Interpreting POST and Boot Results
The device performs a power-on self-test (POST) by default each time the device is powered on, rebooted, or reset. The
device can be rebooted using the
reboot
command to reboot each CP individually) or the
fastBoot
command. 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 device automatically performs POST each time it is powered on or reset.
To verify that POST has completed without error, do the following tasks:
•
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 device 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
Brocade Fabric OS Administration Guide
.
•
Verify that the switch prompt displays when POST completes.
If it does not display, POST was not successfully completed. Contact the device supplier for support.
•
Review the system error log using the
errShow
or
errDump
commands.
Any errors detected during POST are written to the system log, which is accessible through the
errShow
command.
For information about error messages, refer to the
Brocade Fabric OS Message Reference Manual Manual
.
