Safety Instructions

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:

• 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. Only a trained service technician

should service 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 has fallen into the product.

-The product has been exposed to water.

-The product has been 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, contact technical support or 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 help avoid damaging your system, be sure that the voltage selection switch (if

provided) on the power supply is set to match the power available at your location:

-115 volts (V), 60 hertz (Hz) in most of North and South America and some Far

Eastern countries such as South Korea and Taiwan

-100 V, 50 Hz in eastern Japan and 100 V, 60 Hz in western Japan

-230 V, 50 Hz in most of Europe, the Middle East, and the Far East

• Also, be sure that attached devices are electrically rated to operate with the power

available in your location.

• Use only approved power cables. If you have not been provided with a power cable for

your system or for any AC-powered option intended for your system, purchase a power

Introduction

ProSafe™ 24-Port Managed Switch JGSM7224

cable that is approved for use in your country. The power cable must be rated for the

product and for the voltage and current marked on the product’s electrical ratings label.

The voltage and current rating of the cable should 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.

• Move products with care; ensure that all casters and stabilizers are firmly connected to

the system. Avoid sudden stops and uneven surfaces.

• Installation Guide

Protecting Against Electrostatic Discharge

WARNING!

Static electricity can harm delicate components inside your

system. To prevent static damage, discharge static electricity

from your body before you touch any of the electronic

components, such as the microprocessor. 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):

Hardware Installation

ProSafe™ 24-Port Managed Switch JGSM7224

1. 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.

2. Before moving a sensitive component, place it in an antistatic container or package.

3. Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads,

workbench pads, and an antistatic grounding strap.

Unpacking the Hardware

Check the contents of the boxes to make sure that all items are present before beginning the

installation.

1. Place the container on a clean flat surface, and cut all straps securing the container.

2. Unpack the hardware from the boxes.

Carefully remove the hardware, and place it on a secure and clean surface. See

Selecting a Location on page 10.

3. Remove all packing material.

4. Make sure that all items are present. See Package Contents on page 8.

Note: If any item is found missing or damaged, contact your local

NETGEAR reseller for replacement.

5. Inspect the products and accessories for damage. Report any damage immediately.

Installation

Install the equipment in the following sequence, as presented in this chapter:

1. Select a location. See the following section, Selecting a Location .”

2. Install the switch. See Installing the Switch on page 10.

3. Check the installation. See Checking the Installation on page 11.

4. Apply power and check the LEDs. See Connecting to Power and Check the LEDs on

page 12.

Hardware Installation

ProSafe™ 24-Port Managed Switch JGSM7224

Selecting a Location

The switch can be mounted in a standard 19-inch (48.26-centimeter) rack, wall mounted, or

left freestanding (placed on a tabletop). The site where you install the switch can greatly

affect its performance. Before installing the switch or switches, make sure that the chosen

installation location meets the following site requirements.

Table 1. Site Requirements for Switch Location

Requirements

Mounting • Desktop Installations. Provide a flat table or shelf surface.

• Rack-mount Installations. Use a 19-inch (48.3-centimeter) EIA standard

equipment rack that is grounded and physically secure, and the rack-mounting kit

supplied with your switch.

Access Put the switch in a position that lets you access the front panel RJ-45 ports, view the

front panel LEDs, and access the rear panel power connector.

Power source Provide a power source within 6 feet (1.8 meters) of the installation location. Power

specifications for the switch are shown in Appendix A.” Be sure that the AC outlet is

not controlled by a wall switch, which can accidentally turn off power to the outlet and

the switch.

Environment Install the switch in a site free from strong electromagnetic field generators (such as

motors), vibration, dust, and direct exposure to sunlight.

Temperature The ambient switch operating temperature range is 0º to 55ºC (32º and 131ºF). Keep

the switch away from heat sources such as direct sunlight, warm-air exhausts, hot-air

vents, and heaters.

Operating humidity Install the switch in a dry area with a maximum relative humidity of 90%,

noncondensing.

Ventilation Do not restrict airflow by covering or obstructing air inlets on the sides of the switch.

Keep at least 2 inches (5.08 centimeters) free on all sides for cooling. Be sure that

there is adequate airflow in the room or wiring closet where you will install the switch.

Cabling Route the cable to avoid sources of electrical noise such as radio transmitters,

broadcast amplifiers, power lines, and fluorescent lighting fixtures.

Installing the Switch

You can install the switch on a flat surface or in a standard 19-inch rack.

Installing the Switch on a Flat Surface

The switch ships with four self-adhesive rubber footpads. Stick one rubber footpad on each of

the four concave spaces on the bottom of the switch. The rubber footpads cushion the switch

against shock and vibrations.
