The ComNet
™
CNGE28FX4TX Managed Redundant Ring Ethernet Switch
provides robust transmission of (24) 10/100/1000BASE-T(X) ports and (4) 1000BASE-
FX ports of Ethernet data. Fully compliant with IEEE 802.3at, up to 720 watts of PoE or
PoE+ power is available for distribution across all 24 Base-TX ports. The four 1000BASE-
FX ports may be used with multimode or single-mode optical fiber when used with
ComNet SFPs. The exclusive C-Ring protects mission-critical applications from network
interruptions or temporary malfunctions with its fast recovery technology. eConsole,
a powerful, easy-to-use Windows-based utility, allows the CNGE28FX4TX
to be centrally managed. Diverse media selection provides for easy implementation
of point-to-point, linear add-drop, drop-and-repeat, star, or true self-healing ring and
mesh network system architectures. The electrical ports support the 10/100/1000Mbps
Ethernet IEEE802.3 protocol, and auto-negotiating and auto-MDI/MDIX features
are included for simplicity and ease of installation. These network-managed layer 2
switches are optically (1000BASE-FX) and electrically compatible with any IEEE802.3
compliant Ethernet device. Unlike most Ethernet switches, the environmentally
hardened CNGE28FX4TX is designed for direct deployment in difficult
out-of-plant or roadside operating environments. Featuring a low-profile 1-RU high
rack-mountable package, these units may be mounted within any standard 19-inch
rack cabinet, and the high-capacity power supply for operation of the switch and PoE
PSE (Power Sourcing Equipment) is completely self-contained.
