Page 23: Cascade Theory Of Operation
CASCADE THEORY OF OPERATION The CASCADE product is capable of acting as an RF repeater or base station with up to two “Simultaneous Receive Channels” and up to two 125W “Simultaneous Transmit Channels”. The CASCADE product is comprised of the following: •... - Page 24 Cascade Theory of Operation The CASCADE system requires adequate ventilation and ALL vents must be kept clear. The cooling fans will only work when the front panel is properly in place. Cooling airflow moves from the front of the unit to the rear of the subrack so the airflow must not be restricted in any way.

94.5%. It delivers up to 2x16.7A output current with 48V output voltage and is capable of operating from -30°C to 60°C. See Figure 5 for images of the CASCADE power supply. The power supply is designed to provide sufficient power for a full CASCADE subrack containing two transceivers, two 125W power amplifiers, three fans and an option slot. -

48V. Mounted on the mainboard (DC-DC -48V to 48V Isolated PSU) these bricks are designed for telecommunication purposes and provide the isolation required for CASCADE operation. An auxiliary board (-48V to 13.8V Isolated AUX) is also attached to the mainboard providing a 13.8V output voltage for external use. - Page 29 The power supply’s logic is only used to report its state, including: voltages, currents and temperature to the other components of the CASCADE. The microcontroller receives input from different sections of the PSU and can activate LED lights in the front of the unit and transmit this information via the FIB.
