ERSG9 Series

9 Port Rack-mount Switch
All COPPER or All FIBER or ANY Combination

Switches | ERSG9

Documentation

  • ERSG9 Series Data Sheet PDF

This layer 2 switch has been designed for great flexibility at a very reasonable price. Copper 10/100TX & Fiber FX can be mixed on ports 1 through 8. Port 9 can be 10/100/1000 copper or Gigabit SX or LX fiber. The FX ports can be SC single mode (up to 50 km) or multi-mode (2 km) ST or SC. Triple speed products like this allow you to leverage existing technology without investment in software and personal training.

Management via console port for VLANs, QOS, Port Trunking and a number of functions.

GigE & Fast Ethernet LAN switch was designed in order to ensure cost effective, simple migration from 10 Mbps to 100 Mbps to 1000 mbps maintaining the Ethernet transmission protocol, Carrier Sense Multiple Access Collision Detection (CSMA/CD). Triple speed products offer the ability to leverage your existing network investment.
