This manual describes how to install and use SMC’s EZ
Switch 10/100. It features 5,8 10/100 Mpbs Auto
Negotiation swtich ports, and provides the flexibility to fit
into your working space with network environment. The
EZ Switch 10/100 can be used to connect with PCs,
servers, hubs, bridges, other switches and routers. It can
also act as a bridge between 10Mbps and 100Mbps
networks segments.
This EZ Switch supports 10Mbps and 100Mbps dedicated
bandwidths in each port. The Switch is built with plug &
play, auto-negotiation on all ports, store-and-forward
transmission scheme, IEEE802.3x flow control and back
pressure operation for easy installation and smooth
transition from legacy 10Mbps to 100Mbps Ethernet
networks. All ports support MDI/MDI-X to facilitate your
network expansion.
Description of Hardware
The EZ Switch™ 10/100, SMC-EZ6505TX, and
SMC-EZ6508TX , are 5/8-port Fast Ethernet switch
featuring 5/8 10BASE-T/100BASE-TX auto-negotiation
ports. These switches provide an ideal bridge between 10
Mbps and 100 Mbps Ethernet networks.
Features and Benefits
• IEEE 802.3 and 802.3u compliance ensures
compatibility with standards-based hubs, switches and
cards from any vendor
• 5/8 dual-speed 10/100 Mbps auto-negotiation ports
• Plug and play—nothing to configure
• Built-in wiring crossovers on all ports allow

disruption
• Automatic polarity detection and correction
• Desktop installation
Front Panel LEDs
The front panel of the switch provides status LEDs for
“at-a-glance” system monitoring. The following table
details the functions of the various indicators:
Port and Switch Status LEDs

Rear Panel
These EZ Switch 10/100 models feature 5/8 10BASE-T/
100BASE-TX ports with RJ-45 connectors located on the
rear panel of the Switch. Each port contains a built-in
wiring crossover (MDI-X) that allows for the use of
straight-through twisted-pair cable for connections to
devices without built-in crossover ports (i.e., workstations,
printers, etc.).
The DC power receptacle is also located on the rear panel
of the hub.

Equipment Checklist
After unpacking the EZ Switch 10/100, check the contents
of the box to be sure you’ve received the following
components:
• EZ Switch 10/100 SMC-EZ6505TX or
SMC-EZ6508TX
• Appropriate DC power adapter
• Four rubber foot pads
• SMC Warranty Registration Card
•ThisUserGuide
Selecting a Site
Be sure to follow the site selection guidelines below when
choosing a location:
• Select a suitable location for the switch:
• It should be accessible for installing, cabling and
maintaining the switch.
• The temperature and humidity should be within
the ranges listed in the specifications.
• The status LEDs should be clearly visible.

I NSTALLING THE S WITCH

• 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,
transmitters, etc.
• Make sure that a properly grounded power outlet is
within 8 feet (2.44 meters) of the hub and is powered
from an independent circuit breaker. As with any
equipment, using a filter or surge suppressor is
recommended.
Instructions
1. Positioning the Switch: For desktop or shelf mounting,
attach the four adhesive foot pads to the bottom of the
switch.
2. Applying Power: Plug one end of the power adapter into the
socket on the switch’s rear panel, and the other end into an
appropriate electrical outlet. Check the Power LED to be sure
power is on.
Note: It is not necessary to power 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.
3. Connecting PCs: Connect each PC to an RJ-45 port on the
switch using a straight-through twisted-pair cable segment,
maximum 100 meters (328 ft.). The EZ Switch 10/100 will
support up to 5/8 PCs.
4. Cascading Switch and Other Network Devices: Prepare
straight-through Category 5 twisted-pair cable with RJ-45
plugs. Make sure the cable does not exceed 100 meters (328
feet). Connect one end of the cable to the switch’s port, and
connect the other end of the calbe to an MDI/MDI-X RJ-45
port on the other device.

T ROUBLESHOOTING
1. Symptom
Power LED does not light after power on.
Probable Causes
Power outlet or power cord may be defective.
Possible Solutions
• Check for loose connections.
• Check the power outlet by using it for another
device.
• Replace the power cord.
2. Symptom
Link LED does not light after connection is made.
Probable Causes
Swith port, network card or cable may be defective.
Possible Solutions
• Check that the Switch and attached device are
both powered on.
• Be sure the network cable is connected to both
devices.
• Verify that Category 5 cable is used for 100 Mbps
connections and that the length of any cable does

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.
An Ethernet or Fast Ethernet twisted-pair link segment
requires two pairs of wires. Each wire pair is identified by
two different colors. For example, one wire might be green
and the other, green with a white stripe.
Each wire pair must be attached to the RJ-45 connector in a
