other wiring closets - are  
under their respective maximum lengths.  
A reliable cable labelling and record keeping system is essential when  
planning any network installation. A good cable labelling system provides  
enough information for you to locate the opposite end of any cable.  
Maintaining accurate records helps you to: 1) relocate devices easily,  
2) make changes quickly, and 3) isolate faults in the distribution system.

E-2  
APPENDIX E: CABLING REQUIREMENTS  
Consult the cabling system plan to set up the cable labeling and record  
keeping system best suited to the environment. Also consider the  
following recommendations:  
Identify cables by securely attaching a label to the ends of all cables.  
Draw a floor location grid matrix using the building floor plans. For  
easy reference, use this grid when assigning location numbers to  
cables.  
Assign a unique block of sequential numbers to the group of cables  
that run between each pair of wiring closets.  
Assign a unique identification number to each distribution rack.  
Make all work areas and wiring closets easy to identify by labeling the  
front panel of the CoreBuilder 7000 and other hardware and by  
displaying the floor location grid and cabling plan in each wiring  
closet.  
Keep accurate and up-to-date cable identification records, such as  
IBM's Cable Identification Label Sheet or Cable Schedule. Post records  
near each distribution rack. On the appropriate cable schedule, record  
the following cable drop information: the cable source, destination,  
jumper location, and any additional information.  
Make sure that optical and coax cables are labeled Rx and Tx  
accordingly.

ATM Cabling  
E-3  
ATM Cabling  
When planning the installation, thoroughly inspect the present cabling to  
determine if it meets the specifications in the cabling system or standards  
used at the site.  
In addition to adhering to the local standards, all cable must conform to  
the American National Standard ATM Physical Layer Medium Dependent  
(PMD) standard, ISO.166-1990, American National Standards Institute,  
which defines the Physical Medium Dependent (PMD) layer of the ATM  
network. Currently, there are two approved PMD standards: Multi-mode  
Fiber (MMF-PMD), which is defined in ANSI standard X.3-166-1992, and  
Single Mode Fiber (SMF-PMD), which is defined in ANSI standard  
x.3-184-198x.  
3Com supports multi-mode fiber (MMF-PMD) 62.5/125 µm and Category  
one (1) single mode fiber (short reach) (SMF-PMD). When deciding  
whether to use multi-mode or single mode fiber, determine the maximum  
interstation distance (the distance from the CoreBuilder 7000 to any  
potential end station):  
If the maximum interstation distance is less than or equal to 2  
kilometers (1.25 miles), use multi-mode fiber (MMF-PMD).  
If the maximum interstation distance is greater than 2 kilometers (1.25  
miles) and less than or equal to 14.4 kilometers (8.6 miles), use single  
mode fiber (short reach) (SMF-PMD).  
Fiber optic transceivers are sensitive optical devices that need careful  
handling. The following information offers suggestions about caring for  
fiber optic cable.  
Caring for Fiber Optic  
Transceivers  
Dirt on the Fiber Optic Lens  
If dirt collects on the fiber optic lens, you may notice that the LED for an  
ATM port either does not light or lights yellow. You may also notice  
degraded performance of that port, as indicated by a decrease in the Link  
Error Rate (LER) estimate for that port.  
To prevent dust from collecting on the fiber optic lens, keep the dust  
covers on the ports at all times when they are not in use. To clean a fiber  
optic lens when it becomes dirty, see the section “Cleaning Dirty Fiber  
Optic Cables”.

APPENDIX E: CABLING REQUIREMENTS  
Damaged Transceiver Due to Excessive Insertion Force  
The ATM specification for insertion force on the connector into an ATM  
SC receptacle is 3.5 lbs. However, it is possible to exert up to 30 lbs. of  
insertion force on the transceiver if you are too forceful while inserting  
the SC connector into the receptacle. This can cause failure of the  
transceiver's mechanical joints, permanently damaging the part and  
disabling the port.  
When inserting connectors into the ATM ports, gently insert the SC  
connector into the receptacle until you hear the connector click into  
place. Use only enough force to engage the connector in the receptacle -  
no more than 3.5 lbs. This will avoid damage to the transceiver.  
The MMF-PMD standards define the requirements for an ATM cable plant  
to support an interstation distance of up to 2 kilometers (1.25 miles) of  
multi-mode fiber. The cable plant includes all fiber optic components  
between any two communicating ATM devices and their associated  
“station-to-network” connectors at each end.  
Multi-mode Fiber  
Standards  
To determine whether the cable plant complies with the MMF-PMD  
standard, do the following:  
Compare the specifications of the fiber you are using to standard  
specifications, as described in Table E-1 and Table E-2.  
1
2
If unlike fibers are mated in the cable plant, calculate insertion losses to  
see whether they exceed the maximum attenuation value allowed for a  
link, as described in Table E-3 and Table E-4.  
Verify that the fiber's modal bandwidth is within an acceptable range for  
the length of the link, as described on page E-7.  
3
The following sections describe each of these steps and give examples.  
Comparing Fiber to Specifications  
Compare the specifications of the fiber you are using to those in the  
following tables. If the fiber does not meet the specifications, use a  
different fiber or contact 3Com's Technical Support.  
The fiber you use must meet the specifications listed in Table E-1, which  
describes the standard set forth in MMF-PMD. Table E-2 describes  
62.5/125 cable, commonly sold as “ATM Spec,” which meets all the  
requirements of the MMF-PMD standard.

If unlike fibers are mated in the cable plant, calculate insertion losses to  
be certain that the cable plant does not exceed the maximum attenuation  
value listed in Table E-1. To calculate the insertion loss, consider the types  
of fiber in the cable plant and the connectors or splices used to join them.  
Compare the result to the maximum attenuation value listed in Table E-1.  
If the result is greater than the value in the table, use only like fibers in the  
cable plant.

