4.1.1 Interpreting the Indicators
This section describes what each front panel indicator means and the circumstances under which one
or more indicators are illuminated.
Indicator Activity During Power-On Self-Test (POST)
Every time you power on or reset your tape drive, it conducts a power-on self-test (POST). This test
ensures that your tape drive is working properly and is ready to use. While POST is in progress, watch
the front panel LEDs to see the progress and results of the test:
•
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.
•
About four seconds later, the Media LED illuminates.
•
Each LED signals a different part of the POST process.
•
All LEDs then blink momentarily.
•
If a data cartridge is not loaded, the Ready LED illuminates and POST is complete, the entire
process taking approximately eight 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.
Indicator Activity During Normal Operation: Ready LED
When your DLT VS160 tape drive is in use, the Ready LED indicates the three states detailed in
Table 4-1 . The Ready LED operates independently of the other three LEDs.
