2. Open the static-protective package and grasp the card by the edges and remove it from the package.
Set the card down on the static-protective package.
3. Remove the hex nuts from the RS-232 connectors and set them aside for future use.
4. Position the tray on a flat work surface.
5. Orient the logic card
A
(Figure 11 on page 34) so the connectors are facing the holes in the
faceplate.
6. Lower the front edge of the card into position on the tray just behind the faceplate.
7. Push the front edge of the card toward the faceplate, ensuring the two ESD tabs
B
(Figure 11 on
page 34) pass over the top of the USB connector housing.
Note: There are two ESD tabs on the back of the face plate that must on top of the USB connectors
housing when the logic card is installed. If the two tabs are not on top of the connector
housing, remove the card and reinstall it.
