Status lights
Located next to the tape drive opening are two lights that inform you of the
status of tape operations. The light on the left is the tape light, and the light
on the right is the clean light. A solid green tape light indicates normal
operation and a solid amber clean light indicates a warning condition. A
flashing green tape light indicates activity between the tape drive and the
SCSI bus. A flashing amber clean light indicates the tape in the drive is
worn or the tape-drive head needs to be cleaned.
The following table lists all the possible meanings of the status lights.
