Caution: Safety Instructions

Use the following safety guidelines to ensure your own personal safety and to help protect

your system f

rom potential damage.

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.

• 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.

6 PowerConnect System Information Guide

www.dell.com | support.dell.com

• 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:

– 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

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.

Caution: Safety Instructions (continued)

PowerConnect System Information Guide 7

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.

• 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.

Caution: Safety Instructions (continued)

8 PowerConnect System Information Guide

www.dell.com | support.dell.com

• 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.

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.

When Working Inside Your System

Protecting Against Electrostatic Discharge

NOTICE: Only a certified service technician should perform repairs on your system. Damage

due to servicing that is not authorized by Dell is not covered by your warranty.

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.

Regulatory Information

Electromagnetic Interference (EMI) is any signal or emission, radiated in

free space or conducted along power or signal leads, that endangers the

functioning of a radio navigation or other safety service or seriously

degrades, obstructs, or repeatedly interrupts a licensed radio

communications service. Radio communications services include but are

not limited to AM/FM commercial broadcast, television, cellular services,

radar, air-traffic control, pager, and Personal Communication Services

(PCS). These licensed services, along with unintentional radiators such as

digital devices, including computer systems, contribute to the

electromagnetic environment.

16 PowerConnect System Information Guide

www.dell.com | support.dell.com

Electromagnetic Compatibility (EMC) is the ability of items of electronic

equipment to function properly together in the electronic environment.

While this computer system has been designed and determined to be

compliant with regulatory agency limits for EMI, there is no guarantee that

interference will not occur in a particular installation. If this equipment

does cause interference with radio communications services, which can be

determined by turning the equipment off and on, you are encouraged to try

to correct the interference by one or more of the following measures:

• Reorient the receiving antenna.

• Relocate the computer with respect to the receiver.

• Move the computer away from the receiver.

• Plug the computer into a different outlet so that the computer and the

receiver are on different branch circuits.

If necessary, consult a Dell Technical Support representative or an

experienced radio/television technician for additional suggestions.

Dell computer systems are designed, tested, and classified for their

intended electromagnetic environment. These electromagnetic

environment classifications generally refer to the following harmonized

definitions:

• Class A is typically for business or industrial environments.

• Class B is typically for residential environments.

Information Technology Equipment (ITE), including peripherals,

expansion cards, printers, input/output (I/O) devices, monitors, and so on,

that are integrated into or connected to the system should match the

electromagnetic environment classification of the computer system.

A Notice About Shielded Signal Cables: Use only shielded cables for

connecting peripherals to any Dell device to reduce the possibility of

interference with radio communications services. Using shielded cables

ensures that you maintain the appropriate EMC classification for the

intended environment. For parallel printers, a cable is available from Dell.

If you prefer, you can order a cable from Dell on the World Wide Web at

accessories.us.dell.com/sna/category.asp?category_id=4117.
