 Has the EM card been initialized?
→ If the EM card is not initialized, the power unit does not supply the power to the
CPU blade and Tape Blade.
 Does the Blade Enclosure contain the required number of fans in proper location?
→ Refer to the User's Guide of Blade Enclosure for the required number of fans and
their installation locations.
 Have the CPU blade (containing mezzanine card), Tape Blade (containing mezzanine
card), and switch modules been installed in proper position?
→ See Chapter 9 or refer to the User's Guide of Blade Enclosure for proper
installation locations.
 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.
