C-NIM-2T Description

The C-NIM-2T is a Cisco Catalyst 8000 two-port 100M/1G dual-mode GE/SFP WAN network interface module for branch routers that hand off copper and fiber circuits. It provides two RJ-45/SFP port groups with one port per group in use at a time, 100/1000BASE-T copper or 1000BASE-X SFP fiber, no PoE, and 256-bit WAN MACsec. The module installs in the NIM slot of Catalyst 8200, 8200L and 8300 routers and requires Cisco IOS XE 17.6.1.

Application Scenarios

Mixed-Media Branch Handoff

A branch with a Catalyst 8200 router can take one carrier circuit as copper and another as SFP fiber, terminating each on its own RJ-45/SFP port group at 100 Mbps or 1 Gbps.

Ports Behind An SM-X Carrier

On a Catalyst 8300, the module can sit in one of the two NIM positions of a C-SM-NIM-ADPT carrier, adding Ethernet WAN ports with 256-bit MACsec to the router.

C-NIM-2T and C-NIM-1X differ in speed and host support: C-NIM-2T has two dual-mode 100 Mbps/1 Gbps RJ-45/SFP groups and runs in Catalyst 8200, Catalyst 8200L and Catalyst 8300 routers, while C-NIM-1X has one 1G/10G SFP/SFP+ port and is documented for Catalyst 8300 only. A 10G SFP+ WAN circuit therefore needs C-NIM-1X, and Catalyst 8200 and 8200L sites cannot use it. One 2.5 Gbps copper WAN port, or 90W PoE for a powered device, points to C-NIM-1M, which runs in the same hosts as C-NIM-2T but is the only one of the three without 256-bit WAN MACsec.

Ordering Checklist

  • Catalyst 8200 hosts: Use C8200-1N-4T or C8200L-1N-4T, which have one NIM slot each. The module takes the router’s only NIM slot, which otherwise holds C8200-NIM-BLANK.
  • Catalyst 8300 hosts: Use a Catalyst 8300 1RU router such as C8300-1N1S-6T or C8300-1N1S-4T2X, which has a NIM slot. Catalyst 8300 routers list C-NIM-2T as a supported Layer 3 Ethernet NIM for the NIM slot.

Questions & Answers

  • Can C-NIM-2T carry one copper and one fiber WAN circuit at the same time?

    Yes. C-NIM-2T has two RJ-45/SFP port groups, and one port per group is active at a time. One group can run 100/1000BASE-T copper while the other runs a 1000BASE-X SFP, each at 100 Mbps or 1 Gbps, so one module can serve a copper carrier handoff and a fiber carrier handoff together at a branch.
  • Does C-NIM-2T fit the only NIM slot on C8200-1N-4T?

    Yes. C-NIM-2T takes the single NIM slot of C8200-1N-4T or C8200L-1N-4T, which otherwise holds C8200-NIM-BLANK. The router must run Cisco IOS XE 17.6.1 or later, and no carrier adapter is involved because Catalyst 8200 hosts take the module in the NIM slot only.
  • Can C-NIM-2T be installed in a C-SM-NIM-ADPT carrier on a Catalyst 8300?

    Yes. On a Catalyst 8300, C-NIM-2T sits in one of the two NIM positions of a C-SM-NIM-ADPT carrier. It keeps its two RJ-45/SFP port groups and 256-bit WAN MACsec there, and the second NIM position of the carrier stays free for another supported module.
  • Does C-NIM-2T supply PoE on its RJ-45 ports?

    No. C-NIM-2T has no PoE on either RJ-45/SFP port group. A powered endpoint needs a separate injector or a PoE-capable port elsewhere. The module runs at 100 Mbps or 1 Gbps and requires Cisco IOS XE 17.6.1, so any powered device at the site has to be fed from elsewhere.
