Operator panel
The operator panel is located on the front of the control module and consists of the indicator panel
and the OCP (see
Figure 8 (page 23) ). In the indicator panel, the buttons are for robot control and
power, and the indicators provide library status.

The OCP is the library navigation point and provides access to the LMC. For more information
about the OCP and the LMC, see
“Accessing the Library Management Console (LMC)” (page 80) .
Power system
The library supports single and redundant power configurations. The single configuration has a
single AC line input and single DC power supply. The redundant configuration has dual AC line
input and dual DC power supplies. You can hot swap a power supply if you have a redundant
power supply. You can hot add a second power supply.
The power system consists of the following:
•
Power supply
•
Power distribution unit (PDU)
•
AC power cord
A single power switch, located on the access door, turns on and off all power for the control module
and attached standard or high density expansion modules. Each PDU has a second circuit breaker,
located in the rear of the module, that controls the module power supply output. The power supply
has three LEDs that provide status information. The power system also has four fuses for system
protection.
Using the library demonstration mode
By running the library in demonstration (demo) mode, you can demonstrate the ability of the library
to move scratch media from an I/E station to a randomly selected storage slot, and then move
media from storage slot to open storage slot until you pause or stop the demonstration.
Non-demonstration media in the storage racks are not affected by the demonstration. While the
demonstration proceeds, graphs on the main LMC display show data transfer and mount statistics
using data that the demonstration routine provides. Demo mode is available only from the library
OCP.
