your system f

General

• 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.
Components inside these compartments should be serviced only by a trained service
technician.

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

• 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.

instructions.

• 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.

Safety Instructions 5

Caution:

• 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.

• 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:

Safety
Instructions

– 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.

Rack Mounting of Systems

6 Safety Instructions

Caution:

Safety
Instructions

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.

NOTE: Your system is safety-certified as a free-standing unit and as a component for use

in a Dell rack cabinet using the customer rack kit. The installation of your system and rack
kit in any other rack cabinet has not been approved by any safety agencies. It is your
responsibility to have the final combination of system and rack kit in a rack cabinet
evaluated for suitability by a certified safety agency. Dell disclaims all liability and
warranties in connection with such combinations.

• System rack kits are intended to be installed in a rack by trained service technicians. If
you install the kit in any other rack, be sure that the rack meets the specifications of a
Dell rack.

CAUTION: Do not move racks by yourself. Due to the height and weight of the

rack, a minimum of two people should accomplish this task.

• 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.

• 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.

Safety Instructions 7

Caution:

• 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

www.dell.com | support.dell.com

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.

CAUTION: 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.

Safety
Instructions

Modems, Telecommunications, or Local Area Network Options

• Do not connect or use a modem during a lightning storm. There may be a risk of
electrical shock from lightning.

• Never connect or use a modem in a wet environment.

• Do not plug a modem or telephone cable into the network interface controller (NIC)
receptacle.

• Disconnect the modem cable before opening a product enclosure, touching or
installing internal components, or touching an uninsulated modem cable or jack.

Instructions

When Working Inside Your System

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):

• 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.

• When transporting a sensitive component, first place it in an antistatic container or
packaging.

• Handle all sensitive components in a static-safe area. If possible, use antistatic floor
pads and workbench pads and an antistatic grounding strap.

NOTE: Your system may also include circuit cards or other components that contain
batteries. These batteries must also be disposed of in a battery deposit site. For
information about such batteries, refer to the documentation for the specific card or
component.
