Check Front-Panel Indicators.

The indicator lights (LEDs) on the front of the tower show the
status of the tower, server, and CD-ROM drives.
On the tower nearest the top (when floor mounted):
•
Power is on (green) when power is connected to the tower
and the power switch is on.
On the server module, from left to right:
•
Status is flashing during start-up. When the server/tower
is ready for use, this light is off. It remains off, unless an
error condition occurs; then it goes on.
•
CD is on when a readable CD-ROM is inserted into any con-
nected drive. It remains on unless an error condition occurs;
then it flashes.
•
Network blinks in synchrony with network traffic.
•
Power is on when power is connected from the tower to the
CD-ROM server.
On the HP CD-ROM drives, from left to right:
•
DISC is on (green) when power is connected from the tower
to the CD-ROM drive and a CD is inserted. It is off when no
CD is inserted.
•
ON/BUSY is on (yellow) when power is connected from the
tower to the CD-ROM drive. It blinks in synchrony with
access to an inserted CD. It is off when an inserted CD is not
being accessed.
