Introduction

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.
The switch also features full-duplex capability on all ports, which effectively doubles
the bandwidth of each connection.
This switch uses store-and-forward switching to ensure maximum data integrity.
With store-and-forward switching, 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.
Network Management Options
With a comprehensive array of LEDs, the switch provides “at a glance” monitorin g of
network and port status. The switch can be managed over the net work with a web
browser or Telnet application, or via a direct connection to the console port. The
switch includes a built-in network management agent that allows it to be managed
in-band using SNMP or RMON (Groups 1, 2, 3, 9) protocols. It also has 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 serial cable. (See Appendix B for wiring options.)
For a detailed description of the management features, refer to the Management
Guide.
for configuration and monitoring out-of-band via a
Description of Hardware
10BASE-T/100BASE-TX Ports
The switch contains eight 10BASE-T/100BASE-TX RJ-45 ports. All 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-1.)
Each of these ports support auto-negotiation, so the optimu m tr ansmission mode
(half or full duplex), and data ra te (10 o r 100 Mbp s) ca n be sel ected aut omatic all y. If
a device connected to one of these ports does not support auto-negotiation, the
communication mode of that port can be configured manually.
Each port also supports IEEE 802.3x auto-negotiation of flow control, so the switch
can automatically prevent port buffers from becoming saturated.

Description of Hardware
1000BASE-T/SFP Ports
These are combination Gigabit RJ-45 ports with shared Small Form Factor
Pluggable (SFP) transceiver slots. If an SFP transceiver (purchased separately) is
installed in a slot and has a valid link on the port, the associated RJ-45 port is
disabled.
The 1000BASE-T RJ-45 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 “1000BASE-T Pin Assignments” on page B-3.)
Port and System Status LEDs
The switch includes a display panel for key system and port indications that simplify

Introduction

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 distance between end
stations is limited by a maximum 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 thi s
limitation.
A switch can be easily configured in any Ethernet, Fast Ethernet, or Gigabit Et hernet
network to significantly boost bandwidth while using conventional cabling and
network cards.

Application Examples
The switch is not only designed to segment your network, but also to provide a wi de
range of options in setting up network connections. Some typi cal applications are
described below .
Collapsed Backbone
The switch is an excellent choice for mixed Ethernet, Fast Ethernet, and Gigabit
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 f urth er expansion, just connect to
another hub or switch using one of the Fast Ethernet ports built into the front panel
or a Gigabit Ethernet port on a plug-in SFP transceiver.
In the figure below , t he switch i s operating as a colla psed backbone for a small L AN.
It is providing dedicated 10 Mbps full-duplex connections to workstations, 100 Mbps
full-duplex connections to power users, and 1 Gbps full-duplex connections to
servers.

With 8 1000 Mbps parallel bridging ports (i.e., 8 distinct collision domains), this
switch can function as an efficient bridged node that is ideal for a meeting room
environment. Zero noise makes the switch inobtrusive for such a setting.
In the figure below, the SMC6110L2 is connected to a central wiring closet via a
1000BASE-SX connection. The 1000BASE-T RJ-45 ports on the switch are
providing 10/100 Mbps full-duplex connections for PCs and notebooks.

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 hal f-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 singl e switched l ink sh ould
not exceed:
• 1000BASE-SX: 550 m (1805 ft) for multimode fiber.
• 1000BASE-LX: 5 km (3.1 miles) for single-mode fiber.
• 1000BASE-LH: 70 km (43.5 miles) for single-mode fiber.
However, power budget constraints must also be considered when calculating
the maximum cable length for your specific environment.

