Introduction

TotalSwitch 6 10-Mbps Modules™ are IEEE 802.3 multi-port

switchs that provide eight 10Base-T (Half- or Full-Duplex), four

10Base-2 (Half-Duplex), four 10Base-FL (Half- or Full-Duplex) or four

10Base-T (Half- or Full-Duplex) and two 10Base-FL (Half- or Full-

Duplex) switched segments.

TotalSwitch 6 10-Mbps Modules use non-blocking switching

architecture, provide wire speed switching (14,880 pps) for each

segment and ensure extremely low latency.

Each TotalSwitch 6 10-Mbps Module features Store-and-Forward

switching, a self-learning mechanism with advanced address

recognition that holds eight thousand addresses and includes a 1MB

packet buffer for high performance.

Chapter 2

Hardware Installation

This chapter provides configuration and installation information for

TotalSwitch 6 10-Mbps Modules (referred to as Total Switch Modules

throughout the rest of this manual).

Jumper Settings

TotalSwitch TP/8, TotalSwitch FO/4 and TotalSwitch TP/4+FO/2

have several jumpers that may need to be configured. It is necessary

to power down the unit before adjusting the jumper settings.

NOTE: To change the settings once a TotalSwitch Module is

installed, it is necessary to remove the PCB from the chassis. To do

this, loosen the thumbscrews on the face of the chassis, then slide

the PCB out of the chassis. After configuration is complete, slide

the PCB back into the chassis and tighten the thumbscrews.

The following diagrams show the jumper locations and default

settings on the various TotalSwitch Modules.

NOTE: Ports are labeled on the PCB as well as on the front of the

module. The HDX/FDX jumpers at JA1 on TotalSwitch TP/8 are

numbered in reverse order (i.e jumper 1 corresponds to Port 8,

jumper 2 corresponds to Port 7, etc. Refer to the diagram of

TotalSwitch TP/8)

2.1

Figure 2.1 Jumper Locations and Default Settings for

TotalSwitch TP/8

Figure 2.2 Jumper Locations and Default Settings for

TotalSwitch FO/4

2.2

Figure 2.3 Jumper Locations and Default Settings for

TotalSwitch TP/4+FO/2

FiberAlert Jumpers

TotalSwitch FO/4 Modules (board revisions -20 and higher) and

TotalSwitch TP/4+FO/2 Modules feature FiberAlert. When a fiber

optic receive fault is detected, FiberAlert makes the link LED for the

opposite end of the fiber conversion pulse, signifying there is a

problem and thus eliminating “silent failures.”

FiberAlert is enabled/disabled on each fiber port of a TotalSwitch

Module by repositioning the shunts on the 3-pin, FiberAlert jumper

blocks on the PCB. TotalSwitch Modules are shipped from the factory

with FiberAlert disabled on each port.

The FiberAlert jumper blocks on TotalSwitch TP/4+FO/2 Modules

are located at positions JP15 (Port 1) and JP16 (Port 2). The FiberAlert

jumper blocks on TotalSwitch FO/4 Mdoules are located at positions

JP12 for Port 1 (labeled Port 0 on the PCB), JP11 for Port 2 (labeled

Port 1 on the PCB), JP10 for Port 3 (labeled Port 2 on the PCB) and

JP9 for Port 4 (labeled Port 3 on the PCB).

Enable FiberAlert by positioning the shunt over the top and center

pins. Disable FiberAlert (factory default) by positioning the shunt over

the center and bottom pins.

2.3

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 Modules 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.

2.4

To install a TotalSwitch Module, remove the blank bracket covering

the slot where the module is to be installed by removing the two

screws located closest to the outside edge of the bracket.

NOTE: TotalSwitch Modules cannot be installed in Slot 1; this

disables SNMP for the Modular Concentrator’s NMS.

Next, slide the module into the chassis until it is seated securely in

the connector on the backplane. Secure the module to the chassis by

tightening the thumbscrews.

Figure 2.4 Installing a TotalSwitch Module in a Modular Concentrator

Hub

To complete the installation of a Modular Concentrator hub, refer

to the manual included with the hub for more information.

Installing TotalSwitch Modules in TotalSwitch 6

TotalSwitch Modules can be installed into any available slot in any

modular TotalSwitch 6. Before installing a TotalSwitch Module in a

TotalSwitch 6 chassis, the resistor packs on the module must be

removed from the sockets on the rear of the PCB (lift the resistor pack

from the socket). Refer to the diagrams of the modules earlier in the

chapter for socket location.

NOTE: The sockets are located in the same general location on

TotalSwitch BNC/4.

To install a TotalSwitch Module, remove the blank bracket covering

the slot where the module is to be installed by removing the two

screws located closest to the outside edge of the bracket.

Next, slide the module into the chassis until it is seated securely in

the connector on the backplane. Secure the module to the chassis by

tightening the thumbscrews.
