Chapter 1: About the

TigerSwitch 10/100/1000

Overview

SMC’s TigerSwitch 10/100/1000 SMC8124PL2 is an intellig ent Layer 2 PoE switch
with 24 10/100/1000BASE-T ports, two of which are combination po rts

shared with two SFP transceiver slots (see Figure 1-1, Ports 23-24).
The switch includes an SNMP-base d m ana gement agent embedded on the main

board, which supports both in-band an d out - of -b and management access.
It can easily enhance your network w ith fu ll support for Spanning Tree Protocol,

multicast switching, and virtual LA N s. It br in gs order to poorly perfo rm ing networks
by segregating them into separate bro adc ast domains with IEEE 802.1Q compliant

Switch Architecture

This Gigabit Ethernet switch empl oys a wire-speed, non-blocking swit chi ng fa bric.
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 bandw idth o f ea ch connection.

For communica tions within the sam e VLAN, the switch us es st o re-and-forward
switching to ensure maximum data integrity. The entire packet must be received into

being propagated th ro ughout the network.

Power-over-Ethernet Capability

The switch’s 24 10/100/1000 Mbps ports support the IEEE 802.3af
Power-over-Eth er net (PoE) standard that ena bles DC power to be supplied to
attached devices us in g wi re s i n th e co nnecting Ethernet cab le . An y 802.3af
compliant device attached to a port can directly draw power from the switch over the
Ethernet cable without requiring its own separate power source. This capability gives
network administrators centralized power control for devices such as IP phones and
wireless access points, which trans lat es i nt o gr eater network av ai la bil ity.

For each attached 802.3af-complian t de vi ce , the switch automat ic al ly senses the
load and dynam ical l y su ppl i es the required pow er. The switch deli ver s power to a
device using wire pairs in the UTP or STP cable. Each port can provide up to 15.4 W
of power at the standard -48 VDC voltage.

Network device s such as IP phones, wireless access points, and netwo rk cam eras,
typically consume less than 10 W of pow er, so they are ideal for
Power-over-Eth er net applications.

Network Management Options

The switch contains a comprehensive array of LEDs for “at-a-glance” monitoring of
network and por t statu s. It also i ncludes a managem e nt agent that allows yo u to
configure or moni t or the swi tc h us in g i ts embedded manage m ent so ftware, or vi a
SNMP applications. To manage the switch, you can make a direct connecti on to the
console port (ou t-of - band), or you can ma nage it through a net work connection
(in-band) using Te lnet , the on-board web ag ent, or SNMP-bas ed network
management software.

For a detailed description of the switch’s advan ce d fe at ur es, refer to the
Management G ui de .

Description of Hardware

10/100/1000BASE-T Ports

The switch contains 24 RJ-45 ports that operate at 10 Mbps or 100 Mbps, half or full
duplex, or at 1000 Mbps, full duplex. Because all ports on the switch 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. (See “1000BASE-T Pin
Assignments” on page B-3.)

Chapter 2: Network Planning

Introduction to Switching

A network switch allows simultaneous transmission of multiple packets via
non-crossbar sw i tching. This means t hat it can partition a network more efficiently
than bridges or rout er s. The switch has, there f or e, been recognized as on e of th e
most important building blocks for today’s networking techn ol ogy.

When performance bottlenecks are caused by congestion at the network access
point (such as the net w or k c ar d fo r a high-volume file ser ve r) , the device
experiencing co ngestion (server, power user or hub ) c an be attached directly to a
switched port. A nd, by usi ng full-duplex mode , the bandwidth of the dedicated
segment can be doubled to maximiz e th ro ughput.

When networks ar e based on repeater (hub) technology, the distance between end
stations is limited by a ma xi m um hop count. Howev er, a switch turns the hop count
back to zero. So subdividing the networ k i nt o sm aller and more manageable
segments, and linking them to the larger network by means of a switch, removes this
limitation.

A switc h can be eas ily con figur ed i n any Ethe rnet , F ast Et her net, or Gi gabi t Et her net
network to signif icant l y boost bandwidth while usi ng conventional ca bl in g and
network cards.

Application Examples

The TigerSwitch 10/100/10 00 i s not only designed to seg m ent your network, but
also to provide a wide range of options in setting up network connections. Some
typical applications are describe d bel ow.

