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.

2-8 Introduction
v1.0, March 2006
• 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.
• Move products with care; ensure that all casters and stabilizers are firmly
connected to the system. Avoid sudden stops and uneven surfaces.

v1.0, March 2006
Protecting Against Electrostatic Discharge
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
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
“Select a Location” on page 3-4.
3. Remove all packing material.
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.

3-4 Hardware Installation
v1.0, March 2006
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 3-1. 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, “Technical Specifications”. 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 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.
