Using the Ethernet Port

 

 

 

 

 

Cabling Schemes

 

 

 

Introduction

 

 

 

 

In a standard Ethernet cabling scheme, each device connects via a cable to a port

 

on a central Ethernet hub.

 

 

Length

 

 

 

 

The maximum length of cable between devices depends on the type of hub used,

 

as shown in the following table:

Note: 10/100 hubs/switches can be used. This will allow 100 Base T networks to use the M1E.
