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 networks. For model GS324TP, all RJ-45
ports support PoE+. Two or four additional fiber 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 21.
The switch provides administrative management options that let you configure, monitor,
and control the network. Using the local browser–based management interface, in this
guide referred to as the local browser interface, you can configure the switch and the
network, including the ports, the management VLAN, VLANs for traffic control, link
aggregation for increased bandwidth, Quality of Service (QoS) for prioritizing traffic,
and network security.
For initial discovery of the switch on the network, use one of the following methods, all
of which are described in detail in the user manual:
NETGEAR Insight mobile app
•
NETGEAR Smart Control Center Utility
•
NETGEAR Switch Discovery Tool
•
You can also get the IP address of the switch from the DHCP server in the network or
use an IP scanner utility.
After discovery, you can configure the switch using the local browser interface for
advanced setup and configuration of features, or the Smart Control Center program
for very basic setup. For more information, see the user manual, which you can download
from netgear.com/support/download/.
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.

S350 Series 24- (PoE+) and 48-Port Gigabit Ethernet Smart Managed Pro Switches
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 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.
All RJ-45 copper ports on model GS324TP support PoE+.
SFP ports for fiber connectivity
To enable fiber connections, SFP fiber ports accommodate standard small form-factor
pluggable (SFP) gigabit interface converters (GBICs, also referred to as transceiver
modules). GBICs are sold separately from the switch.
The switch supports the NETGEAR SFP transceiver modules that are listed in the following
table.

SFP transceiver 1000BASE-TAGM7341G Ethernet copper
For more information about NETGEAR SFP transceiver modules, visit
netgear.com/business/products/switches/modules-accessories.
Note: If you use a third-party passive direct-attach cable (DAC), the length of the cable
must not exceed 5 meters (16.4 feet).
Reset button
The switch provides a recessed Reset button on the front panel so that you can either
restart (power-cycle) the switch or return the switch to its factory default settings, causing
all custom settings to be erased.
To restart the switch or return the switch to its factory default settings:
1. Insert a device such as a straightened paper clip into the opening.
2.
Do one of the following:
Restart the switch. Press the Reset button for about two seconds. (Do not press
•
the button for more than five seconds!)
The switch restarts but retains its custom settings. During this process, the Power
LED lights amber.
Return the switch to its factory default settings. Press the Reset button for at
•
least five seconds.
The switch restarts and returns to its factory default settings. During this process,

Network switching
You can use the switch as a network switch to build a network that provides up to 1 Gbps
access to desktop computers, access points, non-PoE surveillance cameras, a NAS,
servers such as a file server, an IPTV, and so on. Connect the switch to a network router
that is connected to the Internet.
With 1 Gbps connections, the switch always functions in full-duplex mode. Any switch
port that is connected to a computer or file server can provide up to 2 Gbps bidirectional
throughput.
You must connect one LAN port on the switch to a LAN port on a network router (see
device 2 in the following figure) that is connected to the Internet (see 3). You can also
make a 1 Gbps fiber connection to a network router that supports fiber and that is
connected to the Internet.
If you connect a WiFi access point (see device 4 in the following figure) to the switch,
you can connect a tablet (see device 5) or smartphone (see device 6) to the WiFi network
and use NETGEAR Insight to discover the switch.

PoE overview (model GS324TP)
Model GS324TP supports twenty four Power over Ethernet plus (PoE+) ports. The switch
can supply up to 30W PoE+ (IEEE 802.3at) to each port up to its total maximum PoE
power budget of 190W across all active PoE+ ports. The switch is also compatible with
PoE (IEEE 802.3af).
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+-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 more than six PoE+ devices or more than twelve PoE devices
to active be simultaneously.
For more information about PoE, see the installation guide and user manual, both of
which you can download from netgear.com/support/download/.
PoE and network switching (model GS324TP)
Model GS324TP supports both PoE and non-PoE equipment. The following figure shows
an example of how you can connect a PoE WiFi access point (see device 4), a PoE IP
camera (see device 7), a PoE IP video phone (see device 8), and a PoE IP phone (see
device 9) to the switch. In the following figure, non-PoE equipment is also attached to
the switch (see devices 10 and 11).
You must connect one LAN port on the switch to a LAN port on a network router (see
device 2 in the following figure) that is connected to the Internet (see 3). You can also

