ECC memory module, CPU module, keyboard, and mouse. POST also displays messages of the
BIOS SETUP utility, such as the start-up message, while in progress.
With the factory setup of the CPU blade, the NEC logo appears on the display unit (if connected)

unit without pressing Esc . To do so, select "Enabled" for "Boot-time
Diag Screen" under the Advanced menu of the BIOS SETUP utility.

You don't always need to check the POST check results. Check messages that POST displays when:
„
you use the blade server for the first time.
„
the server appears to fail.
„
an error message appears on the display unit.
