The WS-X4548-GB-RJ45V is a 48-port Gigabit Ethernet (10/100/1000) PoE line card designed for Cisco Catalyst 4500 series modular switches.
It provides high-density access switching with Power over Ethernet (PoE) for enterprise networks.
This module is a plug-in line card used inside Catalyst 4500 chassis such as:
- Catalyst 4506
- Catalyst 4507R / 4507R-E
- Catalyst 4510R
It delivers:
- 48 × RJ-45 Gigabit Ethernet ports
- IEEE 802.3af PoE support (power to IP phones, APs, cameras)
- Layer 2 / limited Layer 3 switching depending on supervisor engine
It is designed for enterprise campus access layers and PoE device-heavy deployments.
