SAFETY INFORMATION  
CLASS 1 LASER TRANSCEIVERS  
THE DELF3-UI FAST ETHERNET INTERFACE MODULE, DEL05-UI  
FDDI PORT INTERFACE MODULE, AND DEL29-UI ATM PORT INTER-  
FACE MODULE USE CLASS 1 LASER TRANSCEIVERS. READ THE  
FOLLOWING SAFETY INFORMATION BEFORE  
INSTALLING OR OPERATING THESE MODULES.  
The Class 1 laser transceivers use an optical feedback loop to maintain Class 1 operation limits. This  
control loop eliminates the need for maintenance checks or adjustments. The output is factory set, and  
does not allow any user adjustment. Class 1 laser transceivers comply with the following safety  
standards:  
21 CFR 1040.10 and 1040.11 U.S. Department of Health and Human Services (FDA).  
IEC Publication 825 (International Electrotechnical Commission).  
CENELEC EN 60825 (European Committee for Electrotechnical Standardization).  
When operating within their performance limitations, laser transceiver output meets the Class 1  
accessible emission limit of all three standards. Class 1 levels of laser radiation are not considered  
hazardous.  
SAFETY INFORMATION  
CLASS 1 LASER TRANSCEIVERS  
LASER RADIATION AND CONNECTORS  
When the connector is in place, all laser radiation remains within the fiber. The maximum amount of  
radiant power exiting the fiber (under normal conditions) is -12.6 dBm or 55 x 10-6 watts.  
Removing the optical connector from the transceiver allows laser radiation to emit directly from the  
optical port. The maximum radiance from the optical port (under worst case conditions) is  
0.8 W cm-2 or 8 x 103 W m2 sr-1.  
Do not use optical instruments to view the laser output. The use of optical instruments to view  
laser output increases eye hazard. When viewing the output optical port, power must be  
removed from the network adapter.

Safety  
CAUTION  
An odd number of crossovers (preferably one)  
must be maintained between devices so that  
the transmit port of one device is connected to  
the receive port of the other device and vice  
versa.  
If the fiber optic cable being used has SC style  
connectors that do not resemble MIC style  
connectors, or has SC connectors on one end  
and a different type on the other, such as ST  
connectors, ensure that the proper crossing  
over occurs.  
ACHTUNG  
Eine ungerade Zahl von Überkreuzungsstellen  
(vorzugsweise eine) muß zwischen den  
Geräten beibehalten werden, damit der  
Übertragungsanschluß eines Gerätes mit dem  
Empfangsanschluß des anderen Gerätes  
verbunden werden kann (und umgekehrt).  
Wenn das verwendete Glasfaserkabel  
SC-Anschlußstecker hat, die nicht  
MIC-Anschlußsteckern ähnlich sind, oder  
wenn es an einem Ende SC-Anschlußstecker  
hat und am anderen Ende einen anderen  
Steckertyp (z.B. einen ST-Stecker),  
vergewissern Sie sich, daß die richtig  
Überkreuzung stattfindet.  
ATTENTION  
Un nombre impair de diagonales (de  
préférence une) doit être conservé entre les  
périphériques de sorte que le port de  
transmission d'un périphérique soit connecté  
au port de réception de l'autre périphérique et  
inversement.

