Reading the Busy Light
The CD-ROM busy light shows the status of the drive during the self
test and during activity with the host system.
The CD-ROM drive performs the self test when one of the following
happens:
•
You load a disc and close the Disc Tray.
•
You turn on the workstation with a disc already loaded in the
CD-ROM drive.
For the self test, the busy light operates in the following sequence:
1. Light On – The busy light goes on when the disc loads into
the drive.
2. Light Flashing – The light flashes six times while a read test
is performed on the disc.
3. Light Off – The light goes off when the self test is com-
plete.
The busy light stays on after the self test when one of the following
conditions exist:
•
A defective disc
•
A disc insertion error (for example, an upside-down disc)
•
No disc present
The busy light goes off when one of the following conditions exist:
•
A CD-ROM drive power failure exists.
•
The drive is idle on the SCSI bus.
The busy light flashes during normal activity with the system.
