Edge Switch with 100 Mb Fiber

RFL 3000 ES42H Edge Switches go out where the action is. In heavy-duty electrical substation applications, Ethernet LANs increasingly are used where small groups of nodes at the edge need to be connected into larger LAN structures. The RFL 3000 ES42H , a versatile family of small Edge Switches, uses the latest networking technology and innovative product packaging features to serve edge-of-the-network applications.

The compact RFL 3000 ES42H Edge Switch design delivers 6 Ethernet ports. The base models have either two 100 Mb fiber and 4 10/100 copper ports, or one fiber and five copper ports, or 6 copper ports. Fiber port choices cover all multi-mode and single-mode fiber connector types. Power input selections include AC or DC (or both) with 12V, 24V and 48V DC terminal block models.

The RFL 3000 Switches include Link-Loss-Learn (LLL), enabling them to be used in self-healing and redundant LAN structures. The LLL feature causes RFL 3000 ES42H Switches to sense Link Loss or standard STP / RSTP reconfiguration signals on designated ports, flush internal address buffers to permit a change in LAN packets flow, and pass the reconfiguration signal down the line to other products in the redundant network structure. RFL3000 Switches, combined with managed switches running STP or RSTP or S-Ring, can often provide high availability redundant LANs at lower total cost than was previously possible.

The RFL 3000 ES42H Hardened units are designed for substations. The RFL 3000 ES42H models are built with high-grade components and are constructed using special thermal techniques (patent pending) and a metal case for heavy-duty industrial jobs. In addition to a Hardened AC power option and jack, terminals for internal DC power choices at 8 to 15V, 24V or -48V DC are included. Two terminals provide connections to monitor an internal power-sense relay. The ambient temperature rating is for industrial use. No internal air flow is required for cooling, so it resists dust, dirt, moisture, smoke and insects. Mounting choices include stand-alone panel-mounting, DIN-Rail, or rack-mount tray.

All RFL 3000 ES42H Edge Switch models come with two (2) sets of LED indicators. One set is on the front for viewing convenience when the unit is DIN-Rail or wall-mounted, and one LED set is mounted in the end adjacent to the ports for easy viewing when units are in a rack-mount tray. The RFL3000 ES42 Edge Switches are designed and manufactured in the USA and backed by a three-year warranty.
