Did you turn on the power of Blade Enclosure within 60 seconds after AC power is supplied to each

power unit?
→ After the POWER LED lights amber, wait for 60 seconds or longer, and then turn on the power of
Blade Enclosure by using the POWER switch.
The power-on of the CPU blade in the slot having the larger number is delayed.

→ If the CPU blade is turned on by the above procedure, the power-on of the CPU blade in the slot
having the larger number is delayed.
It takes time to turn on the power supply.

→ When power-on operation is executed, the CPU blade notifies the EM card of it, and then turns on
the power supply. If the EM card is busy because it is processing other tasks, the power -on
operation may take time.
Wake On Ring is set to Enable in the BIOS setup utility.

→ When Wake On Ring is enabled, remote power-on is not allowed. Power on the server by
pressing the POWER switch on the server. If you change the AC Link setting while Wake On Ring
is enabled, you need to press the POWER switch twice to power on the server.
[?] 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 for 4 seconds or
longer), Wake On LAN does not work. After starting the CPU blade once, perform the normal
shutdown processing.
[?] POST runs several times:
→ POST may run several times depending on system configuration or boot control feature specified
on EM card. However, this does not affect the system operation.
[?] "System Configuration Data Read Error" appears and POST pauses:
Did you perform any of the following operations during POST?

– Pressed POWER switch of the CPU blade to forcedly power off the CPU blade.
– Pressed RESET switch of the CPU blade to provide hardware reset.
– Removed the CPU blade from Blade Enclosure.
– Disconnected the power cord from Blade Enclosure.
→ Contact your service representative.
[?] The MAC address of the onboard LAN of the CPU blade is unknown:
→ You can find the MAC address by the label put near the MP connector on the CPU blade. Refer to
Chapter 2 (2.1.1 Checking MAC address) in User's Guide.
