Power Problems; Management-Module Problems; Blower Module Problems; Optional Device Problems - IBM 8677 - BladeCenter Rack-mountable - Power Supply Installation And User Manual

Power problems

Symptom
The BladeCenter unit does
not start.

Management-module problems

Symptom
The management module
does not switch to the
redundant module.

Blower module problems

Symptom
The blower module operates
at full speed, with no
regulation.

Optional device problems

Symptom
An IBM optional device does
not operate correctly after
installation.
Suggested action
v Make sure that the power cords are correctly connected to the power modules in
the BladeCenter unit.
v Make sure that the 220-volt PDU or electrical outlet is working correctly.
v Make sure that both the ac and dc LEDs on each power module are lit and that
amber error LED (2320-watt power modules only) is not lit.
v If you just installed an optional device, remove it, and restart the BladeCenter unit.
If the BladeCenter unit now starts, you might have installed more devices than the
power module supports.
If the problem remains, call for service.
Suggested action
v Wait for 45 minutes to complete the management-module data transfer.
v Make sure that the management module that is removed is replaced with the same
type of module.
v Replace the management module.
If the problem remains, call for service.
Suggested action
Make sure that:
v Both blower modules are functioning (neither has failed).
v Each power module is connected to an ac power source. A power module that is
not connected to an ac power source creates a nonredundant power condition and
causes the blower modules to operate at full speed.
v The management module is installed and working.
v Each module bay contains a module or filler module.
If the problem remains, call for service.
Suggested action
Make sure that:
v The device is designed for the BladeCenter unit. See http//:www.ibm.com/servers/
eserver/serverproven/compat/us/ for ServerProven
v You followed the installation instructions that come with the device.
v The device is installed correctly.
v You have not loosened any other installed devices or cables.
If the problem remains, call for service.
