Handling Flash Memory Cards to Prevent Static Damage

Always use an antistatic wrist strap when handling flash memory cards; static

electricity can damage them.

Responding to a Failed prom Command

If you reboot after the

prom

command fails, a Nortel Networks representative

must insert new PROM (programmable read-only memory) components on the

router baseboard and write new PROM software to them before the router can

recover.

Preparing to Troubleshoot

The following sections describe how to prepare to troubleshoot router problems:

• “Getting Acquainted with the Troubleshooting Tools”

•“Taking a Snapshot of Your Network

”

Getting Acquainted with the Troubleshooting Tools

Troubleshooting is much more complicated when you have to solve a problem that

requires an urgent solution, and at the same time learn how to use the tools to

solve the problem. Read this section and familiarize yourself with the tools before

you begin troubleshooting. The instructions later in this guide assume you can use

the tools described in this section.

Read the following sections:

•“Using the System Log to Display Event Messages

”

•“Displaying and Changing Configuration Settings and Statistics

”

•“Using the ping Command

”

•“Using the Packet Capture Tool

”

•“Using Inbound Telnet to Access the Technician Interface

”

Caution:

If the Technician Interface

prom

command fails, do not reboot.

Instead, call the Nortel Networks Technical Solutions Center.
