Cisco NIM-2GE-CU-SFP=

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.

• Compatibility: Cisco 4000 Series Integrated Services Routers, including 4451-X
• Layer 3 routed interfaces for WAN and inter-VLAN routing
• Operating temperature: 32 °F to 104 °F (0 °C to 40 °C)
• Dimensions: 1.3 in × 3.5 in × 7.2 in (3.3 cm × 8.9 cm × 18.3 cm)

Connectivity and compatibility

This module offers a versatile mix of copper and fiber connectivity options, making it adaptable to various network topologies. The copper RJ-45 ports are ideal for short-distance connections to servers or access switches, while the SFP slots accommodate fiber transceivers for longer runs to aggregation switches or service provider equipment. It integrates seamlessly with Cisco 4000 Series routers, ensuring consistent management and performance across your network infrastructure.

Ideal uses and environments

The NIM-2GE-CU-SFP= module is well suited for branch offices and campus edge locations where additional Gigabit Ethernet ports are required without adding separate switches. It supports network growth by allowing a flexible combination of copper and fiber connections, which helps maintain straightforward wiring and efficient use of rack space. Its reliable operation within standard temperature ranges makes it a strong choice for climate-controlled data centers and wiring closets.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
