Power Supply Module
The device can be powered from an AC or a DC power source. The type of power depends on
your ordered hardware configuration.
AC Power Supply Module
For the AC-powered model, the device provides two AC Power Supply modules for load
sharing and power redundancy. The power source is a standard electrical outlet providing AC
power.
Power surge protection, caused for example from lightning, is also supported. For more
information, see
Grounding and Surge Protection
The Power Supply module is available as a spare part. The Power Supply modules are hot-
swappable and therefore, if only one needs to be replaced, it can be done while the device is
receiving power from the working Power Supply module. For replacing Power Supply modules,
see
