CHAPTER 5
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
•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.
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.
