Use this information to locate and identify the light path
diagnostics LEDs.
Before you work inside the blade server to view light
path diagnostics LEDs, read Safety and Installation guidelines.
If an
error occurs, view the light path diagnostics LEDs in the following
order:
-
Look at the control panel on the front of the blade server
(see Blade server controls and LEDs).
- If the information LED is lit, it indicates that information about
a suboptimal condition in the blade server is available in the BMC
log or in the management-module event log.
- If the blade-error LED is lit, it indicates that an error has
occurred; view the light path diagnostics panel and LEDs to isolate
the failing component.
-
To view the light path diagnostics
panel and LEDs, complete the following steps:
-
Remove the blade server from the BladeCenter
unit. See Removing the blade server from the BladeCenter unit.
-
Place the blade server on a flat, static-protective
surface.
-
Remove the cover from the blade
server. See Opening the blade server cover.
-
Press and hold the light path diagnostics switch to
light the LEDs of the failing components in the blade server. The
LEDs will remain lit for as long as you press the switch, to a maximum
of 25 seconds.
The following illustration shows the locations of the
system-board error LEDs.
