Cisco Catalyst 4500E 48-port s 12p mGig & 36x 10/100/1000 UPoE line card

The Cisco Catalyst 4500E 48-Port line card (WSX474812X48U+E) delivers high-density 10/100/1000BASE-T connectivity with 12 mGig ports and 36 standard Gigabit Ethernet ports, all supporting Cisco Universal Power Over Ethernet Plus (UPoE+) for up to 60W per port. Designed for the Catalyst 4500E Series chassis, this modular line card enables seamless network expansion and PoE++ capabilities for advanced devices such as wireless access points, IP cameras, and IoT endpoints.

Advantages

Maximize your network investment with this hot-swappable line card that offers a total PoE budget of up to 1800W per slot (dependent on chassis and power supply). With a forwarding rate of 48 Mpps and switching capacity up to 240 Gbps per slot, it ensures high-performance data handling. The 12 mGig ports provide flexible multi-gigabit speeds (100M/1G/2.5G/5G/10G) for next-generation Wi-Fi 6/6E access points, while the 36 10/100/1000 ports support legacy devices. Jumbo frame support up to 9216 bytes and 8 queues per port enhance traffic management.

Suitable for

• Enterprise campus networks requiring high-density PoE++ for IoT and wireless
• Upgrading existing Catalyst 4500E chassis to support UPoE+ and mGig
• Deployments with mixed-speed endpoints (1G to 10G) needing unified switching
