Light Path Diagnostics Leds - IBM HS40 - BladeCenter - 8839 Installation And User Manual

Light path diagnostics LEDs

Power is available to relight the light path diagnostics LEDs for a short period of
time after the blade server is removed from the BladeCenter unit. During that period
of time, you can relight the light path diagnostics LEDs for a maximum of 25
seconds (or less, depending on the number of LEDs that are lit and the length of
time the blade server is removed from the BladeCenter unit) by pressing the light
path diagnostics button on the I/O board or processor board.
The light path diagnostics LEDs on the I/O board and processor board light when
the light path diagnostics buttons are pressed if power is available to relight the
blade-error LEDs. If the light path diagnostics LEDs are not lit when the light path
diagnostics buttons are pressed, no power is available to light the blade-error LEDs,
and they will be unable to provide any diagnostic information.
Table 7 describes the light path diagnostic LEDs on the I/O board. Table 8 on page
75 describes the light path diagnostic LEDs on the processor board. See the
illustrations on page 72 and page 73 for LED locations.
If an error has occurred, power is available to light the LEDs, and no light path
diagnostic LEDs are lit, the error cannot be diagnosed, or the service processor has
failed. The error is not represented by a light path diagnostic LED and you should
check the system error log in the BladeCenter management module for information
about the error.

Action
Replace the blade server cover and reinsert the blade
server in a powered BladeCenter unit; then, after the
blade server has been in the BladeCenter unit for several
minutes, remove it and try to light the light path
diagnostics LED.
If the problem remains, have the blade server serviced.
No action required. IDE is not supported for this blade
server model.
Replace the blade server cover, reinsert the blade server
in the BladeCenter unit, and then restart the server.
If the problem remains, have the blade server serviced.
Check all interconnecting cables between the blade server
I/O board and the blade server processor board for proper
seating.
If the problem remains, have the blade server serviced.
Replace the blade server cover, reinsert the blade server
in the BladeCenter unit, and then restart the server.
If the problem remains, have the blade server serviced.