Chapter 3: Installing the Switch
Selecting a Site
Switch 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 (32 to 122 °F) and its
humidity within 10% to 90%, 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 t wisted-pair cable is al ways routed away from power lines, fluorescent
lighting fixtures and other sources of electrical interference, such as radios and
transmitters.
• Make sure that the unit is connected to a separate grounded power outlet that
provides 100 to 240 VAC, 50 to 60 Hz, is wit hin 2 m (6. 6 fee t) of each device and
is powered from an independent circuit breaker. As with any equipment, using a
filter or surge suppressor is recommended.
Ethernet Cabling
To ensure proper operation when i nstalli ng the switch int o a network, make sure that
the current cables are suitable for 10BASE-T, 100BASE-TX or 1000BASE-T
operation. Check the following criteria against the current installation of your
network:
• Cable type: Unshielded twisted pair (UTP) or shielded twisted pair (STP) cables
with RJ-45 connectors; Category 3 or better for 10BASE-T, Category 5 or better
for 100BASE-TX, and Category 5, 5e or 6 for 1000BASE-T.
• Protection from radio frequency interference emissions
• Elect rical surge suppression
• Separat ion of electrical wires (switch related or other) and electromagnetic fields
from data based network wiring
• Safe connections with no damaged cables, connectors or shields

The SFP slots support the following optional SFP transceivers:
• 1000BASE-SX
• 1000BASE-LX
• 1000BASE-LH
To install an SFP transceiver, do the following:
1. Consider network and cabling requirements to select an appropriate SFP
transceiver type.
2. Insert the transceiver with the optical connector facing outward and the slot
connector facing down. Note that SFP transceivers are keyed so they can only
be installed in one orientation.
3. Slide the SFP transceiver into the slot until it clicks into place.
Note: SFP transceivers are hot-swappable. The switch does not need to be powered off
before installing or removing a transceiver. However, always first disconnect the
network cable before removing a transceiver.
Note: SFP transceivers are not provided in the switch package.
Connecting to a Power Source
To connect a switch to a power source:
1. Insert the power cable plug directly into the AC socket located at t he back of the
switch.
Figure 3-6 Power Socket
2. Plug the other end of the cable into a grounded, three-pin, AC power source.
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.
3. Check the front-panel LEDs as the device is powered on to be su re the Power
LED is lit. If not, check that the power cable is correctly plugged in.

Chapter 4: Making Network Connections
Connecting Network Devices
The switch is designed to be connected to 10 or 100 Mbps network cards in PCs and
servers, as well as to other switches and hubs. It may also be connected to remote
devices using optional 1000BASE-SX, 1000BASE-LX, or 1000BASE-LH SFP
transceivers.
Twisted-Pair Devices
Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors
at both ends. Use Category 5, 5e or 6 cable for 1 000BASE-T connections, Category
5 or better for 100BASE-TX connections, and Category 3 or better for 10BASE-T
connections.
Cabling Guidelines
The RJ-45 ports on the switch support automatic MDI/ MDI-X pinout confi guration, 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.
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.

2. If the device is a network card and the switch is in the wiring closet, attach the
other end of the cable segment to a mo dular wall outl et that is con nected to th e
wiring closet. (See the section “Network Wiring Connections.”) 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: 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 each connection is made, the Link LED (on the switch) corresponding to
each port will light green (1000 Mbps) or amber (10/100 Mbps) to indicate that
the connection is valid.

Fiber Optic SFP Devices
An optional Gigabit SFP transceiver (1000BASE-SX, 1000BASE-LX or
1000BASE-LH) can be used for a backbone connection between switches, or for
connecting to a high-speed server.
Each single-mode fiber port requires 9/125 micron single-mode fi ber optic cable with
an LC connector at both ends. Each multimode fiber optic port requires 50/125 or
62.5/125 micron multimode fiber optic cabling with an LC connector at both ends.

The 1000BASE-SX, 1000BASE-LX, 1000BASE-LH 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 t he fiber type as listed
under “1000 Mbps Gigabit Ethernet Collision Domain” on page 4-6.
Connectivity Rules

When adding hubs (repeaters) to your network, please follow the connectivity rules
listed in the manuals for these products. 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.
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. Howev er, it is
recommended that for all critical connections, or any new cable ins tallations,
Category 5e (enhanced Category 5) or Category 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 802.3-2005 standards.

Cable Labeling and Connection Records
Cable Labeling and Connection Records
When planning a network installation, it is essential to label the opposing ends of
cables and to record where each cable is connected. Doing so will enable you to
easily locate inter-connected devices, isolate faults and change your topology
without need for unnecessary time consumption.
To best manage the physical implementations of your network, follow these
guidelines:
• Clearly label the opposing ends of each cable.
• Using your building’s floor plans, draw a map of the location of all
network-connected equipment. For each piece of equipme nt, identi fy the dev ices
to which it is connected.
• Note the length of each cable and the maximum cable length supported by the
switch ports.
• For ease of understanding, use a location-based key when assigning prefi xes to
your cable labeling.
• Use sequential numbers for cables that originate from the same equipment.
• Differentiate between racks by naming accordingly.
• Label each separate piece of equipment.
• Displa y a copy of your equipment map, including keys to a ll abbreviations at ea ch
equipment rack.

