Chapter 1
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.
