AC Power Supply Modules

The PS/AC/3K Power Supply module is an advanced-design, multi-output switching power
supply, providing AC primary input power configurations. The Power Supply modules are
located on the front panel and connect to the PEM modules (located on the rear panel)
through the chassis' backplane. The unit has a handle for easy removal and re-insertion,
under power (hot-swap capable).
Power for the device is typically supplied from redundant AC power feeds, whose input
voltage ranges from 100-240 VAC. The Power Supply modules function in an output
current, load-sharing configuration to provide necessary voltages and fail-safe operation to
the blades in the chassis.
