Abstract
A power supply module (100) for use with a card cage (10) for conditioning card cage input power and transmitting DC power to a backplane (20) of the card cage. The module (100) is adapted to be inserted into a card-receiving region (14) of the card cage from the front, and is removable therefrom. Connectors (70) on the leading edge (66) of the circuit card (102) of the module (100) self-engage with complementary connectors (30) of the backplane to establish power and signal connections therewith upon full insertion of the power supply module into a power module site (34) of the card-receiving region (14). The power supply module includes remote operator shut-off capability, overvoltage protection, overcurrent protection, overtemperature protection, temperature and voltage monitoring, and provides for orderly powering-up and powering-down of the card cage and for initializing critical data storage in the event of power failure. Either the power supply module (100) or card cage (10) provides rectification of AC power input to DC power. The module (100) is adapted to be air cooled by the cooling system for the card-receiving region, defined by a pluggable cooling module (50) with air…
