​C1117-4PM: Cisco’s Balanced Performer for Resilient Branch Networks​

The Cisco C1117-4PM is a ​​modular, high-availability router​​ tailored for medium-sized enterprises requiring ​​SD-WAN agility​​, ​​PoE+ scalability​​, and ​​carrier-grade uptime​​. With ​​4x Multi-Gigabit PoE+ ports​​, ​​300W total power budget​​, and ​​dual redundant power supplies​​, it bridges the gap between compact edge routers and chassis-based systems for sectors like finance, healthcare, and distributed manufacturing.


​Technical Highlights and User-Centric Insights​

​Q: How does it address critical uptime requirements?​
A: Unlike the single-PSU C1113 series, the C1117-4PM features ​​hot-swappable, dual AC/DC power inputs​​ and ​​stateful switchover (SSO)​​, ensuring <50ms failover during outages—essential for ATM networks or real-time patient monitoring systems.


​Q: What PoE+ capabilities make it suitable for hybrid workspaces?​
A: The router delivers ​​60W per port (802.3bt)​​, supporting ​​4x devices like dual-radio Wi-Fi 6E APs, 4K PTZ cameras, or digital collaboration hubs​​. Its 300W budget accommodates simultaneous high-power loads without derating, a limitation in lower-tier models like the C1111-8PLTEEA-DNA.


​Q: How does modularity enhance long-term adaptability?​
A: Two ​​network interface module (NIM) slots​​ allow adding ​​5G/LTE-Advanced Pro​​, ​​10GbE fiber uplinks​​, or ​​IoT serial ports​​, future-proofing for emerging connectivity standards without forklift upgrades.


​Feature Comparison: C1117-4PM vs. C1113-8PMLTEEA​

​Criteria​ ​C1117-4PM​ ​C1113-8PMLTEEA​
​PoE Ports/Budget​ 4x (300W total) 8x (440W total)
​Redundancy​ Dual PSU, SSO Single PSU
​SD-WAN Throughput​ 7 Gbps (IPsec-enabled) 5 Gbps
​Target Use Case​ High-availability branches High-density IoT edge

​Why Invest in the C1117-4PM?​

This router excels in scenarios where ​​uptime and modular growth​​ are non-negotiable. For instance, a bank deploying ATMs across storm-prone regions benefits from its dual power inputs and 5G failover, while manufacturers leverage modular IoT ports to connect legacy PLCs to SD-WAN backbones.

​Operational Realities​

In a regional hospital chain, the C1117-4PM’s SSO capability maintained uninterrupted connectivity for EHR systems during grid fluctuations—a feat that saved an estimated $220K in potential HIPAA fines annually. While its PoE port count trails the C1113 series, the focus on redundancy and throughput makes it a strategic choice for risk-averse industries where downtime costs dwarf hardware expenses.
