Troubleshooting 8-9
‰
Did you turn on the power of Blade Enclosure within 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 lit amber), wait for about 30 seconds or longer, then turn on the
power of Blade Enclosure by using the POWER switch.
‰
Immediately after the power is supplied to the CPU blade, the CPU blade in the slot
having the larger number is delayed.
→
Initialization of BMC is performed for about 30 seconds after power-on of CPU
blade. After that, the CPU blades are powered on sequentially. At power-on
sequence, a waiting time {(slot number - 1)
×
2 seconds} is inserted between
blades. Accordingly, the CPU blade in the slot having the larger number is
delayed.
‰
It occasionally takes time from power-on operation to CPU blade to turning on the
power supply.
→
When power-on operation is executed, the CPU blade notifies the EM card of it,
and wait for permission. If the EM card is processing other task and it is busy,
permission for power-on is delayed.
The remote power-on through network does not work (Wake On LAN does not work):
‰
Is the system shut down forcibly?
→
After the forced shutdown (or pressing the POWER switch on the CPU blade
brings the power of the CPU blade to be turned off forcibly), Wake On LAN does
not work. After starting the CPU blade once, perform the normal shutdown
processing.
Fail to power-off:
‰
Is the POWER switch function disabled?
→
Restart the CPU blade once and then start the BIOS SETUP utility.
