SMC

-EZ1016DT

The EZ Switch™ 10/100 (SMC-EZ1016DT) is a 16-port

Fast Ethernet switch. Its 16 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

u Auto-Negotiation of half or full-duplex on all ports

u ANSI/IEEE 802.3u compliance ensures compatibility

with standards-based hubs, switches and cards from

any vendor

u Store-and-forward switching ensures error-free

transmission

u Half- and full-duplex flow control prevents packets

from being dropped under heavy loading

u Plug and play

u Built-in wiring crossovers on all ports allow

connections to servers and workstations to be made

with straight-through cabling

u “At-a-glance” LEDs for port and system status

monitoring

u Desktop and rack mountable

Front Panel LEDs

The front panel of the switch provides a link status

LED for each RJ-45 port.  In addition, the front panel

also contains status LEDs for “at-a-glance” system

monitoring.  The following table details the functions

of the various indicators:

Front-Panel Ports

These ports are 10/100 Mbps RJ-45 ports with built-in

wiring crossovers.  PCs can be connected to these ports

with straight-through cable.  Each port supports Auto-

Negotiation, so the optimum communication mode

(half or full duplex) and data rate (10 Mbps or 100

Mbps) are selected automatically.

Port 16 has an associated toggle switch so that you can

change it from a crossover port to a straight-through

daisy-chain port.  Therefore, it is a simple matter to

connect straight-through cable from this port to a

crossover port on another device.

Rear Panel

The AC power receptacle is located on the rear panel

of the switch.

NSTALLING

THE

 S

WITCH

The EZ Switch 10/100 can be placed on a desktop or

shelf, or installed in a standard 19-inch equipment

rack.

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-EZ1016DT

• Appropriate AC power cable

• Rackmount kit

• SMC Warranty Registration Card

• This User Guide

Selecting a Site

Be sure to follow the site selection guidelines below

when choosing a location:

u

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.

u

Before rack mounting the switch, pay particular

attention to the following factors:

• Temperature:  Since the temperature within a

rack assembly may be higher than the ambient

room temperature, check that the rack-

environment temperature is within the specified

operating temperature range.

• Mechanical Loading:  Do not place any

equipment on top of a rack-mounted switch.

• Circuit Overloading:  Be sure that the supply

circuit to the rack assembly is not overloaded.

• Grounding:  Rack-mounted equipment should

be properly grounded.  Particular attention

should be given to supply connections other

than direct connections to the mains.

u

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.

u

Make sure that a properly grounded power outlet is

within 8 feet (2.44 meters) 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 feet to the

bottom of the switch.  For rack-mounting, attach the

mounting brackets on both sides of the switch with

the screws provided, and install the switch in the

rack.

2. 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.

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.

4. Connecting PCs:  Connect each PC to an RJ-45

port on the switch with a straight-through twisted-

pair cable segment, maximum 100 meters (328 feet).

The EZ Switch 10/100 will support up to 16 PCs.

However, before using port 16 to connect to a PC,

be sure to enable the crossover.  See the “Cable

Specifications” and “Connectivity Guidelines”

sections of this guide for further information.

Note: If an attached device does not support Auto-

Negotiation, the data rate will be sensed

automatically and communication mode will default

to half duplex.

5. Cascading Switches and Other Network Devices:

If you need more ports, set the daisy-chain toggle

switch to “=” (straight-through) and connect from

port 16 to a crossover port on another device. Be

sure to use straight-through twisted-pair cable,

maximum 100 meters (328 feet).

Note: Alternatively, you can cascade from any

crossover port on the switch to a daisy-chain port

on another device.  You may also connect to

crossover ports at both ends if you use a crossover

cable. See the “Cable Specifications” and

“Connectivity Guidelines” sections of this guide for

further information.

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

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 Mps

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.
