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 high-
speed data transmission over copper wire. As an alternative to ATM, the GS-1008/GS-
1016 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.

Chapter 1
Getting to Know the GS-1008/
GS-1016
This chapter describes the key features, benefits and applications of the GS-
1008/GS-1016.
The GS-1008/GS-1016 is designed for the campus or building environment as a high
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 2-1
Chapter 2
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.

2-2 Hardware Description and Installation
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. 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.