Diag LED is Amber • Power cycle the switch to try and clear the condition.
• If the condition does not clear, contact your dealer for assistance.
Link LED is Off • Verify that the switch and attached device are powered on.
• Be sure the cable is plugged into both the swit ch and corresponding device.
• If the switch is installed in a rack, check the connections to the punch-down
block and patch panel.
• Verify that the proper cable type is used and its length does not exceed
specified limits.
• Check the adapter on the attached device and cable connections for
possible defects. Replace the defective adapter or cable if necess ary.
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. If you still cannot isolate
the problem, 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.

Troubleshooting
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 tools. 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
For 10/100BASE-TX connections, the twisted-pair cable must have two pairs of
wires. For 1000BASE-T connections the twisted-pair cable must have four pairs of
wires. Each wire pair is identified by two different colors. For example, one wire
might be green and the other, green with white stripes. Also, an RJ-45 connector
must be attached to both ends of the cable.
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.

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 spec ified 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 to Run 1000BASE-T
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 and
correct the problem:
1. Replace any Category 5 patch cables with high-performance Category 5e or
Category 6 cables.
2. Reduce the number of connectors used in the link.
3. Reconnect some of the connectors in the link.
Fiber Standards
The current TIA (Telecommunications Industry Association) 568-A specification on
optical fiber cabling consists of o ne recognized cable typ e for horizont al subsys tems
and two cable types for backbone subsystems.
Horizontal 62.5/125 micron multimode (two fibers per outlet).
Backbone 62.5/125 micron multimode or single-mode.
TIA 568-B will allow the use of 50/125 micron multimode optical fiber in both the
horizontal and backbone in addition to the types listed above. All optical fiber
components and installation practices must meet applicable building and safety
codes.

Collision
A condition in which packets transmitted over the cable interfere
Their interference makes both signals unintelligible.
with each other.
Collision Domain
Single CSMA/CD LAN segment.
CSMA/CD
CSMA/CD (Carrier Sense Multiple Access/Collision Detect) is the communication
method employed by Ethernet, Fast Ethernet, and Gigabit Ethernet.
End Station
A workstation, server, or other device that does not forward traffic.
Ethernet
A network communication system developed and standardized by DEC, Intel, and
Xerox, using baseband transmission, CSMA/CD access, logical bus topology, and
coaxial cable. The successor IEEE 802.3 standard provides for int egration into the
OSI model and extends the physical layer and media with repeaters and
implementations that operate on fiber, thin coa x a nd twisted-pair cable.
Fast Ethernet
A 100 Mbps network communication system based on Ethernet and the CSMA/CD
access method.
Full Duplex
Transmission method that allows two network devices to transmit and receive
concurrently, effectively doubling the band width of that link.
Gigabit Ethernet
A 1000 Mbps network communication system based on Ethernet and the CSMA/CD
access method.
IEEE
Institute of Electrical and Electronic Engineers.
IEEE 802.3
Defines carrier sense multiple access with collision detection (CSMA/CD) access
method and physical layer specifications.

LAN Segment
Separate LAN or collision domain.
LED
Light emitting diode used for monitoring a device or network condition.
Local Area Network (LAN)
A group of interconnected computer and support devices.
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.
Modal Bandwidth
Bandwidth for multimode fiber is referred to as modal bandwidth because it varies
with the modal field (or core diameter) of the fiber. Modal bandwidth is specified in
units of MHz per km, which indicates the amoun t of bandwid th supported by t he fiber
for a one km distance.
Network Diameter
Wire distance between two end stations in the same collision domain.
Redundant Power Supply (RPS)
A backup power supply unit that automatically takes over in case the primary po wer
supply should fail.

Telecommunications Industry Association
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, allowing users to share
information and resources as though located on the same LAN.
