CHAPTER 1
ABOUT THE
TIGERSWITCH 100
Overview
SMC’s TigerSwitch™ 100 is a stackable switch with 24 100BASE-FX
VF-45 ports, plus two slots for optional slide-in 100BASE-FX or
1000BASE-X modules. One of these slots can also be used for an
optional stacking module that allows you attach up to four switches
to a 9.6 Gbps high-speed backplane. There is also an SNMP-based
Network Management Module installed in the rear panel. This
module supports both in-band and out-of-band access for managing
the switch and the attached stack. (Note that a switch stack, or a
switch in a standalone configuration, must have Network
Management Module installed to enable all ports. The base unit
alone has all ports disabled by default.)

Switch Architecture
The TigerSwitch employs a high-speed switching fabric. This design
allows for simultaneous transport of multiple packets at low latency
on all ports. It also uses store-and-forward switching to ensure
maximum data integrity. In this mode, the entire packet must be
received into a port buffer and checked for validity before being
forwarded. This prevents errors from being propagated throughout
the network. This switch also features full-duplex capability on all
ports, which effectively doubles the bandwidth of each connection.
This TigerSwitch can be used in a standalone configuration, or can
be stacked up to four high to form a single logical switch with up to
104 ports. When stacked, the 9.6 Gbps stack backplane provides
enough bandwidth for the most demanding environment. Moreover,
you can use a 100 Mbps single-mode fiber module for connecting to
a remote site, or a Gigabit module for a high-speed backbone
connection.

1-2

ABOUT THE TIGERSWITCH 100
Management Options
This switch contains a comprehensive array of LEDs for
“at-a-glance” monitoring of network and port status. It also
includes a Network Management Module that allows the entire
stack to be managed in-band via SNMP or RMON (Groups 1, 2, 3
and 9) protocols, with a Web browser, or remotely via Telnet. The
switch also provides a serial port on the rear panel for out-of-band
management.
Note: Only one Network Management Module must be installed
in the stack for the current firmware release.

Description of Hardware
100BASE-FX VF-45 Ports
These ports are VF-45 multimode fiber ports that can be connected
to workstations and servers with 62.5/125 micron or 50/125 micron
multimode fiber cable.
Each of these ports support half- and full-duplex operation at 100
Mbps. Note that 100BASE-FX ports do not support
auto-negotiation of duplex mode, so this has to be configured
manually. However, the ports do support IEEE 802.3x
auto-negotiation of flow control, so the switch can automatically
prevent port buffers from becoming saturated.

Figure 1-5. Network Management Module
This switch includes a Network Management Module on the rear
panel. This module can manage the switch and the attached stack.
It offers a variety of management options, including SNMP, RMON
and a Web-based interface. This module also includes an RS-232
port for out-of-band management. This is an RS-232 serial port
with a DB-9 connector. A PC may be connected to this port for
configuration and monitoring purposes out-of band via a fullhandshaking null modem cable. You can also make a remote
connection to this port via modems. This allows you to access the
out-of-band interface. (See Apendix B for a description of wiring
options.)
The Network Management Module provides a wide range of
advanced performance-enhancing features. Multicast filtering
provides support for real-time network applications. Port-based
and tagged VLANs provide traffic security and efficient use of
network bandwidth. QoS priority queueing ensures the minimum
delay for moving real-time multimedia data across the network.
Flow control eliminates the loss of packets due to bottlenecks

caused by port saturation. And broadcast storm control prevents
broadcast traffic storms from engulfing the network.
Some of this switch’s advanced features are described below. For a
detailed description, refer to the Management Guide.
Spanning Tree Protocol
The TigerSwitch 100 supports IEEE 802.1D Spanning Tree
Protocol. This protocol adds a level of fault tolerance by allowing
two or more redundant connections to be created between a pair
of LAN segments. When there are multiple physical paths between
segments, this protocol will choose a single path and disable all
others to ensure that only one route exists between any two
stations on the network. This prevents the creation of network
loops. However, if the chosen path should fail for any reason, an
alternate path will be activated to maintain the connection.
The default setting for the Spanning Tree Protocol is “enabled.”
This protocol may be configured out-of-band via the serial console
port, or in-band via the Web interface, Telnet, or SNMP network
management software.
VLANs
The TigerSwitch 100 supports up to 256 VLANs. A Virtual LAN is a
collection of network nodes that share the same collision domain
regardless of their physical location or connection point in the
network. By segmenting your network into VLANs, you can:

1-6

•

Eliminate broadcast storms which severely degrade
performance in a flat network.

