Interpreting POST and boot results

The Brocade DCX 8510-8 performs Power-On Self-Test (POST) by default each time the chassis is

powered on, rebooted, or reset. The Brocade DCX 8510-8 can be rebooted using the reboot (to

reboot each CP individually) or fastBoot commands. The fastBoot command reboots the switches

without running POST. If the active CP blade is rebooted, it fails over to the standby CP blade.

POST

The Brocade DCX 8510-8 automatically performs POST each time it is powered on or reset.

To verify that POST has completed without error, do the following:

• Verify that all LEDs return to a normal state after POST completes.

If one or more LEDs do not return to a normal state, and this is not due to the Brocade DCX 8510-8

being set to beacon, refer to the relevant LED table to identify and correct the problem. For port

blades, and CP and core switch blades, the slotShow command can be used to check the status of

the slots. For information about turning beaconing on or off, refer to the Fabric OS Administrator's

Guide.

• Verify that the switch prompt displays when POST completes.

If it does not display, POST was not successfully completed. Contact the Brocade DCX 8510-8

supplier for support.

• Review the system error log using the errShow or errDump commands.
