Tape Library Power Switch
Tape Library Power Switch
The tape library power switch is a circuit breaker or breakers behind the right front door
of the tape library.
Figure 4-13 shows the power switch location. This switch, attached
to the AC power distribution unit (PDU), controls the AC power to the tape library and
tape drive column.
The power switch has two configurations:
•
A single breaker on the AC power distribution unit controls the tape library and a
single tape drive column.
•
An optional second breaker, located on the second power distribution unit power
and the second drive column, and an optional second library power supply.
To apply power to the library and drive column, lift the switch or switches.
To remove power from the library and drive column:
1. Make sure all jobs are complete.
2. Push down on the library power switch or switches.
Note.
1. For this configuration, the second breaker must be connected to a separate electrical circuit.
2. If only one breaker is powered off, the second breaker, if installed, will still be powered on.
