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: 
Only a certified service technician is authorized to remove 
the computer cover and access any of the components inside the 
computer.
 
CAUTION: 
To avoid damaging the computer, ensure that the work 
surface is flat and clean.
 
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.
 
CAUTION: 
To disconnect a network cable, first unplug the cable from 
your computer and then unplug the cable from the network device.
 
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: 
To avoid damaging the components and cards, handle 
them by their edges and avoid touching pins and contacts.
