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
www.dell.com | support.dell.com
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.
6 PowerConnect System Information Guide
Caution: Safety Instructions (continued)
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.
PowerConnect System Information Guide 7
Caution: Safety Instructions (continued)
• 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
www.dell.com | support.dell.com
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.
8 PowerConnect System Information Guide
Caution: Safety Instructions (continued)
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.
