1. Ensure that there is no cassette tape in the drive.
2. Power on the 10/20-GB DLT Cartridge Tape Drive device, either by cycling the pedestal
subsystem power switch off and on or, if other SBB units in that subsystem are active
and should not be powered down, by hot-swapping the SBB unit under test (i.e., pull it
free from the pedestal and then slide it back into its operating position).
3. Observe that all left-side panel indicators initially light, with all right-side indicators then
lighting sequentially, from top to bottom.
4. If the SCSI bus is not connected, all left-side panel indicators will stay lit; if the SCSI
bus is connected, all left-side panel indicators should go out within 1 second after power
is applied, while all right-side panel indicators should remain lighted for 3 to 5 seconds
and then go out, except for the T
APE IN
U
SE
indicator, which should continue to blink for
a few seconds while tape mechanism searches for tape and then go out, at which time an
internal beeper sounds to alert the operator and the green O
PERATE
H
ANDLE
indicator
becomes steadily lit to indicate that door latch is released and that the cartridge in-
sert/release handle can be pulled up to allow insertion of tape.
