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.

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.

Network Management Module

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 full-

handshaking 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.)

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:

•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.

•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.

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.

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.

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.

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.

Figure 2-4. Making VLAN Connections

Note: When connecting to a switch that does not support IEEE

802.1Q VLAN tags, use untagged ports.

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).

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.

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.

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.

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.

Figure 4-1. Making SC Port Connections

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.

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.

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.

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.

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.

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)

The table below shows the 1000BASE-T MDI and MDI-X port

pinouts. These ports require that all four pairs of wires be

connected. Note that for 1000BASE-T operation, all four pairs of

wires are used for both transmit and receive.

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

Pin MDI Signal Name MDI-X Signal Name

1 Transmit Data plus (TD1+) Transmit Data plus (TD2 +)

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.

IEEE 802.1D

Specifies a general method for the operation of MAC bridges,

including the Spanning Tree Protocol.

IEEE 802.1Q

VLAN Tagging—Defines Ethernet frame tags which carry VLAN

information. It allows switches to assign endstations to different

virtual LANs, and defines a standard way for VLANs to

communicate across switched networks.

IEEE 802.3

Defines carrier sense multiple access with collision detection

(CSMA/CD) access method and physical layer specifications.

Glossary-4

IEEE 802.3ab

Defines CSMA/CD access method and physical layer specifications

for 1000BASE-T Gigabit Ethernet.

IEEE 802.3u

Defines CSMA/CD access method and physical layer specifications

for Fast Ethernet.

IEEE 802.3x

Defines Ethernet frame start/stop requests and timers used for

flow control on full-duplex links.

IEEE 802.3z

Defines CSMA/CD access method and physical layer specifications

for 1000BASE Gigabit Ethernet.

LAN Segment

Separate LAN or collision domain.

LED

Light emitting diode used for monitoring a device or network

condition.

Link Segment

Length of twisted-pair or fiber cable joining a pair of repeaters or a

repeater and a PC.

Local Area Network (LAN)

A group of interconnected computer and support devices.

Glossary-5

Media Access Control (MAC)

A portion of the networking protocol that governs access to the

transmission medium, facilitating the exchange of data between

network nodes.

MIB

An acronym for Management Information Base. It is a set of

database objects that contains information about the device.

MII

Media Independent Interface, the standard interface for Fast

Ethernet—similar to the AUI interface for traditional Ethernet.

Network Diameter

Wire distance between two end stations in the same collision

domain.

RJ-45 Connector

A connector for twisted-pair wiring.

Redundant Power Supply (RPS)

A backup power supply that automatically takes over in case the

primary power supply should fail.

Spanning Tree Protocol (STP)

A technology that checks your network for any loops. A loop can

often occur in complicated or backup linked network systems.

Spanning Tree detects and directs data along the shortest available

path, maximizing the performance and efficiency of the network.

Switched Ports

Ports that are on separate collision domains or LAN segments.

Glossary-6

Transmission Control Protocol/Internet Protocol (TCP/IP)

Protocol suite that includes TCP as the primary transport protocol,

and IP as the network layer protocol.

UTP

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.
