Macro Base Station Installation Procedures (NPM-1000)
Airflow
Each base station rack requires 0.6 m (2 feet) of open space in front of and behind it to allow suitable
airflow for cooling. Each cooling fan draws approximately 600 cubic feet per minute (CFM) of air.
Heat Output
Table 2.9 shows the amount of heat produced by a +24V base station.
Table 2.9 shows the amount of heat produced by a –48V base station.
Shock and Vibration
The base station uses network equipment-building system (NEBS2000) racks designed for use in level
4 seismic zones.
