Safety Instructions
WARNING: Working on systems that are still connected to a power supply can be
extremely dangerous.
CAUTION: System components and electronic circuit boards can be damaged by
discharge of static electricity.
CAUTION: Many repairs may only be done by a certified service technician.
You should only perform troubleshooting and simple repairs as authorized in
your product documentation, or as directed by the online or telephone service
and support team. Damage due to servicing that is not authorized by Dell is not
covered by your warranty. Read and follow the safety instructions that came
with the product.
To avoid injury to yourself or damage to your system, follow these guidelines:
• Always disconnect the system from the power outlet whenever you are
working inside the system case.
• If possible, wear a grounded wrist strap when you are working inside
the system case. Alternatively, discharge any static electricity by touching
the bare metal chassis of the system case, or the bare metal body of any
other grounded appliance.
• Hold electronic circuit boards by the edges only. Do not touch the
components on the board unless it is necessary to do so. Do not flex or
stress the circuit board.
• Leave all components inside the static-proof packaging until they are
ready for installation.
