Introduction
This hardware installation guide is for the following NETGEAR switch models:
•Insight Managed 28-Port Gigabit Ethernet Smart Cloud Switch with 2 SFP 1G & 2 SFP+ 10G Fiber Ports,
Model GC728X
•Insight Managed 28-Port Gigabit Ethernet PoE+ Smart Cloud Switch with 2 SFP 1G & 2 SFP+ 10G Fiber
Ports, Model GC728XP
The switch provides 24 Gigabit Ethernet RJ-45 copper ports, 2 dedicated Gigabit SFP fiber ports, and 2 dedicated
10G SFP+ fiber ports.
Model GC728XP supports Power over Ethernet Plus (PoE+) on all 24 RJ-45 copper ports so that you can let
the switch provide power to PoE-capable devices such as WiFi access points, VoIP phones, and IP security
cameras.Model GC728XP can supply up to 30W PoE (IEEE 802.3at) to each port, with a maximum PoE power
budget of 390W across all active PoE+ ports.
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
The switch provides 24 Gigabit Ethernet copper ports, 2 dedicated Gigabit SFP fiber ports, and 2 dedicated
10G SFP+ fiber ports.All copper ports use RJ-45 connectors.The SFP ports require a standard small
form-factor pluggable (SFP) gigabit interface converter (GBIC, also referred to as a transceiver module),
which is sold separately from the switch.The switch integrates full-duplex, nonblocking switch fabric that
provides full-wire speed for all packet sizes.
The PoE+ model supports PoE on all copper ports with a maximum PoE power budget of 390W across all
active PoE+ ports.
For information about application examples, see Applications on page 17.Note
The switch provides management options that let you discover the switch on the network and configure,
monitor, and control the switch:
•NETGEAR Insight app. Using the NETGEAR Insight app, you can discover the switch on the network
and add the switch to the NETGEAR Insight app so that you can set up the switch in the network and
manage and monitor the switch remotely from your smartphone.You can choose from four methods to
add the switch to the NETGEAR Insight app:You can scan your network for the switch, scan the QR
code or the barcode of the switch, or add the serial number of the switch.For more information, see the
NETGEAR knowledge base articles at netgear.com/support.
•Insight Cloud portal.Using the NETGEAR Insight Cloud portal, you can set up the switch in the network,
perform advanced remote management, monitor the switch, analyze the switch and network usage,
and, if necessary, troubleshoot the switch and the network.
•Local browser–based management interface.By default, the management mode of the switch is set
to NETGEAR Insight App.With this setting you can manage the switch using the Insight app or the
Insight Cloud portal. For complex tasks such as integrating with an existing network of devices that are
not managed through Insight, and for debugging purposes, you can change the management mode of
the switch to PC Web-browser and access the local browser interface.In this mode, you can change
the settings of the specific device, but we recommend that you do not use this mode to change settings
that are Insight manageable because they would not be synchronized with Insight or to the network
location and other devices to which you assigned the switch.
Changes to Insight-manageable settings from the local browser interface might also
create conflicts with the rest of the Insight-managed network to which the device is
connected.While you manage the switch with the local browser interface, you cannot
use the Insight app or Insight Cloud portal.To reenable management of the device
remotely or through the cloud, you can return the management mode to NETGEAR
Insight App at any time so that you can manage the switch with the Insight app or
Insight Cloud portal.
Note
For more information about the local browser interface, see the user manual, which you can download
from downloadcenter.netgear.com.

Theswitchisdesigned formanagementbytheNETGEAR Insight appona smartphone
or tablet.Alternatively, you can manage the switch from the Insight Cloud portal that
is available from a web browser on your Windows-based computer, Mac, or tablet.
By default, the local browser interface is disabled and you cannot use it while the
switch is managed by the NETGEAR Insight app or Insight Cloud portal.
Note
You can install the switch freestanding (on a desktop) or in a standard 19-inch rack, using the included
rack-mount kit.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 Gigabit Ethernet
and Fast Ethernet.
For Gigabit Ethernet connections, use Category 5 (Cat 5) or higher-rated Ethernet cables terminated with
RJ-45 connectors.

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.
•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 the supplied DC power adapter. If you were not provided with a DC power adapter, contact
your reseller.
•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.