CHAPTER 1  
INTRODUCTION  
This chapter describes the features of the DLE2X-MA and DLE3X-MA  
Interface Modules.  
1.1  
DLE2X-MA AND DLE3X-MA OVERVIEW  
The DLE2X-MA and DLE3X-MA, shown in Figure 1-1, are interface  
modules for the DLM6C-AA chassis.  
The DLE2X-MA and DLE3X-MA are high-speed network switch  
devices that support 802.1D switching (bridging) and 802.1Q switching.  
Ports 25 and 26 of the DLE2X-MA support optional Fast Ethernet  
Interface Modules and can provide uplinks to 100BASE-TX or  
100BASE-FX Fast Ethernet networks. The DLE3X-MA is capable of  
being equipped with a High Speed Interface Module (HSIM) that  
provides for additional connectivity to other high speed networking  
technologies such as Asychronous Transfer Mode (ATM), Wide Area  
Networks (WANs) and Fiber Distributed Data Interface (FDDI).  
The DLM6C-AA can be used to connect individual high-bandwidth user  
devices, such as workstations, and to provide a central switching point for  
multiple Ethernet segments using devices such as the HubSTACK or  
other third party stackable devices.  
Figure 1-1 displays the DLE22-MA and DLE32-MA. The  
DLE22-MA and the DLE23-MA are functionally identical, as are  
the DLE32-MA and the DLE33-MA. The only difference being  
that the DLE23-MA and DLE33-MA modules support RJ21  
front panel connections.

The DLE2X-MA and DLE3X-MA provide 802.1D switching and 802.1Q  
switching between all of the front panel interfaces including Fast Ethernet  
Interface Modules and High Speed Interface Modules (HSIMs).  
The 802.1Q switching option allows for future migration to Virtual  
Network technologies without requiring the replacement of existing  
equipment.  
1.1.6  
Standards Compatibility  
The DLE2X-MA and DLE3X-MA are fully compliant with the IEEE  
802.3 standard. The optional Fast Ethernet Interface Modules are fully  
compliant with the IEEE 802.3u standard. The DLE2X-MA and  
DLE3X-MA provide IEEE 802.1D Spanning Tree Algorithm (STA)  
support to enhance the overall reliability of the network and protect  
against “loop” conditions. The DLE2X-MA and DLE3X-MA support a  
wide variety of industry standard MIBs including RFC 1213 (MIB II),  
RFC 1757 (RMON), RFC 1493 (Bridge MIB) and RFC 1354 (FIB MIB).  
A full suite of the Enterprise MIBs provide a wide array of statistical  
information to enhance troubleshooting.  
1.1.7  
LANVIEW Diagnostic LEDs

DLE2X-MA and DLE3X-MA Overview  
1.1.8  
Year 2000 Compliant  
The DLE2X-MA and DLE3X-MA have an internal clock that can  
maintain the current time and date beyond the year 1999.  
1.1.9  
Runtime IP Address Discovery  
This feature enables the modules to automatically accept an IP address  
from a BootP server on the network into NVRAM without requiring a  
user to enter an IP address through Local Management.  
When the modules are connected to the network and powered up,  
Runtime IP Address Discovery (RAD) checks the modules for an IP  
address. If one has not yet been assigned (module and DLM6C-AA  
chassis IP address set to 0.0.0.0), RAD checks to see if any of the module  
interfaces have a link. If so, RAD sends out Reverse Address Resolution  
Protocol (RARP) and BootP requests to obtain an IP address from a  
RARP or BootP server on the network.  
The RAD requests start out at an interval of one second. The interval then  
doubles after every transmission until an interval of 300 seconds is  
reached. At this point, the interval remains at 300 seconds. The RAD  
requests continue until an IP address is received from a RARP or BootP  
server, or an IP address is entered using Local Management.  
1.1.10 Local Management Features  
Local Management provides the tools that allow management of the  
DLE2X-MA and DLE3X-MA, the Fast Ethernet Interface Modules, the  
High Speed Interface Module (HSIM) and the DLM6C-AA chassis. It  
also allows the following tasks to be performed:  
Manage any module installed in the DLM6C-AA via a single terminal  
connection.  
Assign an IP address and subnet mask to the DLM6C-AA chassis,  
DLE2X-MA and DLE3X-MA.  
Select a default gateway.  
Control local and remote access.

