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.

TABLE 25 Environmental status and maintenance commands

Command	Information displayed
sensorShow	Temperature readings for the port blades
	Temperature readings for the CP blades
	Status and RPM of all operational fans
	Status of all operational power supplies
tempShow	Temperature readings for the port blades
	Temperature readings for the CP blades
psShow	Status of all operational power supplies
fanShow	Status and RPM of all operational fans
chassisShow	Serial number, time awake, and additional information about each component
slotShow	Slot occupancy
errShow	System error log. Refer to the Fabric OS Message Reference for more information on the
errDump	messages in this log.

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.
