Note – 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 FIGURE 1-2) 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.