Figure 3-7). Cabletron Systems supplies fiber optic cable that uses SC  
style connectors that are keyed to ensure proper crossing over of the  
transmit and receive fibers.  
An odd number of crossovers (preferably one) must be  
maintained between devices so that the transmit port of one  
device is connected to the receive port of the other device and  
vice versa.  
!
If the fiber optic cable being used has SC style connectors that  
do not resemble MIC style connectors, or has SC connectors  
on one end and a different type on the other, such as ST  
connectors, ensure that the proper crossing over occurs.  
Fiber Optic Network Connection  
1. Remove the protective plastic covers from the fiber optic ports on the  
applicable port on the module and from the ends of the connectors.  
The DELF3-UI uses Class 1 lasers. Do not use optical  
instruments to view the laser output. The use of optical  
instruments to view laser output increases eye hazard. When  
viewing the output optical port, power must be removed from  
the network adapter.  
Do not touch the ends of the fiber optic strands, and do not let  
the ends come in contact with dust, dirt, or other contaminants.  
!
Contamination of the ends causes problems in data  
transmissions. If the ends become contaminated, clean them  
with alcohol using a soft, clean, lint-free cloth.  
2. Insert one end of the SC connector into the DELFX-UI or DELF3-UI  
installed in the DLE2X-MA. See Figure 3-7.  
3. At the other end of the fiber optic cable, attach the SC connector to the  
other device.

Accessing Local Management  
5.3.4  
Telnet Connections  
Once the module or chassis has a valid IP address, the user can establish a  
Telnet session with Local Management from any TCP/IP based node on  
the network. Telnet connections to the DLE2X-MA and DLE3X-MA  
require the community name passwords assigned at the SNMP  
Community Names screen of either the DLM6C-AA chassis, or the  
module. For additional information about community names, refer to  
Section 5.8, SNMP Community Names Screen. Refer to the instructions  
included with the Telnet application for information about establishing a  
Telnet session.  
5.4  
ACCESSING LOCAL MANAGEMENT  
Access to Local Management is controlled through the Password screen,  
Figure 5-3. Whenever a connection is made to the DLE2X-MA and  
DLE3X-MA the Password screen displays. Before continuing, the user  
must enter a password which is compared to the previously stored  
passwords. The level of access allowed the user depends on the password.  
To set or change passwords refer to Section 5.8. The following steps  
describe the procedure to access Local Management.  
1. Turn on the terminal. Press ENTER (this may take up to four times,  
because the COM port of the DLE2X-MA and DLE3X-MA  
auto-senses the baud rate of the terminal) until the DLM6C-AA Local  
Management Password screen, Figure 5-3, displays.

(Modifiable)  
IP Address  
This field allows the IP address to be set for the DLM6C-AA chassis. If  
an IP address is assigned to the DLM6C-AA chassis all the interface  
modules installed in the chassis can be managed via this IP address,  
eliminating the need to assign an IP address to each interface module. To

Chapter 5: Local Management  
Subnet Mask (Modifiable)  
When a valid IP address is assigned, the Subnet Mask field  
automatically enters the default mask that corresponds with  
class of IP entered in the IP Address field. Some firmware  
revisions do support changing the chassis subnet mask from  
the default value. Refer to your Release Notes to ensure that  
the Subnet Mask is a modifiable field.  
Displays the subnet mask for the chassis. A subnet mask “masks out” the  
network bits of the IP address by setting the bits in the mask to 1 when the  
network treats the corresponding bits in the IP address as part of the  
network or subnetwork address, or to 0 if the corresponding bit identifies  
the host. The DLM6C-AA chassis automatically uses the default subnet  
mask that corresponds to the IP class that was entered in the IP address  
field. Section 5.7.2, Setting the Subnet Mask describes how to change the  
subnet mask from the default value.  
Chassis Date (Modifiable)  
Contains a value that the chassis recognizes as the current date. When the  
chassis date is modified and saved all interface modules installed in the  
chassis are set to this date. To set a new chassis date, refer to  
Section 5.7.3.  
Chassis Time (Modifiable)  
Contains a value that the chassis recognizes as the current time. When the  
chassis time is modified and saved, all interface modules installed in the  
chassis are set to this time. To enter a new time, refer to Section 5.7.4.  
Screen Refresh Time (Modifiable)  
Contains the rate at which the screens are updated. This setting  
determines how frequently (in seconds) information is updated on the  
screen. To enter a new update time, refer to Section 5.7.5.  
Screen Lockout Time (Modifiable)  
Contains the maximum number of minutes that the Local Management  
application displays a module’s screen while awaiting input or action  
from a user. For example, if the number 5 is entered in this field, the user  
has up to five minutes to respond to each of the specified module’s Local  
Management screens. In this example, after five minutes of “idleness” (no  
input or action), the terminal “beeps” five times, the Local Management

