Cisco 2-Port SFP Gigabit WAN Module for 4451-X Router

Overview

The Cisco NIM-2GE-CU-SFP= is a network interface module designed to expand the connectivity options of the Cisco 4451-X Integrated Services Router. It provides two copper RJ-45 Gigabit Ethernet ports alongside two open SFP slots, allowing for flexible use of both twisted-pair and fiber cabling. This module supports Layer 3 routed interfaces, enabling secure WAN links and inter-VLAN routing without burdening the router’s built-in switch ports.

Installation is straightforward, with automatic detection by IOS XE, making it easy to integrate into existing Cisco 4000 Series ISR setups. Its compact design and reliable operation make it suitable for branch offices, campus edges, and small data centers where additional Gigabit Ethernet ports are needed.

Key features

• Two copper RJ-45 ports provide reliable 1000Base-T connections for nearby servers or switches.
• Two SFP slots support 1000Base-X fiber or copper transceivers, enabling longer distance uplinks and flexible media choices.
• Layer 3 routed port functionality allows for WAN access and inter-VLAN routing directly on the module.
• Plug-and-play installation with automatic IOS XE recognition simplifies deployment and configuration.
• Compact form factor fits easily into the NIM bay of Cisco 4000 Series routers without requiring additional hardware.
• Designed to operate within a temperature range of 32 °F to 104 °F, ensuring dependable performance in typical data center and wiring closet environments.
