Half-Duplex/Full-Duplex Jumpers

Each twisted pair and fiber optic port on a

TotalSwitch Module

can

operate in either Half-Duplex (HDX) or Full-Duplex (FDX) mode.

TotalSwitch Modules

are shipped from the factory with HDX selected

on each port. HDX/FDX is selected on 

TotalSwitch Modules

by

repositioning the shunts on the 3-pin, HDX/FDX jumper blocks on

the PCB.

The HDX/FDX jumper blocks on 

TotalSwitch TP/8 Modules

are

located at position JA1 and labeled 1 - 8. The HDX/FDX jumper

blocks on 

TotalSwitch TP/4+FO/2 Modules

are located at positions

JP5-10 (and labeled with the corresponding port). The HDX/FDX

jumper blocks on 

TotalSwitch FO/4 Modules 

are located at positions

JP4 for Port 1 (labeled Port 0 on the PCB), JP5 for Port 2 (labeled 

Port 1 on the PCB), JP6 for Port 3 (labeled Port 2 on the PCB) and JP7

for Port 4 (labeled Port 3 on the PCB).

Select FDX by positioning the shunt over the top and center pins.

Select HDX (factory default) by positioning the shunt over the center

and bottom pins.  

Factory Test Jumpers

The jumper blocks located at position JP1 on 

TotalSwitch

TP/4+FO/2 Modules

and at position JP8 on 

TotalSwitch FO/4 Modules

are for factory test purposes only. These jumpers are configured at the

factory and should not be changed. The default setting is with the

shunt positioned on the top two pins.

Installing TotalSwitch Modules in Modular Concentrator

Hubs

TotalSwitch Module

s can be installed into any available slot in any

collision domain on any 

Modular Concentrator

hub (e.g.: 

Modular

Concentrator/12, Modular Concentrator/5

and 

Modular

Concentrator/2

). For specific installation and operation information

on 

Modular Concentrator

hubs, please refer to the manual included

with the hub.

NOTE: TotalSwitch Modules are not capable of being managed

even when installed in a Modular Concentrator hub using SNMP

managment.
