Power-On Self Test

When you start the switch, it will run a power-on self-test to ensure that all the devices are working correctly. During this test, the switch will detect and start any module found in an expansion slot.

The module will then perform an internal power-on self test. During the entire test, the DIAG and ERR LEDs will be lit while the other LEDs may turn on and off.

The test lasts a few minutes. If no problems are found, the DIAG and ERR LEDs turn off and the module enters its normal operational state. If a problem is found, the DIAG LED will turn off and the ERR LED will remain on. Messages in the message log or on the console will indicate what the problem is.

➽Note: Switch Console message:

Press RETURN key to activate console...

means that the console is available, but it takes more time to activate the module. You can check if they are up in the Configuration→ Module Information menu.
