5.
The external power supply is mounted on the Express 8-Port Mux’s rear panel. The AC power cord must
be firmly inserted into the external power supply and strain relieved.
6.
Plug the other end of the AC power cord into a properly wired outlet. All data and mode LEDs on the
Express 8-Port Mux will activate for two seconds and fade off. The amber power LED on the front panel,
the green power LED on the top of the external power supply, and the TX LED will activate and remain
on. At this time the data activity LEDs will flash at the host’s polling rate. The RX LED will be off until the
remote Mux is installed.
4.2 Device-Side Multiplexor Installation
1.
Set the configuration switches on the rear panel of the device-side Express 8-Port Mux as follows:
Switch 1 OFF and Switch 2 ON for a point-to-point application
or
Switches 1 and 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 finish.
WARNING
Do not look into any fiber optic connector or fiber optic cable.
3.
The Express 8-Port Mux has ST fiber optic connectors. For point-to-point applications, connect the
multimode fiber optic cable attached to the host side Multiplexor’s “TX” to the device side Multiplexor’s
“RX” optical link connector located on the rear panel of the Express 8-Port Mux, and connect the
multimode fiber optic cable attached to the host side Multiplexor’s “RX” to the device side Multiplexor’s
“TX” optical link connector located on the rear panel of the Express 8-Port Mux. For ring applications,
connect the fiber optic TX of a Multiplexor to the fiber optic RX of the next multiplexor downstream in
the ring until the ring is complete. Make sure that the cables are properly strain relieved and labeled.
4.
Connect the Express 8-Port Mux ports to the host ports of the active- or passive-star hub and follow the
installation procedure for the hub.
5.
The external power supply is mounted on the rear panel of the Express 8-Port Mux. The AC power cord
must be firmly inserted into the external power supply and strain relieved.
6.
Plug the other end of the AC power cord into a properly wired outlet. All data and mode LEDs on the
Express 8-Port Mux will activate for two seconds and fade off. The amber power LED on the front panel,
the green power LED on the top of the external power supply, and the “TX and RX” LEDs will activate
and remain on. If any terminals are on, the data activity LEDs will activate. If express devices and an
express host are attached, the port status LEDs (upper green LEDs) will activate. Devices in a ring
application will not show a sign-on screen until the ring is complete.
