Understanding the LEDs

LEDs during self-test
Your HP StorageWorks VS160 tape drive has four LEDs (light emitting diodes) on the front
panel, which indicate drive status. The desktop model also has a green Power LED. These
LEDs provide useful troubleshooting information.
The tape drive performs a power-on self-test whenever power is applied. The test takes
between 25 seconds (no cartridge loaded) and several minutes (cartridge loaded).
• The LEDs illuminate one at a time, from left to right, starting with the Ready LED, next the
Fault LED, and finally the Clean LED, at approximately one second intervals.
• The Media LED illuminates very briefly and then all the LEDS go off. The Ready LED then
blinks for 10 to 15 seconds.
• If a data cartridge is not loaded, the Ready LED illuminates and POST is complete, the entire
process taking approximately 25 seconds.
• If a data cartridge is loaded, the Ready LED flashes while the tape drive mounts the data
cartridge, a process that can take several minutes.
• As POST completes, the tape drive makes a slight buzzing noise for several seconds. This
noise is normal.
• The tape drive is now ready to use.
