The chassis is powered by a single internal universal power supply, eliminating the need for multiple power connections. Allied Telesyn also offers an optional hot swappable power supply to eliminate down time on the network. The unit saves space in the wiring closet and minimizes the number of power connections required. The single unit media converters can also be removed from the AT- CR12 and deployed individually in order to accommodate network change.

Whether using one or two power supplies, power is equally distributed between all media converters. This is accomplished by incorporating a backplane with 12 different power entry modules integrated with the printed circuit board.
