Overview
The AT-WDRPS-80 is a DC Redundant Power Supply (RPS) for the AT-WD1008
Multiplexer chassis. When installed, the unit shares the load of powering the
chassis with the standard power supply that comes pre-installed in the chassis. If a
power supply fails, the remaining unit provides all power to the system, thereby
preventing a network failure. The power supply is hot-swappable, meaning that
you can install it while the chassis is powered ON.
