Features

Overview

EtherCom's ERM series of rack-mount media converters are designed to allow the network designer to add fiber segments as needed.

Description

The ERM12 100BaseTX to 100BaseFX media converter, allows 100BaseTX specifications to be used over fiber cable. The ERM02 offers similar features at 10 Mbps.
Designed to meet the needs of today's network planners to intergrate Ethernet performance with the benefits of fiber segments, The media converters comply with the 100BaseTX 802.3u and 10BaseT 802.3 standards.
A complement of six LEDs display power for the unit, polarity, plus link and receive on each segment. Each RJ45 port features a MDI/MDIX, uplink, downlink, crossover switch that dispenses with the any need for specially configured cables.
Unlike other manufactures who require that you purchase two different media converters to run either half or full duplex. EtherCom's converters look to see if they are connected to half or full duplex devices and automatically configure themselves.
The built in auto sensing power supply can be augmented with a second redundant power supply for added protection.
The chassis allows you to mix up to twenty-one 10 or 100 Mbps hot swappable modules.
