<p>Apparatus of facilitating circuit card replacement without down time, comprising a redundancy connector assembly (15-18) having a first connector and a second connector, a redundant bus (38), and a first circuit card coupled to the first connector of the redundancy connector assembly. The first circuit card has a logic circuit and a switch operable to selectively couple and decouple the logic circuit to one of the first connector and the redundant bus. A second circuit card also has a logic circuit and a switch operable to selectively couple and decouple the logic circuit to the redundant bus. A bypass cable (76) is used to couple the second connector of the redundancy connector assembly to the second circuit card during replacement of the first circuit card and routing signals destined for the first circuit card to the second circuit card.</p> |
