D-Link 140W Redundant Power Supply

The DPS-200A, DPS-500A and DPS-500DC are modular redundant power supplies which can be installed as independent power supply units or placed inside a DPS-800 Rack-mount chassis. The chasses are designed for mounting in a standard 19-inch equipment rack. Multiple power supplies can be placed inside a chassis, from which they can connect to the switches mounted in the same rack.
