Chapter 4: Base Station Installation Procedures
Prepare the Location
This procedure applies to installing the base station on a concrete floor and securing the racks using
4-inch concrete expansion bolts (called anchor bolts in this document). These anchor bolts are
designed for sites in level 4 seismic zones and may not be suitable for your site. See your field
engineering package for rack installation procedures specific to your site.
 To prepare the location
1 Mark with a chalk line the location where you will install the racks. Refer to your field engineering
package for the required location. If there are overhead requirements, use a plumb line to align the rack
vertically.
Placed together, the racks have a footprint of 1.2 m by 0.6 m (47 1/4 inches by 23 5/8 inches). The racks
are 2.11 m (83 inches) in height.
2 Verify that there is adequate space for the racks:
i Move both racks to the intended installation location.
ii Ensure that you have room for both racks, their cabling, and enough space for airflow and the
insertion and removal of components.
See page 22 for airflow requirements.
iii Remove the racks.
3 Place the isolation pad in the precise location designated for the first rack using the chalk line as your
guide.
The base of each rack hangs over the edge of its isolation pad by 1 mm (1/32 inch).
4 Trace the anchor hole locations on the concrete floor using the cutouts on the isolation pad as your
guide. Use the four outer locations and trace the entire shape of the anchor holes.
5 Remove the isolation pad.
6 Punch the concrete in the outer edge of each anchor guide using the concrete punch. This will make
drilling the anchor holes easier.
7 Drill an anchor hole 101 mm (4 inches) deep on the outer edge of each anchor hole using a hammer drill
with an 3/4-inch carbide-tipped masonry bit.
8 If the drill bit hits a metal reinforcement bar, move the hole location to the inner edge of the anchor guide
and repeat steps 6 and 7.
9 Ensure that the holes are 101 mm (4 inches) deep; otherwise, the anchor bolts will not sit properly.
10 Clean each anchor hole thoroughly using a vacuum cleaner with a narrow nozzle attachment that can
reach into the hole and remove the debris.
11 Cover the anchor holes with tape to prevent debris from entering them.
12 Repeat steps 3 to 11 for the second rack.
