The indicators on the right front panel turn on sequentially from
top to bottom. All indicators stay on for a few seconds.
All indicators on the left front panel turn on at the same time for
about three seconds and then turn off.
The green Operate Handle, the orange Write Protected, and the
yellow Use Cleaning Tape indicators turn off. The yellow Tape
in Use indicator blinks while the tape drive initializes.
After initialization, if no cartridge is loaded, the yellow Tape In
Use indicator turns off, the green Operate Handle indicator turns
on, the handle unlatches, and the beeper sounds.
For more information on what happens after initialization when a
cartridge is present, and the handle is either down or up (not
recommended), see Chapter 4, Section 4.5.4.
POST completes in about 13 seconds, and the drive responds
normally to all commands; however, it might take longer for the
media to become ready. After a bus resets, the tape drive responds
within a bus selection time-out period.
