NETGEAR APS600W 600W Modular Power Supply Unit for M4300-16X and M4300-96X

The M4300-96X is a twelve-slot chassis that gets filled with copper, SFP+ and 40G port cards, and the M4300-16X is the fixed 10G box beside it. Both take the APS600W as their supply module, up to 600W at 110/220V AC through a C14 inlet. Populate a 96X with high-count port cards and the power draw climbs with every slot, which is exactly why the supply is a separate part rather than something soldered into the chassis.

A second unit in the spare bay gives the switch a redundant feed, and on a core that carries a whole facility's video that is not an optional extra. AC input runs 90 - 132V at 8A or 180 - 264V at 4A, and the DC rail is +54.5V at 11A. Both the module and the port cards are hot-swappable, so a supply is replaced without taking the chassis out of service.
