Cisco 650W AC Hot-Plug Redundant Power Supply

The Cisco C9K-PWR-650WAC-R= is a 650 watt AC power supply module designed for Catalyst 9500 Series switches. It provides the clean, stable power that enterprise networks rely on while reaching an efficiency rating of 94 percent, which helps lower operating costs and reduce heat inside the rack.

The module installs from the rear of the switch and locks in place without tools, allowing a technician to add or replace it while the equipment stays online. When a second identical supply is present, the two operate in a redundant configuration, so one unit can fail or be removed for maintenance without interrupting network traffic. This hot-plug capability is valuable in campus cores, branch offices, and top of rack deployments where downtime is unacceptable.

A wide 90 to 264 volt AC input range and an IEC 60320 C14 connector make the supply compatible with standard power outlets found worldwide. With 650 watts of output, it easily supports Catalyst 9500 models such as C9500-24Y4C-10A and C9500-48Y4C-10E, meeting their demands for both switching performance and PoE budgets when applicable.

For network administrators who want predictable maintenance and quick recovery times, the plug in design keeps mean time to repair to a minimum. Simply slide out a failed unit, insert a replacement, and the switch continues to run without service disruption.
