Cisco NIM-1GE-CU-SFP 1-Port Gigabit Ethernet WAN NIM — Dual-Mode RJ-45 or SFP, for ISR 4000, Refurbished
Warranty: Lifetime
One more gigabit WAN port for an ISR 4000 — copper or fiber, your choice
Cisco NIM-1GE-CU-SFP — 1-port Gigabit Ethernet WAN network interface module, dual-mode RJ-45/SFP
→ A WAN port, not a switch. This NIM adds one routed Gigabit Ethernet WAN interface. For extra LAN switch ports, see the NIM-ES2 switch modules.
Part Number: NIM-1GE-CU-SFP
SKU: NIM-1GE-CU-SFP-R
Description: 1-port Gigabit Ethernet WAN NIM, dual-mode RJ-45 and SFP
The NIM-1GE-CU-SFP adds one Gigabit Ethernet WAN port to a Cisco ISR 4000 router. The port is dual-mode: use the RJ-45 jack for copper or the SFP slot for fiber.
It is a common way to add a second internet circuit or a fiber hand-off without replacing the router.
