Chapter 1 Maintenance
Have the CPU blade (containing mezzanine card) and switch modules been installed in proper
position?
→
Refer to the User's Guide of Blade Enclosure for proper installation locations.
Did you turn on the power of Blade Enclosure within 60 seconds after AC power is supplied to each
power unit?
→
Initialization of BMC takes about 60 seconds after AC power is supplied to the CPU blade. After
making sure that the AC power is supplied to the CPU blade (POWER LED lit amber), wait for
about 60 seconds or longer, then turn on the power of Blade Enclosure by using 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 60 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 power-on of 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.
Is Wake On Ring set to Enable in the BIOS setup?
→
When Wake On Ring is enabled, remote power on is not allowed, and you can power on the
server only by using POWER switch on the server. If you change the AC Link setting while
Wake On Ring is enabled, you need to press POWER switch twice to start up 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 POWER switch on the CPU blade for 4 seconds or
longer 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.
[?] 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 operation 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 on the LAN riser card in the CPU blade. Refer to
Chapter 2 (2.1.1 Checking MAC Address) in User's Guide.
