1. Introduction
Congratulations on the purchase of your NETGEAR®ProSAFETM GS516TP Gigabit Smart
Switch. Your GS516TP Gigabit Smart Switch is a state-of-the-art, high-performance,
IEEE-compliant network solution designed for users who require many ports and want the power
of gigabit connectivity to eliminate bottlenecks, boost performance, and increase productivity.
The front panel of the switch has 16 twisted-paired ports that support nonstop 10/100/1000
networks. To simplify installation, the switch is shipped ready for use out of the box.
The installation guide describes how to install and power on the GS516TP Gigabit Smart Switch.
The information in this manual is intended for readers with intermediate computer and Internet
skills.
This chapter serves as an introduction to the GS516TP Gigabit Smart Switch and provides the
following information:

GS516TP Gigabit Smart Switch
Overview
The NETGEAR GS516TP Gigabit Smart Switch provides 16 twisted-pair ports that support
nonstop 10/100/1000M 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 10/100/1000M copper connectivity
The 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
•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
computer.
The switch can be freestanding or rack mounted in a wiring closet or equipment room. 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 this switch:
•Sixteen 10/100/1000 Mbps AutoSensing Gigabit Ethernet switching ports.
•The first eight ports are PoE (Power over Ethernet) PSE ports providing up to 15.4W of
DC power.
•Ports 15 and 16 are PD ports receiving power from power devices.
•Full NETGEAR Smart Switch functionality.
•Full compatibility with IEEE standards:
-IEEE 802.3i (10BASE-T)
-IEEE 802.3u (100BASE-TX)
-IEEE 802.3ab (1000BASE-T)

System LEDs
The following table describes the system LED designations.
Device Hardware Interfaces
The following sections describe the ports and buttons found on the smart switch.
RJ-45 Ports
RJ-45 ports are AutoSensing ports. When you insert a cable into an RJ-45 port, the switch
automatically ascertains the maximum speed (10, 100, or 1000 Mbps) and duplex mode
(half-duplex or full-duplex) of the attached device. All ports support only an unshielded
twisted-pair (UTP) cable terminated with an 8-pin RJ-45 plug.
To simplify the procedure for attaching devices, all RJ-45 ports support Auto Uplink. This
technology allows attaching devices to the RJ-45 ports with either straight-through or
crossover cables. When you insert a cable into the switch’s RJ-45 port, the switch
automatically does the following:
•Senses whether the cable is a straight-through or crossover cable.
•Determines whether the link to the attached device requires a “normal” connection (such
as when you are connecting the port to a computer) or an “uplink” connection (such as
when you are connecting the port to a router, switch, or hub).
•Configures the RJ-45 port to enable communications with the attached device, without
requiring user intervention. In this way, the Auto Uplink technology compensates for
setting uplink connections, while eliminating concern about whether to use crossover or
straight-through cables when you are attaching devices.
Table 2-2. System LEDs
LED Designation

Max PoE LED • Solid yellow. Less than 7W of PoE power is available.
•Blinking yellow. The PoE Max LED was lit within the previous two minutes.
•Off. At least 7W of PoE power is available.
PD15 and PD16 • Off. No PSE device is connected to ports 15 or 16.
•Solid green. An 802.3at PSE device is connected to ports 15 or 16.
•Solid yellow. An 802.3af PSE device is connected to ports 15 or 16.

Physical Description

GS516TP Gigabit PoE Smart Switch
Reset Button
The smart switch has a Reset button on the front panel to allow you to manually reboot the
switch. This action is equivalent to powering the unit off and back on. The last saved
configuration is loaded into the switch as it resets. To operate the Reset button, insert a
device such as a paper clip into the opening to press the recessed button. The front panel
LEDs turn off and light again as the switch performs its power-on self-test (POST).
Factory Defaults Button
The smart switch has a Factory Defaults button on the front panel so that you can remove the
current configuration and return the device to its factory settings. When you press the Factory
Defaults button, all settings including the password, VLAN settings, and port configurations
are removed. To operate the Factory Defaults button, insert a device such as a paper clip
into the opening to press the recessed button for over two seconds.

Installation
19
GS516TP Gigabit Smart Switch
Prepare the Site
Before you install the switch, ensure that the operating environment meets the site requirements
in the following table.
Install the Switch
The smart switch can be used on a flat surface or mounted in a standard network equipment
rack.
Install the Switch on a Flat Surface
The switch ships with four self-adhesive rubber footpads. Stick one rubber footpad on each
of the four concave spaces on the bottom of the switch. The rubber footpads cushion the
switch against shock and vibrations.
Install the Switch in a Rack
You need the rack-mount kit supplied with the switch to install the switch in a rack.
To install the switch in a rack:
1. Attach the supplied mounting brackets to the side of the switch.
Table 4-3. Site Requirements
Characteristics Requirements
Mounting • Desktop installations. Provide a flat table or shelf surface.
•Rack-mount installations. Use an EIA standard equipment rack that is grounded and
physically secure. The rack-mount kit supplied with the switch is also required.
Access Locate the switch in a position that allows you to access the front panel RJ-45 ports, view the
front panel LEDs, and access the power connector.
Power source Provide a power connection cord. For information about power specifications for the switch, see
Appendix A, Troubleshooting. Ensure that the AC outlet is not controlled by a wall switch, which
can accidentally turn off power to the outlet and the switch.
Environmental • Temperature. Install the switch in a dry area, with ambient temperature between 0ºC and
40ºC (32ºF and 104ºF). Keep the switch away from heat sources such as direct sunlight,
warm-air exhausts, hot-air vents, and heaters.
•Operating humidity. The installation location should have a maximum relative humidity of
90%, non condensing.
•Ventilation. Do not restrict airflow by covering or obstructing air inlets on the sides of the
switch. Keep at least 2 inches (5.08 centimeters) free on all sides for cooling. Be sure that
there is adequate airflow in the room or wiring closet where the switch is installed.
•Operating conditions. Keep the switch at least 6 feet (1.83 meters) away from nearest
source of electromagnetic noise, such as a photocopy machine.

Installation

2. Insert the screws provided in the rack-mount kit through each bracket and into the bracket
mounting holes in the switch.
3. Tighten the screws with a No. 1 Phillips screwdriver to secure each bracket.
4. Align the mounting holes in the brackets with the holes in the rack, and insert two pan-head
screws with nylon washers through each bracket and into the rack.
5. Tighten the screws with a No. 2 Phillips screwdriver to secure mounting brackets to the rack.
Check the Installation
Complete this task before applying power to the switch.
To check the installation:
1. Inspect the equipment thoroughly.
2. Verify that all cables are installed correctly.
3. Check cable routing to make sure that cables are not damaged or creating a safety hazard.
4. Ensure that all equipment is mounted properly and securely.
