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.
2.5

To complete the installation of a TotalSwitch 6, refer to the
TotalSwitch 6 Installation Guide included with the chassis.
BNC Port Termination
When using the BNC port, the port termination may need setting.
TotalSwitch BNC/4 features
a 2-position switch next to
each BNC connector that
allows a thin coaxial
segment to be terminated
at the hub/chassis without
an additional ‘T’ connector
and terminator. Figure 2.5 BNC Termination Switch
If the TotalSwitch Module is attached
to the mid-point of a thin Ethernet
segment, attach a ‘T’ connector to the
BNC port. Termination must be OFF
(disabled – factory default). Termination
is disabled when the toggle is in the
down position.
Figure 2.6 BNC Termination
If a thin Ethernet segment is to be terminated at the TotalSwitch
Module, attach the cable directly to the BNC connector and set the
termination switch to ON (enabled) by moving the toggle to the up
position.
NOTE: When the BNC port is not being used, Black Box
recommends the toggle be set to ON and a 50
Ω terminator be
connected to the port.
LEDs
TotalSwitch Modules feature diagnostic LEDs per port. The
following diagrams show the LEDs on TotalSwitch TP/8, BNC/4 and
FO/4 Modules. Refer to the sections “LEDs on Twisted Pair Ports” and
“LEDs on Fiber Ports” for LED information on TotalSwitch TP/4+FO/2
Modules.

Chapter 3
User Guidelines
As stated earlier, TotalSwitch Modules are 10 Mbps Ethernet, multi-
port switchs that provide eight 10Base-T (Half- or Full-Duplex in any
combination), four 10Base-2 (Half-Duplex) or four 10Base-FL (Half-
or Full-Duplex in any combination) or four 10Base-T (Half- or Full-
Duplex) and two 10Base-FL (Half- or Full-Duplex) switched
segments. This chapter discusses how to use a TotalSwitch Module in
a network.
TotalSwitch Installation Examples
PROBLEM 1: Your network performance is suffering because you
have too many nodes creating too much traffic.
SOLUTION: By installing a TotalSwitch Module, as illustrated in
Figure 3.1, you will decrease traffic congestion and, at
the same time, increase your network’s performance.
Figure 3.1
PROBLEM 2: You need to connect two 10 Mbps Ethernet
networks located in different buildings. The buildings
are farther apart than the IEEE 802.3 specification allows
(e.g.: maximum distance is 2 km on a fiber optic link
segment).
SOLUTION: In order to make a connection beyond the IEEE
802.3 specification, you need to eliminate the collisions
that are inherent in Ethernet. This can be done by using
Full-Duplex. Each UTP port on TotalSwitch TP/8 Module
3.1

can operate in either Half- or Full-Duplex. By placing a
TotalSwitch TP/8 Module in each building, selecting FDX
on one of the TP ports, and attaching this link segment
to a Media Converter TP/FO, you can make long
distance (up to 40+ km in the case of TP/FO Single-
Mode/PLUS), Full-Duplex, 10 Mbps Ethernet fiber
connections between buildings, as illustrated in Figure
3.2.
Figure 3.2
PROBLEM 3: You have the same situation as Problem 2, but you
have four buildings you need to connect.
SOLUTION: As in the solution to Problem 2, using a
combination of a TotalSwitch Module and Media
Converter TP/FO, you can make multiple long distance
fiber runs from one central point. Simply install a
TotalSwitch FO/4 in one building and place a Media
Converter TP/FO on each link segment, as illustrated in
Figure 3.3.
Figure 3.3

Chapter 4
Technical Specifications
Fiber Optic Power Specifications
The maximum distance between any two fiber optic devices is
determined by a number of factors, including the TotalSwitch
Modules used in the configuration. The following table shows the
specifications for each of the available TotalSwitch Modules and will
assist in determining which TotalSwitch Module is best for your
installation.
1Distances listed are estimates and can vary with application. Distance limitations are determined by a
combination of fiber characteristics, number of splices and other physical parameters. Subtract 3 dB
from Power Loss Budget for 50/125µmulti-mode fiber.
2Values are averages and have been determined under factory conditions. Actual field application
values may vary.
3Half-Duplex (HDX) distances are limited by IEEE specifications.
Fiber Optic Cleaning Guidelines
Fiber Optic transmitters and receivers are extremely susceptible to
contamination by particles of dirt or dust, which can obstruct the
optic path and cause performance degradation. Good system
performance requires clean optics and connector ferrules.
1) Use fiber patch cords (or connectors, if you terminate your own
fiber) only from a reputable supplier; low quality components can
cause many hard-to-diagnose problems in an installation.
2) Dust caps are installed at the factory to ensure factory-clean
optical devices. These protective caps should not be removed
until the moment of connecting the fiber cable to the device.
Assure that the fiber is properly terminated, polished and free of
4.1

any dust or dirt and that the location is as free from dust and dirt
as possible.
3) Store spare caps in a dust free environment such as a sealed
plastic bag or box so that when reinstalled they do not introduce
any contamination to the optics.
4) Should it be necessary to disconnect the fiber device, reinstall the
protective dust caps.
5) If you suspect that the optics have been contaminated, alternate
between blasting with clean dry compressed air and flushing with
methanol to remove particles of dirt.
Electrostatic Discharge Precautions
Electrostatic discharge (ESD) can cause damage to your add-in
modules. Always observe the following precautions when installing or
handling an add-in module or any board assembly.
1) Do not remove unit from its protective packaging until you are
ready to install it.
2) Wear an ESD wrist grounding strap before handling any module
or component. If you do not have a wrist strap, maintain
grounded contact with the system unit throughout any procedure
requiring ESD protection.
WARNING! Integrated circuits and fiber optic components are
extremely susceptible to electrostatic discharge damage. Do not
handle these components directly unless you are a qualified service
technician and use tools and techniques that conform to accepted
industry practices.
3) Hold boards by the edges only; do not touch the electronic
components or gold connectors.
4) After removal, always place the boards on a grounded, static free
surface, ESD pad or in a proper ESD bag. Do not slide the board
over any surface.
