2 slot chassis

D-Link’s redundant power supply (RPS) are designed to conform to the wattage requirements of D-Link’s Ethernet and Gigabit switches. They are external RPS units enclosed in solid metal cases with sockets to AC or DC power sources on one end, and connect to a switch’s internal power supply on the other end. They provide a low-cost, simple solution to the problem of an inadvertent failure of the internal power-supply of an Ethernet switch, which can result in the shutdown of that switch, the devices attached to its ports, or an entire network. Supporting full output power for the switch, this redundant power supply can maximize the power availability of the switching device.

– Power-supplies can be installed as stand-alone power supply units or mounted in 19-inch multi-slot chassis
– Power-supplies are hot swappable when installed in chassis
– Up to 589 watts output power
– Provide backup power for switch’s built-in power supply
