Introduction
This hardware installation guide is for the following NETGEAR Smart Switches with
optional Remote/Cloud Management via the NETGEAR Insight network management
cloud portal and app:
•GS728TPv3: 24-Port Gigabit Ethernet PoE+ Smart Switch with 4 SFP Ports (190W)
•GS728TPPv3: 24-Port Gigabit Ethernet PoE+ Smart Switch with 4 SFP Ports (380W)
•GS752TPv3: 48-Port Gigabit Ethernet PoE+ Smart Switch with 4 SFP Ports (380W)
•GS752TPPv3: 48-Port Gigabit Ethernet PoE+ Smart Switch with 4 SFP Ports (760W)
The switch provides twenty-four or forty-eight Gigabit RJ-45 copper PoE+ ports with
four dedicated SFP ports. Power over Ethernet plus (PoE+) provides power to
PoE-capable devices such as WiFi access points, VoIP phones, and IP security cameras
so that you don’t need to use power adapters 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 GS728TPv3, 380W for models GS728TPPv3 and GS752TPv3, and 760W
for model GS752TPPv3.
This hardware installation guide complements the installation guide that came with your
switch.
This chapter serves as an introduction to the switch and includes the following sections:
• Overview
• Management options
• Features
• Safety instructions and warnings
Note: For more information about the topics that are covered in this guide, visit the
support website at netgear.com/support/.
Note: For switch documentation, visit netgear.com/support/download/ and enter your
model number in the search box.

Overview
The switch provides twenty-four or forty-eight 10/100/1000BASE-T RJ-45 copper ports
that support nonstop 10/100/1000M Layer 2 and Layer 3 networks. All RJ-45 ports
support PoE+. Four additional ports can accept small form-factor pluggable (SFP) gigabit
interface converters (GBICs) for 1G fiber or copper connectivity.
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 well-suited 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.
You can use the switch for multiple network applications with PoE and PoE+ devices
and non-PoE devices. For more information, see Applications on page 20.
Management options
The switch provides management options that let you discover the switch on the network
and configure, monitor, and control the switch:
•Device user interface: By default, the management mode of the switch is set to
Directly Connect to Web Browser Interface, which lets you access the device user
interface (UI). In this mode, you can change all settings of the switch.
For more information about the device UI, see the user manual. To find the user
manual, visit netgear.com/support/download/ and enter your model number in the
search box.
Note: If you plan to use NETGEAR Insight to manage the switch, we recommend
that you do not use the device UI to change settings that are Insight manageable.
These settings would not be synchronized with Insight or to the network location to
which you assigned the switch. We recommend that use the Insight Cloud Portal or
Insight app to change Insight manageable settings.
•Smart CLI: The smart command-line interface (CLI) is a text-based way to manage
and monitor the switch. You can access the CLI by using a direct serial connection,
or by using a remote logical connection with telnet or SSH. For more information
Hardware Installation Guide6Introduction
24-Port and 48-Port Gigabit Ethernet PoE+ Smart Switches with 4 SFP Ports

about the smart CLI, see the CLI manual. To find the CLI manual, visit
netgear.com/support/download/ and enter your model number in the search box.
•NETGEAR Insight Cloud Portal and Insight app: If you set the management mode
of the switch to NETGEAR Insight Mobile App and Insight Cloud Portal, you can use
the following applications to manage the switch remotely:
-Insight Cloud Portal: As an Insight Premium or Insight Pro user, you can use the
Insight Cloud Portal to set up the switch in the network; perform remote setup;
configure, manage, and monitor the switch; analyze the switch and network
usage; and, if necessary, troubleshoot the switch and the network.
-Insight app: With the Insight app, you can discover the switch on the network
and add it to a network location. You can then set up the switch in the network,
and manage and monitor the switch remotely from your tablet or smartphone.
You can choose from four methods to add the switch to the Insight app: You can
scan your network for the switch, scan the QR code of the switch, scan the barcode
of the switch, or add the serial number of the switch.
For more information about NETGEAR Insight, visit netgear.com/insight. The Insight
Cloud Portal and Insight app have embedded help and are documented in multiple
knowledge base articles that you can access by visiting netgear.com/support.
By default, the management mode is set to Directly Connect to Web Browser Interface
(which is the same as the device UI). Note the following about changing the
management mode:
-Changing to NETGEAR Insight Mobile App and Insight Cloud Portal mode.
The first time that you change to this mode, the switch is set to factory default
settings so that you can manage the switch using the Insight Cloud Portal or
Insight app. However, if you previously added the switch to a network on Insight,
all Insight-manageable device settings revert to the configuration in the Insight
cloud, including the switch password (that is, the password is reset to the Insight
network password).
Note: If you use the Insight app or the Insight Cloud Portal, you can temporarily
change the management mode of the switch back to Directly Connect to Web
Browser Interface and access the device UI for settings that are not
Insight-manageable. You might want to do this for tasks such as integrating with
an existing network of devices that are not managed through Insight, and for
debugging purposes. When you are done, you can change the management
mode back to NETGEAR Insight Mobile App and Insight Cloud Portal.
-Changing back to Directly Connect to Web Browser Interface mode: The
NETGEAR Insight Mobile App and Insight Cloud Portal management mode is
disabled and the current Insight-manageable device settings are saved to the
Hardware Installation Guide7Introduction

