8-8 Troubleshooting
Did you turn on the power of the Blade Enclosure at least 30 seconds after AC power
is supplied to each power unit?
→ Initialization of BMC takes about 30 seconds after AC power is supplied to the
CPU blade. After making sure that the AC power is supplied to the CPU blade (the
POWER lamp lights amber), wait for 30 seconds or longer and then turn on the
power of the Blade Enclosure by using the POWER switch.
Immediately after power is supplied to the CPU blade, the CPU blade in the next slot
does not power on immediately.
→ Initialization of BMC takes about 30 seconds after AC power is supplied to the
CPU blade. After that, the CPU blades are powered on sequentially. A power-on
delay period {(slot number - 1) × 2 seconds} is set for each CPU blade.
Accordingly, a CPU blade in a high-numbered slot has a longer power-on delay.
It occasionally takes time from the power-on operation to the CPU blade actually
turning on.
→ When the power-on operation is executed, the CPU blade notifies the EM card and
waits for permission to turn on. If the EM card is busy, the power-on may be
delayed.
The remote power-on through network does not work (Wake On LAN does not work):
Is the system shut down forcibly?
→ After a forced shutdown, Wake On LAN does not work. After starting the CPU
blade, perform the normal shutdown procedure.
Fails to power-off:
Is the POWER switch function disabled?
→ Restart the CPU blade and then start the BIOS SETUP utility.
