3.5 Power Requirements
3.5.1 Power Supply Card Slot Details
The leftmost slot in the Expedio card cage (as viewed from the rear of the unit) is designated as
the “PRIMARY A” power supply. The main bus voltages (+5 and +/-12) are summed in the
backplane and provide the supply the plug-in modules.
NOTE:
The front panel LCD screen displays the system supply voltages and the
nomenclature follows the physical location of the power supply modules.
3.5.2 AC Line Voltage
The Expedio uses a high reliability, universal input switching power supply capable of operation
within an input range of:
100 - 240 VAC; 50/60 Hz
The power supply module is removable from the unit and a perforated cage protects service
personnel from high voltage. The power supply is fan cooled due to high power consumption by
the PA.
CAUTION
High voltage is present when the unit is plugged in. To prevent electrical shock, unplug the power
cable before servicing. Qualified personnel should service power supply module only.
