Did you turn on the power of Blade Enclosure and Tape Blade 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 and Tape Blade. After making sure that the AC power is supplied to the
CPU blade and Tape Blade (the POWER lamp lit amber), wait for 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 and Tape Blade, the
power-on of CPU blade and Tape 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 and Tape Blade. After that, the CPU blades and Tape 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 and
Tape 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
Tape Blade.
→ When power-on operation for CPU blade is executed, the CPU blade notifies the
EM card of it, and wait for permission. Upon getting permission, the power-on for
Tape Blade is executed. 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):
Does the LAN port support Wake on LAN feature?
→ Tape Blade (containing mezzanine card) does not support Wake on LAN feature.
Fail to power-off:
Did you turn off the power of CPU blade?
→ The power of Tape Blade is linked with the power of the CPU blade and
controlled by EM card. Turn off the power of CPU blade.
Is the POWER switch function of the CPU blade disabled?
→ Restart the CPU blade once and then start the BIOS SETUP utility.
<Menus to check: [Security] – [Power Switch Inhibit]>
The MAC address of the LAN of the Tape Blade is unknown:
→ You can find the MAC address by the label put near the MP connector on the
Tape Blade. See Chapter 3 for details.
Fail to access to internal or external devices (or such devices fail to operate):
Are cables properly connected?
