factory wired (via the FC1 cable) to support sharing and redundancy. In main and
expansion cabinets with 2 peripheral shelves, the power supply slots of both peripheral
shelves are wired for shared RPS operation. In main cabinets with 3 peripheral
shelves, the lower two peripheral shelves are wired for shared RPS operation, while
the top peripheral shelf stands alone. In expansion cabinets with 4 peripheral shelves,
the first and second peripheral shelves are wired together for a shared RPS; and the
third and fourth peripheral shelves are wired together for a shared RPS operation.

frequency selection is made from the front panel.
The RPS front panel contains test points for measuring the voltage output. The output
is voltage adjustable via a potentiometer, and frequency select via a sliding switch.
Two panel mounted fuses protect the RPS circuitry from current overload. F1 protects
the oscillator and power amplifier circuitry, while F2 limits the BRV output current
superimposed on –48VDC to the peripheral card slots. The green power indicator
illuminates if input power is applied to the oscillator and power amplifier.
The power ON/OFF switch controls the voltage output from the power supply unit.
Switching one RPS to OFF does not remove power from the peripheral shelf if a shared
RPS is switched ON. Shared power supplies must both be turned off to remove all
power from both shelves.
