Radio module
The Radio Module (Figure 5-2) for three sectors is contained in the ipBTS C30 RN chassis.
The Radio Module main functions are:
• Modulation of the RF signal provided by the ADCC (I/Q baseband signals), amplification
and emission.
• Two-way diversity reception and amplification of the RF signal, demodulation to I/Q
baseband signals and provided to the ADCC.

Fan trays
The ipBTS contains two redundant cooling fan trays which are part of the RN chassis
assembly. Fay trays are field replaceable. A fan cover (shown in Figure 5-3) protects the front
of the fan tray assembly and can be removed to replace a fan by loosening the captive screws.
See Module locking latch detail on page B-3 for replacement instructions.