* for mating unlike fiber types  
Because the resulting value, 7.85, does not exceed the maximum  
attenuation value listed in Table E-1, no adjustments are needed in the  
types of fibers joined or how they are connected. The link meets all of the  
specifications of the MMF-PMD.  
The bandwidth of an optical fiber is the lowest frequency where the  
magnitude of the baseband frequency response has decreased by 3 dB  
compared to the magnitude at zero frequency. Bandwidth for multi-mode  
fiber is referred to as modal bandwidth because it varies based on the  
modal field (or core diameter) of the fiber. Modal bandwidth is specified  
in units of MHz km, which indicates the amount of bandwidth  
supported by the fiber for a one km distance.  
Verifying Modal  
Bandwidth  
The modal bandwidth specified in Table E-1 is 500 MHz km, which  
allows the cable plant to support end-to-end bandwidth of 250 MHz at  
the maximum 2 km distance. As a check, use the following formula to  
verify that the bandwidth of the fiber is within an acceptable range:  
n MHz km / xkm = y MHz  
In this formula, n is the amount of bandwidth available according to the  
fiber specification. Divide this number by the total length x of the fiber in  
kilometers. The result is the modal bandwidth y, measured in MHz.  
If the result is lower than 250 MHz, the link may increase bit errors. To  
reduce the likelihood of bit errors, shorten the length of the fiber or use  
different fiber until the result of the calculation reaches 250 MHz.  
km will have 250  
Example. Cable with a modal bandwidth of 500 MHz  
MHz of bandwidth at 2 km:

E-8  
APPENDIX E: CABLING REQUIREMENTS  
(500 MHz km) / 2 km = 250 MHz  
The same cable would have 500 MHz of bandwidth at 1 km. A fiber cable  
with a bandwidth specification of 200 MHz km would have only 100  
MHz of bandwidth at 2 km, which would not support ATM. In this case,  
another type of fiber would be required.  
The SMF-PMD standard defines the requirements for an ATM cable plant  
to support a connection distance of up to 14.4 kilometers (8.6 miles) of  
single mode fiber. The cable plant includes all fiber optic components  
between any two communicating ATM devices and their connectors at  
each end.  
Single Mode Fiber  
Standards  
To determine whether the cable plant complies with the SMF-PMD  
standard, do the following:  
Compare the specifications of the fiber you are using to standard  
specifications, as described in Table E-6.  
1
2
If you mix equipment supporting Category 1 and Category 2, verify the  
maximum attenuation between the equipment, as described in Table E-7.  
The following pages describe each of these steps and give examples.  
Compare the specifications of the fiber you are using to those in  
Table E-6. If the fiber does not meet the specifications, use a different  
fiber or contact 3Com Technical Support.  
Comparing Fiber to  
Specifications  
The single mode PMD specification (SMF-PMD) defines two optical power  
categories: Category 1 and Category 2. These categories refer to the  
optical power that must be launched into the fiber by the transmitter or  
detected by the receiver. 3Com currently supports only Category 1 single  
mode fiber.  
The specifications for the standard single mode fiber are listed in  
Table E-6. Refer to the Category 1 specifications in this table for fiber  
connecting 3Com equipment. For fiber used with Category 2 equipment  
from another vendor, refer to the Category 2 specifications.  
The cable plant for a Category 2 implementation must have a minimum  
loss of 15.0 dB. In a Category 2 implementation, minimum cable plant  
losses are required to avoid saturating (blinding) the receiver.

*This combination is dispersion-limited rather than loss-limited. The  
expected maximum length is approximately 35 km.  
Example. If a Category 2 transmitter is outputting to a Category 1  
receiver, the maximum attenuation is 26.0.  
Connect the CoreBuilder 7000 DS-3 interface by a 75 Ohm coaxial cable  
that complies with DS-3 standards. The maximum cable length is 450  
feet. To connect the DS-3 interface:  
DS-3 Coax Cables  
Prepare two coax cables - one for Tx and one for Rx. You may want to  
mark the ends of the cables to identify them easily.

Connect both cables to the DS-3 BNC connectors on the CoreBuilder  
interface. Make sure to connect Rx and Tx cables according to what is  
indicated on the interface front panel.  
Connect the two cables at the other end according to the opposite of the  
first connection Rx to Tx and Tx to Rx.

Ethernet Cabling E-11  
Ethernet Cabling  
The Ethernet port of the CoreBuilder allows you to connect the  
CoreBuilder to an Ethernet network for Network Management Station  
(NMS) connectivity (such as Transcend™). The Ethernet port is a standard  
RJ-45 connection of a terminal side.  
Follow these guidelines for 10BASE-T cabling:  
Use only copper, unshielded twisted-pair (UTP) wiring. Do not use flat,  
multiconductor cable (for example, silver satin), which is often  
identified by solid colors such as red, green, yellow, or black.  
Use two twisted-pairs for each link.  
Use twisted-pair wire that is 22-26 AWG (0.5 millimeter) in diameter.  
Use twisted-pair wire with an impedance between 85 and 115 ohms.  
Make sure that the maximum twisted-pair link length from the system  
to any potential workstation location is 100 meters (328 feet).  
Management connections may be established with a direct cable link to a  
PC-AT serial port, or via modem. The following tables detail cable pinouts  
for 9 and 25 pin PC-AT links, and for a modem connection.  
Cable Pinouts  
CoreBuilder 7000 Serial Port  
The CoreBuilder 7000 provides a standard DB-9 connector for  
management connections (refer to Figure E-1). Table E-8 details the  
pinout and functions for this connector. The CoreBuilder 7000 plays the  
standard role of a DCE.
