7. Disconnect all cables prior to configuration.
8. Devices attached to the UTP network must comply with the voltage and current
limits for Class 2 Power-Limited Signal Circuits as defined by article 725 of the
National Electrical Code and Section 16 of the Canadian Electrical Code.

4.1 Host-Side Multiplexor Installation
1.
Set the configuration switches on the rear panel of the host-side Express 8-Port Mux as follows:
Switches 1 and 2 ON for a point-to-point application
Switch 1 ON and Switch 2 OFF for a ring application.
2.
The Express 8-Port Mux is designed for a 19" rack. The unit should be properly installed using all four
mounting holes. Rack hardware is not provided. We recommend using plastic or nylon washers under
mounting screws to protect the chassis's finish.
3.
A polling group is a group of ports which have one port active at a time. The new AS/400 workstation
controllers (WSCs) have two polling groups. Ports 0 through 3 and ports 4 through 7 constitute the two
groups. The Express 8-Port Mux can accommodate two polling in the same fashion. Do not connect more
than one host polling group to an Express 8-Port Mux polling group. Connect the host ports to the Express 8-Port
Mux ports.
Do not look into any fiber optic connector or fiber optic cable.
4.
The Express 8-Port Mux has ST fiber optic connectors. Connect the multimode fiber optic cables to the
optical link connectors on the rear panel of the Express 8-Port Mux. Note the fiber color or number on
the "TX" and "RX" to ensure proper connection to the remote multiplexor. Strain relieve and label all
cables.
