warranty covers a product during the Life of that Product, which is defined as the period of
time during which the product is an “Active” SMC product. A product is considered to be
“Active” while it is listed on the current SMC price list. As new technologies emerge, older
technologies become obsolete and SMC will, at its discretion, replace an older product in its
product line with one that incorporates these newer technologies. At that point, the obsolete
product is discontinued and is no longer an “Active” SMC product. A list of discontinued
products with their respective dates of discontinuance can be found at:

Front Panel RJ-45 Ports
The EZ Switch 10/100/1000 features 16 1000BASE-T ports with RJ-45
connectors located on the front panel of the switch. Because all ports
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.
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 System Status LEDs
LED Condition Status

I NSTALLING THE S WITCH
Before installing the switch, verify that you have all the items listed under
“Package Contents.” Note that the switch can be installed on any suitably
large flat surface or in a standard EIA 19-inch rack.
Package Contents
The EZ Switch 10/100/1000 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.
• EZ Switch 10/100/1000 (SMC8516T)
• Four rubber foot pads
• Rack-mount bracket kit
• Appropriate AC power cord
•ThisUserGuide
• SMC Warranty Registration Card

• 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 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. For rack mounting,
install into a standard EIA 19-inch rack using the included brackets.
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 Category 5 or 5e shielded or unshielded twisted-pair (UTP or
STP) cable, maximum length 100 meters (328 ft). The EZ Switch 10/
100/1000 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.

I NSTALLING THE S WITCH

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
Specifications” on page 9 of this guide for further information.
Caution: Do not plug a phone jack connector into any RJ-45 port. This
may damage the switch. Instead, use only twisted-pair cables
with RJ-45 connectors that conform with FCC standards.

T ROUBLESHOOTING
Diagnosing Switch Indicators
1. Symptom
Power LED does not light after power on.
Probable Causes
• AC power cord may be defective.
Possible Solutions
• Check for loose connections.
• Check the power outlet by using it for another device.
• Replace the AC power cord.
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 or better cable is used for 10/100 Mbps
connections, Category 5 or 5e cable for 1000 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.
