Quantum DLT VS80 manual Indicator Activity During Power-On Self-Test Post

Chapter 4: DLT VS80 Use

4.1.1Indicator Activity During Power-On Self-Test (POST)

Every time you power on 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.

1.The LEDs illuminate all at once and then turn off.

2.The Ready (green) LED blinks during initialization and remains illuminated after POST.

3.The tape drive emits a buzzing sound as it calibrates the read/write head’s position. POST is complete only after the buzzing sound stops.

POST takes sever seconds to complete, after which the tape drive is ready to use.

4.1.2Indicator Activity During Tape Drive Operation

When your tape drive is in use, a variety of indicator LEDs can blink or be illuminated. Table 4-1describes the circumstances under which one or more indicators are illuminated or blinking immediately after POST.
