DIAGNOSTICS AND TROUBLESHOOTING

5.1 POWER-UP DIAGNOSTICS

5.1.1Power-up Tests

The power-up diagnostics assure that the ATX and all the installed modules are operational. During diagnostic mode, the status LEDs are used differently than during normal operation.

When the ATX is powered-up, 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 proceeding slot by slot from the top down. The normal power-up sequence is described in Chapter 2, Connecting to the Network.
