Overview
Introduction
CNGE28FX4TX24MSPOE+ series is managed Redundant Ring Ethernet switch with 24
10/100/1000BASE-T(X) ports with PoE (PSE) function and 4x1000BASE-X SFP ports. With
completely support of Ethernet Redundancy protocol, C-Ring (recovery time < 30ms over 250
units of connection), Legacy Ring and MSTP/RSTP/STP (IEEE 802.1 s/w/D) can protect your
mission-critical applications from network interruptions or temporary malfunctions with its fast
recovery technology. ComNet switches provide advanced IP-based bandwidth management
that can limit the maximum bandwidth for each IP device. Users can configure IP cameras and
Network Video Recorders with more bandwidth and limit other device bandwidth. ComNet
switches also support application-based QoS (Quality-of-Service). Application-based QoS
can set highest priority for data stream according to the TCP/UDP port number. The ComNet
special IP police function can only permit allowed IP address with MAC address to access the
networking. Hacker cannot access the IP surveillance network without permission. It can avoid
hackers from stealing video privacy data and attacking IP camera, Network Video Recorders and
controllers. ComNet switches also provided advanced DOS/DDOS auto prevention. If there is
any IP flow become big in short time, ComNet switches will lock the source IP address for certain
amount of time to prevent the attack. Its hardware based prevention so it can prevent DOS/
DDOS attack immediately and completely. CNGE28FX4TX24MSPOE+ series also supports Power
over Ethernet, a system to transmit electrical power up to 30 watts, along with data, to remote
devices over standard CAT5/5-e/6 cable in an Ethernet network. Each CNGE28FX4TX24MSPOE+
series switch has 24 10/100/1000BASE-T(X) PSE (Power Sourcing Equipment) ports. PSE is a
device (switch or hub for instance) that will provide power in a PoE connection. All functions of
the CNGE28FX4TX24MSPOE+ series can be centrally managed by a powerful windows utility,
eConsole. These switches are one of the most reliable choices for highly managed and Gigabit
Fiber Optic Ethernet applications requiring PoE.
