C-NIM-1M Description
C-NIM-1M is a Cisco Catalyst 8000 Series 1-port mGig RJ-45 WAN Network Interface Module for expanding Catalyst 8200, Catalyst 8200L, and Catalyst 8300 edge platforms with a copper WAN handoff. The module uses the NIM form factor, provides one RJ-45 copper port with 100/1000/2500BASE-T support, delivers Cisco UPOE+ 802.3bt power up to 90W on the port, is listed with a 17.6.1 minimum Cisco IOS XE software requirement, and is not supported for WAN MACsec on C-NIM-1M.

Application Scenarios
Use C-NIM-1M when a Catalyst 8200, Catalyst 8200L, or Catalyst 8300 router needs one routed RJ-45 WAN port that can run at 100 Mbps, 1 Gbps, or 2.5 Gbps.
Select this SKU when the design needs a Cisco UPOE+ 90W source from the host router for an attached cellular gateway.
Deploy C-NIM-1M through C-SM-NIM-ADPT when a Catalyst 8300 chassis uses an SM-X carrier adapter to increase supported NIM positions and the service window requires full online insertion and removal for the adapter path.

- In a C-NIM-1M vs C-NIM-2T comparison, the table-backed difference is port role: C-NIM-1M provides one 100/1000/2500BASE-T RJ-45 port with UPOE+, while C-NIM-2T provides two dual-mode GE/SFP WAN port groups without listed PoE.
- The C-NIM-1M difference from C-NIM-1X is media and speed focus; C-NIM-1M is the copper mGig UPOE+ option, while C-NIM-1X is the 1G or 10G SFP+ WAN option with 256-bit WAN MACsec.
- For buyers comparing C-NIM-1M vs C-NIM-2T or C-NIM-1X, the model to choose depends on whether the BOM needs 2.5G RJ-45 with 90W power delivery, dual 1G RJ-45/SFP flexibility, or 10G SFP+ WAN connectivity.
Selection Guide
1. Choose it for one powered mGig copper WAN port
Select C-NIM-1M when the router bill needs a single 100/1000/2500BASE-T RJ-45 WAN port and the attached device plan requires Cisco UPOE+ up to 90W.
2. Move to C-NIM-2T for dual 1G media flexibility
Use C-NIM-2T instead when the order needs two WAN port groups with RJ-45 or SFP 1G choices and does not require the C-NIM-1M UPOE+ function.
3. Use C-NIM-1X when 10G SFP+ or WAN MACsec is required
Select C-NIM-1X only for Catalyst 8300 designs that need 1G or 10G SFP+ WAN connectivity and 256-bit WAN MACsec instead of mGig copper PoE.
4. Verify software and power before release
Check Cisco IOS XE 17.6.1 or later support context, the host Catalyst platform, PoE power supply design, and any C-SM-NIM-ADPT placement before approving the hardware quote.

|
PoE standard |
IEEE 802.3bt UPOE+ |
Match the powered endpoint requirement to the Cisco-supported PoE standard |

PoE power |
90W x 1 |
Keep the cellular gateway power plan within the single-port 90W scope documented for this module |
|
PoE voltage |
Nominal -54V with -53V to -55.8V range |
Align the host power plan with Cisco’s documented PoE voltage range |
|
Host power plan |
Catalyst 8300 PoE adapter support depends on chassis model |
Confirm the exact chassis and power supply configuration before ordering the powered WAN design |
Ordering Checklist

Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Exact SKU |
C-NIM-1M |
Confirms the order is for the single-port mGig RJ-45 UPOE+ WAN NIM |
|
Host platform |
Catalyst 8200 Series, Catalyst 8200L, or Catalyst 8300 Series |
Cisco documents this module for these Catalyst 8000 edge platforms |
|
Port requirement |
One 100/1000/2500BASE-T RJ-45 copper WAN port |
Separates C-NIM-1M from SFP based or dual-port C-NIM alternatives |
|
PoE requirement |
IEEE 802.3bt UPOE+ up to 90W on one port |
Prevents ordering a non-PoE WAN module for a powered endpoint plan |
|
Software baseline |
Cisco IOS XE 17.6.1 or later support context |
Matches Cisco’s documented minimum software version for C-NIM-1M |
|
MACsec need |
C-NIM-1M does not support WAN MACsec |
Keeps MACsec designs pointed to C-NIM-1X or C-NIM-2T where Cisco lists 256-bit WAN MACsec |
|
Adapter placement |
Direct NIM slot or C-SM-NIM-ADPT carrier adapter path |
Affects slot planning and the expected insertion or removal service procedure |
