Introduction
This hardware installation guide is for the following NETGEAR switches:
•S350 Series 8-Port Gigabit Ethernet Smart Managed Pro Switch (GS308T)
This model provides eight Gigabit RJ-45 copper ports.
•S350 Series 8-Port Gigabit PoE+ Ethernet Smart Managed Pro Switch with 2 SFP
Ports (GS310TP)
This model provides eight Gigabit PoE+ RJ-45 copper ports and two dedicated SFP
fiber ports. Power over Ethernet (PoE) lets you provide power to PoE-capable devices
such as WiFi access points, VoIP phones, and IP security cameras so that you do not
need to use power supplies for those devices. The switch can supply up to 30W
PoE+ (IEEE 802.3at) to each copper port, with a maximum PoE power budget of
55W across all active PoE+ copper 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 eight 10/100/1000BASE-T RJ-45 copper ports that support nonstop
10/100/1000M Layer 2 networks. For model GS310TP, all RJ-45 ports support PoE+.
Also for model GS310TP, 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 18.
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 management 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 management 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/.
The switch is designed for freestanding desktop use. 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.

Hardware Installation Guide15Hardware Overview
S350 Series 8-Port Gigabit Ethernet Smart Managed Pro 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 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 GS310TP support PoE+.
Reset button
The switch provides a recessed Reset button on the front panel so that you can either
restart (power-cylce) 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 yellow.
Hardware Installation Guide16Hardware Overview
S350 Series 8-Port Gigabit Ethernet Smart Managed Pro Switch

•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,
the Power LED lights yellow.

Applications
The switch is designed to provide flexibility in configuring network connections. The
switch can be used as your only network traffic–distribution device for PoE and non-PoE
devices or with 10 Mbps, 100 Mbps, and 1 Gbps Ethernet and fiber hubs, routers, access
point, and other switches.
This chapter includes the following sections:
• Desktop switching
• PoE overview (model GS310TP)
• PoE and desktop switching (model GS310TP)
18

Desktop switching
You can use either model GS308T or model GS310TP as a desktop switch to build a
small network that provides up to 1 Gbps access to desktop computers, non-PoE
surveillance cameras, a NAS, servers such as a file server, an IPTV, and so on. In a small
network such as a small office or home office network, connect the switch to a router
that, in turn, is connected to an Internet modem.
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 (for example, port 8 in the following
figure) to a LAN port on the router. For model GS310TP, you can also make a 1 Gbps
fiber connection to a router that supports fiber and that is connected to the Internet.
Figure 5. Sample desktop switching with model GS308T
PoE overview (model GS310TP)
Model GS310TP supports eight 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 55W 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 8 is relegated to the
lowest PoE priority.
Hardware Installation Guide19Applications
S350 Series 8-Port Gigabit Ethernet Smart Managed Pro Switch

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 all eight PoE+ ports to be active simultaneously when the
devices correctly report their PoE class to the switch.
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 desktop switching (model GS310TP)
Model GS310TP supports both PoE and non-PoE equipment. The following figure shows
an example of how you can connect a PoE wireless access point (see port 1), a PoE
surveillance camera (see port 2), a PoE IPTV phone (see port 3), and a PoE VoIP phone
(see port 4) to the switch. Non-PoE equipment is attached to ports 5, 6, and 7.
You must connect one LAN port on the switch (for example, port 8 in the following
figure) to a LAN port on the router. You can also make a 1 Gbps fiber connection from
port 9F or port 10F to a router that supports fiber and that is connected to the Internet.
