12.2.2.2
Installing Racks
In a typical installation, the rack is bolted to a concrete floor to provide stability.
Prerequisites:
The following procedure describes the steps necessary to bolt the rack to a concrete floor. Be sure to
check with local authorities to verify that the following procedure conforms to local building codes and
regulations before permanently installing the rack.
Procedure:
1 Carefully align the rack at the desired anchoring location.
2 Use the rack mounting foot as a template and mark the location of the six 19 mm (3/4 in)
diameter mounting holes. All six anchoring positions must be used.
3 Move the rack aside, drill holes in the concrete floor, and install the mounting anchors
(RAM RD-56 anchors recommended) per instructions provided with the anchors. Make sure that
none of the anchors comes in contact with the reinforcing wire mesh buried in the concrete; the
rack must be electrically isolated from any other equipment or materials at the site.
4 Align the rack with the installed anchors and lightly secure the rack to the floor using the proper
mounting hardware. Do not tighten the mounting hardware at this time.
5 Check the vertical plumb of the rack. Also check that the top is level. Use shims (flat washers or
flat aluminum plates) as necessary under the rack mounting foot to achieve vertical plumb and
horizontal level.
6 Tightly secure the rack to the floor anchors making sure that it remains vertically plumb and
horizontally level.
7 Assemble the two mounting brackets to each side of the repeater either in the front or middle of
the repeater depending on whether rack is made for front mount or mid-mount using three
supplied screws for each bracket.
8 Hold repeater in the desired rack location. Line up mounting bracket holes with mounting
locations on rack rail and assemble both brackets to the mounting rail on the rack using 10-32
screws.
CAUTION:
Cement dust from concrete flooring is harmful to electronic equipment and wiring. Make sure
that the rack and any collocated equipment are protected prior to drilling holes in the concrete
floor. Use a tarpaulin, cloth, or plastic sheeting to cover exposed equipment.
(The rack should be already covered with an antistatic bag; do not remove the bag at this time.)
Use a vacuum while drilling the holes to minimize the spread of concrete dust. Carefully clean
up any accumulated dust and debris from the anchor installation before uncovering the
equipment.
12.2.2.3
Installing Cabinets
Each cabinet bottom is pre-drilled with four (4) mounting holes to allow attachment to the site floor. If
installing on a concrete floor, use the cabinet as a template, mark the hole locations, and follow the
procedures above for anchoring equipment racks. If installing on a wooden floor, use lag bolts and
washers (customer supplied) to secure the cabinet to the floor.
