8 Linking Main Stations
This chapter describes how to link Main Stations. You can connect Main Stations directly
using Ethernet or Fiber, or connect them over a LAN via Ethernet.
Main Station linking is achieved using interface modules fitted to the extension bay of the Main
Station. There are two modules:
• Ethernet interface module (HLI-ET2). This module provides an Ethernet connection
between Main Stations.
• Fiber interface module (HLI-FBS). This module provides a Fiber connection between
Main Stations.
Each Main Station has four channels, and can connect up to 20 beltpacks.
Note: If you change the network topology between any two stations, you must reboot the stations.
Warning: Both ports are configured to bridge traffic from one port to the other
in order to work in daisy-chain. Spanning Tree Protocol is not enabled on those
ports, therefore do not connect them both to the same network.
8.1 Linking scenarios
Main Stations are connected together using CAT, CAT5e or CAT6 shielded cable. They can
also be connected using fiber. There are various topologies that you can create. Some of
these are illustrated below.
