The ComNet CNGE4+2SMS[POE][HO]/M is a six port intelligent switch with light management
functionality. It provides four 10/100/1000Base-T(X) copper ports and two 100/1000Base-FX SFP*
ports. The CNGE4+2SMS[POE][HO]/M 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 using IGMP snooping. Ports 1 through 4
can optionally supply up to thirty (30) watts 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 sixty (60) watts of PoE
from ports 1 through 4. This product is fully compatible with the ComNet exclusive CopperLine®
SFP modules for operation over extended distance UTP or Coax cable. The ComNet exclusive Port
Guardian feature provides additional cyber security protection by enabling physical port lockout in
the event that an existing cable is disconnected and prevents a potential network incursion using
common spoofing techniques. The intrusion event is reported back to the operator using SNMP.
