To secure the racks
1 Ensure that the racks are correctly positioned and vertically aligned.
2 Connect the racks together using the junction bar and two 15/16-inch bolts. If you have trouble inserting
the bolts, ensure that the racks are level and located immediately adjacent to each other.
3 If you are securing the racks to the ceiling, consult your MOPs for instructions. Each rack contains four
5/8-inch bolt holes, one on each corner at the top of the rack. These bolt holes may be used to secure the
top of the rack.
4 Secure the racks to the floor. If you are using anchor bolts, complete the following steps:
i Remove any cables attached to the back of the lower cooling unit.
ii Unscrew the 5/16-inch screws holding the lower cooling unit to the rack.
iii Slide out the lower cooling unit.
iv Remove the front grill.
The front grill is attached to the frame using two half-turn screws. The screws are vertical when open
and horizontal when locked.
v Ensure that the parts in the anchor bolt assemblies are not loose.
vi Ensure that the anchor bolt, spacer sleeve, expansion sleeve, and expansion cone do not have any
slack. If any of these parts are loose, tighten the parts by hand to remove any slack. Do not start
spreading the expansion sleeve.
vii Place a hold-down plate over the holes in the base of each rack.
viii Loosely insert the anchor bolts through the hold-down plates into the base of the rack and the
anchor holes. If necessary, tap the top of each anchor bolt to ensure it is fully seated.
