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, 390W PoE, Model GC728XP
•Insight Managed 52-Port Gigabit Ethernet Smart Cloud Switch with 2 SFP 1G & 2
SFP+ 10G Fiber Ports, Model GC752X
•Insight Managed 52-Port Gigabit Ethernet PoE+ Smart Cloud Switch with 2 SFP 1G
& 2 SFP+ 10G Fiber Ports, 505W PoE, Model GC752XP
The switch provides 24 or 48 Gigabit Ethernet RJ-45 copper ports, 2 dedicated Gigabit
SFP fiber ports, and 2 dedicated 10G SFP+ fiber ports.
Models GC728XP and GC752XP support Power over Ethernet Plus (PoE+) on all 24 or
48 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. These models
can supply up to 30W PoE (IEEE 802.3at) to each port. Model GC728XP provides a
maximum PoE power budget of 390W across all active PoE+ ports. Model GC752XP
provides a maximum PoE power budget of 505W 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
• Features
• Safety Instructions and Warnings

Overview
The switch provides 24 or 48 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+ models supports PoE on all copper ports with a maximum PoE power budget
of 390W (model GC728XP) or 505W (model GC752XP) across all active PoE+ ports.
Note: For information about application examples, see Applications on page 31.
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.

Insight Managed 28-Port and 52-Port Gigabit Ethernet (PoE+) Smart Cloud Switch

Note: 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.
For more information about the local browser interface, see the user manual, which
you can download from downloadcenter.netgear.com.
Note: The switch is designed for management by the NETGEAR Insight app on a
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.
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 5e (Cat 5e) or higher-rated Ethernet
cables terminated with RJ-45 connectors.
Features
The switch includes the following key hardware features:
•Twenty-four (models GC728X and GC728XP) or forty-eight (models GC752X and
GC752XP) Gigabit Ethernet ports.
