Light path diagnostics
Light path diagnostics is a system of LEDs on various external and internal
components of the server that leads you to the failed component.
When an error occurs, LEDs are lit throughout the server. By viewing the LEDs in
a particular order, you can often identify the source of the error.
When LEDs are lit to indicate an error, they remain lit when the server is turned
off, provided that the server is still connected to power and the power supply is
operating correctly and the top cover is closed and latched correctly.
Before you work inside the server to view light path diagnostics LEDs, read the
safety information that begins on page “Safety” on page vii and “Handling
static-sensitive devices” on page 34.
If an error occurs, view the light path diagnostics LEDs in the following order:
1. Look at the operator information panel on the front of the server.
v
If the Log LED is lit, it indicates that information about a suboptimal
condition in the server is available in the IMM system-event log or in the
system-event log.
v
If the system-error LED is lit, it indicates that an error has occurred; go to
step 2.
Note: The initial server configuration will not include the light path
diagnostics panel. Step 2 is for users who have upgraded the operator
information panel to the advanced operator information panel. If the server
only has the operator information panel, please go to step 3.
2. To view the advanced operator information panel, press the blue latch on the
right of the operator panel. Lit LEDs on this panel indicate the type of error
that has occurred.
Note any LEDs that are lit, and then reinstall the light path diagnostics panel in
the server.
3. Remove the server top cover and look inside the server for lit LEDs. Certain
components inside the server have LEDs that are lit to indicate the location of a
problem.
The following illustration shows the LEDs on the system board.
