Use the following safety guidelines to protect your computer from potential damage

and ensure your personal safety.

WARNING: Before working inside your computer, read the safety

information that shipped with your computer. For more safety best

practices, see the Regulatory Compliance home page at www.dell.com/

regulatory_compliance.

WARNING: Disconnect all power sources before opening the computer

See the safety instructions that shipped with the product or at

www.dell.com/regulatory_compliance.

CAUTION: Before touching anything inside your computer, ground yourself

by touching an unpainted metal surface, such as the metal at the back of

tab, not on the cable itself. Some cables have connectors with locking tabs

or thumb-screws that you must disengage before disconnecting the cable.

When disconnecting cables, keep them evenly aligned to avoid bending any

connector pins. When connecting cables, ensure that the ports and

connectors are correctly oriented and aligned.
