Cisco 1150W Hot-Plug Power Supply for Catalyst Series

The Cisco C3K-PWR-1150WAC is a hot-plug power supply that delivers 1150 watts to Catalyst 3560E, 3560V2, and 3750E switches, as well as to the Redundant Power System 2300. It slides directly into the chassis, allowing installation or replacement while the network stays online.

Because it supports hot swap operation, network administrators can replace a failing unit or add extra capacity without scheduling downtime or disrupting users. This ability is valuable in offices, branch locations, and data closets where switches carry voice, video, and critical data traffic throughout the workday.

The 1150 watt capacity provides the overhead needed for switches running at full port density or supplying Power over Ethernet to numerous devices. Consistent voltage delivery, backed by Cisco engineering, helps maintain stable network performance during demanding workloads.

Whether you are building a redundant power configuration or keeping a spare on hand for rapid replacement, this module integrates naturally into existing Cisco Catalyst environments and helps keep essential services running without interruption.

Highlights:

• Delivers up to 1150 watts of power
• Hot-plug module installs or removes without powering down the switch
• Compatible with Cisco Catalyst 3560E, 3560V2, and 3750E switches
• Also works with the Cisco Redundant Power System 2300
• Fits seamlessly into existing Catalyst deployments
