Cisco 300W Hot-Plug Redundant Power Supply for Catalyst 4948E

The Cisco PWR-C49E-300AC-F is a power supply for the Catalyst 4948E switch that supports hot plug replacement and redundancy, allowing you to maintain network uptime even during maintenance or unexpected power events.

This module delivers up to 300 watts of consistent power while accepting an AC input range of 100 to 240 volts, so it integrates smoothly into data centers, campus wiring closets, and branch offices around the world. An integrated Power Factor Correction circuit helps the switch draw power efficiently, which can reduce energy costs and minimize heat inside the rack.

Because it is hot pluggable, you can slide the unit in or out of the chassis without interrupting traffic. Pairing two of these modules in a redundant configuration gives the Catalyst 4948E an extra layer of protection: if one supply fails, the second one takes over automatically, keeping applications and services online.

Whether you are replacing a failed unit, adding redundancy to strengthen an existing installation, or stocking a spare for rapid recovery, the Cisco PWR-C49E-300AC-F offers a dependable way to safeguard network operations and business continuity.
