Cisco

Cisco 4900M WS-X4920-GB-RJ45 20-Port Gigabit Ethernet RJ45 module card, supplied without fan and power supply, for modular network switching applications.

OVERVIEW

The Cisco WS-X4920-GB-RJ45 is a 20-port Gigabit Ethernet RJ45 module designed for the Cisco 4900M modular switching platform. It provides copper-based Gigabit Ethernet connectivity for enterprise network environments requiring additional interface capacity.
This module is supplied as a module card only, without fan and power supply, making it suitable for replacement, expansion, refurbishment, or configuration-specific deployment where compatible system components are already available.
For B2B buyers, the product is relevant to enterprise networking, infrastructure maintenance, data-center connectivity, network expansion, and Cisco 4900M platform lifecycle requirements.

USE CASES

Enterprise network expansion – Add Gigabit Ethernet copper connectivity to compatible Cisco 4900M deployments.
Hardware replacement – Replace an existing or failed compatible module in an established network environment.
Network refurbishment – Support infrastructure refresh and hardware reuse projects.
Infrastructure maintenance – Maintain installed Cisco modular switching systems with compatible interface hardware.
