24-Port Gigabit (Hi-Power) PoE+ Ethernet Smart Managed Pro Switch with 2 SFP Ports
Overview
The switch provides twenty-four 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+.
Two additional ports can accept small form-factor pluggable (SFP) gigabit interface
converters (GBICs) for 1G fiber connectivity.
Note: For information about application samples, see Applications on page 19.
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.
Management options
The switch provides management options that let you discover the switch on the network
and configure, monitor, and control the switch:
Local browser–based management interface. By default, the management mode
•
of the switch is set to Directly Connect to Web Browser Interface, which lets you
access the local browser–based management interface (in this guide referred to as
the local browser interface). In this mode, you can change all settings of the switch.
For more information about the local browser interface, see the user manual, which
you can download from netgear.com/support/download/.
Note: If you plan to use the NETGEAR Insight app or Insight Cloud portal to manage
the switch, we recommend that you do not use the local browser interface 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.
NETGEAR Insight app and Insight Cloud portal. 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:
- NETGEAR Insight app. With 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 or tablet. You can choose from four methods to
Hardware Installation Guide6Introduction
Page 7
24-Port Gigabit (Hi-Power) PoE+ Ethernet Smart Managed Pro Switch with 2 SFP Ports
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.
- Insight Cloud portal. As an Insight Premium or Insight Pro subscriber, you can
use the NETGEAR Insight Cloud portal to set up the switch in the network, perform
advanced remote setup, configuration, and management, monitor the switch,
analyze the switch and network usage, and, if necessary, troubleshoot the switch
and the network.
For more information about NETGEAR Insight, visit netgear.com/insight and see the
NETGEAR knowledge base articles at netgear.com/support.
By default, the management mode is set to Directly Connect to Web Browser Interface
(which is the same as the local browser interface). 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 app or the Insight Cloud portal.
However, if you added the switch to a network on the Insight app or Insight portal
before, all Insight-manageable device settings are returned to the last configuration
saved on the cloud server, including the switch password (that is, the password is
reset to the Insight network password).
Note: If you use the NETGEAR 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 local browser interface for settings that are
not Insight-manageable, for complex 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 cloud server.
Any changes that you make using the Directly Connect to Web Browser Interface
management mode are not saved to the cloud server.

Figure 3. Back panel
RJ-45 Ports for 10/100/1000BASE-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) unshielded twisted-pair (UTP) 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 the need to set up uplink
connections while eliminating concern about whether to use crossover or
straight-through cables when you attach devices.
All RJ-45 ports also support Power over Ethernet (PoE+, IEEE 802.3at). The switch can
supply up to 30W PoE+ to each port. The maximum PoE power budget across all active
PoE+ ports is 190W for model GS724TPv2 and 380W for model GS724TPP.
Hardware Installation Guide15Hardware Overview
Page 16
24-Port Gigabit (Hi-Power) PoE+ Ethernet Smart Managed Pro Switch with 2 SFP Ports
SFP ports for fiber connectivity
To enable fiber connections on the switch, SFP+ fiber ports accommodate standard
small form-factor pluggable (SFP) gigabit interface converters (GBICs, also referred to
as transceiver modules) for 1G fiber connectivity. GBICs are sold separately from the
switch.
The switch supports the following NETGEAR ProSAFE SFP short-reach transceiver
modules:
AGM731F SFP transceiver 1000BASE-SX, SFP short-reach multimode LC GBIC

Page 20
24-Port Gigabit (Hi-Power) PoE+ Ethernet Smart Managed Pro Switch with 2 SFP Ports
PoE overview
The switch supports 24 Power over Ethernet plus (PoE+) ports. The switch can supply
up to 30W PoE+ (IEEE 802.3at) to each port. The maximum PoE power budget across
all active PoE+ ports is 190W for model GS724TPv2 and 380W for model GS724TPP.
Supplied power is prioritized according to the port order, up to the total power budget
of the device. Port 1 receives the highest PoE priority, while port 24 is relegated to the
lowest PoE priority.
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 PoE ports to be active simultaneously when
the devices correctly report their PoE class to the switch.
The following table shows the standard power ranges, calculated with the maximum