Collapsed Backbone

The TigerSwitch 10/100/10 00 i s an excellent choice for mixe d Et her net, Fast
Ethernet, and Gigabit Ethernet installation s where significant growth is expected in
the near future. In a basic stand-alone configuration, it can provide direct full-duplex
connections for up to 24 workstations or ser vers. You can ea sil y bui ld on this basic
configuration, adding direct full-duplex connections to workstations or servers. When
the time comes fo r fur th er expansion, just connec t to an ot her hub or switch usin g
one of the Gigabit Ethernet ports built into the front panel, or a Gigabit Ethernet port
on a plug-in SFP transcei ver.

Remote Connections with Fiber Cable

Fiber optic techno logy allows for longer cabling than any other media type. A
1000BASE-SX (MMF) link c an co nnect to a site up to 550 meters away, a
1000BASE-LX (SMF) link up to 5 km, and a 100 0BASE-ZX link up to 100 km. This
allows a switch to serve as a collapsed backbone, providing direct connectivity for a
widespread LAN.

A 1000BASE-SX SFP transceiver can be used for a high-speed connection between
floors in the same building. For long-haul connections, a 1000BASE-ZX SFP
transceiver ca n be used to reach another site up to 100 kilom et er s away.

Making VLAN Connections

This switch suppo rts VLAN s w h ic h can be used to organize any group of netw or k
nodes into separate br oadcast domai ns. VLANs confine broadcast tr affic to the
originating group, and can eliminate broadcast storms in large networks. This
provides a more secure and cleaner network environment.

VLANs can be based on untagged port groups, or traffic can be explicitly tagg ed t o
identify the VLAN group to which it belongs. Untagged VLANs can be used for small
networks attached to a sin gl e sw it ch. However, tagged VLANs should be used for
larger networks , and all th e VLANs assigned t o the i nt er -s w i tc h lin ks.

Application Notes

1. Full- duplex operation only applies to point-to- point access (s uch as when a
switch is attached to a workstation, server or another switch). When the switch
is connected to a hu b, bot h devices must op er at e in hal f -d uplex mode.

2. For network applications that require routing between dissimilar network types,
you can attach these switches direct ly to a m ulti-protocol rout er.

3. As a general rule, the length of fiber optic cable for a single switched link should
not exceed:

• 1000BASE-SX: 550 m (1805 ft) for multimode fiber

• 1000BASE-LX: 10 km (3.1 miles) for single-mode fiber

• 1000BASE-ZX: 80 km (62.1 miles) for single-mode fiber

However, power budget const ra in ts must also be considered w hen calculating the
maximum cable length for your specific environment.

is powered from an indepe ndent circuit breaker. As with any equipment, using a
filter or surge suppr essor is recommended.

Ethernet Cabling

To ensure proper operation when install ing t he switch in a network, m a k e sure that
the current cables are suitable for 10BASE- T, 100 BASE-TX or 1000BASE-T
operation. Chec k t he f ol low i ng criteria against th e cur r ent in stall at ion of your
network:

• Cable type: Unshielded twisted pair (UTP) or shielded twisted pair (STP) cables
with RJ-45 connectors; Category 3 or better for 10B ASE-T, Category 5 or better
for 100BASE-TX, and Category 5, 5e or 6 for 1000BASE-T.

• Protection from radio frequency interference emissions

• Electrical surge suppression

• Separation of electrical wires (switch related or other) and electromagnetic fields
from data based net w or k wi ring

• Safe connections with no damaged cab le s, connectors or shiel ds

Chapter 4: Making Network Connections

Connecting Network Devices

The TigerSwitch 10/100/1000 units are designed to interconnect multiple segments
(or collision domains). It can be connected to network cards in PCs and servers, as
well as to hubs, swi t ches or routers. It may also be conne ct ed to devices using
optional 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 1000BASE-T connections, Category
5 or better for 100BASE-TX connec tions, an d Category 3 or better for 10BASE-T
connections.

Power-over-Ethernet Connections

The PoE switch automatically detec ts an 80 2. 3a f- co m pl ia nt dev i ce by its
authenticated PoE signature and sen ses its requir ed load before turning on DC
power to the port. This detection mechanism prevents damage to other network
equipment that is not 802.3af compl iant .

Note: Power-over-Ethernet connections work with all existing Category 3, 4, 5, 5e or 6

network cabling, including patch cables and patch-panels, outlets, and other
connecting hardware, without requiring modification.

The switch delivers power to a device using wire pairs in the connecting UTP or STP
cable. The switc h can provide up to 15.4 W of pow er continuously on each port.
However, taking into account some power loss over the cable run, the amount of
power that can be deli ver ed to a terminal devi ce is 1 2. 95 W.

The switch control s th e po w er and data on a port independe nt ly. Power can be
requested from a de vi ce that already has a data link to the switch. A lso, th e sw i t ch
can supply power to a device even if the port’s data con nec tion has been disabl ed.
The power on a port is conti nuously monitore d by th e swi t ch and it will be turned off
as soon as a device connection is removed.

