The C3K-PWR-750WAC is a Cisco 750W AC power supply that fits Catalyst 3750-E and 3560-E switches (24-port and 48-port, with or without PoE) and the bays of the Cisco Redundant Power System 2300. In an RPS 2300, two supplies must be the same type. The spare-part number is C3K-PWR-750WAC=.
Maximum output is 750 W, with the 12 V rail rated at 25 A. AC input is 100 to 240 VAC at 50-60 Hz, drawing 10 to 5 A through an IEC 320-C13 receptacle, with a 15 A power cord rating and a minimum output holdup time of 20 ms. AC OK and PS OK LEDs show input and output status.
Installed in an RPS 2300, one C3K-PWR-750WAC delivers 252 W at 12 V DC and 416 W at -52 V DC. Two supplies deliver 540 W at 12 V DC and 832 W at -52 V DC. One supply backs up one switch, and two back up two switches, though a single 750W supply cannot back up a Catalyst 3750-E or 3560-E that runs a 1150W supply. The module measures 1.65 x 6.0 x 11.4 in. (4.2 x 15.24 x 28.96 cm) and weighs 3.9 lb (1.8 kg).
The 1150W C3K-PWR-1150WAC fits the same switches and the same bays, and the PWR-RPS2300 chassis runs on one or two supplies. More supplies are in Cisco Catalyst accessories.
