System Power Light: When this green light is on, system power is present
in the server. When this light flashes, the server is in standby mode (the
system power supply is turned off and ac current is present). When this light
is off, either a power supply, ac power, or a light has failed.
Attention:
If this light is off, it does not mean there is no electrical current present in the
server. The light might be burned out. To remove all electrical current from
the server, you must unplug the server power cords from the electrical outlets.

self-test (POST) completes without any errors.

activity on a hard disk drive.
Processor 1 Activity Light: This green light is on when there is micro-
processor 1 activity.
Processor 2 Activity Light: This green light is on when there is micro-
processor 2 activity.
Information Light: This amber light is on when the information log contains
information about certain conditions in your server that might affect perform-
ance. For example, the light will be on if your server does not have redun-
dant power. A light on the diagnostic LED panel will also be on.
System Error Light: This amber light is on when a system error occurs. A
light on the diagnostic LED panel will also be on to further isolate the error.

there is transmit or receive activity to or from the server.