Cabling Guidelines

The RJ-45 ports on the switch support automatic MDI/MDI-X pinout configuration, so
you can use standar d st ra ig ht-t h rough twisted-pair cabl es to connect to any ot her
network device (PCs, servers, sw itches, routers, or hubs).

Making Network Connections

See Appendix B: for further information on cabling.

Caution: Do not plug a ph one jack connector in to an R J-45 port. This will
damage the switc h. U se onl y t w ist ed- 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 seg m ent t o th e device’s RJ-45
connector.

Figure 4 -1 Making Twisted-Pair Connections

2. If the device is a PC card and the switch 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 “Netwo r k Wiring Connections” on page 4-2.) Otherwise, attach the
other end to an avail abl e po rt on the sw i tch.

3. Make sur e each twisted pair cable does not exceed 100 meters (328 ft) in
length.

4. As each connection is made , the Li n k LED ( on t he switch) correspo nding to

connecting to a high-speed server.

Each single-mode fiber port requires 9/125 micron single-mode fiber 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.

Making Network Connections

Caution: 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.

Note: When selecting a fiber SFP device, considering safety, please make sure that it

can function at a temperature that is not less than the recommended maximum
operational temperature of the product. You must also use an approved Laser
Class 1 SFP transceiver.

Note: Bei der Wahl eines Glasfasertransceivers muß für die Beurteilung der

Gesamtsicherheit beachtet werden, das die maximale Umgebungstemperatur des
Transceivers für den Betrieb nicht niedriger ist als die für dieses Produkts. Der
Glasfasertransceiver muß auch ein überprüftes Gerät der Laser Klasse 1 sein.

1. Remo ve a nd keep the LC port’s rubber cover. When not connected to a fibe r
cable, the rubbe r co ver should be replac ed t o pr ot ect the optics.

2. Check th at the fiber terminators are cle an. You can clean the ca ble plugs by
wiping them gentl y w it h a cl ean tissue or cotton bal l m oi st en ed w i t h a little
ethanol. Dirty fib er ter m i nat or s on fiber cables will impair t he qu al i ty of the light
transmitted thro ugh the cable and lead t o degraded perform ance on the port.

3. Connect one end of the cable to the LC port on the switch and the other end to
the LC port on the other device. Since LC connectors are keyed , the cabl e can
be attached in only one or i entation.

1 Gbps full duplex. The m ax imum length for fibe r op tic c abl e operating at Gigab i t
speed will depend on the fiber type as listed under “1000 Mbps Gigabit Ethernet
Collision Domai n” on page 4- 5.

Connectivity Rules

When adding hu bs ( repeaters) to your net w or k, pl ea se f ol l ow th e co nnectivity 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 calcul ati ons for cascade le ngt h
involving other de vi ces.

1000BASE-T Cable Requirements

All Category 5 UTP cables that are used for 100 BASE-TX connections sh ou ld also
work for 1000BASE-T, providing that all four wire pairs are connected. However, it is
recommended t hat for all critical connections, or any new cable installation s ,
Category 5e (en han ced Category 5) or Cat egory 6 cable should be used. The
Category 5e spec i fica tion includes test para m et er s t hat ar e only recommendations
for Category 5. Therefore, the first step in preparing existing Cat egory 5 cabling for
running 1000BA SE- T is a si m pl e test of th e cable installation to be sure th at it
complies with the IE EE 802.3-2005 standards.

Cable Labeling and Connection Records

When planning a network installation, it is ess e n tial to label th e opposing ends of
cables and to record where each cable is connected. Doing so will enable you to
easily locate inter - connected device s, is ol at e faul ts an d change your topol ogy
without need for u nn ecessary time consumption.

To best manage the phy si cal implementations of y our net w ork, follow these
guidelines:

• Clearly label the opposi ng ends of each cable .

• Using your building’s floo r plans, draw a map of the location of all

network-connected equipment. For each piece of equipment, identify the devices
to which it is connected.

4-6

Cable Labeling and Connection Records

• Note the length of each cable and the maximum cable length supported by the
switch ports.

• For ease of understand in g, use a location-base d key when assigning prefixes to
your cable labeling.

• Use sequential numb er s for c abl es that originate from t he same equipment .

• Differentiate between racks by naming accordingly.

• Label each separate piece of equipment.

• Display a copy of your equipment map, including keys to all abbreviations at each
equipment rack.

Symptom Action

Power LED is Off • Check connections between the switch, the power cord, and the wall

outlet.

