The WS-X4548-GB-RJ45 is a 48-port Gigabit Ethernet (10/100/1000) modular line card used in Cisco Catalyst 4500 series chassis switches.
It is a high-density access layer module designed for enterprise networks and campus deployments.
This is a plug-in switch line card, not a standalone switch. It only works inside a Catalyst 4500 chassis together with a Supervisor Engine.
It provides:
- 48 × RJ-45 Gigabit Ethernet ports (10/100/1000 Mbps)
- Enterprise access-layer connectivity for end devices
- Support for PoE depending on chassis and power configuration
- Integration into Cisco’s centralized switching architecture
