2. Press the power button on the next blade server in the scalable blade complex. System-
board LEDs are lit for any problem components on that blade server.
System Board
This amber LED indicates that there is a problem with the system board. If this amber LED is lit,
complete the following steps:
1. Restart the blade server.
2. If the problem remains, replace the system board (see "Removing the system-board
assembly - BladeCenter HX5" on page 140 and "Installing the system-board assembly -
BladeCenter HX5" on page 142 for instructions).
NMI
This amber LED indicates that a non-maskable interrupt (NMI) occurred. If the NMI button was
not pressed, complete the following steps:
1. Check the advanced management module event log or the IMM event log for any errors
related to this blade server and solve them.
2. Restart the blade server.
3. Replace the system board (see "Removing the system-board assembly - BladeCenter
HX5" on page 140 and "Installing the system-board assembly - BladeCenter HX5" on
page 142 for instructions).
Mismatch
This amber LED is lit if there are two processors in the blade server and they are not the same
type and speed. If this LED is lit, make sure that both processors are identical.
Step 5.
If an IBM MAX5 expansion blade is installed, check the front bezel for an orange glow, which
indicates that one or more LEDs on the IBM MAX5 expansion blade system board is lit. To view the
LEDs on the IBM MAX5 expansion blade system board, complete the following steps:
Note: If there is an orange glow, it will be referred to as MEU Fault in the system event log.
a.
Remove the blade server from the BladeCenter chassis, (see "Removing the blade server from
the BladeCenter chassis" on page 66 for instructions).
b.
Carefully lay the blade server on a flat, static-protective surface.
c.
Remove the IBM MAX5 expansion blade (see "Removing an IBM MAX5 expansion blade" on
page 87 for instructions).
d.
Open the cover on the expansion blade (see "Removing the blade server cover" on page 71 for
instructions).
e.
Press the light path button on the light path diagnostics panel and view the LEDs that are lit.