• Contact your dealer for assistance.

• Contact SMC Technical Support.

Power LED is Amber • Internal power supply has failed. Contact your local 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 switch and corresponding
device.

• 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 necessary.

Power and Cooling Problems

If the power indica to r do es not turn on when th e pow e r cord is plugged in, you may
have a problem with the power outlet, pow er cord, or internal power supply.
However, if the unit powers off after running for a while, check for loose power
connections, po w er lo sses or surges at the power outlet, and verify that the fans on
the uni t a re un obst ruc ted and r unni ng pr io r to s hut do wn. If y ou st ill ca nnot isol at e the
problem, then th e inte rn al pow er supply may be def ective.

Installation

Verify that all system componen ts hav e been properly installed. If one or more
components appear to be malfunctioning (such as the power cord or network
cabling), test them in an alter nat e environment whe re you ar e sur e th at all the oth er
components are functioning properly.

Troubleshooting

In-Band Access

You can acces s t he m anagement agent in the switch from anywhere within the
attached network using Telnet, a Web browser, or other network management
software tools. Ho wever, you must first configure the switch with a valid IP ad dr ess,
subnet mask, and def ault gateway. If you have trouble establishing a l in k to th e
management agent, check to se e if yo u have a valid network connection. Th en
verify that you entered the correct IP address. Also, be sure the port through which
you are connect in g to the sw i t ch has not been disab le d. If it has not been disabled,
then check the net w or k cabling that runs b etw een your remote loc at io n and the
switch.

Caution: The management agent can accept 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 th e system.

Appendix B: Cables

Twisted-Pair Cable and Pin Assignments

For 10BASE-T/100BASE- TX connections, a 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 id enti f ie d by two different colors. For exa m ple, one wire
might be green and th e ot her, green with white stripes. Also, an RJ-45 connector
must be attached to bot h en ds of the cable.

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

orientation.

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.

Figure B-1 illustrates how the pins on the RJ-45 connector are numbered. Be sure to
hold the connect ors in the sam e orientation when attach in g the w i re s t o th e pins.

10BASE-T/100BASE-TX Pin Assignments

Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45
connections: 10 0- ohm Category 3 or be tter cable for 10 Mbps con nections, or
100-ohm Category 5 or better cable for 100 Mbps connections. Also be sure that the
length of any twisted-pair connection does not exceed 100 meters (328 feet).

The RJ-45 ports on the switch base unit support automatic MDI/MDI-X operation, so
you can use str aig ht-t hr ough c abl es f or a ll netw ork conn ecti ons to PCs or ser ver s, or
to other switches or hubs. In straight-through cable, pins 1, 2, 3, and 6, at one end of
the cable, are connected straight thr ough to pins 1, 2, 3, and 6 at the oth er end of
the cable. When usi ng any RJ-45 port on t he switch, you can us e ei t her
straight-thro ugh or crossover cabl e.

1000BASE-T Pin Assignments

All 1000BASE-T ports support automatic MDI/MDI-X op er ation, so you can use
straight-through cables for all netwo rk connections to PCs or se rv er s, or to ot her
switches or hub s.

The table below shows the 1000BASE-T MDI and MDI-X port pinou ts. These ports
require that all four pairs of wires be connected. Note that for 1000BASE-T
operation, all four pair s of w ires are used for both tr an smit and receive.

Use 100-ohm Cat egory 5, 5e or 6 unshiel ded 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 ex ceed 100 meters (3 28 fee t).

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/ E IA - TSB-95 Bulletin, “The Add itional
Transmission Performance Guidelines for 100 Ohm 4-Pair Category 5 Cabling.”

Note that when test i ng your cable installatio n, be sure to include all patch cables
between switches and end devices.

Adjusting Existing Category 5 Cabling to Run 1000BASE-T

If your existing Ca te gor y 5 installation does no t meet one of the test parame te rs fo r
1000BASE-T, there are ba sically thr ee m easures that can be applied to try an d
correct the probl em :

1. Replace any Category 5 patch c ables with high-perf or m ance Category 5e or
Category 6 cables.

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

3. Reconn ect some of the connectors in the link.

Fiber Standards

The current TIA (Telecommunications Industry Association) 568-A specification on
optical fiber cabling consists of one recognized cable type for horizontal subsystems
and two cable types for backbone subsystems.

Horizontal 62.5/125 micron mu lti m ode (two fibers per ou tle t) .
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 th e types listed above. All opt ical fibe r
components and ins talla tion p ra cti ces must meet appl ic ab le bui l ding and safety
codes.
