Understanding the LEDs
LEDs during self-test
Your Ultrium tape drive has four LEDs (light emitting diodes) on the front panel, which indicate
drive status, and two LEDs on the rear panel. 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. The LED sequence for each drive is described in the following
table.

Note The LED labels are identical apart from the bottom one, which is Clean on the Ultrium 960
and 460 and Use Cleaning Cartridge on the Ultrium 230. All references to Clean in the
following table should, therefore, read Use Cleaning Cartridge if you have an Ultrium 230
drive.

until the drive is reset.
