Checking Status Indicators

Check the LEDs on the ATM link modules or the ARE processor module to verify

that a module is operating after installation.

ARE DS-3, E-3, and SONET/SDH Link Module LEDs

Figure 3-1 shows the LEDs on the ARE E-3 link module. The LEDs are identical

on the ARE DS-3 link module.

Figure 3-1. ARE E-3 Link Module LEDs

Figure 3-2 shows the LEDs on the ARE SONET/SDH link module. The LEDs are

identical on the ARE STS-3/STM-1 SONET/SDH MMF,

STS-3/STM-1 SONET/SDH SMF, and OC-3 link modules.

Note:

We recommend that you issue the

diags

command to the associated slot,

using the Nortel Networks Technician Interface, immediately after you insert a

link module. (Refer to Using Technician Interface Software if you use router

software or Troubleshooting and Testing if you use BayStream software.)

Otherwise, the link module FAIL LED will remain lit, indicating that

diagnostics have not run on the Intelligent Link Interface (ILI). However, even

if you do not issue the

diags

command, the link module initializes and

becomes operational as long as the board functions properly and contains the

correct interface configurations.
