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