Network Connection and Termination
Your MicroVAX 3100 Model 88/98 System can be connected to either a ThinWire
Ethernet or a ThickWire Ethernet network. A jumper on the system board determines
whether you are using ThinWire or ThickWire Ethernet.
If you do not use an Ethernet network, you should install the ThinWire and ThickWire
terminators on the back of your system as shown in Figure 2-12 and Figure 2-19
respectively.
If you will be using either ThinWire or ThickWire Ethernet, follow these general steps,
which are detailed in the following sections.
1. Select ThinWire or ThickWire by installing the jumper on the system board.
2. Assemble/connect the network to the appropriate port.
3. Test the network connection.
4. Notify the network coordinator to complete the installation.
Selecting ThinWire or ThickWire Ethernet
Select either ThinWire Ethernet or ThickWire Ethernet by installing the selector jumper
on the system board module. Install the jumper in the setting position for ThinWire
Ethernet, and in the setting position for ThickWire Ethernet (See Figure 2-8).
