ABOUT THE EZ SWITCH 10/100

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 Auto­Negotiation, 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.

INSTALLING THE SWITCH

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 rack­environment 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 twisted­pair 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 Auto­Negotiation, 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.

defective.

Possible Solutions

• Check that the switch and attached device are
both powered on.

• Be sure the network cable is connected to both

• 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.

RJ-45 Connector 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.

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 specific orientation. Note how the pins are
numbered in the illustration below. Be sure to hold
the connectors in the same orientation when attaching
the wires to the pins.

Note: The “+” and “-” signs are used to represent the
polarity of the wires that make up each wire pair.
