CNGE2+2SMS[POE][HO]
10/100/1000 MBPS INTELLIGENT REDUNDANT RING
GIGABIT SWITCH WITH OPTIONAL POE+
The ComNet CNGE2+2SMS[POE][HO] is a four port 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 with IGMP snooping. Ports 1 and 2 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 and 2. 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.
