What the Specifications Mean for Real Deployments
The specification table reveals several important design principles:
- EI models offer greater switching and forwarding headroom, ideal for large campuses and enterprise access layers with long lifecycle expectations.
- High-density fiber models (54S, 52S) save rack space and simplify cabling in large buildings.
- PoE models are crucial for modern networks where endpoints require both data and power.
- Standard 10GE uplinks across the series prevent upstream bottlenecks as access-layer demand grows.
These characteristics ensure the S5500S series aligns closely with access-layer requirements leading up to 2026 and beyond.
Powering the Network Edge with PoE
