Fault LED
When this amber LED is lit, it indicates that a system error has occurred in
the blade server. In addition, the fault LED on the chassis system LED
panel is lit. See the Problem Determination and Service Guide
The fault LED turns off only after the error is corrected.
Note: When the fault LED turns off, you should also clear the IMM event
log. Use the Setup utility to clear the IMM event log.
IBM MAX5 LEDs
When there is a fault on the IBM MAX5 expansion blade, the front bezel of the
IBM MAX5 expansion blade will appear to have an orange glow. You can press the
light path button on the system board of the IBM MAX5 expansion blade to
determine which LEDs are lit.
Note: If there is an orange glow, it will be referred to as MEU (Memory Expansion
Unit) Fault in the system event log.
The following LEDs are available on the IBM MAX5 expansion blade light path
diagnostic panel:
See Light Path Below (LP1)
This amber LED indicates that there is a problem with the BladeCenter
HX5 to which the IBM MAX5 expansion blade was attached. If this LED is
lit, complete the following steps:
1. Remove the IBM MAX5 expansion blade (see "Removing an IBM
MAX5" on page 30).
2. Press the power button on the BladeCenter HX5 blade server to
determine which LEDs are lit on the blade server.
The See Light Path Below (LP1) LED is referred to as MEU Look Below in
the system event log.
System Board (S BRD)
This amber LED indicates that there is a problem with the system board. If
this amber LED is lit, complete the following steps:
1. Install the IBM MAX5 (see "Installing an IBM MAX5" on page 62).
2. Install the BladeCenter HX5 in the chassis (see "Installing a blade
server in a BladeCenter chassis" on page 68).
3. Restart the blade server.
4. If the problem remains, replace the system board on the IBM MAX5
(see the Problem Determination and Service Guide for instructions).
The System Board (S BRD) LED is referred to as MEU Error in the system
event log.
Light path power (LP2)
This amber LED indicates that one or more LEDs are lit on the IBM MAX5
