System information

4 Deploying Samba on IBM Eserver BladeCenter
Over- temperature This is an amber LED which will report any over-temperature
conditions that occur either in the BladeCenter chassis or the blade
servers. If an over-temperature condition occurs, the IBM Eserver
BladeCenter may increase the speed of the blower to correct this, in
which case the LED will automatically be turned off.
Information The information LED is also amber; this LED reports non-critical
events. These events are recorded in the Error log. This LED must be
manually switched off via the management module.
System Error Again, this is an amber LED which reports when a system error
occurs. This LED reports errors such as a failure of a power, blower or
switch modules. It will also be on if a system error occurs on a blade.
The failed component’s LED will also be on to help isolate the error.
These system LEDs are also located on the rear of the BladeCenter chassis under blower
module 2.

As we discussed earlier, the BladeCenter chassis is capable of housing several hot swap and
redundant components, such as:
򐂰 Power supply modules
򐂰 Switch modules
򐂰 Management modules
򐂰 Blower modules
In Figure 1-3 on page 5, you can see where each of these components should be located in
the rear of the IBM Eserver BladeCenter.
