DVD drive activity LED: When this LED is lit, it indicates that the DVD drive is in
use.
System-power LED: When this LED is lit and not flashing, it indicates that the
server is turned on. When this LED is flashing, it indicates that the server is turned
off and still connected to an ac power source. When this LED is off, it indicates that
ac power is not present, or the power supply or the LED itself has failed. A
system-power LED is also on the rear of the server.
