Preface

Congratulations on your purchase of the Dimension GS-1008/GS-1016 Gigabit Ethernet
Switch.

This preface introduces you to the Dimension GS-1008/GS-1016 Gigabit Ethernet
Switch and discusses the organization and conventions of this User’s Guide. It also
provides information on other related documentation.

About Gigabit Ethernet

Gigabit Ethernet is a 1Gbps (1000Mbps) extension of the IEEE 802.3 Ethernet
networking standard. Its primary applications are in corporate LANs, campus networks
and service provider networks where it can be used to tie together existing 100Mbps
Ethernet networks.

About the Dimension GS-1008/GS-1016 Gigabit Ethernet Switch

The GS-1008/GS-1016 is designed to improve your network performance with high­speed data transmission over copper wire. As an alternative to ATM, the GS-1008/GS­1016 provides an ideal upgrade path for existing Ethernet-based networks that need
more bandwidth. It can be installed as a backbone network while retaining existing
investments in Ethernet hubs, switches and wiring infrastructure.

General Syntax Conventions

For brevity’s sake, we will use “e.g.” as shorthand for “for instance”, and “i.e.” as
shorthand for “that is” or “in other words” throughout this manual.

The Dimension GS-1008/GS-1016 Gigabit Ethernet Switch may be referred to as the
switch in this manual.

bandwidth backbone. With the eight auto-negotiating 100/1000Base-T gigabit Ethernet

ports on the GS-1008 (16 on the GS-1016), you can connect the GS-1008/GS-1016 to

existing Ethernet routers, switches or hubs without additional expensive wiring or

equipment installation.

1.3 Backbone Switch Network Application

This section provides a sample of network topology in which the switch is used as a

high-bandwidth backbone. The switch is an ideal upgrade for 100Mbps Ethernet

networks. You can connect existing switches, hubs or computers with Gigabit

1000Base-T Ethernet adapters to the switch.

The following figure depicts a typical backbone application of the switch in an

enterprise environment. Workgroup A, Workgroup B, the standalone workstation with

gigabit Ethernet adapter and the two servers can all communicate with each other at

speed reaching 1000Mbps.

Hardware Description and

Installation

This section shows two switch installations, describes the switch hardware and

gives a functional overview of the switch.

The switch is suited to an office environment where it can be rack mounted on

standard EIA racks or as a standalone.

For proper ventilation, allow at least 4 inches (10 cm) of

clearance at the front, 3.4 inches (8 cm) at the back of the

switch. This is especially important for enclosed rack

installations.

2.1 Desktop Installation

Step 1. Set the switch upside-down on a study level space with a power outlet

nearby.

Step 2. Make sure there is enough clearance around the switch to allow air

circulation and the attachment of cables and the power cord.

Step 3. Remove the adhesive backing from the supplied rubber feet.

Step 4. Attach the rubber feet to each corner on the bottom of the switch. These

rubber feet help protect the switch from shock or vibration and ensure

space between devices when stacking.

Step 5. Turn the switch right-side up after you attach the rubber feet.

Hardware Description and Installation 2-1

Dimension GS-1008/GS-1016 Gigabit Ethernet Switch

Figure 2-1 Attaching Rubber Feet

Do not block the ventilation holes. Leave space between

switches when stacking.

2.2 Rack-mounted Installation

The switch can be mounted on an EIA standard size, 19-inch rack or in a wiring closet

with other equipment. Follow the steps below to mount your switch on a standard EIA

rack using the included rack-mounting kit.

Step 1. Align one bracket with the holes on one side of the switch and secure it

with the bracket screws. Similarly, attach the other bracket.

2-2 Hardware Description and Installation

Dimension GS-1008/GS-1016 Gigabit Ethernet Switch

Figure 2-2 Attaching Mounting Brackets and Screws

2. After attaching both mounting brackets, position the switch in the rack by lining

up the holes in the brackets with the appropriate holes on the rack. Secure the

switch to the rack with the rack’s mounting screws.

