The ComNetTM CNGE4US Ethernet 4 port unmanaged switches are designed to transmit and receive 10/100/1000 Mbps data using small form factor pluggable modules. Both are environmentally hardened to operate in demanding environments. LED indicators are provided for confirming equipment operating status. Plug-and-play design ensures ease of installation requiring no optical adjustments. These units are interchangeable between stand-alone or card mount configurations.
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 the Caltrans Specification for Traffic Signal Control Equipment.
Voltage transient protection on all power and signal input/output lines provides unconditional protection from power surges and other voltage transient events.
