Action
If you have not done so during site preparation, drill holes to accommodate
the anchors. Use a roto hammer drill and a masonry drill bit to drill the holes.
Wear safety goggles when you drill the holes.
To properly stabilize a cabinet, you must anchor at least two diagonal
corners of the cabinet. For increased safety, anchor all four corners.
Clean each anchor hole thoroughly using a vacuum cleaner. If you are not
securing the cabinet immediately, cover the holes with tape to prevent them
from being filled with debris.
For each anchor, tap the anchor into the drilled anchor hole until it is flush
with the floor. Insert the threaded rod into the anchor and put the nut on the
bolt. Use a socket wrench to fully insert the threaded rod into the anchor.
Turn the rod until you are sure the anchor is secure in the hole.
Remove the nut and threaded rod from the anchor.
Remove the cooling unit from the bottom of the device. See the procedure
Removing the cooling unit from a Multiservice Switch 7480 (page
Remove the large grille in the base of the cabinet (4 nuts) using a wrench.
Carefully slide the cabinet into position.
Use a spirit level, or a plumb bob attached to the top of the frame, to ensure
that the cabinet is vertically aligned. Ensure that the cabinet is vertically
aligned side-to-side and front-to-rear within 0.25 cm (0.1 inch) of the overall
height.
If necessary, tilt the cabinet and adjust the levelling feet at the base of the
cabinet. Turn a levelling foot clockwise to lower the cabinet and
counterclockwise to raise the cabinet.
Assemble the bolt-down bracket using the upper and lower bolt-down
brackets as shown in Multiservice Switch cabinet anchoring (concrete and
raised floors) (page 324). The upper bolt-down bracket is shipped with the
cabinet. The lower bolt-down bracket is part of the anchoring kit.
Place the 1/4-inch hex-head screw through the holes in the upper and lower
bolt-down brackets. Make sure that the head of the screw is on the side of
the upper bolt-down bracket. Place the 3/4-inch brass washer and 1/4-inch
nut with the nylon insert on the screw. Do not tighten the screw completely.
Rotate the upper bolt-down bracket to face the hole with the anchor in it.
