3.1 Rear Panel Connections
3.1.1. Power Supply Slot
The leftmost slot in the SL9003Q card cage (as viewed from the rear of the unit) is
designated as the “PRIMARY A” power supply. This slot always contains a power
supply.
The next slot to the right is designated as “SECONDARY B”. This slot will be occupied
only if a high-power amplifier option is installed, or a redundant power supply option is
installed. The SL9003Q TX utilizes these slots to separate the PA supply lines for the
HPA option.
NOTE:
The front panel LCD screen displays the system supply voltages and the
nomenclature follows the physical location of the power supply modules.
3.1.2. AC Power Supply
The SL9003Q TX and RX both use a high reliability, universal input switching power
supply capable. The power supply module is removable from the unit and a cage
protects service personnel from high voltage. The power supply is fan cooled to increase
reliability. The module supplies +12 V, +5 V, and +10 V for the PA (TX).
