NIM-1GE-CU-SFP Description
NIM-1GE-CU-SFP is a Cisco 1-port Gigabit Ethernet WAN Network Interface Module for Cisco 4000 Series ISR routing platforms. It provides one dual-mode GE/SFP WAN port that can use RJ-45 copper or SFP media, routed Layer 3 operation, no onboard Layer 2 switching, no Power over Ethernet, NIM form factor, support across Cisco 4000 Series ISRs, and hard online insertion and removal support. The module adds one media-flexible routed Gigabit Ethernet WAN interface to a branch ISR.

Application Scenarios
Select NIM-1GE-CU-SFP when a Cisco 4000 Series ISR needs one added routed Gigabit Ethernet WAN interface and the site has not standardized on a two-port or SM-X module.
Use this SKU when the circuit handoff may be built as RJ-45 copper or SFP fiber, but the router bill should stay within one dual-mode GE/SFP NIM position.
Deploy NIM-1GE-CU-SFP for Layer 3 WAN termination where the host router routes traffic from the module and the design does not require on-module Layer 2 switching or PoE.

SM-X-6X1G (=) |
SM-X-4X1G-1X10G (=) |
- In a NIM-1GE-CU-SFP vs NIM-2GE-CU-SFP comparison, the table-backed difference is port count and MACsec: NIM-1GE-CU-SFP is the one-port module without MACsec, while NIM-2GE-CU-SFP is the two-port NIM with 256-bit MACsec.
- The NIM-1GE-CU-SFP difference from SM-X-6X1G is form factor and density; NIM-1GE-CU-SFP uses one NIM slot, while SM-X-6X1G uses an SM-X slot for six routed Gigabit Ethernet ports.
- For buyers comparing NIM-1GE-CU-SFP vs SM-X-4X1G-1X10G, the comparison should start with slot type and speed mode because SM-X-4X1G-1X10G can be ordered for four GE ports or one 10G SFP+ port.
- The which model to choose review should keep NIM-1GE-CU-SFP on the order only when one routed GE/SFP WAN port is enough and the router has the correct NIM or adapter placement.
Selection Guide
1. Choose it for one routed GE/SFP WAN port
Select NIM-1GE-CU-SFP when the Cisco 4000 ISR order needs a single routed Gigabit Ethernet handoff with RJ-45 or SFP media flexibility.
2. Move to NIM-2GE-CU-SFP for two ports or MACsec
Use NIM-2GE-CU-SFP instead when the platform supports it and the bill needs two dual-mode GE/SFP WAN ports or Cisco-documented 256-bit MACsec.
3. Reserve SM-X choices for higher-density slot plans
Move to SM-X-6X1G only when an SM-X slot is available and six GE routed ports are required; review SM-X-4X1G-1X10G when the design needs the documented 4x1G or 1x10G operating choice.
4. Verify media and software before releasing the order
Confirm the Cisco 4000 Series ISR support row, platform software reference, RJ-45 or SFP handoff, and no-PoE boundary because those items control whether this one-port NIM matches the deployment.
Ordering Checklist
|
Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Host router |
Cisco 4000 Series ISR with an available NIM slot or supported adapter placement |
The module is a NIM and should not be treated as a standalone switch or Catalyst 8000 C-NIM part |
|
Media handoff |
RJ-45 copper or SFP for the single dual-mode GE/SFP port |
Keeps the optics or cabling plan aligned with the circuit handoff |
|
Port role |
Routed Layer 3 WAN port with no on-module Layer 2 switching |
Avoids ordering it for local LAN switching between router ports |
|
Power plan |
No PoE support on Cisco Gigabit Ethernet WAN Modules |
Prevents using this SKU for a powered endpoint requirement |
|
Security requirement |
No MACsec support on NIM-1GE-CU-SFP |
Moves MACsec projects toward a Cisco-listed alternative such as NIM-2GE-CU-SFP when the platform supports it |