•

Simplify network management for node changes/moves by
remotely configuring VLAN membership for any port, rather
than having to manually change the node’s IP address.

ABOUT THE TIGERSWITCH 100
•

Provides data security by restricting all traffic to the originating
VLAN, except where a connection has been configured
between separate VLANs using a router or Layer 3 switch.

Multicast Switching
Specific multicast traffic can be assigned to its own VLAN to ensure
that it does not interfere with normal network traffic and to
guarantee real-time delivery by setting the required priority level
for the designated VLAN. The switch uses IGMP Snooping and
IGMP to manage multicast group registration.
Traffic Priority
This switch provides Quality of Service (QoS) by prioritizing each
packet based on the required level of service, using two distinct
categories with Weighted Fair Queuing. It uses IEEE 802.1p and
802.1Q tags to prioritize incoming traffic based on input from the
end-station application. These functions can be used to provide
independent priorities for delay-sensitive data and best-effort data.

CHAPTER 2
NETWORK PLANNING
Introduction to Switching
A network switch allows simultaneous transmission of multiple
packets via non-crossbar switching. This means that it can partition
a network more efficiently than bridges or routers. The switch has,
therefore, been recognized as one of the most important building
blocks for today’s networking technology.
When performance bottlenecks are caused by congestion at the
network access point (such as the network card for a high-volume
file server), the device experiencing congestion (server, power
user or hub) can be attached directly to a switched port. And, by
using full-duplex mode, the bandwidth of the dedicated segment
can be doubled to maximize throughput.
When networks are based on repeater (hub) technology, the
maximum distance between end stations is limited. For Ethernet,
there may be up to four hubs between any pair of stations; for Fast
Ethernet, the maximum is two. This is known as the hop count.
However, a switch turns the hop count back to zero. So
subdividing the network into smaller and more manageable
segments, and linking them to the larger network by means of a
switch, removes this limitation.
A switch can be easily configured in any Ethernet or Fast Ethernet
network to significantly boost bandwidth while using conventional
cabling and network cards.

NETWORK PLANNING

Sample Applications
The TigerSwitch 100 is not only designed to segment your
network, but also to provide a wide range of options in setting up
network connections. Some typical applications are described
below.

Collapsed Backbone
The TigerSwitch 100 is an excellent choice for mixed Fast Ethernet
installations where significant growth is expected in the near
future. You can easily build on this basic configuration, adding
direct full-duplex connections to workstations or servers. When
the time comes for further expansion, just cascade the TigerSwitch
to a Fast Ethernet hub or switch, add another TigerSwitch to the
stack, or link to another workgroup using a Gigabit connection.
In the figure below, the TigerSwitch 100 is operating as a collapsed
backbone for a small LAN. It is providing dedicated 200 Mbps
full-duplex connections to workstations and servers.

Central Wiring Closet
With up to 104 ports in a stack (i.e., 104 distinct segments), the
TigerSwitch 100 can collapse a complex network down into a
single efficient bridged node, increasing overall bandwidth and
throughput.
In the figure below, the VF-45 ports on the TigerSwitch stack are
providing 100 Mbps connectivity for up to 96 end nodes. In
addition, the switch is also connecting servers at 2 Gbps.

Remote Connections with Fiber Cable
Fiber optic technology allows for longer cabling than any other
media type (up to 10 kilometers for 100 Mbps single-mode fiber at
full duplex, or up to 5 kilometers for 1 Gbps fiber). The
TigerSwitch can serve as a collapsed backbone, providing direct
connectivity for a widespread LAN. The 100 Mbps single-mode
fiber module can be used to interconnect remote Fast Ethernet
segments. While the Gigabit module can be used for a high-speed
connection between floors in the same building, or to connect to
other buildings in a campus setting. The figure below illustrates a
TigerSwitch 100 stack connecting multiple segments with fiber
cable.

NETWORK PLANNING
Making VLAN Connections
VLANs can be based on port groups, or each data frame can be
explicitly tagged to identify the VLAN group it belongs to. When
using port-based VLANs, ports can either be assigned to any
number of groups. Port-based VLANs are suitable for small
networks. A single switch can be easily configured to support
several VLAN groups for various organizational entities (such as
Finance and Marketing).
When you expand port-based VLANs across several switches, you
need to make a separate connection for each VLAN group. This
approach is, however, inconsistent with the Spanning Tree
Protocol, which can easily segregate ports that belong to the same
VLAN. When VLANs cross separate switches, it is therefore better
to use VLAN tagging. This allows you to assign multiple VLAN
groups to the “trunk” ports (that is, tagged ports) connecting
different switches.

