Overview
Your NETGEAR GS748T Gigabit Smart Switch provides 48 twisted-pair ports with four built-in
Small Form Factor (SFP) GBIC slots that support nonstop 10/100/1000M fiber networks. Using
these Gigabit slots, you can create high-speed connections to a server or network backbone. For
example, you can:
• Connect switches to each other with high-speed links
• Link to high-speed servers
• Provide 10/100/1000 copper and fiber connectivity
Your GS748T Gigabit Smart Switch also provides the benefit of administrative management with
a complete package of features for the observation, configuration, and control of your 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. There is also an easy to use switch management utility
that runs on a PC. The switch’s management features include configuration for port and switch
information, VLAN for t raf fic cont rol, port trunking for incr eased bandwi dth, and Cla ss of Ser vice
(CoS) for traffic prioritization. These features, and more, enable you better to understand and
control your network.
Your NETGEAR GS748T Gigabit Smart Switch ca n be free-standing or rack-mounted in a wirin g
closet or equipment room. It is IEEE-c ompliant an d off ers low lat ency for high- speed networ king.
It includes 48 auto-sensing 10/100/1000 Ethernet ports with 4 SFP GBIC slots. All ports can
automatically negotiate to the highest speed. This capability makes the switch idea l for
environments th at have a mix of Etherne t, Fast Eth ernet, and Gigabit Et hernet dev ices. In addit ion,
all 10/100/1000 Mbps ports operate in half- or full-duplex mode, increasing the maximum
bandwidth of each connection to either 20 Mbps, 200 Mbps, or 2000 Mbps, respectively. The
maximum segment length is 328 feet (100 meters) ove r Category 5 unshielded twi st ed- pai r (UTP)
cable.
