The FUMS-G Series Ethernet 4- and 8-port unmanaged switches are designed to transmit and receive 10/100/1000BASE-T(X) or 1000FX data through user-selectable small form-factor pluggable (FSFP) transceivers (ordered separately). The plug-and-play design of these FSFP modules ensures ease of installation requiring no electrical or optical adjustments. Modular in design, these models may be either wall- or rack-mounted. LED indicators display operating status and critical operating parameters. These models are designed to operate in extreme environments. External power is required for the FUMS-G Series units. The units can be powered with the recommended FEXTPS fiber external power supply. The optical transmission of Ethernet-compatible IP camera surveillance video makes the FUMS-G Series ideal for transportation, airport, and college campus applications.
