Overview of Cisco C1127-8PLTEP
The Cisco C1127-8PLTEP is a high-capacity industrial router built for environments demanding robust Power over Ethernet (PoE) and cellular redundancy. Part of Cisco’s IR1100 series, it features 8x PoE+ ports, dual LTE-Advanced Pro modems, and Cisco IoT Operations Dashboard integration, tailored for energy-intensive IoT deployments in harsh conditions. Its ruggedized design and advanced power management cater to industries like manufacturing, utilities, and transportation.
Key Technical Specifications and Industrial Applications
Hardware and performance highlights:
- PoE+ capacity: 30W per port (240W total), supporting devices such as IP cameras, wireless APs, and industrial sensors.
- LTE redundancy: Dual CAT-12 modems with carrier aggregation ensure <5-second failover and speeds up to 600 Mbps.
- Rugged design: Operates in -40°C to 75°C, with IP67-rated enclosure and MIL-STD-810G compliance for shock/vibration resistance.
- Edge compute: Runs Cisco IOx applications for localized data processing, reducing latency for real-time analytics.

Choose the C1127-8PLTEP if:
- Your deployment prioritizes PoE port density over ultra-high wattage.
- Cost-effective LTE redundancy is sufficient for operational needs.
- Localized data processing requires moderate edge compute resources.
Addressing Critical Deployment Concerns
Q: Can all 8 PoE+ ports deliver 30W simultaneously?
Yes, but thermal derating applies in extreme temperatures. At 75°C, limit to 25W/port to avoid overheating.
—
Q: How does it integrate with legacy SCADA systems?
Supports Modbus TCP and DNP3 protocols, enabling seamless communication with PLCs and RTUs.
—
Q: Is 5G support available?
No—this model uses LTE-Advanced Pro. For 5G, consider the C1121X-8PLTEP++.
Sourcing and Lifecycle Support
For guaranteed authenticity and technical support, purchase the C1127-8PLTEP through authorized partners like itmall.sale. Ensure firmware is updated to IOS-XE 17.9.3 for LTE stability and security patches.
Final Insight
The C1127-8PLTEP strikes a balance between PoE density and industrial-grade reliability, making it a workhorse for sectors where moderate power and connectivity meet mission-critical uptime. While it lacks the flashier 5G or PoE++ specs of premium models, its cost efficiency and rugged simplicity make it indispensable for organizations scaling IoT without overengineering. In industries like logistics or utilities, where every port and watt counts, this router isn’t just a device—it’s the backbone of resilient automation.
