If you do not replace the card or install another add-in card, install a
slot cover over the vacant slot at the rear of the chassis (see
“Covering
an Open I/O Slot” on page 42).
6 Replace the side panel (see “Replacing the Side Panel” on page 27).
!
Hold the add-in card by its edges and do not touch any components or
contacts on the card. Static electricity in your body may damage
sensitive components on the card. As a precaution, touch any exposed
metal part on the metal chassis (preferably the metal part on the power
supply) before handling an add-in card to discharge any static electricity
in your body.
