Abstract:
A computer system including a circuit board, said system comprising:a slot coupled to a front side of said circuit board; a plurality of connectors affixed to said circuit board in alignment with said slot, said plurality of connectors including a first connector; a plurality of connector-pins extended in a direction substantially perpendicular to and away from said circuit board, and having a column and row arrangement within said connectors, said first connector including first and second connector-pins among said plurality of connector-pins; a register having an input line and an output line, said input line connected to a voltage source through a pull-up resistor, said first connector-pin connected to said input line of said register; and a circuit having an input terminal and connected to said first connector-pin through said register, said register connected to said input terminal of said circuit via said output line of said register, wherein depending on a voltage level of said first connector-pin, said register transmits one of a high and low signal to said input terminal of said circuit, said circuit detects a presence of a front card in said slot based on said one of high and low signal; wherein said circuit is at least one of a hot swap controller, a CPU, and a status indicator and wherein said hot swap controller is connected to said second connector-pin via a signal line, said hot swap controller adapted to distinguish between the insertion of a hot swappable front card and a non-hot swappable front card depending on said one of high and low signal and a voltage level of said second connector-pin.