application terminates the session, and the display returns to the Password  
screen. To enter a new lockout time, refer to Section 5.7.6.  
Chassis Uptime (Read-Only)  
Displays the total time the chassis has been operating. The chassis uptime  
is based on which interface module installed in the chassis has been  
operating for the longest period of time.  
Operational Mode (Toggle)  
This field allows the user to set all the modules in the chassis to operate as  
traditional switches (802.1D SWITCHING option), or as IEEE 802.1Q  
switches (802.1Q SWITCHING option).  
In 802.1D SWITCHING mode, the 24 ports located on the front panel,  
and each Fast Ethernet Interface Module, and HSIM port(s) are bridged to  
each other.  
When the operational mode is set to 802.1Q SWITCHING, the  
DLE2X-MA and DLE3X-MA act as IEEE 802.1Q switches. The modules  
are able to increase their switching functionality by creating and  
maintaining port based Virtual LANs (VLANs).  
For details on how to select the Operational Mode, refer to Section 5.7.7.

5.11 PORT REDIRECT FUNCTION SCREEN  
The Port Redirect Function screen may not be available  
depending on the operational mode that has been set for the  
chassis. Refer to your Release Notes to see what operational  
modes support the Port Redirect Function. Refer to  
Section 5.7.7, Setting the Operational Mode, for instructions  
on configuring the operational mode of all the modules installed  
in the chassis.  
The Port Redirect Function screen, Figure 5-13, allows the user to set  
each one of the modules in the chassis (1 through 5), and the ports of the  
corresponding module installed, as a source or destination port. A port  
can be set to have one or more destination ports and chassis module slot  
numbers. For example, port 1 in module (slot) 1 can be set as a source  
port with three destinations, ports 2, 3, and 4 in module (slot) 3. Traffic  
from port 1 in module 1 is then automatically redirected to ports 2, 3, and  
4 in module 3. Port 1 in module 1 can also serve as a destination port for  
other ports and modules. The port redirect function is extremely useful for  
troubleshooting purposes, as it allows traffic to be sent to a particular  
port(s) where, with the use of an analyzer or RMON probe, all current  
traffic from the source port(s) can be examined.  
The module number corresponds to the slot number in which  
the module resides in the DLM6C-AA chassis (1 through 5).  
Although traffic from the source port (including, if desired,  
errored frames) is sent to the destination port, normal switching  
is still performed for all frames on the source port.  
Access the Port Redirect Function screen from the Chassis Menu screen  
by using the arrow keys to highlight the PORT REDIRECT  
FUNCTION menu item and pressing ENTER. The Port Redirect  
Function screen, Figure 5-13, displays.

refer to Section 5.15.11.  
Clear NVRAM (Toggle)  
This allows the user to reset NVRAM to the factory default settings. All  
user-entered parameters, such as IP address and Community Names are  
then replaced with DLE2X-MA and DLE3X-MA default configuration  
settings. For details, refer to Section 5.15.13.  
IP Fragmentation (Toggle)  
This field allows the user to enable or disable IP fragmentation. The  
default setting for this field is ENABLED. If the DLE2X-MA or  
DLE3X-MA will be bridged to an FDDI ring, IP Fragmentation should be  
enabled. If IP Fragmentation is disabled, all FDDI frames that exceed the  
maximum Ethernet frame size will be discarded. For details on enabling

