Diagnostic Leds - IBM 8852 - BladeCenter H Rack-mountable Installation And User Manual

Diagnostic LEDs

Use the following table to find solutions to problems that are identified by LEDs on
the front and rear BladeCenter system LED panels.
Table 1. Diagnostic LEDs
Lit LED Cause
BladeCenter system LED panel
Location A condition has occurred in the BladeCenter
unit that has caused the remote system
management to identify the BladeCenter unit
as needing attention.
Over-temperature The system temperature has exceeded a
threshold level.
Information A noncritical event has occurred that should be
looked at, such as the wrong I/O module
inserted in a bay, or power requirements that
exceed the capacity of power modules
currently installed.
System error A critical system error has occurred, such as
nonredundancy on the power modules or a
system error in a blade.
Action
Look for any information or error LEDs on the
system LED panels, the modules, and the
blade servers in this BladeCenter unit, and see
the BladeCenter H Problem Determination and
Service Guide for more information.
1. Determine whether a blower module has
failed. If it has, replace the blower module
as soon as possible, to regain redundancy.
2. Make sure that the room temperature is not
too high. (See "Features and specifications"
on page 3 for temperature information.)
3. Determine whether a blade server has a lit
error LED. If it does, see the
documentation that comes with the blade
server.
4. Make sure that there is a blade server,
module, or filler installed in each bay.
1. Check the management-module event log
for the messages.
2. Check the LEDs on the BladeCenter unit
and the blade servers to isolate the
component

v If the error LED is on a module, see the
BladeCenter H Problem Determination
and Service Guide for more information.
v If the error LED is on a blade server, see
the documentation that comes with the
