Insight Managed 28-Port and 52-Port Gigabit Ethernet (PoE+) Smart Cloud Switch
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 22.
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
mobile device. 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 type in 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. The Insight Cloud portal is available to Insight Premium and Insight
Pro subscribers. A free trial of Insight Premium is available for new customers.
Local browser user interface (UI). By default, the management mode of the switch
•
is set to NETGEAR Insight. 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 use the local browser UI to change the management
mode of the switch to Direct Connect Web-browser Interface (Local LAN Only). In
this mode, you can change the settings of the specific switch, but we recommend
that you do not use this mode to change settings that are Insight manageable because
they will not be synchronized with Insight or to the network location and other devices
to which you assigned the switch.
Hardware Installation Guide7Introduction
Page 8
Insight Managed 28-Port and 52-Port Gigabit Ethernet (PoE+) Smart Cloud Switch
Note: Changes to Insight-manageable settings from the local browser UI 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 UI, 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 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 UI, see the user manual, which you
can download from netgear.com/support/download.
Note: The switch is designed for management by NETGEAR Insight: You can use
the NETGEAR Insight app on your mobile device or the Insight Cloud portal from a
web browser on your Windows-based computer, Mac, or tablet. By default, the local
browser UI is disabled and you cannot use it while the switch is managed by NETGEAR
Insight.
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.

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 ascertains 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.
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.

PoE overview
Model GC728XP supports 24 Power over Ethernet Plus (PoE+) ports and can supply up
to 30W PoE+ (IEEE 802.3at) to each port up to its total maximum PoE power budget of
390W across all active PoE+ ports.
Model GC752XP supports 48 Power over Ethernet Plus (PoE+) ports and can supply up
to 30W PoE+ (IEEE 802.3at) to each port up to its total maximum PoE power budget of
505W across all active PoE+ ports.
These models are backward compatible with PoE (IEEE 802.3af).
By default, the supplied power is prioritized according to the port order, up to the total
power budget of the device. For model GC728XP, port 1 receives the highest PoE
priority, while port 24 is relegated to the lowest PoE priority. For model GC752XP, port
1 receives the highest PoE priority, while port 48 is relegated to the lowest PoE priority.
Note: For both models, you can override the default PoE power settings, prioritize the
ports in any order, and specify the exact power that is allotted to each port (see below).
If the power requirements for attached devices exceed the total power budget of the
switch, the PoE power to the device on the highest-numbered active PoE+ port is
disabled to make sure that the devices connected to the higher-priority, lower-numbered
PoE+ ports are supported first.
Although a device is listed as an 802.3at PoE+–powered or 802.3af PoE–powered device,
it might not require the maximum power limit that is specified by its IEEE standard. Many
devices require less power, allowing all 24 (model GC728XP) or 48 (model GC752XP)
PoE+ ports to be active simultaneously when the devices correctly report their PoE class
to the switch.
Using the advanced PoE controls in the NETGEAR Insight mobile app and Insight Cloud
portal, you can control how PoE power is allocated across active PoE+ ports by overriding
the default or autodetected PoE power limits for individual PoE+ ports. You can also
specify the exact PoE power limit per port from 3.0W to 30.0W.

2.
Verify that all cables are installed correctly.
Step 7: Check the installation
Before you apply power to the switch, perform the following steps.
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. Make sure that all equipment is mounted properly and securely.
Step 8: Apply power and check the LEDs
The switch does not provide an on/off power switch. The power cord connection controls
the power.
Before connecting the power cord, select an AC outlet that is not controlled by a wall
switch, which can turn off power to the switch.
To apply power:
1.
Connect the end of the power cord to the AC power receptacle on the back of the
switch.
2. Plug the AC power cord into a power source such as a wall socket or power strip.
3. Check to see that the LEDs on the switch light correctly.
When you apply power, the Power LED on the switch front panel lights and the port
LEDs for attached devices light.
Note: After you apply power, the Power LED lights solid amber while the switch
starts. After two or three minutes, the switch completes its startup process and the
Power LED turns from amber to solid green.
If the Power LED does not light, check to see that the power cord is plugged in
correctly and that the power source is good.

Step 9: Manage the switch
Using the NETGEAR Insight app and Insight Cloud portal, you can discover the switch
on the network and add the switch to the Insight app and Insight Cloud portal so that
you can perform setup, remote management, and monitoring tasks from your
smartphone, tablet, or computer.
The switch is a plug-and-play device that starts switching as soon as you plug it into
power and your network. You can use the switch without creating an Insight-managed
topology (using the Insight app or Insight Cloud portal), but in that situation you cannot
remotely monitor, manage, and troubleshoot the switch, nor receive push notifications
from the switch, and the switch operates in standalone mode only, like a traditional
NETGEAR Smart Managed Pro Switch.
Using the Insight app and Insight Cloud portal, as well as network-based policies and
zero-touch deployment and configuration, you can configure and manage the switch,
along with Insight-managed WiFi access points and NAS devices, at the network level.
Also, using the Insight app or Insight Cloud portal, you can set up features such as
VLANs and trunking and improve the efficiency of the switch, which results in the
improvement of its overall performance as well as the performance of the network.
After you power on the switch for the first time, you can configure the switch using the
Insight app or Insight Cloud portal.
For more information about Insight, visit netgear.com/insight and see the NETGEAR
knowledge base articles at netgear.com/support.
For information about managing the switch without the benefits of the Insight app and
Insight Cloud portal, see the user manual, which you can download from
netgear.com/support/download.
Note: The switch’s default IP address is 192.168.0.239 and its default subnet mask is
255.255.255.0.

PoE troubleshooting suggestions
Here are some tips for correcting PoE problems that might occur:
Make sure that the PoE Max LED is off. If the PoE Max LED is solid amber, disconnect
•
one or more PoE devices to prevent PoE oversubscription. Start by disconnecting
the device from the highest-numbered port.
Make sure that the Ethernet cables are plugged in correctly. For each powered
•
device (PD) that is connected to the switch, the associated right port LED on the
switch lights solid green. If the right port LED lights solid amber, a PoE fault occurred
and PoE halted because of one of the conditions that are listed in the following table.
Table 8. PoE fault conditions and possible solutions
Possible SolutionPoE Fault Condition
A PoE-related short circuit occurred on the port.
The PoE power demand of the PD exceeded the maximum level that the
switch permits. The maximum level is 15.4W for a PoE connection or
30W for a PoE+ connection.
The PoE current on the port exceeded the classification limit of the PD.
The PoE voltage of the port is outside the range that the switch permits.
The problem is most likely with the
attached PD. Check the condition
of the PD or restart the PD by
disconnecting and reconnecting
the PD.
Restart the switch to see if the
condition resolves itself.
Additional troubleshooting suggestions
If the suggestions in the troubleshooting chart do not resolve the problem, see the
following troubleshooting suggestions:
Network adapter cards. Make sure that the network adapters that are installed in
•
the computers are in working condition and the software driver was installed.
Configuration. If problems occur after you alter the network configuration, restore
•
the original connections and determine the problem by implementing the changes,
one step at a time. Make sure that cable distances, repeater limits, and other physical
aspects of the installation do not exceed the Ethernet limitations.
Switch integrity. If necessary, verify the integrity of the switch by resetting it. To
•
reset the switch, disconnect the power from the switch and then reconnect the power.
