DIAGNOSTICS AND TROUBLESHOOTING
Built-in diagnostic capabilities for the FE Switch Modules include:
•
Power-up diagnostics, which are run every time the switch module is
brought on line
brought on line
•
Front panel status LEDs
•
Local and remote loopback tests
•
Temperature sensors
5.1 POWER-UP TESTS
The power-up diagnostics assure that the ATX and all the installed
modules are operating. During diagnostic mode, the status LEDs are used
differently than during normal operation.
modules are operating. During diagnostic mode, the status LEDs are used
differently than during normal operation.
When you power up the ATX, it automatically senses the installed boards
and reassigns port numbers, starting with the PPE as port 1. During a
normal power-up test, the diagnostics test the entire ATX, starting with
the PPE, and going from slot to slot, from the top down. The normal
power-up sequence is described in Chapter 2, Connecting to the
Network.

5.2 POWER-UP RESULTS
After the power-up diagnostic sequence is complete, all status LEDs on
the ATX front panel should be on (lit), indicating that the modules have
passed the power-up tests (see Table 5-1 and Table 5-2). If a switch
module fails a critical test, it is automatically disabled.
