I NTRODUCTION
The EZ Switch™ 10/100, SMC-EZ6516TX, is a 16-port Fast Ethernet
switch. The 10BASE-T/100BASE-TX ports deliver dedicated
10/100 Mbps links to each attached LAN segment—all with conventional
cabling and adapters. Auto-negotiation 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 is
always maintained even under heavy loading. Easy installation and
reliability make this plug-and- play switch an ideal choice for smooth Fast
Ethernet integration.
Features and Benefits
• Auto-negotiation of half or full duplex on all ports
• Automatic MDI/MDI-X operation
• IEEE 802.3u and 802.3 compliance ensures compatibility with
standards-based hubs, switches and cards from any vendor
• Store-and-forward switching ensures error-free transmission
• Half- and full-duplex flow control prevents packets from being
dropped under heavy loading
• Plug-and-play
• “At-a-glance” LEDs for port and system status monitoring
• Desktop installation

LED Indicators
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.
Rear Panel
This EZ Switch 10/100 model features 16 10BASE-T/100BASE-TX
ports with RJ-45 connectors located on the rear panel of the switch.
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.
The DC power receptacle is located on the rear panel of the switch.

The EZ Switch 10/100 can be placed on a desktop or shelf, and stacked
with other switches using the provided 4 rubber foot pads.
Package Contents
The EZ Switch 10/100 includes:
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.
• There should be adequate space (approximately two inches) on all
sides for proper air flow.
• EZ Switch 10/100 (SMC-EZ6516TX)
• Four rubber foot pads
•ThisUserGuide
• Appropriate DC power adapter
• SMC Warranty Registration Card

• 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 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
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 length
100 meters (328 ft). The EZ Switch 10/100 will support up to 16 PCs.
All ports on the switch 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.
Note: If an attached device does not support auto-negotiation, the data
rate will be sensed automatically and the communication mode
will default to half duplex.
4. Cascading Switches and Other Network Devices: All the ports on
the switch support automatic MDI/MDI-X configuration for cable
connections. This allows you to use straight-through cable to connect
to other switches or hubs from any port on the switch. No crossover
cables or other device settings are needed. See the “Cable

T ROUBLESHOOTING
1. Symptom
Power LED does not light after power on.
Probable Causes
• DC power adapter may be defective.
Possible Solutions
• Check for loose connections.
• Check the power outlet by using it for another device.
• Replace the DC power adapter.
2. Symptom
Link LED does not light after connection is made.
Probable Causes
• Switch 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).

Cable Specifications
Twisted-Pair Cable and Pin Assignments
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.
For 10BASE-T/100BASE-TX connections, a twisted-pair cable must have
two pairs of wires. Each wire pair is identified by two different colors. For
example, one wire might be red and the other, red with white stripes. Also,
an RJ-45 connector must be attached to both ends of the cable.
Caution: Each wire pair must be attached to the RJ-45 connectors in a
specific orientation.
The figure below illustrates how the pins on the RJ-45 connector are
numbered. Be sure to hold the connectors in the same orientation when
attaching the wires to the pins.