Connectivity Rules
When adding hubs (repeaters) to your network, please follow the
connectivity rules listed below for Ethernet, Fast Ethernet, or
Gigabit Ethernet. However, note that because switches break up
the path for connected devices into separate collision domains,
you should not include the switch or connected cabling in your
calculations for cascade length involving other devices.

Application Notes
1. Full-duplex operation only applies to point-to-point access
(such as when a switch is attached to a workstation, server or
another switch). When the switch is connected to a hub, both
devices must operate in half-duplex mode.
2. When a switch is connected to a hub or any kind of shared
media, remember to turn off back pressure to prevent the
attached port from being frequently partitioned due to the
jamming packets.
3. For network applications that require routing (such as when
interconnecting dissimilar network types or distinct VLANs),
you may have to attach the TigerSwitch 100 units directly to a
router or Layer 3 switch (such as the SMC6724L3).

INSTALLING

CHAPTER 3
THE SWITCH

Selecting a Site
TigerSwitch 100 units can be mounted in a standard 19-inch
equipment rack or on a flat surface. Be sure to follow the
guidelines below when choosing a location.
◆

The site should:
•

be at the center of all the devices you want to link and near
a power outlet.

•

be able to maintain its temperature within 0° to 50° C and
its humidity within 5% to 95%, non-condensing

•

provide adequate space (approximately two inches) on all
sides for proper air flow

•

be accessible for installing, cabling and maintaining the
devices

•

allow the status LEDs to be clearly visible

◆

Make sure twisted-pair cable is always routed away from power
lines, fluorescent lighting fixtures and other sources of electrical
interference, such as radios, transmitters, etc.

◆

Make sure that a separate grounded power outlet that provides
100 to 240 VAC, 50 to 60 Hz, is within 8 feet of each device and
is powered from an independent circuit breaker. As with any
equipment, using a filter or surge suppressor is recommended.

Connecting to a Power Source
To connect a device to a power source:
Note: It is recommended that the switches be stacked before
being connected to a power source. However, a device can
be added to the top or bottom of a stack that is on and
operating without first powering down the stack. Be sure to
stack the new device before connecting it to a power
source. All switches in a stack must be powered on to allow
traffic to pass across the stack’s backplane.
To connect each device to a power source:
1. Insert the power cable plug directly into the receptacle located
at the back of the device.

Figure 3-6. Power Receptacle
2. Plug the other end of the cable into a grounded, 3-pin socket.
Note: For International use, you may need to change the AC line
cord. You must use a line cord set that has been approved
for the receptacle type in your country.

MAKING NETWORK
CONNECTIONS
Connecting Network Devices
The TigerSwitch 100 is designed to interconnect multiple segments
(or collision domains). It may be connected to 100 Mbps network
cards in PCs and servers, as well as to Fast Ethernet hubs, switches
or routers. It may also be connected to remote devices using the
optional 100BASE-FX or 1000BASE-X modules.
Note: Before connecting cables, you may want to first configure
the Spanning Tree Protocol to avoid network loops. Refer
to the Management Guide for more information.

4-1

MAKING NETWORK CONNECTIONS

VF-45 Fiber Connections
Each device requires a 62.5/125 micron or 50/125 micron
multimode fiber optic cable with VF-45 connectors at both ends.
1. Remove and keep the VF-45 port’s plastic cover. When not
connected to a fiber cable, the cover should be replaced to
protect the optics.
2. Check that the fiber terminators are clean. You can clean the
cable plugs using an appropriate VF-45 cleaning kit. Dirty fiber
terminators on fiber optic cables will impair the quality of the
light transmitted through the cable and lead to degraded
performance on the port.
3. Connect one end of the cable to the VF-45 port on the switch
and the other end to the VF-45 port on the other device. Since
VF-45 connectors are keyed, the cable can be attached in only
one orientation.
4. As each connection is made, check the Link LED on the
switch’s front panel for the corresponding port to be sure that
the connection is valid.
You can run a fiber link up to 2 km (1.24 mi.) in full-duplex mode,
and 412 m (1351 ft.) in half-duplex mode. However, note that
power budget and timing constraints must also be considered
when calculating the maximum cable length for your specific
environment.

