3. Once you know the general type of error and the general location of the
component involved, the next step is to check the system service label on the
outside of the server.
This label gives an overview of internal components that correspond to many of
the LEDs on the light path diagnostics panel and can help to view lit LEDs
inside the server.
Note: Some of the LEDs on the light path diagnostics panel will not have a
corresponding LED lit on the system board. For example:
v
LEDs for the power supplies, fans, and hard disk drives are located on
or near the individual component.
v
Some error conditions are corrected by taking an action not related to
one particular component; see step 5.
4. If the lit LED on the light path diagnostics panel refers to a specific internal
component as indicated in step 3, look on the system board for lit error LEDs
(see “System-board LEDs” on page 83). For example, a microprocessor error
will light the LED next to the failing microprocessor.
The error LEDs on the system board will only be lit when there is power to the
server. To view them, read “Working inside the server with the power on” on
page 12; then, remove the cover and look for any lit error LEDs.
If the lit LED on the light path diagnostics panel does not refer to a specific
internal component, continue with step 5.
5. Go to the table at “Light path diagnostic errors” on page 114 and find the entry
for the associated lit LED; then, replace the indicated component or take the
indicated action.
Notes:
v
The system-error log and the BMC log might contain additional information that will be
helpful before replacing a component.
v If an LED on the light path diagnostics panel is lit and the system-error LED is not lit, there
is probably an LED problem. Run LED diagnostics.
