EZ Switch 10/100/1000

INTRODUCTION

The EZ Switch 10/100/1000, SMCGS5 and SMCGS8, are
high-performance Gigabit Ethernet switches designed for
delivering Gigabit connectivity to the desktop. It provides
5/8 full-duplex 1000BASE-T ports that significantly
improve network performance and boost throughput for
high-bandwidth applications. With 10/16 Gigabits of
aggregate bandwidth, this switch provides the quickest
solution to meeting the growing demands on your
network's limited resources.

Features and Benefits

• Auto-negotiation supported on all ports

• Automatic MDI/MDI-X operation

• IEEE 802.3ab, 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-nothing to configure

• "At-a-glance" LEDs for port and system status
monitoring

• Desktop installation

Front Panel RJ-45 Ports

The EZ Switch 10/100/1000 features 5/8 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.

INSTALLING

THE SWITCH

Before installing the switch, verify that you have all the
items listed under “Package Contents.” If any of the items
are missing or damaged, contact your local SMC distributor.
Also be sure you have all the necessary tools and cabling
before installing the switch.

Package Checklist

The EZ Switch 10/100/100 package includes:

• The EZ Switch 10/100/1000 (SMCGS5 or SMCGS8)

• Four rubber feet

• Appropriate DC power adapter

• SMC Warranty Registration Card

• This User Guide
Please register this product and upgrade the product

warranty at www.smc.com.

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.

• The status LEDs should be clearly visible.

4

EZ Switch 10/100/1000

• 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 m (6.6 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 Category 5 or 5e shielded or
unshielded twisted-pair (UTP or STP) cable, maximum
length 100 meters (328 ft). 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.

5

EZ Switch 10/100/1000

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.

ROUBLESHOOTING

Diagnosing Switch Indicators

1. Symptom

Power LED does not light after power on.

Probable Causes

• DC power socket may be defective.

Possible Solutions

• Check for loose connections.

• Check the power outlet by using it for another device.

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.
