Working with the Access Point Hinged Cover
To open the access point hinged cover, follow these steps:
Step 1 Use 0.5-in (13-mm) box-end wrench or socket set to unscrew and remove the four bolts on the front cover
of the unit. Only unscrew the hinge bolts about 2 turns until they are easily turned by hand, do not remove
the bolts on the hinge (Figure 3-10).
Step 2 The cover is hinged on the bottom. Carefully open the cover and remove the cover.
Note If the cover does not open easily, carefully loosen the hinge bolts again.

Closing the Access Point Hinged Cover
To close the access point cover, follow these steps:
Step 1 When closing the access point cover, be careful not to pinch internal wires.
Step 2 Carefully position the cover flush with all sides of the access point, then slowly hand-tighten each bolt.
Step 3 When all bolts are hand-tightened, use a 13-mm closed-end wrench or socket to partially tighten the bolts
in the tightening sequence shown in Figure 3-11. Tighten each bolt to 3 to 4 ft lbs (0.34 to 0.45 Nm).
Step 4 Repeat Step 3 using the same tightening sequence to fully tighten each bolt to 6 to 7 ft lbs
(0.68 to 0.79 Nm).
