Switch Architecture

The TigerSwitch 10/100 employs a wire-speed, non-blocking switching
fabric. This permits simultaneous wire-speed transport of multiple packets
at low latency on all ports. This switch also features full-duplex capability
on all ports, which effectively doubles the bandwidth of each connection.

Switching Method

This switch uses store-and-forward switching to ensure maximum data
integrity. In store-and-forward switching mode, the entire packet must be
received into a buffer and checked for validity before being forwarded.
This prevents errors from being propagated throughout the network.

Management Options

This switch contains a comprehensive array of LEDs for “at-a- glance”
monitoring of network and port status. It also includes a built-in network
management agent that allows the switch to be managed in-band using
SNMP or RMON (Groups 1, 2, 3 and 9) protocols, with a Web browser, or
remotely via Telnet. The switch provides an RS-232 serial port (DB-9
connector) on the rear panel for out-of-band management. A PC may be
connected to this port
null-modem cable.

for configuration and monitoring out-of band via a

This switch provides a wide range of advanced features. Port-based and
tagged VLANs, plus support for automatic GVRP VLAN registration that
provides 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. Broadcast storm
control prevents broadcast traffic storms from engulfing the network. For
a detailed description, refer to the Management Guide.

ESCRIPTION OF HARDWARE

Description of Hardware

10BASE-T/100BASE-TX Ports

There are eight fixed 10BASE-T/100BASE-TX RJ-45 ports on the switch.
Because these 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.

Each of these ports support auto-negotiation, so the optimum
transmission mode (half or full duplex) and data rate (10/100 Mbps)
can be selected automatically. Each port also supports IEEE 802.3x
auto-negotiation of flow control, so the switch can automatically
prevent port buffers from becoming saturated.

Note: If a device connected to one of these ports does not support

auto-negotiation, the communication mode of that port can be
configured manually.

LANNING

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.

2

A switch can be easily configured in any Ethernet or Fast Ethernet
network to significantly boost bandwidth while using conventional cabling
and network cards.

Application Examples

The TigerSwitch 10/100 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 10/100 is an excellent choice for mixed Ethernet and
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 10/100 to an
Ethernet or Fast Ethernet hub or switch.

In the figure below, the TigerSwitch 10/100 is operating as a collapsed
backbone for a small LAN. It is providing dedicated 20 Mbps full-duplex
connections to workstations and 200 Mbps full-duplex connections to
power users and servers.

PPLICATION EXAMPLES

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 one specific group or to all 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 standard
connectivity rules for Ethernet and Fast 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.

PPLICATION NOTES

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 jamming packets from
being propagated throughout the hub.

3. For network applications that require routing between dissimilar

network types, you can attach the TigerSwitch 10/100 units directly to
a router.

Selecting a Site

TigerSwitch 10/100 units can be mounted 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 (32 to
122 °F) 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

WITCH

◆ Make sure twisted-pair cable is always routed away from power lines,

fluorescent lighting fixtures and other sources of electrical
interference, such as radios and transmitters.

◆ Make sure that a separate grounded power outlet that provides 100 to

240 VAC, 50 to 60 Hz, is within 2.44 m (8 ft) of each device and is
powered from an independent circuit breaker. As with any equipment,
using a filter or surge suppressor is recommended.

Connecting Network Devices

The TigerSwitch 10/100 is designed to interconnect multiple segments
(or collision domains). It may be connected to network cards in PCs and
servers, as well as to hubs, switches or routers.

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.

Twisted-Pair Devices

Each device requires an unshielded twisted-pair (UTP) cable with RJ-45
connectors at both ends. Use Category 5 for 100BASE-TX connections,
and Category 3, 4 or 5 for 10BASE-T connections.

Cabling Guidelines

The RJ-45 ports on the switch support automatic MDI/MDI-X operation,
so you can use standard straight-through twisted-pair cables to connect to
any other network device (PCs, servers, switches, routers, or hubs).

See Appendix B for further information on cabling.

Connecting to PCs, Servers, Hubs and Switches

1. Attach one end of a twisted-pair cable segment to the device’s RJ-45
connector.

Figure 4-1. Making Twisted-Pair Connections

2. If the device is a network card and the TigerSwitch 10/100 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. Otherwise, attach the
other end to an available port on the switch.

Make sure each 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 each connection is made, the green Link LED (on the TigerSwitch
10/100) corresponding to each port will light to indicate that the
connection is valid.

ROUBLESHOOTING

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, 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. 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.

Twisted-Pair Cable and Pin 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.

For 100BASE-TX/10BASE-T connections, a twisted-pair cable must have
two pairs of wires. Each wire pair is identified by two different colors. For
example, one wire might be red and the other, red with white stripes. Also,
an RJ-45 connector must be attached to both ends of the cable.

Caution: Each wire pair must be attached to the RJ-45 connectors in a

specific orientation. (See “Cabling Guidelines” on page 4-2 for
an explanation.)

Figure B-1 illustrates how the pins on the RJ-45 connector are numbered.