5.16 SNMP COMMUNITY NAMES SCREEN  
The SNMP Community Names menu item allows the user to set  
Local/Remote Management community names. Community names act as  
passwords to Local/Remote Management and are agents of security  
access to the DLE2X-MA and DLE3X-MA. Access to the DLE2X-MA  
and DLE3X-MA is controlled by enacting any of three different levels of  
security authorization (read-only, read-write, and super-user).  
If the DLM6C-AA has been assigned community names, it is  
not necessary to assign community names to the individual  
modules installed in the chassis unless the user wishes to limit  
access to DLM6C-AA chassis screens by assigning different  
community names to the module. When this is done access is  
limited to the screens specific to the module to which the  
terminal is attached and the Local Management session begins  
at the Module Menu screen.  
Super-User access gives the user full management privileges,  
allows existing passwords to be changed, and all modifiable  
MIB objects for the Cabletron Container MIB and Internet  
MIB-II to be accessed.

Community Names screen. Using a password with read-only or  
read-write access does not allow the user to view or edit the SNMP  
Community Names screen.  
Any community name assigned in the SNMP Community  
Names screen is a password to its corresponding level of  
access to Local/Remote Management. The community name  
assigned Super-User access is the only one that gives the user  
complete access to Local/Remote Management.

5.20 SmartTrunk AND THE CONFIGURATION SCREEN  
Before discussing the SmartTrunk Configuration screen and how to use it,  
it is necessary to understand what SmartTrunk is and the port connection  
and configuration rules that must be followed. Failure to follow these  
rules will produce poor network performance. Refer to Appendix D,  
About SmartTrunk, for basic information on SmartTrunking. For  
SmartTrunk configuration rules, proceed to Section 5.20.1.  
5.20.1 SmartTrunk Configuration Rules  
The following rules must be followed when installing the DLE2X-MA  
and DLE3X-MA to operate in a network configuration using  
SmartTrunking. These rules also apply to other devices that support  
Cabletron Systems’ SmartTrunk application.  
1. Only ports designated as NETWORK ports, through Local or Remote  
Management screens, will be considered for SmartTrunking.  
2. All non-SmartTrunking interfaces MUST be designated as USER  
ports.  
3. A maximum of 12 ports may be used per instance, and there may only  
be 8 instances per device.  
4. If three or more devices are connected together for SmartTrunking,  
then the ports that connect any of the two devices together MUST be  
designated as USER ports to prevent a network loop condition. The  
port with the least amount of bandwidth available would be the port(s)  
that should be designated a “USER” port.  
5. You cannot loop front panel ports back to the same standalone device.  
If the devices are modules residing in a chassis, then you cannot loop  
back to the same module in the same chassis or to different modules  
within that chassis. This includes all backplane interfaces that may  
display on the SmartTrunk Configuration screen.  
DLE22-MA,DLE32-MA,DLE23-MA and DLE33-MA Users Guide 5-63  
Download from Www.Somanuals.com. All Manuals Search And Download.  
   
Chapter 5: Local Management  
6. You must enable Spanning Tree before enabling SmartTrunk.  
Spanning Tree will ‘block’ any ports not used by SmartTrunk that are  
looped. This can include NETWORK and USER ports. The reason  
for the blocking of a NETWORK port is that the port at the other end  
of the link may be configured as a USER port.  
Other Considerations  
If a network loop exists and SmartTrunk becomes disabled, and  
Spanning Tree is operational, then the Spanning Tree Algorithm will  
respond and block the necessary ports.  
If SmartTrunk becomes disabled, and a network loop exists, and  
Spanning Tree is not-operational (disabled), then an infinite packet  
loop would occur, taking down the network.  
If a port is disabled and as a result SmartTrunk is no longer active, then  
all traffic is redirected over the remaining port(s).  
If three or more interface modules, such as the DLE2X-MA and  
DLE3X-MA, or standalone devices are connected together in a loop  
condition and all the ports that connect the loop are set to  
NETWORK,” the results are unpredictable. In this case all ports are  
assigned as “NETWORK” ports and none are configured as “USER”  
ports. This is deemed an illegal configuration.  
If a network loop exists when a port is disabled, then SmartTrunk will  
reconfigure the remaining ports and continue to distribute traffic.  
5.20.2 SmartTrunk Configuration Screen  
The SmartTrunk Configuration screen may not be available if  
the operational mode of the module has been set to 802.1Q  
SWITCHING. Refer to your Release Notes to see if the  
SmartTrunking feature is supported.  
Section 5.15.9 describes how to set the operational mode.  
The SmartTrunk Configuration screen, Figure 5-25, allows the user to  
logically group interfaces together between devices to achieve greater  
bandwidth between the devices.  
Access the SmartTrunk Configuration screen from the Module Specific  
Configuration Menu screen by using the arrow keys to highlight the

