The EZ Switch 10/100 SMC-EZ10 9DT is an 8-port Fast Ethernet
switch with one Gigabit uplink port. The 10BASE-T/100BASE-TX
ports deliver dedicated 10/100 Mbps links to each attached LAN
segment. The Gi ga bit port opera tes at 100 and 1000 Mbps. Each
port on the switch supports automatic MDI/MDI-X detection. This
means that you can u s e eith er st ra ight -thr ough or cr oss over cab les
to connect to any other network device.

Auto-negotia tion 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 i s a lw ays mainta ined, even under heavy loading. Easy
installation and reliability make this plug-and-play switch an ideal
choice for smoot h Fast Ethernet integration.

Equipment Checklist

After unpacking the EZ Sw itch 10/100, check th e contents of the
box to be sure you h a ve received the following components:

• EZ Switch 10/100 SMC-EZ109DT

• Appropriate AC power cable

• Four adhesive foot pads & rackmount kit

• SMC Warranty Registration C a rd

•This User Guide

Selecting a Site

Be sure to follow the site selection guidelines below when
choosing a location:

WITCH

 Select a suitable location for the switch:

• It should be access ible for installing, cabling and
maintaining th e switch.

• The temperatur e and humidity should be withi n the ranges
listed in the sp ecifications .

• The status LEDs should be clearly visible.

• There should be adequate space (approximately two
inches) on all sides for proper air flow.

 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.

5

I

NSTALLING THE SWITCH



Make sure that a properly grounded power outlet is within 2.44
meters (8 feet) of the switch and is powered from an
independent circuit breaker. As with any equipment, using a
filter or surge suppressor is recommended.

Instructions

Positioning the Switch

The EZ Switch 10/100 can be placed anywhere there is enough flat
space, such as on a desktop or a shelf.

1. Attach the four adhesi ve feet to the bottom of the switch.

2. Place the first switch on a firm, flat surface where you want to

install the stack

3. Repeat step 1 for each switch before stacking them. The rubber
foot pads cushion the switch against shocks and vibrations,
and provide space between each switch for ventilation.

Applying Power

Plug one end of the power cable into the power receptacle at the
back of the switch, and the other end into an appropriate electrical
outlet. Check the Power LED to be sure power is on.

I

NSTALLING THE SWITCH

Note: It is not necessary to po w e r off the switch before

connecting or disconnecting any UTP cables, as these
actions will not disrupt the operation of other devices
attached to the switch.

RJ-45 10/100 Mbps Connections

For twisted-pair devices, connect each PC to an RJ-45 port on the
switch with a twisted-pair cable segment, maxi mum 100 meters
(328 feet). Use Category 3, 4, or 5 cable for 10 Mbps conn ec tions,
and Category 5 cable for all 100 Mbps connections.

Note: If an attached de vice does not support

auto-negotiation, the data rate will be sensed
automatically and the com munication mode will
default to half duplex.

Connecting to the Gigabit Uplink Port

The Gigabit uplink port operates at 1000 and 100 Mbps and
supports IEEE 802.3x flow control. Auto-negotiation is used to
select the opti m a l transmission spe ed and communication mode.
Use Category 5 or 5e cable of maximum length 100m (328 feet).
You should also test the cable installation for IEEE 802.3ab
compliance. See “1000BASE-T Cable Requirements” on page 14.

NSTALLING THE SWITCH

Sample Applications

This switch segments your network, significantly increasing both
bandwidth and throughput. Any port on the switch can be
attached to a hub ( a shared collision domain) or pr ovide a
dedicated link t o a single n etwork device (such as a workstatio n or
server). When a port on the switch is connected to a hub (a 10 or
100 Mbps repeater), the bandwidt h provided by that port is shared
by all the devices c on nected to the attache d hub. However, when
a port is connected to an end nod e or to a devic e that breaks up
the collision domain (e.g., another switch, bridge or router), the
attached device has access to the fu l l bandwidth provided by that
port.

Bridging Functions - This switch provides fully t ransparent
bridging functi ons. I t au tom atical ly l earns nod e ad dresses , th at are
subsequently used to filt er and fo rwar d all tr affic based on the
destination address. When traffic passes between devices attached
to the same shared collision domain, those packets are filtered
from the switch. But when traffic must be pas s ed between unique
segments (i.e., different ports on the switch), the high-speed
switching fabric forwards the packets at near zero latency.

Switching Functions - Store-and-forward switching is us ed to
forward traffic to other ports. This scheme ensures data integrity
and provides a clean data stream.

Flexible Configuration - This switch is not only designed to
segment your netwo rk, but also to provi de a wide range of options
in setting up network connections. It can be used as a simple
stand-alone switch; or be connected with standard repeater hubs,
switches, or other network interconnection devices in vari ou s
configurations.

NSTALLING THE SWITCH

Gigabit Uplink Port - You can use the Gigabit port to support
applications such as hig h-sp eed file serv er s, or fo r conn ecti ng to a
collapsed backbone switch.

In the figure below, the EZ Switch 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. The Gigabit
port is used to provide a 2 Gbps full-duplex link to a server.

Possible Solutions

• Check that the switch and attached device are both
powered on.

• Be sure the network cab l e is conn ected to both devices.

• Verify that Category 5 cable is used for 100 Mbps

connections and that the len gt h of any cab l e doe s not
exceed 100 meters (328 feet).

• Check the network car d and cable conne ctions for defe cts.

• Replace the defect i ve card or cable if ne cessary.

10BASE-T/100BASE-TX Pin Assignments

An Ethernet or Fast Ethernet twisted-pair link segment requires
two pairs of wires. Each wire pair is identified by two different
colors. Each wire pair must be attached to the RJ-45 connector in a
specific orientation detailed below.

Because all ports on this 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. In
straight-through cable, pins 1, 2, 3, and 6, at one end of the cable,
are connected straight through to pins 1, 2, 3 and 6 at the other

end of the cable.

1000BASE-T Cable Requirements

All Category 5 UTP cables that are used for 100B A S E-T X
connections shou ld also work for 1000BASE-T, providing that all
four wire pairs a r e connected. Ho w ever, it is recommended tha t
for all critical c onnections , or any new c able install ations, 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 pre p a ring existing Category 5 cabling
for running 1000BASE -T is a simple te st of th e cabl e installat io n to
be sure that it complies with the IEEE 802.3ab standards.

Cable Testing for Existing Category 5 Cable

Installed Category 5 cabling mus t pa ss tests for Attenuatio n,
Near-End Crosstalk (NEXT), and Far- End Crosstalk (FE XT). This
cable testing information is specified in the ANSI/TIA/EIA-TSB-67
standard. Additionally, cables must also pass test parame te rs 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 Perfo rmance Gui de lines for 100 O hm
4-Pair Category 5 Cabling.”

Note that when testing your cable installation, be sure to include
all patch cables between switches and end devices.

14

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 hig h- pe rformance
Category 5e cables.

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

3. Reconnect some of the connectors in the link.
