2.2.2 Mounting Procedures
2.2.2.1 Introduction
The base stations/repeaters can be mounted in the selected cabinet or rack, and may be installed by
following the procedures below. However, the following three scenarios require special mounting
procedures:
• Customer plans to mount equipment in a rack or cabinet.
• Customer orders two base stations/repeaters in a single rack.
• Customer requires slide rail assembly.
2.2.2.2 Installing Racks
In a typical installation, the rack is bolted to a concrete floor to provide stability.
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.
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. After all debris is removed and cement dust is cleared away, remove whatever protective
covering has been placed on the equipment, including the antistatic bag.
2.2.2.3 Mounting Floor-Mount 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.
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.
