Perform the following steps to properly install the main rack within the site 
building: 

1  Measure the mounting location for the main rack within the row. 

2  Carefully mark the mounting holes with a pencil, as indicated on the 

appropriate main rack footprint. 

3  Drill the marked mounting holes to the appropriate depth of the mounting 

hardware with a hammer drill and bit. 

4  Insert an anchor into the drilled hole. 

If necessary, tap the anchor into place using a hammer. 

5  Remove the four screws securing the bottom kick panel to the front and back 

of the main rack. 

Remove the kick panel and set aside during installation. 

6  Carefully move the main rack into the position indicated by the holes in the 

floor. 

Adjust and level the main rack as necessary to align the rack mounting holes 
with the pre-drilled holes in the floor. 

7  Secure the main rack to the site floor with the locally procured mounting 

hardware. 

8  If required, connect adjacent cabinets to each other using ganging hardware. 

Auxiliary equipment for the main rack includes: 

• 

GPS antenna 

• 

Environmental alarm block 

• 

Mandatory alarms 

• 

Optional alarms 

• 

Surge arrestors 

• 

Grounding 

• 

Cable supports 

When locating the GPS antennas, install vertical mast (or antenna mount) at a 
location that provides a line of sight to as much of the horizon as possible. Solid 
buildings and overhanging trees will block the 1.575 GHz signal and cut down on 
the amount of sky visible and therefore the number of satellites the antenna can 
see. Satisfactory performance can be achieved with as much as 25 percent of
