State LED Display and Activity
A tape cartridge is present and
the handle is down. The tape drive loads the medium from the cartridge. The
Tape In Use LED stops blinking and remains on. The LED next
to the tape’s actual density is on. When the Density Override
LED blinks, a density may be selected. The tape drive is ready
for use and the media is positioned at BOT.
No tape cartridge present. The Tape in Use LED = Off. The Operate Handle LED = On.
Insert/Release Handle is unlatched. Tape drive beeper sounds
tone to signal that the handle may be raised and a tape
cartridge inserted.
A tape cartridge is present, but
the handle is up (not
recommended). The Tape In Use LED = Off. The Operate Handle LED flashes.
When the Insert/Release Handle is lowered, the cartridge
loads. If handle will not lower, ensure the tape cartridge is
pushed all the way into the tape drive.
The tape drive detects an error
condition. Right- or left-hand LED’s blink repeatedly. Try to unload the
tape and reinitialize the tape drive by pressing the Unload
button or turn the drive power off then back on. The LED’s
stop blinking and the drive attempts to reinitialize. Note that
after pressing the Unload button you may have to wait five
minutes before the Operate Handle LED lights due to the
retry. The LED’s light steadily, then turn off if the test
succeeds.
The drive is powered on with
the handle in open position. Operate Handle LED is blinking. Close the Insert/Release
Handle and wait for LED to light steadily.