Step 2: Protect against electrostatic discharge
WARNING: Static electricity can harm delicate components inside your switch. To
prevent static damage, discharge static electricity from your body before you touch any
of the electronic components. You can do so by periodically touching an unpainted
metal surface on the switch.
You can also take the following steps to prevent damage from electrostatic discharge
(ESD):
When unpacking a static-sensitive component from its shipping carton, leave it in
•
the antistatic package until you are ready to install it. Just before unwrapping the
antistatic package, discharge static electricity from your body.
Before moving a sensitive component, place it in an antistatic container or package.
•
Handle all sensitive components in a static-safe area. If possible, use antistatic floor
•
pads, workbench pads, and an antistatic grounding strap.

Optional Step 5: Install SFP transceiver modules
The following optional procedure describes how to install an optional SFP transceiver
module into one of the SFP ports. For information about SFP transceiver modules, see
SFP ports for fiber connectivity on page 19.
Note: Contact your NETGEAR sales office to purchase these modules. If you do not
want to install an SFP module, skip this procedure.
To install an SFP transceiver module:
1. Insert the transceiver into the SFP port.
On models GS324T and GSA324TP, the SFP ports are numbered 25F and 26F. On
model GS348T, the SFP ports are numbered 49F, 50F, 51F, and 52F.
You can install an SFP transceiver module in each SFP port.
2.
Press firmly on the flange of the module to seat it securely into the connector.
Step 6: Connect devices to the switch
The following procedure describes how to connect devices to the switch’s RJ-45 ports.
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). On model GS324TP, if you use a PoE connection and
the powered device (PD) receives insufficient PoE power from the switch, consider using
a shorter cable.
To connect devices to the switch’s RJ-45 ports:
1. Connect a device to an RJ-45 network port on the switch.
Models GS324T and GS348T support non-PoE devices. Model GS324TP supports
both PoE and non-PoE devices.
2.
Verify that all cables are installed correctly.
Hardware Installation Guide30Installation
Page 31
S350 Series 24- (PoE+) and 48-Port Gigabit Ethernet Smart Managed Pro Switches
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 AC power cable connection
controls the power.
Before connecting the AC power cable to the AC power receptacle on the switch, select
an AC outlet for the AC power cable. Make sure that the AC outlet is not controlled by
a wall switch, which can turn off power to the switch.
To apply power:
1.
Connect the plug of the AC power cable to the AC power receptacle on the back
of the switch.
2. Plug the AC power cable 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 yellow while the switch
starts. After about two minutes, the switch completes its startup process and the
Power LED turns from yellow to solid green.
If the Power LED does not light, check to see that the AC power cable is plugged in
correctly and that the power source is good.

S350 Series 24- (PoE+) and 48-Port Gigabit Ethernet Smart Managed Pro Switches
Step 9: Manage the switch
The switch contains built-in web browser–accessible software for viewing, changing,
and monitoring the way it functions. This management software is not required for the
switch to work. You can use the ports without using the management software. However,
the management software enables the setup of VLAN and trunking features and also
improves 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
local browser interface for advanced setup and configuration of features, or the Smart
Control Center program (which requires a Windows-based computer) for very basic
setup. For more information about managing the switch, 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/.
Note: The switch’s default IP address is 192.168.0.239 and its default subnet mask is
255.255.255.0. By default, the DHCP client of the switch is enabled.

PoE troubleshooting suggestions (model GS324TP)
Here are some tips for correcting PoE problems that might occur on model GS324TP:
Make sure that the PoE Max LED is off. If the PoE Max LED is solid yellow, 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 right port LED on the switch lights
solid green. If the right port LED lights solid yellow, a PoE fault occurred and PoE
halted because of one of the conditions that are listed in the following table.
Table 7. 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.