4-2

MAKING NETWORK CONNECTIONS

SC Fiber Connections
An optional slide-in 100BASE-FX module may be used for
backbone and long distance connections. A 1000BASE-X module
may also be used for a backbone connection between switches, or
for connecting to a high-speed server.
Each multimode fiber optic port requires 50/125 or 62.5/125
micron multimode fiber optic cabling with an SC connector at both
ends. If you need to connect to a device with 62.5/125 micron
cable that has ST-type connectors, SMC provides an optional SC-ST
Converter (Part Number: 99-012034-091).
Each single-mode fiber port requires 9/125 micron single-mode
fiber optic cable with an SC connector at both ends.
Warning: This switch uses lasers to transmit signals over fiber
optic cable. The lasers are compliant with the
requirements of a Class 1 Laser Product and are
inherently eye safe in normal operation. However, you
should never look directly at a transmit port when it is
powered on.
1. Remove and keep the SC port’s rubber cover. When not
connected to a fiber cable, the rubber cover should be
replaced to protect the optics.
2. Check that the fiber terminators are clean. You can clean the
cable plugs by wiping them gently with a clean tissue or cotton
ball moistened with a little ethanol. Dirty fiber terminators on
fiber optic cables will impair the quality of the light transmitted
through the cable and lead to degraded performance on the
port.

4-3

MAKING NETWORK CONNECTIONS
3. Connect one end of the cable to the SC port on the switch and
the other end to the SC port on the other device. Since SC
connectors are keyed, the cable can be attached in only one
orientation.

4. As a connection is made, check the Activity LED on the
switch’s front panel for the corresponding module to be sure
that the connection is valid.
Note: If you use the optional SC-ST Converter, be sure to connect
the converter’s Tx (Rx) port to the Rx (Tx) port on the other
device.
The 100BASE-FX fiber optic ports operate only at 100 Mbps, full
duplex. You can run a single-mode fiber link up to 6.21 miles (10
kilometers). However, note that power budget constraints must
also be considered when calculating the maximum cable length for
your specific environment.
The 1000BASE-SX fiber optic ports operate at 1 Gbps full duplex,
with auto-negotiation of flow control. The maximum length for
fiber optic cable operating at Gigabit speed will depend on the
fiber type as listed under “1000 Mbps Gigabit Ethernet Collision
Domain” on page 2-6.

MAKING NETWORK CONNECTIONS

1000BASE-T Twisted-Pair Connections
A 1000BASE-T connection requires a shielded or unshielded
twisted-pair (STP or UTP) cable with RJ-45 connectors at both
ends. For all connections, Category 5 or 5e (recommended) cable
is required with all four wire pairs connected. You should also test
the cable installation for IEEE 802.3ab compliance. See
“1000BASE-T Cable Requirements” on page B-4.

Cabling Guidelines
The RJ-45 port on the SMC6900GT module supports 1000, 100, and
10 Mbps Ethernet operation, with auto-negotiation of speed,
duplex mode, and flow control. Because 1000BASE-T ports
support automatic MDI/MDI-X operation, you can use
straight-through cables for all network connections to PCs or
servers, or to other switches or hubs.
Caution: Do not plug a phone jack connector into an
RJ-45 port. This will damage the switch. Use only
twisted-pair cables with RJ-45 connectors that conform to
FCC standards.

Connecting to PCs, Servers, Hubs and Switches
1. Attach one end of a twisted-pair cable segment to the device’s
RJ-45 connector.

MAKING NETWORK CONNECTIONS

Figure 4-2. Making Twisted-Pair Connections
2. If the device is a network card and the TigerSwitch is in the
wiring closet, attach the other end of the cable segment to a
modular wall outlet that is connected to the wiring closet (see
“Wiring Closet Connections” on the next page). Otherwise,
attach the other end to the port on the 1000BASE-T module.
Make sure the twisted pair cable does not exceed 100 meters
(328 ft.) in length.
Note: When connected to a shared collision domain (such as a
hub with multiple workstations), switch ports must be
set to half-duplex mode and back pressure flow control
disabled.
3. As the connection is made, the green Activity LED (on the
TigerSwitch) corresponding to the module port will start to
flash, indicating that the connection is valid and traffic is
passing through the port.

MAKING NETWORK CONNECTIONS
Wiring Closet Connections
Today, the punch-down block is an integral part of many of the
newer equipment racks. It is actually part of the patch panel.
Instructions for making connections in the wiring closet with this
type of equipment follows.
1. Attach one end of a patch cable to the port on the 1000BASE-T
module, and the other end to the patch panel.
2. If not already in place, attach one end of a cable segment to
the back of the patch panel where the punch-down block is
located, and the other end to a modular wall outlet.
3. Label the cables to simplify future troubleshooting.

