32 SPARC Enterprise T5440 Server Service Manual • June 2011
▼ Run POST in Maximum Mode
This procedure describes how to run POST when you want maximum testing, as in
the case when you are troubleshooting a server, or verifying a hardware upgrade or
repair.
1. Access the ILOM prompt.
See “Connecting to the Service Processor” on page25.
2. Set the virtual keyswitch to diag so that POST will run in service mode.
3. Reset the system so that POST runs.
There are several ways to initiate a reset. EXAMPLE: show Command Output on
page33 shows a reset using a power cycle command sequence. For other methods,
refer to the SPARC Enterprise T5440 Server Administration Guide.
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
4. Switch to the system console to view the POST output:
If no faults were detected, the system will boot.
EXAMPLE: show Command Output on page 33 depicts abridged POST output.
