Controls and Indicators

This section describes the controls and indicators that you can use to monitor 

and troubleshoot the library. For tape drive controls and indicators, refer to the vendor 

publications and Web sites. For details on the Local Operator Panel, see the SL500 Local 

Operator Panel Guide, p/n 96258. 

Power Switch

When the switch (see 

) is in the On position (1

) 

the library and tape drives 

are powered-on. When the switch is in the Off position (0), the library and tape drives 

are powered-off.

Earlier built libraries had power supplies that had individual power switches. 

Later libraries have one power switch that controls all power supplies in the rack.
