C Obtaining chassis and component status 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.

Refer to the Fabric OS Message Reference for more information on the messages in this log. 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. POST To verify that POST has completed without error: • Verify that all LEDs return to a normal state after POST completes (Chapter 4, "Monitor System 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. • Review the system error log using the errShow or errDump commands. 106 PowerConnect B-DCX-4S Backbone Hardware Reference Manual 53-1001808-01

PowerConnect B-DCX-4S Backbone Hardware Reference Manual

Obtaining chassis and component status
C
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 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.
POST
To verify that POST has completed without error:
•
Verify that all LEDs return to a normal state after POST completes (
Chapter 4, “Monitor System
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.
•
Review the system error log using the
errShow
or
errDump
commands.
