Workgroup Server 80 & 95: Reading Status Lights

The front panel has two bi-color lights (LEDs). Green is used to indicate normal operation and Amber is used to imply warning conditions. Pulsing usually shows activity between the drive and the SCSI bus. If the cassette Light (Left) shows a steady Amber, this indicates that the cassette is write protected. If the Drive Light (Right) shows a steady Amber, this indicates a fault condition.

The following table lists the possibilities:
