Bracing against earthquakes
You need a backboard that is large enough to hold all of the
components that you will install on the wall. To determine the
backboard size, refer to the wall plan that you developed using the
guidelines in Communication Server 1000M and Meridian 1 Small
System Planning and Engineering (NN43011-220). If you have not
developed a wall plan, please develop one now.
When you have determined the required backboard size, make sure
the measurements are within the limits listed in
Table 15

Determine fastener requirements.
You need the following information to determine fastener
requirements:
•
What fasteners you must use.
•
How deeply you must embed the fasteners into the wall.
•
The vertical distance between fasteners.
•
The horizontal distance between fasteners. For wood and metal
stud walls, determine this spacing by the spacing between wall
studs. Wall stud spacing must be within the range listed in
.
•
The required wall stud sizes for wood and metal stud walls.
