3.2.1 AC Power Switch
A power switch located on the rear panel controls ac power to the drive.
The switch is labeled with a 1 to indicate on and a 0 for off. When this
switch is on, ac power is connected to the power supply in the tape drive.
This switch must be on for the drive to operate. When this switch is first
set to 1, the TSZ07 goes through a self test as follows:
CAUTION
An abnormal interruption to system operation can occur
if the ac power switch is set to off (0) while the host
system is running. Always shut down the host system
before turning off the tape drive.
