Macro Base Station Installation Procedures (NPM-2500)
Physical Requirements
Before you begin installing the base station, read the following physical requirements. Ensure that each
requirement is met before proceeding with the installation, and consult your methods of procedures
(MOPs) for information concerning transportation method, route, and precise installation locatio
n.
Dimensions
Table 2.1 lists the dimensions of the individual base station components. The components are
designed to be rack-mounted on a 19-inch telecommunications chassis.
Torque Values
Table 2.2 shows the recommended torque values for the different sizes of fasteners used in the racks.
Unless otherwise specified, torque tolerances are ±0.2 N
•m (±1.8 inch-pounds).
Component Height and Depth Weight
Chassis 1U, 300 mm (11.8 inches) depth 4.8 kg (10.6 pounds)
PDP 1U 2 kg (4.4 pounds)
Radio module / shelf 6U (each shelf holds 4 radio modules) 11 kg (24.3 pounds) per module
Switch 1U 3.8
