Interpreting POST and boot results

The PowerConnect B-DCX-4S performs Power On Self Test (POST) by default each time the chassis
is powered on, rebooted, or reset. The PowerConnect B-DCX-4S 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.

Components").
If one or more LEDs do not return to a normal state, and this is not due to the PowerConnect
B-DCX-4S 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 PowerConnect
B-DCX-4S supplier for support.
