Understanding the LEDs

LEDs during self-test
Clean
Your Ultrium tape drive has four LEDs (light emitting diodes) on the front panel, which indicate
drive status. These LEDs provide useful troubleshooting information.
The tape drive performs a power on self-test whenever power is applied or the drive is reset.
The test takes about 5 seconds.
1 The green Ready light flashes several times and then remains on if self-test passes. All other
LEDs remain off.
2 If the self-test fails, the Drive and Tape LEDs flash, while the Ready and Clean LEDs are
off. This continues until the drive is reset.
