Overview
The switch provides forty-eight 10/100/1000M BASE-T RJ-45 copper ports that support nonstop Layer 2
networks.Two additional ports can accept small form-factor pluggable (SFP) 100M or 1G fiber optical
modules.
You can create high-speed connections using the 1G ports.For example, you can do the following:
•Connect switches to each other with high-speed links (using link aggregation)
•Link to high-speed servers
•Provide 10/100/1000M copper and 100M or 1G fiber connectivity
The switch provides administrative management options that let you configure, monitor, and control the
network. Using the web management interface, you can configure the switch, and the network, including
the ports, the managementVLAN,VLANs for traffic control, link aggregation for increased bandwidth, Quality
of Service (QoS) for prioritizing traffic, and network security.
You can use the web browser-based management interface to enable initial discovery of the switch on the
network and to configure the switch, or you can install the configuration utility on your Windows-based
computer. If you do not use a Windows-based computer, get the IP address of the switch from the DHCP
server in the network or use an IP scanner utility.
The configuration utility runs on Windows-based computers.Visit
netgear.com/support/product/PCU to download the utility to configure your switch.
Note
After discovery, you can configure the switch using the web management interface or the configuration utility
for basic or advanced setup. For more information, see the user manual which you can download from
downloadcenter.netgear.com.
You can install the switch on a desktop or rack-mount it in a wiring closet or equipment room.The switch is
IEEE compliant and offers low latency for high-speed networking. 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 1-Gigibit
connections.
Features
The switch includes the following key hardware features:
•Forty-eight 10M/100M/1G Ethernet ports.
•Two dedicated SFP fiber ports.
•MAC table size of 16K entries.
•100 Gbps switch fabric full duplex nonblocking.
•System password.
•DHCP client.

Safety Instructions andWarnings
Use the following safety guidelines to ensure your own personal safety and to help protect your system from
potential damage.
To reduce the risk of bodily injury, electrical shock, fire, and damage to the equipment, observe the following
precautions:
•This product is designed for indoor use only in a temperature-controlled (0–50°C) and humidity-controlled
(90 percent maximum relative humidity, noncondensing) environment.
Introduction

48-Port Gigabit Ethernet Smart Managed Plus Switch

Any device that is located outdoors and connected to this product must be properly grounded and surge
protected.
To the extend permissible by applicable law, failure to follow these guidelines can result in damage to
your NETGEAR product, which might not be covered by NETGEAR’s warranty.
•Observe and follow service markings:
-Do not service any product except as explained in your system documentation.
-Opening or removing covers that are marked with the triangular symbol with a lightning bolt can
expose you to electrical shock.We recommend that only a trained technician services components
inside these compartments.
•If any of the following conditions occur, unplug the product from the electrical outlet and replace the part
or contact your trained service provider:
-The power cable, extension cable, or plug is damaged.
-An object fell into the product.
-The product was exposed to water.
-The product was dropped or damaged.
-The product does not operate correctly when you follow the operating instructions.
•Keep your system away from radiators and heat sources. Also, do not block cooling vents.
•Do not spill food or liquids on your system components, and never operate the product in a wet
environment.If the system gets wet, see the appropriate section in your troubleshooting guide, or contact
your trained service provider.
•Do not push any objects into the openings of your system.Doing so can cause fire or electric shock by
shorting out interior components.
•Use the product only with approved equipment.
•Allow the product to cool before removing covers or touching internal components.
•Operate the product only from the type of external power source indicated on the electrical ratings label.
If you are not sure of the type of power source required, consult your service provider or local power
company.
•To avoid damaging your system, be sure that the voltage selection switch (if provided) on the power
supply is set to match the power at your location:
-115V, 60 Hz in most of North and South America and some Far Eastern countries such as South
Korea and Taiwan
-100V, 50 Hz in eastern Japan and 100V, 60 Hz in western Japan
-230V, 50 Hz in most of Europe, the Middle East, and the Far East
•Be sure that attached devices are electrically rated to operate with the power available in your location.
•Use only approved power cables. If you were not provided with a power cable for your system or for
any AC-powered option intended for your system, purchase a power cable approved for your country.
The power cable must be rated for the product and for the voltage and current marked on the product
Introduction

electrical ratings label.The voltage and current rating of the cable must be greater than the ratings
marked on the product.
•To help prevent electric shock, plug the system and peripheral power cables into properly grounded
electrical outlets.
•The peripheral power cables are equipped with three-prong plugs to help ensure proper grounding. Do
not use adapter plugs or remove the grounding prong from a cable.If you must use an extension cable,
use a three-wire cable with properly grounded plugs.
•Observe extension cable and power strip ratings.Make sure that the total ampere rating of all products
plugged into the extension cable or power strip does not exceed 80 percent of the ampere ratings limit
for the extension cable or power strip.
•To help protect your system from sudden, transient increases and decreases in electrical power, use a
surge suppressor, line conditioner, or uninterruptible power supply (UPS).
•Position system cables and power cables carefully. Route cables so that they cannot be stepped on or
tripped over. Be sure that nothing rests on any cables.
•Do not modify power cables or plugs. Consult a licensed electrician or your power company for site
modifications.
•Always follow your local and national wiring rules.
