System status/fault LED
When this green LED is lit continuously (not flashing), it indicates normal
operation and that no system errors have occurred.
Hard disk drive activity/failure LED
When this amber LED is flashing, it indicates that a hard disk drive is in
use. When this LED is lit continuously (not flashing), it indicates a hard disk
drive failure.
Ethernet1/Ethernet2 activity LEDs
There are two Ethernet activity LEDs, one for each Ethernet controller in
your server. When each LED is flashing, it indicates that there is activity
between one of the Ethernet controllers and the network. The LEDs are off
if there is no Ethernet connection and are lit continuously if there is a
connection with no activity. Ethernet link status and speed LEDs are also on
each Ethernet connector on the rear of the server.