2.3 Rear Panel

The ventilation fan and three-pronged power receptacle are located on the rear panel

of the switch.

Figure 2-5 GS-1016 Rear Panel

2.3.1 Rear Panel Power Connection

Connect one end of the supplied power cord to the power receptacle on the back of the

switch and the other end to the 100-240V AC, 50-60Hz power source. For the GS-

1016, push the power switch to the ON position.

2.4.1 100/1000Mbps RJ-45 Auto-negotiating Ports

The GS-1016 has 16 1000Mbps RJ-45 ports. The GS-1008 has eight 100/1000Mbps

RJ-45 ports. The GS-1008’s auto-negotiation feature allows the switch to detect the

speed of incoming transmission and adjust appropriately without manual intervention.

It allows data transfers of either 100 Mbps or 1000Mbps in either half-duplex or full-

duplex mode depending on your Ethernet network.

2.4.2 Auto-sensing (Auto MDI/MDIX) Ports

You can connect each RJ-45 auto-sensing port to a computer, hub or switch using

either a straight-through or a crossover Ethernet cable.

2.4.3 Front Panel Connections

You can use unshielded twisted pair (UTP) or shielded twisted-pair (STP) Ethernet

cables for RJ-45 ports. The following table describes the types of network cable used

for the different connection speeds.

Table 2-1 Network Cable Types

SPEED NETWORK CABLE TYPE

100Mbps 100Ω 2-pair UTP/STP Category 5

1000Mbps 100Ω 4-pair UTP/STP Category 5

Troubleshooting

This section describes common problems you may encounter with the switch in

your network and possible solutions.

3.1 Introduction

Troubleshoot the switch using the LEDs to detect problems.

3.1.1 PWR LED

The PWR LED on the front panel does not light up.

Table 3-1 Troubleshooting PWR LED

STEPS CORRECTIVE ACTION

1 Check the connections from your switch to the power source. Make sure you

are using the supplied power cord and that you are using a 100 - 240V AC,
50/60Hz power source.

2 Make sure the power source is turned on and that the switch is receiving

sufficient power.

3 If these steps fail to correct the problem, contact your local distributor for

assistance.

3.1.2 LK/ACT or LNK/ACT LED

The LK/ACT (or LNK/ACT) LED does not light up when a device is connected.

Table 3-2 Troubleshooting LK/ACT LED

STEPS CORRECTIVE ACTION

1 Verify that the attached device(s) is turned on and properly connected to your

switch.

Troubleshooting 3-1

Dimension GS-1008/GS-1016 Gigabit Ethernet Switch

Table 3-2 Troubleshooting LK/ACT LED

STEPS CORRECTIVE ACTION

2 Make sure the Ethernet adapters are working on the attached devices.

3 Verify that proper network cable type is used and its length does not exceed 100

meters. For more information on network cable types, see 2.4.3 Front Panel
Connections.

3.1.3 100, 1000 LEDs

The LEDs do not show the speed of my Ethernet device.

Table 3-3 Troubleshooting 100, 1000 LEDs

STEPS CORRECTIVE ACTION

1 Check the connection between the switch and your Ethernet device(s).

2 Verify that you are using the proper cable type and that its length does not

exceed 100 meters. For more information on network cable types, see 2.4.3
Front Panel Connections.

3.1.4 FD or FDX/COL LED

What is the duplex mode of the Ethernet device?

Table 3-4 Troubleshooting FD LED

STEPS CORRECTIVE ACTION

The Ethernet device is connected at full-duplex mode if the FD LED is orange

the LK/ACT LED is on or blinking.

3.2 Improper Network Cabling and Topology

Improper network cabling or topology setup is a common cause of poor network

performance and network failure.

The network cables should not be longer than the limit of 100
meters.

Too many hubs (or repeaters) between the connected computers in
the network may increase the number of packet collisions or other
network problems. Remove unnecessary hubs from the network.

A data path loop forms when there is more than one path or route
between two networked computers. This results in broadcast storms
that will severely affect your network performance. Make sure there
are no loops in your network topology.
