General safety
WARNING: Observe the following instructions to help prevent potential for property damage,
personal injury, or death:
• The power supplies in your system may produce high voltages and energy hazards. Opening or
removing covers that are marked with the triangle symbol with a lightning bolt may expose you to
a risk of electric shock. Components inside these compartments should be serviced only by a
trained service technician.
•The system may have more than one power supply cable. To reduce the risk of electrical
shock, a trained service technician may need to disconnect all power supply cables before
servicing the system.
• You may find the following symbols on your rating label on your Dell product:

vii
• Do not operate your equipment with any cover(s) removed.
• The internal components, including memory modules, can become extremely hot during operation.
Allow sufficient time to cool before handling.
• Do not use damaged equipment, including exposed, frayed, or damaged power cords.
• When connecting or disconnecting power to hot-pluggable power supplies:
– Install the power supply before connecting the power cable to the power supply.
– Unplug the power cable before removing the power supply.
– Disconnect all sources of power from the system by unplugging all power cables from the power
supplies.
• Do not use the equipment where it can get wet. Protect equipment from liquid intrusion. If your
equipment gets wet, disconnect power to the equipment and to any attached devices. If the computer
is connected to an electrical outlet, turn off the AC power at the circuit breaker before attempting to
remove the power cables from the electrical outlet. Disconnect any attached devices.
• Do not push any objects into the air vents or openings of the equipment. Doing so can cause fire or
electric shock.
• To prevent risk of exposure to laser, do not disable or open any Optical Disk Drives (ODD), such as a
CD-ROM, CDR/W, DVD drive assembly.
CAUTION: Observe the following instructions to help prevent damage to hardware or loss of data:
• Do not attempt to service the equipment yourself, except as explained in your documentation or in
instructions otherwise provided to you by Dell. Always follow installation and service instructions
closely.
• If your hardware has a voltage selection switch on the power supply, be sure to set it for the voltage that
most closely matches the AC power available at your location.

viii
• Operate the equipment only from the type of external power source indicated on the electrical ratings
label.
• To avoid possible damage to the system board, wait 30 seconds after turning off the equipment before
removing a component from the system board or disconnecting a peripheral device from the
equipment.
• For non-rack-mounted servers, leave 102 mm (4 in) minimum of clearance on all vented sides of the
equipment to permit the airflow required for proper ventilation. Restricting airflow can damage the
equipment or cause overheating.
• Do not stack equipment or place equipment so close together that it is subject to re-circulated or
preheated air, such as next to an appliance or exhaust vent.
• Ensure that nothing rests on your equipment's cables.
• Move equipment with care; ensure that all casters and/or stabilizers are firmly connected to the system.
Avoid sudden stops and uneven surfaces.
• Review the weight limits referenced in your equipment documentation before placing a monitor or
other device on top of your equipment.
• Use only approved power cable(s) rated for the equipment. The voltage and current rating of the cable
should be greater than the ratings marked on the equipment.
• Plug the equipment power cables into properly grounded electrical outlets. 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. Ensure that the total ampere rating of all equipment
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 the equipment from fluctuations in electrical power, use a surge suppressor, line
conditioner, or uninterruptible power supply (UPS).
WARNING: Incorrectly installing a battery or using an incompatible battery may increase the risk of fire
or explosion. Replace the battery only with the same or equivalent type.
• Do not disassemble, crush, or puncture batteries.
• Do not store or place your battery pack next to or in a heat source such as a fire, heat generating
appliance, car or exhaust vent. Heating battery cells to temperatures above 65 °C (149 °F) can cause
explosion or fire.
• Do not attempt to open or service batteries. Do not dispose of batteries in a fire or with household
waste. For more details, see Battery Disposal instructions.
WARNING: Additional Instructions for Rack-Mounted Systems

ix
CAUTION: If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack
environment may be greater than room ambient. Therefore, consideration should be given to installing the
equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the
manufacturer. For more information, see your product documentation.
• Your rack kit has been approved only for the rack cabinet provided. It is your responsibility to ensure
that installation of the equipment into any other rack complies with all applicable standards. Dell
disclaims all liability and warranties with respect to combinations of equipment with any other rack.
• Before installing your equipment in a rack, install all front and side stabilizers. Failure to install
stabilizers can allow the rack to tip over.
• Always load from the bottom up, and load the heaviest items first.
• Do not overload the AC power supply branch circuit that provides power to the rack.
• Do not stand or step on any components in the rack.
WARNING: Slide/rail mounted equipment is not to be used as a shelf or work space
• Before working on the rack, ensure 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.
• After installing equipment/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.
Do not add weight to slide or rail-mounted equipment.
The GS Mark indicates the product was tested and complies with the minimum
requirements of the German Product Safety Act (a.k.a. ProdSG).
The following statement applies only to rack-installed products that are GS-Marked:
This equipment is not intended for use at workplaces with visual display units, in
accordance with §2 of the German ordinance for workplaces with visual display units.
WARNING: For equipment using–(48–60) V DC power supplies, a qualified electrician must perform all
connections to DC power and to safety grounds. Do not attempt connecting to DC power or installing
grounds yourself. All electrical wiring must comply with applicable local or national codes and
practices.

Instructions for qualified electricians only:
Systems using –(48–60) V DC Power Supplies are intended for restricted access locations in accordance
with Articles 110-5, 110-6, 110-11, 110-14, and 110-17 of the National Electrical Code, American
National Standards Institute (ANSI)/National Fire Protection Association (NFPA) 70.
Before connecting safety ground or power cables, ensure that the power is removed from the DC circuit.
To ensure that the power is off, locate the circuit breaker on the DC source circuit (usually at the power
distribution of the battery distribution fuse bay). Switch the circuit breaker to the off position and, if
available, install an approved safety locking device on the circuit breaker or switch.
While grounding techniques may vary, a positive connection to a safety (earth) ground is a requirement.
When installing the unit, the ground connection must always be made first and disconnected last to
prevent a hazard.
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.
