Introduction
Congratulations on the purchase of your GS108T Gigabit Smart Switch. The GS108T Smart
Switch is a state-of-the-art, high-performance, IEEE-compliant network solution designed for
users who require a small desktop switch and want the power of Gigabit connectivity to eliminate
bottlenecks, boost performance, and increase productivity. To simplify installation, the switch is
shipped ready for use out of the box.
This chapter serves as an introduction to the GS108T Smart Switch and provides the following
information:
•Overview
•Features
•Package Contents
Overview
This Installation Guide is for the GS108T Gigabit Smart Switch. This product offers support for
eight 10/100/1000 Mbps auto-sensing ports.
Using Gigabit ports, high-speed connections can be made to a server or network backbone. For
example:
• Linking to high-speed servers
• Providing 10/100/1000 Mbps copper connectivity
The GS108T Smart Switch also provides the benefit of administrative management with a
complete package of features for the observation, configuration, and control of the network. With a
Web-based Graphical User Interface (GUI), the switch’s many capabilities can be viewed and used
in a simple and intuitive manner. The switch’s management features include configuration for port
and switch information, VLAN for traffic control, port trunking for increased bandwidth, and
Class of Service (CoS) for traffic prioritization. These features provide better understanding and
control of the network. Initial discovery of the switch on the network requires the Smart Control
Center program, a utility that runs on a PC.

GS108T Hardware Installation Guide
1-2 Introduction
v1.0, January 2010
The GS108T Smart Switch is a free-standing switch. It is IEEE-compliant and offers low latency
for high-speed networking. All ports can automatically negotiate to the highest speed. This
capability makes the switch ideal for environments that have a mix of Ethernet, Fast Ethernet, or
Gigabit Ethernet devices. In addition, all RJ-45 ports operate in half-duplex or full-duplex mode.
The maximum segment length is 328 feet (100 meters) over Category 5 Unshielded Twisted-Pair
(UTP) cable.
Features
The following list identifies the key features of the GS108T Smart Switch.
• Eight RJ-45 10/100/1000 Mbps auto sensing Gigabit switching ports.
• The devices support full NETGEAR Smart Switch functionality.
• The devices provide full compatibility with IEEE standards:
• IEEE 802.3i, (10BASE-T)
• IEEE 802.3u (100BASE-TX)
• IEEE 802.3ab (1000BASE-T)
• IEEE 802.3x (Full-duplex flow control)
• IEEE 802.3af (Power over Ethernet)
• Auto-sensing and auto-negotiating capabilities for all ports.
• Auto Uplink™ on all ports to make the right connection.
• Automatic address learning function to build the packet-forwarding information table. The
table contains up to 4K Media Access Control (MAC) addresses.
• Store-and-Forward transmission to remove bad packets from the network.
• Full-duplex IEEE 802.3x pause frame flow control.
• Active flow control to minimize packet loss/frame drops.
• Half-duplex back-pressure control.
• Per port LEDs, power LED.
• NETGEAR Green product series.
• External 12V/1A PA or power obtained from IEEE 802.3af PSE.
