Switch Architecture

The switch 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.

Auto-negotiation is used to select the optimal transmission speed and
communication mode for each connection. With store-and-forward
switching and flow control, maximum data integrity is always maintained,
even under heavy loading.

This switch includes two slots on the front panel for slide-in 1000BASE-T,
100BASE-FX, or 1000BASE-X (GBIC) modules. Cascade connections

The switch also supports a stacking module that can be installed into slot
M2. The stacking module allows up to eight units to be linked together and
managed from one unit using one IP address.

Management Options

This switch contains a comprehensive array of LEDs for “at-a-glance”
monitoring of network and port status. It also includes a management
agent that allows you to configure or monitor the switch using its
embedded management software, or via SNMP applications. To manage
the switch, you can make a direct connection to the RS-232 console port
(out-of-band), or you can manage the switch through a network
connection (in-band) using Telnet, the on-board Web agent, or
Windows-based network management software.

The management agent provides a wide range of advanced
performance-enhancing features. Port-based VLANs provide traffic
security and efficient use of network bandwidth. QoS priority queueing
ensures the minimum delay for moving real-time multimedia data through
the switch. Flow control eliminates the loss of packets due to bottlenecks
caused by port saturation. Port security is provided to filter unwanted
traffic from the switch.

For a detailed description of the switch’s advanced features, refer to the
Management Guide.

Description of Hardware

RJ-45 Ports

The switch base unit contains 24 10BASE-T/100BASE-TX RJ-45 ports.
All of these ports 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. (See “10BASE-T/100BASE-TX Pin
Assignments” on page B-2.)

Each of these ports support auto-negotiation, so the optimum
transmission mode (half or full duplex), and data rate (10 or 100 Mbps) can
be selected automatically, if this feature is also supported by the attached
device. If a device connected to one of these ports does not support
auto-negotiation, the correct speed will be sensed by the port, but the
transmission mode will default to half duplex.

Each port also supports auto-negotiation of flow control, so the switch
can automatically prevent port buffers from becoming saturated.

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 TigerStack III 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 TigerStack III 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 switch to an Ethernet or Fast
Ethernet hub or switch, or link to another workgroup using a Gigabit
connection.

In the figure below, the switch 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.

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..

ONNECTIVITY RULES

Connectivity Rules

When adding hubs (repeaters) to your network, please follow the standard
connectivity rules 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.

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. Avoid using flow control on a port connected to a hub unless it is
actually required to solve a problem. Otherwise back pressure jamming
signals may degrade overall performance for the segment attached to
the hub.

3. As a general rule the length of fiber optic cable for a single switched
100BASE-FX link should not exceed 2 km (1.24 miles) for multimode
fiber or 20 km (2.43 miles) for single-mode fiber.

However, power budget constraints must also be considered when
calculating the maximum cable length for your specific environment.

Connecting Network Devices

The TigerStack III 10/100 may be connected to 10 or 100 Mbps network
cards in PCs and servers, as well as to hubs and switches. It may also be
connected to remote devices using the optional fiber optic modules

Twisted-Pair Devices

Each device requires a shielded or unshielded twisted-pair (STP or UTP)
cable with RJ-45 connectors at both ends. For 1000BASE-T Category 5,
5e, or 6 cable is required, for 100BASE-TX connections, Category 5 cable
is required; for 10BASE-T, Category 3 or better cable can be used.

4

Cabling Guidelines

A twisted-pair connection between two ports must have a crossover of the
transmit and receive wires to be able to function. This crossover can be
implemented in either of the ports, or in the cable connecting them.

Network card ports in PCs and servers do not contain an internal wiring
crossover, these are known as straight-through (MDI) ports. Therefore,
most switch and hub ports implement a built-in crossover - known as fixed
crossover (MDI-X) ports - so that they can be connected to PCs and
servers using standard straight-through cable. Some switches and hubs also
have an MDI port, so that they can connect to another switch's/hub's

4-1

M

AKING NETWORK CONNECTIONS

MDI-X port using straight-through cable. To connect between two
switches/hubs that only have fixed MDI-X ports, the wiring crossover
must be implemented in the cable - known as a crossover cable.

The RJ-45 ports on the switch base unit support automatic MDI/MDI-X
operation, which means that they automatically detect the wiring in the link
and configure as MDI or MDI-X accordingly. So for these ports, you can
use standard straight-through twisted-pair cables to connect to any other
network device (PCs, servers, switches, hubs, or routers). However, note
that auto-negotiation must be enabled on these ports for automatic wiring
configuration to function properly.

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 an available port on the switch, 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.

IBER OPTIC DEVICES

Fiber Optic Devices

An optional slide-in 100BASE-FX module or 1000BASE-X (GBIC)
transceiver may be used for backbone and long distance connections. A
1000BASE-SX, 100BASE-LX, or 1000BASE-LH GBIC transceiver may
also be 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.

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, then the internal
power supply may be defective.

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.

Note: The management agent accepts up 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.

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 4-1 for
an explanation.)

Figure B-1 illustrates how the pins on the RJ-45 connector are numbered.
Be sure to hold the connectors in the same orientation when attaching the
wires to the pins.

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) or 6 cable
should be used. The Category 5e and 6 specifications include 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 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: 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 or 6 cables.

2. Reduce the number of connectors used in the link.

3. Reconnect some of the connectors in the link.
