ATM Multimode Fiber
Module Installation Guide
For the CoreBuilder™ 2500 System
Module Description
This module provides a single OC-3 155 Mbps interface for multimode
fiber in a high-speed slot on the CoreBuilder 2500 system. You can mix
and match two high-speed modules in any configuration, including
ATM and FDDI, ATM and 100BASE-T, FDDI and 100BASE-T, and FDDI
and FDDI. For information on configuring the ATM module, see the
Administration Console User Guide. This figure shows the ATM
module’s front panel.

The ATM module requires revision 8.1.1 or higher of LANplex® 2500
system software. A system software revision supporting this module is
available from the 3Com BBS, 3Com’s Internet FTP site (ftp.3Com.com),
or 3ComForum on CompuServe online service.
If you combine two or more Ethernet 10BASE-FL modules with ATM
modules, you must use the 10BASE-FL module, part number
3C201400A. System software release 8.1.1 or higher does not allow
the system to boot if you use any of the “older”10BASE-FL modules
(3C201400) with the ATM module.
The new 3C201400A module has a label with “10BASE-FL” on the top
left-hand corner of the front panel. (Earlier versions have no label.)
You can also check via software through the Administration Console
for the new module revision (4.0 or above). For more details, see “ATM
Configurations” in this guide or call your local 3Com sales
representative.

The associated port is active.
An error condition has occurred with the
associated port or the port has been disabled
from the Administration Console.
Electrostatic discharge (ESD) can damage components on the module.
ESD, which occurs when the module is improperly handled, can cause
complete or intermittent module failures. To prevent ESD-related
damage:
■
Keep the module in its antistatic bag until you are ready to install it.
■
When you handle the module, always wear the enclosed ESD wrist
strap, ensuring that it makes good skin contact and is grounded
appropriately.
■
Always handle the module by its edges.
■
Do not touch the component’s pins, leads, or solder connections.

Before you install your new module, follow the appropriate
preinstallation instructions, depending on whether you are installing an
ATM module in an empty slot or replacing an old one.
Your CoreBuilder 2500 system arrives with no modules installed and
with protective faceplates covering unused slots. Remove the
protective faceplate covering the selected slot before you install the
module.
CAUTION: When you handle modules, 3Com recommends that you
always use the enclosed wrist strap connected to a proper ground.
See “Safety Information.”
To remove the faceplate:
1 Loosen the two captive screws that secure the faceplate to the chassis.
2 Pull the faceplate away from the system, as shown in this figure. Save
the faceplate for future use.

Read before
replacing a module
You can replace a module while the system is on. Replacing the module
requires that you remove the attached cables from the module’s ports
before you install the new module.
To replace a module:
1 Record the cabling so that you can correctly recable the new module,
and then disconnect the cables from the old module’s ports, as shown
in the next figure.
2 Loosen the two captive screws that secure the module to the chassis.
3 Carefully pull the module out of the chassis.

The CoreBuilder 2500 system automatically resets itself when you install
a module with the system on.
If you physically change the configuration after you define an IP
interface, the port designated for that interface may no longer be valid.
You may have to redefine the interface. For information on defining
an IP interface, see the Administration Console User Guide for your
system.

To install the ATM module, follow the appropriate instructions in
“Before You Install,” and then take these steps:
1 Be sure that you are properly grounded. See “Safety Information.”
2 Remove the module from its antistatic bag. Save the bag for future
storage.
WARNING: If the system is turned on when you are replacing the
module, do not insert any metal objects into the open slot (for
example, a screwdriver or hand with jewelry). Doing so could cause
burns or other bodily harm.
3 Carefully place the module between the guides of the selected slot and
slide the module into the chassis, as shown in this figure.

4 To seat the module, firmly push it inward to engage the connectors for
the module and backplane. You will feel a slight resistance as the
connectors engage.
CAUTION: If the resistance seems too great, the module and
backplane connectors might not be aligned properly. Forcing the
module inward could damage the board or backplane connectors. If
necessary, remove and reinsert the module, ensuring that the
connectors are properly aligned.
5 Tighten the captive screws to secure the module in the chassis.

Module Diagnostics
Module diagnostic software runs when you turn the system on or
when you replace a module with the system on. Watch for this LED
activity:
■
During diagnostics, the module’s Port Status Error LED lights yellow.
■
When diagnostics are successfully completed, the Port Status Active
LED lights green.
■
If the port status Error LED remains yellow, the port is not
operating.
■
If the module’s Board Error LED lights yellow, the module has failed
a diagnostic test.
To troubleshoot module failures, see Chapter 7: Troubleshooting the
System in your Getting Started Guide.
ATM
Configurations
Certain restrictions apply to configurations that include ATM modules
and older CoreBuilder 2500 Ethernet 10BASE-FL modules (3C201400).
The older version of these Ethernet 10BASE-FL modules can, in some
ATM configurations, cause the CoreBuilder system to draw excessive
power, which results in system failure.
All CoreBuilder 2500 systems that operate with a single (old) Ethernet
10BASE-FL module and an ATM module are at no risk of exceeding
power limitations.
Error Conditions
If your CoreBuilder chassis contains more than one older Ethernet
10BASE-FL module and either the MMF or the SMF ATM module,
certain combinations of modules draw too much current and exceed
the system limit of 14 amps. The next section describes the
unsupported configurations in detail.
Revision 8.1.1 and greater of LANplex 2500 and CoreBuilder 2500
software detect unsupported configurations during system power-up.
■
If the software detects one of these configurations, it reports a
critical error condition and does not bring the system online.
■
In addition, all LEDs on the system light and the configuration LED
flashes to indicate the critical error.
ATM Configurations
■
7
The following error message appears on the Administration
Console screen:
FATAL Error .....
Option Module Configuration Not Supported.
Illegal Combination of Adapter Cards
SYSTEM HALTED!
An error condition can also occur if a new, low-power Ethernet
10BASE-FL module is present and is not functioning properly. In this
case, a message similar to the following one appears on the
Administration Console:
An Overcurrent Condition Has Occurred For The Adapter Card In
Slot - 3 or 4
Please Remove This Adapter Card and Contact 3Com Technical
Support.
SYSTEM HALTED!
Configuration
Limitations
Table 1 indicates which CoreBuilder 2500 system configurations are
supported based on the electrical current that they draw at power-up.
Some configurations depend on the motherboard chassis revision
level. Verify your system’s revision level:
■
Identify Revision 8 motherboards by the 3C250100A/3C250200A
label on the lower-right corner of the front panel.
■
Identify Revision 6 and 7 motherboards by entering the system
display command at the top level of the Administration Console.
