ComNet CNGE2+2SMS: Mini Intelligent 1Gb Ethernet Ring Switch, 4 Ports: 2 x Gigabit Electrical Ports, 2 x Gigabit SFP Ports, Optional PoE, Optional Contact Closure, Self-managed

The ComNet CNGE2+2SMS[POE][HO] is a 4-port mini, intelligent switch with light management functionality. It provides two 10/100/1000Base-T(X) copper ports and two 100/1000Base-FX SFP* ports. The CNGE2+2SMS[POE][HO] provides exclusive functionality for easy field deployment including DIP switch based operation of RSTP for creating redundant network topologies as well as preventing network video flooding of multicast traffic when used in a linear or star topology. Ports 1 and 2 can optionally supply up to 30W of power per port based on the IEEE 802.3at standard. An optional High Output (HO) version is also available that can supply up to 60W of PoE from ports 1 and 2.

This product is fully compatible with the ComNet exclusive CopperLine® SFP modules for operation over extended distance UTP or coax cable.
