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 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.