Switch hardware interfaces
The following sections describe the hardware interfaces on the switch.
RJ-45 ports for 10/100/1000M BASE-T Ethernet connectivity
All RJ-45 copper ports support autosensing. When you insert a cable into an RJ-45 port,
the switch automatically detects the maximum speed (10 Mbps, 100 Mbps, or 1 Gbps)
and duplex mode (half-duplex or full-duplex) of the attached device. All ports support
a Category 5e (Cat 5e) cable (or higher-rated Ethernet cable) terminated with an 8-pin
RJ-45 connector.
Hardware Installation Guide17Hardware Overview
24-Port and 48-Port Gigabit Ethernet PoE+ Smart Switches with 4 SFP Ports

To simplify the procedure for attaching devices, all RJ-45 ports support Auto Uplink
technology. 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 performs
the following actions:
•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).
•Automatically configures the RJ-45 port to enable communications with the attached
device. The Auto Uplink technology compensates for setting uplink connections
while eliminating concern about whether to use crossover or straight-through cables
when you attach devices.
All copper ports also support Power over Ethernet (PoE+).
SFP ports for fiber or copper connectivity
To enable fiber or additional copper connections on the switch, SFP ports accommodate
standard small form-factor pluggable (SFP) gigabit interface converters (GBICs, also
referred to as transceiver modules) for 1G fiber or copper connectivity. GBICs are sold
separately from the switch.
The switch supports the following NETGEAR SFP transceiver modules:
•AGM731F SFP transceiver 1000BASE-SX, SFP short-reach multimode LC GBIC
•AGM732F SFP transceiver 1000BASE-LX, SFP long-reach multimode LC GBIC
•AGM734 SFP transceiver 1000BASE-T, SFP copper RJ-45 GBIC
For more information about NETGEAR SFP transceiver modules and cables, visit
netgear.com/business/products/switches/modules-accessories.
Single-function Reset button
The switch provides a single-function Reset button on the front panel so that you can
restart the switch. We recommend that you save the configuration before you press the
Reset button.
To restart the switch:
1. Insert a device such as a straightened paper clip into the opening.
2. Press the recessed Reset button for more than one second.
During the restart process, the Power LED lights yellow.
Hardware Installation Guide18Hardware Overview
24-Port and 48-Port Gigabit Ethernet PoE+ Smart Switches with 4 SFP Ports

Dual-function Factory Defaults button
The switch provides a dual-function Factory Defaults button on the front panel.
Depending on how long you press the button (for details, see the following procedure),
this button lets you perform the following tasks:
•Reset the switch to factory default settings but maintain the registration status:
All settings are erased and the switch restarts with factory default settings. The
NETGEAR registration status is maintained and not reset.
•Reset the switch to factory default settings and reset the registration status: All
settings are erased, the switch restarts with factory default settings, and the NETGEAR
registration status is reset. You must reregister the switch with NETGEAR.
To reset the switch:
1. Insert a tool such as a straightened paper clip into the opening.
2. Do one of the following:
•Reset the switch to factory default settings but maintain the registration
status: Press the Factory Defaults button for more than one second but less
than 10 seconds. (Do not press the button for more than 10 seconds!)
•Reset the switch to factory default settings and reset the registration status:
Press the Factory Defaults button for more than 10 seconds.
When the switch restarts, the Power LED lights yellow.
USB port
The switch provides one USB 2.0 port that lets you upgrade firmware from a disk, back
up the configuration to a storage device, and allow for the collection of a memory dump
for debugging purposes.
A device that you attach to the USB port must comply with the following requirements:
•The USB device must support USB 2.0.
•The USB device must support the FAT32 or VFAT file type. The NTFS file type is not
supported.
Because of hardware limitations, the write and read speed to and from a USB device is
about 1 Mbps.

Applications
The switch is designed to provide flexibility in configuring network connections. You
can use the switch as an aggregation switch in a larger network or as a backbone switch
in a small office or home office network to support 10 Mbps, 100 Mbps, and 1 Gbps
Ethernet and fiber routers, switches, and hubs. You can connect PoE and PoE+ devices
and non-PoE devices directly to the switch.
