1-2 Installing the pad
Site selection and preparation
You can install the Series 800A cabinet in any suitable location; however, you
should consider the acoustical noise level at the site and the surrounding
terrain.
Acoustical noise
Sites with vegetation and landscaping typically absorb more of the incremental
noise from the cabinet's equipment and environmental controls.
A hard site is defined as a cabinet or pad installation on a paved concrete
surface such as a roadway or parking lot. Grass, trees and bushes typically
render lower noise readings than those for a hard site.
Table 1-1 shows the acoustical noise specifications for the S800A cabinet at a
hard site installation.

Pad preparation
Nortel Networks recommends that you mount the S800A on a concrete pad.
Locate the pad above local flood plains to minimize the likelihood of damage
from adverse traffic and environmental conditions.
Consider the following items when preparing the site for the pad:
•
•
•
AccessNode 323-3001-210 Issue 1.0
soil conditions suitable to support the weight of the cabinet and concrete
pad (reference local building codes)
commercial power service availability to provide the ac power input for the
S800A cabinet as shown in Chapter 3, "Connecting commercial power" in
this practice
