Obtaining chassis and component status
The CLI commands in Table 25 provide status and environmental information about the chassis
and its components. These commands provide information only, and they do not interrupt traffic
flow. For more information about these commands, refer to the Fabric OS Command Reference.
Interpreting POST and boot results
The Brocade DCX 8510-4 performs Power On Self Test (POST) by default each time the chassis is
powered on, rebooted, or reset. The Brocade DCX 8510-4 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 8510-4 automatically performs POST each time it is powered on or reset.
To verify that POST has completed without error:
• 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
8510-4 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/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 8510-4
supplier for support.
