Port

Description

 

 

 

 

Power port

A mini-DIN8 power adapter cable connection.

Line or Telco port

A telephone-style jack labelled “Telco1” or “Line” for your WAN connection. Use

 

the “Telco 1" or “Line 1" port, NOT “Telco 2" or “Line 2."

 

 

Console port

A DE-9 console port for a direct serial connection to the console screens. You

 

can use this if you are an experienced user and don’t want to use the preset

 

192.168.1.1 IP address in the router. See “Connecting a local terminal console

 

cable to your router” on page 6-3.

 

 

Auxiliary port

An HD-15 auxiliary port for attaching an external modem or the optional

 

AppleTalk kit.

 

 

Crossover switch

A crossover switch with Normal and Uplink positions. If you use Ethernet Port

 

#1 for a direct Ethernet connection between a computer and the router, set the

 

switch to the Normal position. If you are connecting the router to an Ethernet

 

hub, use Ethernet port #1 on the router and set the switch to the Uplink

 

position.

 

 

8-port Ethernet hub

Eight Ethernet jacks. You will use one of these to configure the Netopia R3100.

 

For a new installation, use the Ethernet connection. You can either connect your

 

computer directly to any of the Ethernet ports on the router, or connect both

 

your computer and the router to an existing Ethernet hub on your LAN.

 

Alternatively, you can use the console connection to run console-based

 

management using a direct serial connection.

 

 

S/T Termination

Netopia R3100 S/T models also provide an S/T termination switch. The S/T

switch

termination switch on the Netopia R3100 back panel must be enabled to

 

terminate the S/T bus. To enable this parameter, the switch must be toggled to

 

the left.
