Comnet CNGE28FX4TX24MSPOE+ (24) 10/100/1000 BASE-TX + (4) 1000BASE-FX Managed Switch with Power over Ethernet (PoE).

The ComNet CNGE28FX4TX24MSPOE+ Layer 2 Managed 28-Port Ethernet Switch supports twenty-four (24) 10/100/1000 Base-TX ports and four (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 (4) 1000BASE-FX combination ports are 1000 TX or Comnet SFP Configurable for fiber type (multi-mode or single-mode), connector type and distance. The exclusive C-Ring redundant ring feature protects networks from interruptions or temporary malfunctions with its fast recovery technology. Legacy ring allows the switch to be used in an existing ring of ComNet X-Ring enabled switches. eConsole, a powerful, easy-to-use Windows-based utility, allows the CNGE28FX4TX24MSPOE+ to be centrally managed. The electrical ports support the 10/100/1000Mbps Ethernet IEEE 802.3 protocol, and auto-negotiating and auto-MDI/MDIX features are included. The CNGE28FX4TX24MSPOE+ are optically (1000BASE-FX) and electrically compatible with any IEEE 802.3 compliant Ethernet device and are hardened for use in harsh 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.

Tested and certified by an independent laboratory for full compliance with the environmental requirements (ambient operating temperature, mechanical shock, vibration, humidity with condensation, high-line/low-line voltage conditions and transient voltage protection) of NEMA TS-1/TS-2 and CALTRANS Traffic Signal Control Equipment Specifications.
