4 Requirements for Use
Different LED combinations indicate the tape drive’s operating state, as follows:
When the top (amber) LED is on or flashing, the tape drive either has an error or needs to be cleaned.
When the middle LED is on or flashing, SCSI bus activity is occurring. The middle LED can be green or amber, as follows:
∙When this LED is amber, the tape loaded in the tape drive is in compressed format (8500c or 8200c).
∙When this LED is green, the tape loaded in the tape drive is in uncompressed format (8500 or 8200).
When the bottom (green) LED is on or flashing, tape motion is occurring.

The LED is on. | The LED is off. | The LED is flashing: |
slow = 1 flash/second (0.94 Hz) jfast = 4 flashes/second (3.76 Hz)
irregular = Rate of flash varies with SCSI bus activity. If the tape drive is not connected to the bus, the LED will be off.
