Table 36 LED Lighting Pattern

During POST

If the tape drive fails POST, check for the following possible problems:

• The tape drive is not receiving adequate power (try a new power

cable or a different outlet).

• The tape drive is not properly connected to the host computer and

other SCSI devices.

If any of these problems exist, correct the problem, turn off the tape drive,

and turn it back on to restart POST. For additional troubleshooting

guidelines, see POST and SCSI Troubleshooting

on page 124.

Stage What You Observe

(Power cycle)

• All LEDs illuminate for approximately one

second.

2 • The left LED turns orange, then all LEDs turn off

simultaneously.

3 This stage typically lasts 5 to 10 seconds.

• The left and right LEDs remain off.

• The middle LED flashes until POST completes.

4When POST is complete:

• The middle LED stops flashing and remains

illuminated.

• The left and right LEDs remain off.

POST failure If POST fails:

• The middle and right LEDs illuminate steadily.

• The left LED flashes.

Note: If a cartridge is loaded when power is applied, all stages

remain the same except stage 3. It may take considerably

longer for stage 3 to complete because of media rewind and

searching operations that occur during this stage.
