BACKPLANE APPARATUS AND SWITCHING SYSTEM USING THE SAME

摘要

In a switching system using an N+1 switch redundancy method, a backplane connects a plurality of switch cards that are mounted in a half-slot of an upper end portion and a lower end portion of the center of a chassis and a plurality of line cards that are mounted in the half-slot of the upper end portion and the lower end portion of the chassis at both sides of the plurality of switch cards. In this case, in each line card and each switch card, a line card and a switch card of the same position are connected in the upper end portion or the lower end portion of the chassis using some connector groups, and a line card and a switch card that are disposed at the upper end portion or the lower end portion of the chassis are crossed and connected using the remaining connector groups.

主权项

1. A switching system using an N+1 switch redundancy method, comprising:
a chassis that comprises a plurality of half-slots and that is formed with an upper end portion and a lower end portion; a plurality of switch cards that are divided and mounted in a half-slot of the upper end portion and the lower end portion of the center of the chassis and that each form a connector group; a plurality of line cards that are divided and mounted at the half-slot of the upper end portion and the lower end portion of the chassis at both sides of the plurality of switch cards and that each form a connector group; and a backplane that connects a line card and a switch card of the same position in the upper end portion or the lower end portion of the chassis using a first connector group at each line card and each switch card and that crosses and connects a line card and a switch card of different positions in the upper end portion or the lower end portion of the chassis using a second connector group.
