Dell Mini Tower System manual Removing the Computer Cover, Replacing the Computer Cover

Unpacking Your Hardware Option

When you remove an option from its shipping carton, you may find it wrapped in antistatic packing material designed to protect it from electrostatic damage. Do not remove the packing material until you are ready to install the option.

CAUTION: See “Protecting Against Electrostatic Discharge” in the safety instructions at the front of this guide.

Replacing the Computer Cover

Use the following procedure to replace the computer cover:

1.Check all cable connections, especially those that might have come loose during your work. Fold cables out of the way so that they do not catch on the computer cover. Make sure cables are not routed over the drive cage—they will prevent the cover from closing properly.

2.Check to see that no tools or extra parts (includ- ing screws) are left inside the computer’s chassis.