SmartTrunk and the Configuration Screen  
SMARTTRUNK CONFIGURATION menu item and pressing ENTER.  
The SmartTrunk Configuration screen displays.  
Interfaces with the Port Name “Backplane” may display on this  
screen. These ports may not be used for SmartTrunking. Poor  
network performance will result if backplane ports are used as  
SmartTrunk interfaces. Section 5.20.1 details all SmartTrunk  
configuration rules.  
The DLE2X-MA and DLE3X-MA ports must be connected to a  
product that supports SmartTrunking for load sharing to  
function.

of the segment without requiring user setup. However, Local  
Management provides the user with the option of manually  
configuring that port.  
If an DELTX-UI is installed, the field steps to Auto-Negotiation,  
10BASE-T, 10BASE-TFD (full duplex), 100BASE-TX, and  
100BASE-TXFD (full duplex). In normal operation, the port with an  
DELTX-UI installed is capable of auto-negotiating the operational mode  
and no further user setup is required. Section 5.23.3 describes how to  
configure an DELTX-UI.  
Advertised Ability (Selectable)  
During auto-negotiation, the DELTX-UI “tells” the device at the other end  
of the segment what its capabilities are. The capabilities of a port (25 or  
26) with an DELTX-UI installed are 10BASE-T, 10BASE-TFD (full  
duplex mode), 100BASE-TX and 100BASE-TXFD (full duplex mode). In  
normal operation, with all capabilities enabled, the DELTX-UI  
“advertises” that it has the ability to operate in any mode. The Network  
Manager may choose to set up the port so that only a portion of the  
available capabilities are advertised and the others are disabled. For  
example, only 100BASE-TX and 100BASE-TXFD might be enabled so

that only devices that operate at 100 Mbps can communicate with that  
port. Section 5.23.5 describes how to enable or disable advertised modes.  
5.23.1 Configuring an DELFX-UI or DELF3-UI  
in Port 25 or 26  
When an DELFX-UI or DELF3-UI is installed in port 25 or 26, it must be  
manually set to operate in the same technology as the device at the other  
end of the connected segment. Section 5.23.2 provides instructions for  
manually configuring the port with an DELFX-UI or DELF3-UI  
interface.  
5.23.2 Setting the DELFX-UI and DELF3-UI  
Operational Mode  
Use this field to set the active technology. This field toggles between  
100BASE-FX and 100BASE-FXFD (full duplex). To set the active  
technology through Local Management, proceed as follows:  
1. Use the arrow keys to highlight the Desired Oper. Mode field.  
2. Use the SPACE bar to select 100Base-FX or 100Base-FXFD (full  
duplex).  
3. Press ENTER. The port now operates in the chosen mode.  
4. Use the arrow keys to highlight the SAVE command. Press ENTER.  
The message “SAVED OK” displays and Local Management saves  
the changes to memory.  
5.23.3 Configuring an DELTX-UI in Port 25 or 26  
In normal operation, a port (25 or 26) with an DELTX-UI interface  
automatically establishes a link with the device at the other end of the  
segment and no user setup is required. Section 5.23.4 and Section 5.23.5  
provide instructions for manually configuring the port with an DELTX-UI  
installed.  
5.23.4 Setting the DELTX-UI Operational Mode

