Home Networking Power Cisco PWR-C49-300DC-F/2 300W DC Power Supply for Catalyst 4948E-F

Cisco PWR-C49-300DC-F/2 300W DC Power Supply for Catalyst 4948E-F

Brand:
Cisco

Cisco PWR-C49-300DC-F/2 is a 300W DC power supply designed for the Catalyst 4948E-F switch. It provides front-exhaust cooling and supports redundant power configurations for compatible network deployments.

OVERVIEW

  • The Cisco PWR-C49-300DC-F/2 is a 300W DC power supply intended for the Cisco Catalyst 4948E-F Ethernet Switch. Cisco identifies this part as a front-exhaust DC power supply with redundant power capability.
  • Its DC power architecture and front-exhaust airflow make it relevant for network environments using compatible Catalyst 4948E-F equipment. The module is also described in available technical listings as hot-swappable, supporting serviceability where the installed system configuration permits power-supply replacement without taking the complete switching platform offline.
  • For procurement teams, network administrators, and IT resellers, the exact SKU is important because Cisco has multiple 300W AC and DC power-supply variants for the Catalyst 4948/4948E family.

USE CASES

  • Replacement power supply for compatible Cisco Catalyst 4948E-F deployments.
  • DC-powered enterprise network infrastructure requiring a 300W power module.
  • Redundant power configurations where a second compatible supply is required.
  • Data-center and network-room installations using front-exhaust airflow.
  • Maintenance and spare-parts inventory for legacy Cisco Catalyst switching infrastructure.
  • B2B IT hardware refurbishment, lifecycle support, and network equipment replacement programs.

KEY FEATURES

  • Cisco part number: PWR-C49-300DC-F/2
  • 300W DC power output
  • Designed for Catalyst 4948E-F platforms
  • Front-exhaust airflow design
  • Redundant power-supply configuration
  • DC terminal-block connection
  • Hot-swappable design as listed for this power-supply model
  • Suitable for compatible enterprise and network infrastructure environments
  • Exact Cisco SKU identification for procurement and replacement sourcing
