Power-On Self-Test 13
The DLT-S4 tape drive system performs a self-diagnostic test, called a
Power-On Self-Test (POST) each time you turn on the tape drive (see
table 36
). This test helps in detecting problems with the tape drive.
POST completes in approximately 10 seconds. While POST is running,
the tape drive system responds
BUSY to SCSI commands, but will
respond to various SCSI messages.
During POST, the tape drive responds in the following ways.
It may take longer than the duration of POST for the tape drive to become
ready.
Eject Button N/A Press Use the
Eject button to eject the cartridge from the tape
drive. When you press the button, the tape drive
completes any active writing, then ejects the cartridge.

shipping. For instructions, see chapter 15, Preparing the
Tape Drive for Shipping.
See chapter 3, Cartridges
for detailed cartridge
handling procedures.
