Chapter 2. Product Description 2-9
The library has a redundant power configuration that allows each unit to be
hot-swapped as required without interrupting library operation. Each power supply
in a library includes its own input AC line cord. Each supply carries one-half the
power load. If a line cord or power supply fails, the second supply sources the
complete power load, and a warning message is reported to the Operator Panel, Web
User Interface and to e-mail and SNMP notification recipients.
The library is powered ON when the power supply switch ( in Figure 2-10) on the
rear panel is ON; the library has no independent power switch on the front panel. The
power supply LED ( in Figure 2-10) on the rear panel also indicates when power is
turned ON.
The power system of the library contains the following components:
• Power supply
• AC power cord
