CHAPTER 1: INTRODUCTION

The NETGEAR Model GS516T 16-Port Copper Gigabit Switch provides you with a low-cost, high-performance network solution and is designed to anchor and interconnect 10/100/1000 megabits per second (Mbps) workgroups using copper Gigabit links.

Features

The Model GS516T switch has the following key features:

• 16 full-duplex copper Gigabit ports with standard RJ-45 connectors

• Automatic address learning function to build the packet-forwarding

information table. The table contains up to 8,000 media access control (MAC) addresses (that is, the switch can support networks with as many as 8,000 devices).

• Address aging function to automatically track changes in network configuration

• Protocol independence and compatibility with all common protocols, such as

TCP/IP, Netware, DECNet, Microsoft Networks, and AppleTalk

• Full-duplex mode to double throughput of point-to-point connections by letting indi-

vidual ports transmit and receive concurrently when the other end also supports full-duplex mode

• Wire-speed filtering and forwarding of the traffic

• Store-and-forward intelligent processing to minimize erroneous packets on the net-

work

• Easy Plug and Play installation with no software to configure, which saves time and

minimizes the potential for configuration errors

• Auto Uplink

in all ports to make the right connection

• Auto-negotiation with link partners to speeds of 10, 1000, or 1000Mbps on all

ports

• Flow control traffic management to ensure no packets are dropped if there are

back-ups or bottlenecks in the network
