the system. If show faulty still displays the fault, clear it with the set
command.
4. Perform the following steps to verify the repair:
a. Set the virtual keyswitch to diag so that POST will run in Service mode.
b. Power cycle the system.
Note – The server takes about one minute to power off. Use the show /HOST
command to determine when the host has been powered off. The console will display
status=Powered Off.
c. Switch to the system console to view POST output.
Watch the POST output for possible fault messages. The following output
indicates that POST did not detect any faults:
-> set /SYS/MB/CMP0/BR0/CH0/D0 component_state=Enabled
-> set /SYS/keyswitch_state=Diag
Set ‘keyswitch_state’ to ‘Diag’
