Crestron CEN-SWSFP-PWS350 350 W Switch Power Supply Module

A modular switch has an empty bay for a reason. The CEN-SWSFP-PWS350 fills it on a CEN-SWSFP-28 or a CEN-SWPOE-52-ULTRA, adding up to 350 W of output from a 110-240VAC input.

It does two jobs depending on how the switch is configured. Fitted alongside the internal supply it expands the PoE budget available to the switch's powered ports, which is what lets a 52-port Ultra switch actually deliver 90 W on more than a handful of them. Fitted as a spare it provides redundancy, so a failure in the main switch power circuit does not take the network segment down. It hot-fits into the switch's own bay, so no rack space or outlet is consumed beyond the mains lead.
