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 expansion blade” on page 88).
2. Install the BladeCenter HX5 in the chassis (see “Installing a blade server in a BladeCenter chassis”
3. Restart the blade server.
4. Check system-event and IMM/AMM logs related to memory and resolve those events (see “POST
error codes” on page 149 and “IMM error codes in AMM” on page 162).
5. If the problem remains, replace the system board on the IBM MAX5(see “Removing the system-
board assembly - BladeCenter HX5” on page 140 and “Installing the system-board assembly -
BladeCenter HX5” on page 142 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 system board. See “Light path
diagnostics LEDs - IBM MAX5” on page 209 for additional information.See the
Problem Determination
and Service Guide
for additional information..
The Light path power (LP2) LED is referred to as MEU LED Power in the system event log.
See “Light path diagnostics LEDs - IBM MAX5” on page 209 for more information about the LEDs on the IBM
MAX5 expansion blade.
Scalability indicators
The BladeCenter HX5 blade server provides scalability indicators, which are viewable through the front bezel
of the blade server when it is installed in a BladeCenter chassis. The scalability indicators remain lit until the
blade server is started.
The BladeCenter HX5 blade server can be deployed as a stand-alone blade server. It can also be combined
with another BladeCenter HX5 blade server to form a scalable blade complex. When two BladeCenter HX5
blade servers are combined into a scalable blade complex, you can specify that they operate as a single
hardware partition or operate in stand-alone mode.
The scalability indicators show whether a BladeCenter HX5 blade server is a stand-alone blade server or a
node in a scalable blade complex operating as a single hardware partition.
When a BladeCenter HX5 blade server is a stand-alone blade server, the scalability indicators continually
move up and down the front of the bezel.
