• 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 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 cable(s). 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.

DGS-3224TGR Gigabit Ethernet Switch User’s Guide
Safety Instructions (continued)
• To help prevent electric shock, plug the system and peripheral power cables into properly grounded electrical outlets.
These 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 3-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/national wiring rules.
• When connecting or disconnecting power to hot-pluggable power supplies, if offered with your system, observe the
following guidelines:
– Install the power supply before connecting the power cable to the power supply.
– Unplug the power cable before removing the power supply.
– If the system has multiple sources of power, disconnect power from the system by
unplugging all power cables from the power supplies.
• Move products with care; ensure that all casters and/or stabilizers are firmly connected to the system. Avoid sudden
stops and uneven surfaces.
General Precautions for Rack-Mountable Products
Observe the following precautions for rack stability and safety. Also refer to the rack installation documentation
accompanying the system and the rack for specific caution statements and procedures.
Systems are considered to be components in a rack. Thus, "component" refers to any system as well as to various peripherals
or supporting hardware.
CAUTION: Installing systems in a rack without the front and side stabilizers
installed could cause the rack to tip over, potentially resulting in bodily injury under
certain circumstances. Therefore, always install the stabilizers before installing
components in the rack.
After installing system/components in a rack, never pull more than one component
out of the rack on its slide assemblies at one time. The weight of more than one
extended component could cause the rack to tip over and may result in serious
injury.
• Before working on the rack, make sure that the stabilizers are secured to the rack, extended to the floor, and that the
full weight of the rack rests on the floor. Install front and side stabilizers on a single rack or front stabilizers for
joined multiple racks before working on the rack.

DGS-3224TGR Gigabit Ethernet Switch User’s Guide
Safety Instructions (continued)
Always load the rack from the bottom up, and load the heaviest item in the rack first.
Make sure that the rack is level and stable before extending a component from the rack.
Use caution when pressing the component rail release latches and sliding a component into or out of a rack; the slide rails can
pinch your fingers.
After a component is inserted into the rack, carefully extend the rail into a locking position, and then slide the component into
the rack.
Do not overload the AC supply branch circuit that provides power to the rack. The total rack load should not exceed 80
percent of the branch circuit rating.
Ensure that proper airflow is provided to components in the rack.
Do not step on or stand on any component when servicing other components in a rack.
NOTE: A qualified electrician must perform all connections to DC power and to
safety grounds. All electrical wiring must comply with applicable local or national
codes and practices.
CAUTION: Never defeat the ground conductor or operate the equipment in the
absence of a suitably installed ground conductor. Contact the appropriate electrical
inspection authority or an electrician if you are uncertain that suitable grounding is
available.
CAUTION: The system chassis must be positively grounded to the rack cabinet
frame. Do not attempt to connect power to the system until grounding cables are
connected. Completed power and safety ground wiring must be inspected by a
qualified electrical inspector. An energy hazard will exist if the safety ground cable
is omitted or disconnected.
Protecting Against Electrostatic Discharge
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 chassis.
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, do not remove the component from
the antistatic packing material until you are ready to install the component in your system. Just before
unwrapping the antistatic packaging, be sure to discharge static electricity from your body.
2. When transporting a sensitive component, first place it in an antistatic container or packaging.
3. Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and workbench
pads and an antistatic grounding strap.
Battery Handling Reminder
CAUTION: Danger of explosion if battery is incorrectly replaced. Replace only with
the same or equivalent type recommended by the manufacturer. Discard used
batteries according to the manufacturer's instructions.