provide ventilation space between stacked switches.
Optional Step 5: Install an SFP transceiver module
The following optional procedure describes how to install an optional SFP transceiver
module into one of the SFP ports of the switch.
Note: Contact your NETGEAR sales office to purchase these modules. If you do not
want to install an SFP module, skip this procedure.
Hardware Installation Guide28Installation
Page 29
24-Port Gigabit (Hi-Power) PoE+ Ethernet Smart Managed Pro Switch with 2 SFP Ports
To install an SFP transceiver module:
1. Insert the transceiver into the SFP port.
Use port 25F or 26F.
2.
Press firmly on the flange of the module to seat it securely into the connector.
Step 6: Connect devices to the switch’s RJ-45 ports
All RJ-45 ports on the switch support PoE+. For application examples and information
about PoE, see Applications on page 19.
The switch supports Auto Uplink technology, which allows you to attach devices using
either straight-through or crossover cables. Use a Category 5 (Cat 5), Cat 5e, or Cat 6
cable that is terminated with an RJ-45 connector.
Note: Ethernet specifications limit the cable length between the switch and the attached
device to 328 feet (100 meters).
To connect devices to the switch’s RJ-45 ports:
1. Attach PoE and non-PoE devices to the switch.
2.
Verify that all cables are installed correctly.
Hardware Installation Guide29Installation
Page 30
24-Port Gigabit (Hi-Power) PoE+ Ethernet Smart Managed Pro Switch with 2 SFP Ports
Step 7: Check the installation
Before you apply power to the switch, perform the steps that are described in this
section.
To check the installation:
1. Inspect the equipment thoroughly.
2.
Verify again 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 AC power and check the LEDs
The switch does not provide an on/off 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 AC 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 front panel of the switch light correctly.
When you apply power, the Power LED on the switch front panel lights and the ports
LEDs for attached devices light. For information about the LEDs, see LEDs on page
14.
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
The switch is a plug-and-play device that starts switching as soon as you plug it into
power and your network.
After you complete the initial log-in procedure, you can configure the switch using the
local browser interface. After you complete the initial log-in procedure, you can also
change the management mode so that you configure the switch using the Insight app,
or if you are an Insight Premium or Insight Pro subscriber, the Insight Cloud portal. For
more information, see Management options on page 6.
For more information about managing the switch using the local browser interface,
including information about tools to discover the switch IP address in your network, see
the user manual, which you can download from netgear.com/support/download/.
For more information about NETGEAR Insight, visit netgear.com/insight and see the
NETGEAR knowledge base articles at netgear.com/support.
For very basic setup and management, you can use the Smart Control Center (SCC)
utility (which requires a Windows-based computer). For information about the SCC
utility, see netgear.com/support/product/SCC.
Note: By default, the DHCP client of the switch is enabled. If the switch cannot get an
IP address from a DHCP server, the switch’s default IP address is 192.168.0.239 and the
default subnet mask is 255.255.255.0.

that might occur.
Table 5. Troubleshooting chart
Possible SolutionPossible CauseSymptom
The Power LED is off.
The combined speed and
activity LED is off when the
port is connected to a device.
A file transfer is slow or
performance is degraded.
A segment or device is not
recognized as part of the
network.
Power is not supplied to the
switch.
The port connection is not
working.
One possible cause is that a
broadcast storm occurred and
that a network loop
(redundant path) was created.
One or more devices are not
properly connected, or
cabling does not meet
Ethernet guidelines.
Check the power cable connections at the
•
switch and the power source.
Make sure that all cables are used correctly and
•
comply with the Ethernet specifications.
Check the crimp on the connectors and make
•
sure that the plug is properly inserted and
locked into the port at both the switch and the
connecting device.
Make sure that all cables are used correctly and
•
comply with the Ethernet specifications.
Check for a defective port, cable, or module
•
by testing them in an alternate environment
where all products are functioning.
Break the loop by making sure that only one path
exists from any networked device to any other
networked device. After you connect to the switch
web management interface, you can configure
the Spanning Tree Protocol (STP) to prevent
network loops.
Verify that the cabling is correct.
•
Make sure that all connectors are securely
•
positioned in the required ports. It is possible
that equipment was accidentally disconnected.
The combined speed and
activity LEDs are blinking
continuously for all connected
ports and the network is
disabled.
A network loop (redundant
path) was created.
Break the loop by making sure that only one path

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 lower port LED on the
switch lights solid green. If the lower 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 6. 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 new
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.

If the problem continues, contact NETGEAR technical support. For more information,
visit the support website at netgear.com/support/.
Autonegotiation. The RJ-45 ports negotiate the correct duplex mode, speed, and
•
flow control if the device at the other end of the link supports autonegotiation. If the
device does not support autonegotiation, the switch determines only the speed
correctly, and the duplex mode defaults to half-duplex.
The Gigabit Ethernet ports negotiate speed, duplex mode, and flow control if the
attached device supports autonegotiation.