5.25 PORT REDIRECT FUNCTION SCREEN  
The Port Redirect Function screen may not be available  
depending on the operational mode that has been set for the  
module. Refer to your Release Notes to see what operational  
modes support the Port Redirect Function. Refer to  
Section 5.15.9, Setting the Operational Mode, for instructions  
on configuring the operational mode of the module.  
The Port Redirect Function screen, Figure 5-30, allows the user to set  
each one of the ports on the DLE2X-MA and DLE3X-MA as a source or  
destination port. A port can be set to have one or more destination ports.  
For example, port 1 can be set as a source port with three destinations,  
ports 2, 3, and 4. Traffic from port 1 is then automatically redirected to  
ports 2, 3, and 4. Port 1 can also serve as a destination port for other ports.  
The port redirect function is extremely useful for troubleshooting  
purposes, as it allows traffic to be sent to a particular port(s) where, with  
the use of an analyzer or RMON probe, all current traffic from the source  
port(s) can be examined.

RMON Statistics Screen  
The following definitions explain each field of the RMON Statistics  
screen:  
RMON Index (Read-only)  
This field displays the current Ethernet interface for which statistics are  
being shown. The DLE2X-MA and DLE3X-MA have an embedded  
RMON agent that gathers statistics for each interface on the module.  
Data Source (Read-only)  
This field displays the source of the statistics data that is currently being  
displayed on the screen. Figure 5-35 shows that the data source for this  
RMON index is Interface 1 (port 1) by displaying the name IfIndex.1. If  
the screen was displaying RMON statistics for Interface 22 (port 22), the  
name displayed would be IfIndex.22.  
Owner (Read-only)  
This field displays the name of the entity that configured this entry.  
Status (Read-only)  
The Status field displays the current operating status of the displayed  
interface. This field will display “Valid” or “Invalid”.  
Drop Events (Read-only)  
This field displays the total number of times that the RMON agent was  
forced to discard frames due to the lack of available switch resources.  
The Drop Events field does not display the number of frames  
dropped, it only displays the number of times that the RMON  
agent was forced to discard frames.  
Collisions (Read-only)  
This field displays the total number of collisions that have occurred on  
this interface.  
Broadcast Pkts (Read-only)  
The Broadcast Pkts field displays the total number of good frames that  
were directed to the broadcast address. The value of this field does not  
include multicast frames.

Download from Www.Somanuals.com. All Manuals Search And Download.  
Chapter 5: Local Management  
Multicasts (Read-only)  
The Multicasts field displays the total number of good frames received  
that were directed to a multicast address. The value of this field does not  
include frames directed to the broadcast address.  
CRC Align Errors (Read-only)  
This field displays the number of frames with bad Cyclic Redundancy  
Checks (CRC) received from the network. The CRC is a 4-byte field in  
the data frames that ensures that the data received is the same as the data  
that was originally sent.  
Undersized Pkts (Read-only)  
The Undersized Pkts field displays the number of frames received whose  
size was less than the minimum Ethernet frame size of 64 bytes, not  
including preamble, but have a valid CRC.  
Oversized Pkts (Read-only)  
The Oversized Pkts field displays the number of frames received whose  
size exceeded 1518 data bytes, not including preamble, but have a valid  
CRC.  
Fragments (Read-only)  
This field displays the number of received frames that are not the  
minimum number of bytes in length or received frames that had a bad  
Frame Check Sequence (FCS), were less than 64 bytes in length  
(excluding framing bits, but including FCS bytes), and have an invalid  
CRC.  
It is normal for the Fragments field to increment. This is  
because the RMON agent increments the field when runts are  
detected (which are normal occurrences due to collisions) and  
when noise hits occur.  
Jabbers (Read-only)  
This field displays the total number of frames that were greater than 1518  
bytes and had either a bad FCS or a bad CRC.  
Total Packets (Read-only)  
This field displays the total number of frames (including bad frames,  
broadcast frames, and multicast frames) received on this interface.