TROUBLESHOOTING

Power and Cooling Problems
If the power indicator does not turn on when the power cord is
plugged in, you may have a problem with the power outlet, power
cord, or internal power supply. However, if the unit powers off
after running for a while, check for loose power connections,
power losses or surges at the power outlet, and verify that the fans
on the unit are unobstructed and running prior to shutdown. If
you still cannot isolate the problem, then the internal power
supply may be defective. In this case, contact SMC Technical
Support for assistance.

Installation
Verify that all system components have been properly installed. If
one or more components appear to be malfunctioning (such as the
power cord or network cabling), test them in an alternate
environment where you are sure that all the other components are
functioning properly.

In-Band Access
You can access the management agent in the switch from
anywhere within the attached network using Telnet, a Web
browser, or other network management software such as
EliteView. However, you must first configure the switch with a
valid IP address, subnet mask, and default gateway. If you have
trouble establishing a link to the management agent, check to see
if you have a valid network connection. Then verify that you
entered the correct IP address. Also, be sure the port through
which you are connecting to the switch has not been disabled. If it
has not been disabled, then check the network cabling that runs
between your remote location and the switch.

A-2

TROUBLESHOOTING
Note: You can configure the management agent to accept from
one to four simultaneous Telnet sessions. If the maximum
number of sessions already exists, an additional Telnet
connection will not be able to log into the system.

RJ-45 Port and Cable Assignments
CAUTION: DO NOT plug a phone jack connector into any RJ-45
port. Use only twisted-pair cables with RJ-45
connectors that conform with FCC standards.
The RJ-45 port on the SMC6900GT module supports 1000, 100,
and 10 Mbps Ethernet operation, with auto-negotiation of speed,
duplex mode, and flow control.

1000BASE-T Pin Assignments
1000BASE-T ports switch support automatic MDI/MDI-X operation,
so you can use straight-through cables for all network
connections to PCs or servers, or to other switches or hubs. In
straight-through cable, pins 1-8, at one end of the cable, are
connected straight through to pins 1-8 at the other end of the
cable.

Use 100-ohm Category 5 or 5e unshielded twisted-pair (UTP) or
shielded twisted-pair (STP) cable for 1000BASE-T connections.
Also be sure that the length of any twisted-pair connection does not
exceed 100 meters (328 feet).

B-3

CABLES
The table below shows the 1000BASE-T MDI and MDI-X port
pinouts. These ports require that all four pairs of wires be

1000BASE-T Cable Requirements
All Category 5 UTP cables that are used for 100BASE-TX
connections should also work for 1000BASE-T, providing that all
four wire pairs are connected. However, it is recommended that
for all critical connections, or any new cable installations, Category
5e (enhanced Category 5) cable should be used. The Category 5e
specification includes test parameters that are only
recommendations for Category 5. Therefore, the first step in
preparing existing Category 5 cabling for running 1000BASE-T is a
simple test of the cable installation to be sure that it complies with
the IEEE 802.3ab standards.

Cable Testing for Existing Category 5 Cable
Installed Category 5 cabling must pass tests for Attenuation,
Near-End Crosstalk (NEXT), and Far-End Crosstalk (FEXT). This

B-4

CABLES
cable testing information is specified in the ANSI/TIA/EIA-TSB-67
standard. Additionally, cables must also pass test parameters for
Return Loss and Equal-Level Far-End Crosstalk (ELFEXT). These
tests are specified in the ANSI/TIA/EIA-TSB-95 Bulletin, “The
Additional Transmission Performance Guidelines for 100 Ohm
4-Pair Category 5 Cabling.”
Note that when testing your cable installation, be sure to include
all patch cables between switches and end devices.

Adjusting Existing Category 5 Cabling
If your existing Category 5 installation does not meet one of the
test parameters for 1000BASE-T, there are basically three measures
that can be applied to try to correct the problem:
1. Replace any Category 5 patch cables with high-performance
Category 5e cables.
2. Reduce the number of connectors used in the link.
3. Reconnect some of the connectors in the link.

Console Port Pin Assignments
The DB-9 serial port on the switch’s rear panel is used to connect
to the switch for out-of-band console configuration. The on-board
menu-driven configuration program can be accessed from a
terminal, a PC running a terminal emulation program, or from a
remote location via a modem connection. The pin assignments

Unshielded twisted-pair cable.
Virtual LAN (VLAN)
A Virtual LAN is a collection of network nodes that share the same
collision domain regardless of their physical location or connection
point in the network. A VLAN serves as a logical workgroup with
no physical barriers, and allows users to share information and
resources as though located on the same LAN.
