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 may 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, 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.

ManagedStackableSwitchesGSM7200PSandGSM7300SSeriesHardwareInstallationGuide
• 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
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.

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):
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 installing the
switch.
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
<pdf>“Select a Location” on page 2-19.
3. Remove all packing material.
4. Make sure that all items are present. See “Package Contents” on page 2-17.
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.

ManagedStackableSwitchesGSM7200PSandGSM7300SSeriesHardwareInstallationGuide
1. Select a Location. See “Select a Location” on page 2-19.
2. Install the Switch. See “Install the Switch” on page 2-20.
3. Check the installation. See “Check the Installation” on page 2-20.
4. Apply power and check the LEDs. See “Connect to Power and Check the LEDs” on
page 2-21.
Select 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 may greatly affect its performance. Before installing the
switch or switches, make sure that the chosen installation location meets the following site
requirements.
Table 2-1. 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. You need the
rack-mount kit supplied with your switch.
Access Locate 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 50ºC (32º and 122ºF).
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 intend
to 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.

Install 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.
Installing the Switch in a Rack
To install the switch in a rack, you will need the 19-inch rack-mount kit supplied with your
switch.
1. Attach the supplied mounting brackets to the side of the switch.
2. Use the provided Phillips head screws to fasten the brackets to the sides of the
switch.
