Safety precautions
For your protection, observe the following safety precautions when setting up your equipment:
●Follow all cautions, warnings, and instructions that are marked on the equipment.
●Never push objects of any kind through openings in the equipment. They could touch
dangerous voltage points or short out components. This could result in fire or electric
shock.
●Refer servicing of equipment to qualified personnel.
●To protect both yourself and the equipment, observe the following precautions.
Precaution Item Problem

System precautions
!WARNING:
!
WARNING: DO NOT make mechanical or electrical modifications to the computer. Dell
Computer Corp. is not responsible for regulatory compliance of modified
computers.
Ensure that the voltage and frequency of the power outlet used matches the electrical rating
labels on the equipment.
Wear antistatic wrist straps when handling any magnetic storage devices and printed circuit
boards.
Each power supply uses nominal input voltages of 100-240 V AC at 50-60 Hz. The computer
should be powered by an Uninterruptible Power Supply (UPS) or a non-switched,
dedicated, 20-amp circuit. Dell products are designed to work with single-phase power systems
having a grounded neutral conductor. To reduce the risk of electrical shock, do not plug Dell
products into another type of power source. Contact your facilities manager or qualified
electrician if you are unsure what type of power is supplied to your building.
A UPS provides a temporary electrical supply to a computer for several minutes, depending on
the number of components connected to the UPS. For a CMS computer, a 1.5KVA minimum is
required for each power supply. See your UPS documentation to determine the projected
amount of backup battery time for your model. If the system is without power for longer than the
backup time, the system may shut down improperly, and the customer could lose data.
Each of the following items requires a separate power cord:
●Computer
●External peripherals
●Monitor
Keep in mind the following:
●The room must have sufficient air conditioning capacity to support the cooling needs of the
entire system.
●The air conditioning system must have controls that prevent excessive temperature.

Unpacking and inventorying the equipment
!WARNING:
!
WARNING: Never move the computer when the power is on. Excessive movement can cause
catastrophic disk drive failure. Always power the system off before moving the
computer.
!WARNING:
!
WARNING: Always wear an electrostatic discharge (ESD) strap when handling internal
components.
CAUTION:
!
CAUTION: Always have up-to-date system backups before turning off and moving the
computer.
Inspect all shipping cartons for evidence of physical damage. If a shipping carton is damaged,
request that the carrier representative be present before the carton is opened.
Unpack the computer and associated peripheral equipment. Compare the contents of the carton
to the shipping inventory list to verify that all equipment was delivered.
