Safety Instructions
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 additional safety best practices
information, see the Regulatory Compliance Homepage at dell.com/
regulatory_compliance.
WARNING: Disconnect all power sources before opening the computer cover or
panels. After you finish working inside the computer, replace all covers, panels,
and screws before connecting to the power source.
CAUTION: To disconnect a network cable, first unplug the cable from your
computer and then unplug the cable from the network device.
CAUTION: To avoid damaging the computer, ensure that the work surface is flat
and clean.
CAUTION: To avoid damaging the components and cards, handle them by their
edges and avoid touching pins and contacts.
CAUTION: Only a certified service technician is authorized to remove the
computer cover and access any of the components inside the computer. See the
safety instructions for complete information about safety precautions, working
inside your computer, and protecting against electrostatic discharge.
CAUTION: Before touching anything inside your computer, ground yourself by
touching an unpainted metal surface, such as the metal at the back of the
computer. While you work, periodically touch an unpainted metal surface to
dissipate static electricity, which could harm internal components.
CAUTION: When you disconnect a cable, pull on its connector or on its pull-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 connectors and ports are
correctly oriented and aligned.
