Rear Panel
These EZ Switch 10/100 models feature 16 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:
• EZSwitch 10/100 SMC-EZ6516TX
• 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 5/8/16 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.

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
not exceed 100 meters (328 feet).
• Check the network card and cable connections
for defects.
• Replace the defective card or cable if necessary.

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.
