Introduction
This hardware installation guide is for the following NETGEAR Smart Managed Pro Switches:
•24-Port Gigabit PoE+ Smart Managed Pro Switch with 4 SFP Ports, Model GS728TPv2
•24-Port Gigabit PoE+ Smart Managed Pro Switch with 4 SFP Ports, Model GS728TPPv2
•48-Port Gigabit PoE+ Smart Managed Pro Switch with 4 SFP Ports, Model GS752TPv2
•48-Port Gigabit PoE+ Smart Managed Pro Switch with 4 SFP Ports, Model GS752TPP
The switch provides twenty-four or forty-eight Gigabit RJ-45 copper PoE+ ports with four dedicated SFP ports.
Power over Ethernet plus (PoE+) lets you provide power to PoE-capable devices such as WiFi access points,
VoIP phones, and IP security cameras so that you do not need to use power supplies for those devices.The
maximum PoE+ (IEEE 802.3at) power that the switch can provide across all active PoE+ ports depends on the
model: 190W for model GS728TPv2, 380W for models GS728TPPv2 and GS752TPv2, and 760W for model
GS752TPP.
This hardware installation guide complements the installation guide that came with your switch.The resource
CD that came with your switch includes software and additional documentation and support resources.
This chapter serves as an introduction to the switch and includes the following sections:

Overview
The switch provides twenty-four or forty-eight 10/100/1000BASE-T RJ-45 copper ports that support nonstop
10/100/1000MLayer2 and Layer3 networks.All RJ-45ports support PoE+.Four additionalports can accept
small form-factor pluggable (SFP) gigabit interface converters (GBICs) for 1G fiber or copper connectivity.
For information about application samples, see Applications on page 15.Note
The switch provides administrative management options that let you configure, monitor, and control the
network. Using the local browser–based management interface, you can configure the switch and the
network, including theports,the managementVLAN,VLANs fortrafficcontrol, link aggregationforincreased
bandwidth, Quality of Service (QoS) for prioritizing traffic, and network security.
Initial discovery of the switch on the network requires the Smart Control Center program, which runs on a
Windows-based computer and is included on the resource CD.If you do not use aWindows-based computer,
get the IP address of the switch from the DHCP server in the network or use an IP scanner utility.
After discovery, you can configure the switch using the local browser interface for advanced setup and
configuration of features, or the Smart Control Center program for very basic setup. For more information,
see the user manual, which you can download from downloadcenter.netgear.com.
You can install the switch freestanding or rack mounted in a wiring closet or equipment room.The switch
is IEEE compliant and offers low latency. All ports can automatically negotiate to the highest speed, which
makes the switch very suitable for a mixed environment with Fast Ethernet and Gigabit Ethernet.
Use Category 5e (Cat 5e) or higher-rated Ethernet cables terminated with RJ-45 connectors to make Gigabit
connections.

GS752TPv2), or 760W (model GS752TPP)
•MAC table size of 16K.
•Variable speed fan that can lower the noise level during low temperatures.
•Acoustic noise (measured at 25°C) is equal to or less than 31 dBA (model GS728TPv2), 35 dBA (model
GS728TPPv2), 38 dBA (model GS752TPv2), or 43 dBA (model GS752TPP).
•56 Gbps (models GS728TPv2 and GS728TPPv2) or 104 Gbps (models GS752TPv2 and GS752TPP)
full-duplex, nonblocking switch fabric.

Safety Instructions andWarnings
Use the following safety guidelines to ensure your own personal safety and to help protect your system from
potential damage.
To reduce the risk of bodily injury, electrical shock, fire, and damage to the equipment, observe the following
precautions:
•This product is designed for indoor use only in a temperature-controlled (0–50°C) and humidity-controlled
(90 percent maximum relative humidity, noncondensing) environment.
Any device that is located outdoors and connected to this product must be properly grounded and surge
protected.
To the extent permissible by applicable law, failure to follow these guidelines can result in damage to
your NETGEAR product, which might not be covered by NETGEAR’s warranty.
•Observe and follow service markings:
-Do not service any product except as explained in your system documentation.
-Opening or removing covers that are marked with the triangular symbol with a lightning bolt can
expose you to electrical shock.We recommend that only a trained technician services components
inside these compartments.
•This device uses double-pole/neutral fusing.Servicing this device can present a risk of electrical shock.
Disconnect power before servicing the device.
•If any of the following conditions occur, unplug the product from the electrical outlet and replace the part
or contact your trained service provider:
-The power cable, extension cable, or plug is damaged.
-An object fell into the product.
-The product was exposed to water.
-The product was dropped or damaged.
-The product does not operate correctly when you follow the operating instructions.
•Keep your system away from radiators and heat sources. Also, do not block cooling vents.
•Do not spill food or liquids on your system components, and never operate the product in a wet
environment.If the system gets wet, see the appropriate section in your troubleshooting guide, or contact
your trained service provider.
•Do not push any objects into the openings of your system.Doing so can cause fire or electric shock by
shorting out interior components.
•Use the product only with approved equipment.
•Allow the product to cool before removing covers or touching internal components.
•Operate the product only from the type of external power source indicated on the electrical ratings label.
If you are not sure of the type of power source required, consult your service provider or local power
company.

•To avoid damaging your system, be sure that the voltage selection switch (if provided) on the power
supply is set to match the power at your location:
-115V, 60 Hz in most of North and South America and some Far Eastern countries such as South
Korea and Taiwan
-100V, 50 Hz in eastern Japan and 100V, 60 Hz in western Japan
-230V, 50 Hz in most of Europe, the Middle East, and the Far East
•Be sure that attached devices are electrically rated to operate with the power available in your location.
•Use only approved power cables. If you were not provided with a power cable for your system or for
any AC-powered option intended for your system, purchase a power cable approved for your country.
The power cable must be rated for the product and for the voltage and current marked on the product
electrical ratings label.The voltage and current rating of the cable must be greater than the ratings
marked on the product.
•To help prevent electric shock, plug the system and peripheral power cables into properly grounded
electrical outlets.
•The peripheral power cables are equipped with three-prong plugs to help ensure proper grounding. Do
not use adapter plugs or remove the grounding prong from a cable.If you must use an extension cable,
use a three-wire cable with properly grounded plugs.
•Observe extension cable and power strip ratings.Make sure that the total ampere rating of all products
plugged into the extension cable or power strip does not exceed 80 percent of the ampere ratings limit
for the extension cable or power strip.
•To help protect your system from sudden, transient increases and decreases in electrical power, use a
surge suppressor, line conditioner, or uninterruptible power supply (UPS).
•Position system cables and power cables carefully. Route cables so that they cannot be stepped on or
tripped over. Be sure that nothing rests on any cables.
•Do not modify power cables or plugs. Consult a licensed electrician or your power company for site
modifications.
•Always follow your local and national wiring rules.
