2.0  Installation

2.1  Mechanical
The 1584-45 consists of one RF printed circuit board (PCB) housed in a 1 RU (1 3/4 inch high) by 12 inch 
deep chassis. Redundant, switching, +24 VDC power supplies with the DC output diode OR’d provide 
redundant power for the internal and external amplifiers and LEDs. Connectors are type F, female for the 
RF connections. The 1584-45 can be secured to a rack using the 4 holes on the front panel. Figure 
2.1.shows how the 1584-45 is assembled. J28, J27, J26, and J25 connect DC Power to the fuses as shown 
and J30 and J29 connect the DC voltage from the power supplies to the PCB as shown.
