(unlocked) position (you might have to first remove any adapters that might be
in the way). Press down on the bottom tab of the front adapter-retention
bracket to release it (the tab is inside the fan compartment that is next to the
front adapter-retention bracket). If you are installing a smaller adapter, rotate
only the rear adapter-retention bracket.

slot cover. Grasp it and pull it out of the expansion slot. Store it in a safe place
for future use.
Attention: Expansion-slot covers must be installed on all empty slots. This
maintains the electronic emissions standards of the computer and ensures
proper ventilation of computer components.
7. Follow the instructions that come with the adapter to set jumpers or switches, if
any.
Attention: Avoid touching the components and gold-edge connectors on the
adapter.
8. If you are installing a full-length adapter, remove the blue adapter guide (if any)
from the end of the adapter.
