Overview of Cisco C1109-2PLTEGB
The Cisco C1109-2PLTEGB is a ruggedized Industrial Ethernet 1100 Series switch designed for mission-critical deployments in harsh conditions. Combining 2x Gigabit PoE+ ports, LTE cellular backup, and an operating temperature range of -40°C to 75°C, this device ensures uninterrupted connectivity for industrial IoT (IIoT), transportation, and utility networks. The “2PLTEGB” designation highlights its dual PoE+/LTE capabilities and Gigabit uplinks, making it a versatile solution for environments where reliability is non-negotiable.
Key Technical Specifications and Industrial Use Cases
Hardware and resilience features:
- PoE+ support: 30W per port (60W total) for devices like IP cameras, wireless APs, or sensors.
- LTE redundancy: Integrated CAT-M1 modem for failover during primary WAN outages.
- Rugged design: IP30-rated metal enclosure, vibration resistance, and corrosion-proof components.
- Layer 2 features: VLANs, QoS, and port security for traffic prioritization in OT/IT converged networks.

Typical deployments:
- Oil and gas facilities: Monitoring remote pipelines with LTE backup in areas lacking fiber.
- Railways: Powering onboard surveillance systems and passenger Wi-Fi.
- Smart grids: Connecting substation equipment in extreme temperatures.
C1109-2PLTEGB vs. Non-LTE Industrial Switches
| Feature | C1109-2PLTEGB | C1100-8P-E-L (Non-LTE) |
|---|---|---|
| WAN Redundancy | LTE failover | None |
| PoE Budget | 60W total | 130W total |
| Operating Temp | -40°C to 75°C | -25°C to 60°C |

Choose this model if:
- Your operations demand cellular backup for critical communications.
- Deployments occur in extreme cold or heat (e.g., Arctic sites or desert solar farms).
- Space constraints favor compact, all-in-one solutions over separate LTE routers.
Addressing Core Deployment Concerns
Q: How does LTE failover work during network outages?
The switch automatically switches to LTE when primary WAN (fiber/copper) fails, with sub-30-second failover times. Data usage depends on carrier plans.
—
Q: Can it power high-demand devices like PTZ cameras?
Yes, but ensure total PoE draw stays under 60W. A PTZ camera requiring 25W leaves 35W for additional devices.
—
Q: Is it compliant with industrial safety standards?
Yes, it meets IEC 61850-3 (power utilities) and IEEE 1613 (transportation) for electromagnetic and shock resistance.
Sourcing and Support Considerations
For guaranteed authenticity and lifecycle support, purchase the C1109-2PLTEGB through authorized partners like itmall.sale. Ensure firmware is updated to IOS 15.2(7)E or later for LTE stability and security patches.
Final Perspective
The C1109-2PLTEGB exemplifies Cisco’s focus on bridging IT and OT networks in environments where failure isn’t an option. While LTE adds upfront costs, its value in preventing costly downtime—whether in a frozen pipeline or a moving train—cannot be overstated. For industries lagging in digital transformation due to connectivity risks, this switch is a pragmatic step toward resilient automation.
