Troubleshooting an Operational Problem

To determine whether a fuse has blown in a BLN or BCN, and to isolate and

replace a blown fuse, see the BLN and BCN Fuse Service Manual.

LEDs Are Off

The LEDs on a Fast Routing Engine (FRE

), System Resource Module (SRM), or

link or net module may fail to light for the following reasons:

• The Ethernet transceivers on a slot have lost power.

• A slot is unavailable.

• The backbones are not connected.

• The router has blown a fuse.

• The hardware module is not attached firmly to the backplane.

Look at the GAME messages in the event log to determine the cause of the

problem. If any of these events occurred and a slot is no longer functional, please

call the Nortel Networks Technical Solutions Center to report the problem.

Router Won’t Boot

Troubleshoot the router as follows:

If the router uses a flash memory card, make sure that you inserted it

properly. See the appropriate router maintenance guide for instructions.

Wait five minutes.

If the router’s file system does not contain a configuration file named config,

the router boots automatically with the ti.cfg file after five minutes. The ti.cfg

file contains the minimum configuration required to boot the router and allow

you to use the Technician Interface to access it. Make sure you name the

configuration file config; then, reboot the router.

Note:

If you attempt to boot a router without a storage medium, or attempt to

boot a router that does not have the proper router software image and

configuration files, it will fail to boot and will stay in boot mode. The flash

memory cards ship separately; you must install one unless the router is an

older AN model.
