The Cisco C3KX-PWR-350WAC is a 350-watt modular AC power supply for the Catalyst 3750-X and 3560-X Series switches. It is the default supply for the 24- and 48-port data (non-PoE) models and installs in either of the switch's two power-supply bays, so a second unit can be added for dual-redundant (1+1) operation. As a data-only supply it provides no Power over Ethernet budget.

Key features
