System-board LEDs
Attention: Be careful when sliding the server out of the rack to look at the
system-board LEDs. If the cables on the rear of the server are too short (do not
have enough slack in them), they might be pulled out of the server or broken. To
view the LEDs when the cables are too short, you must turn off the server and
peripherals, remove the cables from the server, remove the server from the rack,
place it on a flat, static-protective surface, reconnect the cables and turn on the
server; then, try to recreate the error.
Statement 27:
CAUTION:
Hazardous moving parts are nearby.
The following illustration shows the light-emitting diodes (LEDs) on the system
board.

Note: A system-board error LED (amber) indicates a problem with the associated
component. An LED that is off when it should be on can indicate a problem with the
associated component.
