5.6 Removing and Replacing the BA440 Backplane
5.6.3 Install a New Backplane into the BA440 Enclosure
To install a new backplane in the BA440 enclosure:
1. Open the new backplane bag (make sure the static wrist strap is connected
to the system chassis).
2. Make sure all connector locking brackets are closed before installing the
new backplane in the chassis.
3. Align the new backplane assembly with the rear holes of the enclosure.
Insert the two bottom screws (left side first) and then the top screw (left) to
align the backplane against the card cage. See Figure 5–7.
4. Install the three nuts to the middle studs. Tighten the nuts down (3-inch
pounds torque).
5. Install the rear panel with the screws that were previously removed.
6. Remove the static clip from the rear frame and clip it to the front of the
enclosure.