Location/Component Layout  
Switch definitions and positions are as follows:  
Switches 1 through 4 – For Digital Equipment Corporation use only.  
Switch 5 – COM Port Autobaud. The default (OFF) position enables  
Autobaud sensing on the COM port for Local Management sessions.  
Changing the switch to the ON position disables Autobaud sensing  
and sets the COM port to 9600 baud for Local Management sessions.  
Switch 6 – Forced BootP. Changing the position of this switch (i.e.,  
moving the switch from one position to the other) clears download  
information from NVRAM and forces the DLE2X-MA and  
DLE3X-MA to download a new image file from a BootP server after  
power to the chassis is restored, or the RESET button is pressed.

Setting the Mode Switch  
After changing the position of switch 6, DO NOT reapply power  
to the chassis or reset the module until there is a station acting  
as a BootP server, which contains the image file.  
Switch 6 – After changing the position of switch 6 and restarting the  
module, the DLE2X-MA and DLE3X-MA request a new image  
download until they either receive a new image or the RESET button  
on the front panel is pressed. When the RESET button is pressed, the  
DLE2X-MA and DLE3X-MA continue trying to contact a BootP  
server, but will time out in approximately one minute. If the module  
times out, the image is downloaded from its FLASH memory.  
Switch 7 – Clear NVRAM. Changing the position of this switch resets  
NVRAM on either the next power up or the next operation of the front  
panel RESET switch. ALL user-entered parameters, such as IP  
addresses, subnet masks, SNMP traps, and bridging functions are  
restored to their factory default settings.  
Switch 8 – Reset Password/Community Strings. Changing the position  
of this switch clears only the user-entered passwords stored in  
NVRAM, and restores the default passwords. Once the DLE2X-MA  
and DLE3X-MA are reset, the passwords can either be reentered or the  
default passwords (Public and ENTER) may be used.  
Do not change the position of switch 8 unless it is necessary to  
reset the module super-user configured passwords to their  
factory default settings.

Installing Optional Fast Ethernet Interface Modules  
To install a Fast Ethernet Interface Module in port slot 25 or 26 of the  
DLE2X-MA, proceed as follows:  
The Fast Ethernet Interface Module and the host module are  
sensitive to static discharges. Use an antistatic wrist strap and  
!
observe all static precautions during this procedure. Failure to  
do so could damage the Fast Ethernet Interface Module or the  
host module.  
The DELF3-UI uses Class 1 lasers. Do not use optical  
instruments to view the laser output. The use of optical  
instruments to view laser output increases eye hazard. When  
viewing the output optical port, power must be removed from  
the network adapter.  
1. Remove the coverplate from the port slot where the Fast Ethernet  
Interface Module will be installed.  
When installing Fast Ethernet Interface Modules in both port  
slots 25 and 26, remove the coverplates from both slot  
openings. In the following instructions, the optional module is  
shown being installed in port slot 26.  
To remove a coverplate, refer to Figure C-3 and proceed as follows:  
a. Remove the two screws fastening the coverplate to the standoffs.  
Save the screws.  
b. Lift and remove the coverplate from the top of the front standoffs.

2. Remove the screw from the rear standoff. Save the screw.  
When installing an DELFX-UI or DELF3-UI module into the  
host module, remove the rubber plug on the SC connector  
before proceeding.  
!
3. Refer to Figure C-4. Gently pull the faceplate of the host module  
forward to allow room for the Fast Ethernet Interface Modules to be  
aligned over the connector.  
4. Carefully lower the Fast Ethernet Interface Module onto the standoffs  
while inserting the module connector into the associated motherboard  
connector.  
When inserting the Fast Ethernet Interface Module into the  
motherboard connector ensure that the pins do not bend, as  
this can damage both the Fast Ethernet Interface Module and  
the motherboard connector.
