Overview of Cisco C1111X-8P
The Cisco C1111X-8P is a ruggedized industrial router engineered to deliver high-density Power over Ethernet (PoE) and reliable connectivity in extreme environments. Part of the Cisco IR1100 series, it features 8x PoE+ ports, dual LTE Advanced Pro cellular modems, and Cisco IOS-XE software for secure, scalable IoT deployments. Designed for industries like manufacturing, utilities, and transportation, it operates in temperatures from -40°C to 75°C and meets MIL-STD-810G shock/vibration standards.
Key Technical Specifications and Industrial Applications
Hardware and performance highlights:
- PoE+ capacity: 30W per port (240W total), supporting energy-intensive devices like PTZ cameras, Wi-Fi 6 APs, and industrial sensors.
- Dual LTE redundancy: CAT-18 modems with carrier aggregation ensure failover during primary WAN outages.
- Security: Integrated with Cisco SD-WAN and Cisco Cyber Vision for encrypted traffic segmentation and threat detection.
- Edge compute: Optional Cisco IOx support for running containerized applications locally.

Primary use cases:
- Smart factories: Powering robotic arms, AGVs (automated guided vehicles), and condition-monitoring sensors.
- Oil and gas: Remote pipeline monitoring with LTE backup in unstaffed locations.
- Public transit: Onboard passenger Wi-Fi and surveillance systems with real-time data offload.
C1111X-8P vs. Lower-Port IR1100 Models
| Feature | C1111X-8P | C1111-4P |
|---|---|---|
| PoE Ports | 8x PoE+ (240W total) | 4x PoE+ (120W total) |
| LTE Redundancy | Dual modems (active/active) | Single modem |
| Edge Compute | Cisco IOx supported | Not available |

Choose the 8P model if:
- Your deployment requires high-density PoE for multiple high-wattage devices.
- Dual LTE failover is critical for mission-critical operations.
- Local data processing via edge computing reduces cloud dependency.
Addressing Critical Deployment Questions
Q: How does dual LTE improve uptime compared to single-modem routers?
The active/active modem configuration allows simultaneous use of two carriers, boosting bandwidth and reducing failover time to <10 seconds during outages.
—
Q: Can it power 8x 30W devices simultaneously?
Yes, but ensure the total draw stays under 240W. For example, 8x 25W APs would consume 200W, leaving 40W for auxiliary devices.
—
Q: Is SD-WAN licensing included?
No—C1111X-8P requires a separate Cisco SD-WAN subscription for advanced routing and security features.
Sourcing and Lifecycle Support
For guaranteed hardware authenticity and warranty coverage, purchase the C1111X-8P through authorized partners like itmall.sale. Ensure firmware is updated to IOS-XE 17.9 or later for LTE stability and security patches.
Final Perspective
The C1111X-8P redefines rugged networking by merging high-power PoE with carrier-grade LTE redundancy—a combination rarely found in industrial routers. While its upfront cost may deter budget-limited projects, the ROI becomes evident in environments where a single outage could halt production or compromise safety. For industries navigating digital transformation amid harsh conditions, this router isn’t just a connectivity tool; it’s a strategic asset.
