This is the highest-rated AC power supply module for the Catalyst 3750-X and 3560-X switch families, also listed as PWR-C1-1100WAC. It is rated at 1100 W and accepts 115 to 240 VAC, autoranging, at 50 to 60 Hz and 12 to 6 A. The output is -56 V at up to 19.64 A.
The module weighs 3 lb (1.4 kg) and measures 1.38 x 11.72 x 3.25 in (3.5 x 29.8 x 8.3 cm) before the cord retainer, which adds 1.55 in (3.9 cm). Once installed it extends 1.5 in (3.8 cm) past the rear panel of the switch. The North American cord for it is a 16-AWG type.
The supply is hot-swappable, but in full PoE+ or power-sharing mode, pulling one can shut down powered devices until the power budget fits a single supply. Both supply slots must hold a module or a blank cover, and the open slot should not stay empty for more than 90 seconds while the switch runs. Two AC modules, two DC modules, one of each, or a single module with a blank cover are all valid combinations. After installation, the AC OK and PS OK LEDs should be green. The spare is ordered as C3KX-PWR-1100WAC=.
The 715W AC power supply is the sibling for the same bays. Cisco modules covers further modules.
