C8151H-C-G2 Description
The C8151H-C-G2 combines the two capabilities the 8100 Series otherwise keeps apart: a 10G BASE-T uplink and an embedded 5G modem. Its WAN side is a 1GE RJ-45/SFP combo port alongside the ten-gigabit copper port, the cellular path is a 3GPP Release 17 module with dual nano SIM slots soldered into the chassis rather than a pluggable, and six LAN ports plus two Flex ports serve the site. Cisco marks it SD-WAN Capable Yes with 900 Mbps of SD-WAN and 1 Gbps of Threat Protection alongside 5.6 Gbps forwarding, and the table tier is 500K routes with 4K VRFs. The fanless 5.1 lb body draws 25W typical and starts at Cisco IOS XE 26.1.3.

Product Performance
Key Features
No other 8100 model carries both a 10G BASE-T uplink and a cellular interface; the pluggable-radio models top out at gigabit WAN ports and the other ten-gigabit model has no cellular path at all.
The 5G module is built into the chassis with dual nano SIM slots rather than fitted as a pluggable, so the radio generation is fixed at purchase but no slot is consumed and no separate module line appears on the order.
Two nano SIM slots let the site hold profiles from two carriers, which is what allows a failover path that does not depend on a single operator’s coverage at that address.
Cisco lists twenty-five 5G FR1 bands and LTE bands from B1 through B106 on the embedded module, so the same SKU is deployable across regions without selecting a radio variant.
The ten-gigabit WAN port is matched by six gigabit LAN positions and two Flex ports, so the site can terminate a fast circuit and its wired devices on one chassis.
Typical draw is 25W on a 66W supply in a fanless body, so the embedded modem adds no fan, no second power feed and no separate mounting position.
Application Scenarios
Deployed where a ten-gigabit copper circuit is the primary path and the embedded 5G module provides backup without an external gateway.
Installed where two carrier SIM profiles are held in the chassis so the backup path can move between operators.
Placed in occupied rooms that have been upgraded to a fast copper circuit and cannot host equipment with fans.

Cisco IOS XE 26.1.3 |
Cisco IOS XE 26.1.3 |
Cisco IOS XE 26.1.1 |
- C8151H-C-G2 and C8130H-G2 share the 10G BASE-T uplink and the 26.1.3 software floor and diverge on everything the branch actually runs on. This model adds an embedded 5G module, four more LAN ports, SD-WAN capability with 900 Mbps published and the 500K route tier, and triples forwarding to 5.6 Gbps.
- The cost of that step is 1.6 lb and 3W of typical draw, both modest, so a ten-gigabit site with any cellular or fabric requirement has little reason to stay on the smaller model.
- C8151-CVAI-G2 carries the same embedded 5G module, the same six LAN ports and the same fabric capability, but its fast WAN interface is an XGSPON/10G BASE-T port paired with a DSL modem rather than a plain 10G BASE-T port, and it sits on the 26.1.1 train instead of 26.1.3.
- For deciding which SKU to order, confirm what the fast circuit is: a plain ten-gigabit copper handoff points here, while a DSL line or a passive optical service points to the C8151-C variants; then check whether cellular and fabric are needed, since dropping both makes C8130H-G2 the lighter option on the same software train.
Selection Guide
1. Where Ten Gigabits And Cellular Both Apply
This is the only 8100 model with both a 10G BASE-T uplink and a cellular interface; a fast-circuit site needing wireless failover cannot be built from C8130H-G2, which has no radio, or from C8151-G2, whose WAN ports stop at a gigabit.
2. An Embedded Modem Fixes The Radio Generation
C8151-G2 and C8161-G2 take a removable pluggable while this model’s 5G module is built in; an estate that expects to swap radio hardware later keeps that option only with the pluggable models, at the cost of the ten-gigabit port.
3. Two SIM Slots Against One Carrier Dependency
The dual nano SIM arrangement lets a site hold two operator profiles, which matters where a single carrier’s coverage at the address is uncertain; no single-SIM alternative in the series offers the same fallback.
4. When The Circuit Is DSL Or PON Instead
C8151-CVAI-G2 and C8151-CVAP-G2 carry the same embedded 5G and six LAN ports but replace the plain ten-gigabit port with an XGSPON/10G BASE-T port beside a DSL modem; a site on a broadband line needs one of those rather than this model.
5. The Latest Train In The Series
Cisco IOS XE 26.1.3 is required here and on C8130H-G2 alone, while the DSL models sit on 26.1.1 and the basic routers on 17.18.1; an estate mixing 8100 models has to carry three release families rather than one.
Ordering Checklist
|
Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Fast circuit type |
Confirm the handoff is a plain ten-gigabit copper circuit rather than DSL or a passive optical service. |
A DSL or PON site needs C8151-CVAI-G2 or C8151-CVAP-G2, which carry a different WAN arrangement. |
|
Cable category and run length |
Confirm the installed cabling supports 10GBASE-T over the required distance. |
Copper ten-gigabit is distance and category limited and no optical alternative exists on this port. |
|
Carrier SIM profiles |
Confirm which carrier profiles will occupy the two nano SIM slots. |
The module is embedded and the SIMs are the only per-site cellular decision. |
|
Cellular band coverage |
Confirm the deployment region falls inside the published 5G FR1 and LTE band list. |
The radio is fixed in the chassis and cannot be exchanged for a regional variant. |
|
Software image floor |
Confirm the image is Cisco IOS XE 26.1.3 or later. |
This model shares the latest 8100 floor with C8130H-G2 and will not run the 26.1.1 or 17.18.1 images. |
|
Combo port media |
Confirm whether the gigabit combo WAN port will use copper or an SFP optic. |
The cage accepts either but an optic is a separate line item. |
|
Mounting hardware |
Confirm which of rackmount, desktop, under-desk or DIN-rail mounting the site uses and that the accessory is on the order. |
Each mounting position needs its own hardware. |
