Power Off the Library

There are two methods of powering off the library: controlled and forced.

• Controlled Power-Down from the Interface — Always recommended, if possible.
• Forced Power-Down — Cuts power at the library or rack. Use this method only when the controlled method does not work.

Controlled Power-Down from the Interface

Always use the remote interface to power down the library when possible.

1. Stop any host activity.
2. From the remote interface, click the power button in the upper-left, and then select Power Down Library.
3. Optionally, select Prepare the Robot for removal before the library powers down This parks the robot at the top of the library. Select this option if you are powering down for any of the following reasons:

   • Removing or replacing the robot.

   • Moving the rack or moving the library to a new rack.

   • Preparing the library for shipment.

   If you selected "Prepare the Robot for removal", you must lock the robot (see Lock the Robot).

Forced Power-Down

Use the forced power-down method only if the controlled power-down did not work.

1. Stop any host activity.
2. Remove power from the library using one of the following methods:
   1. Press the front panel power button and hold it until the library shuts down (approximately 10 seconds).
   2. Remove power from all power supplies (disconnect the power cord from all power supplies or set the PDU or power strip switch to the off position).
