Patent ID: 8184450

Claim:
A modular packet network device comprising: a chassis having a power zone, a signaling zone, and a logic zone; and a first bus bar assembly to transfer a primary power from the power zone to the signaling zone and logic zone, the first bus bar assembly having first and second conductive members, each having a cross-section over a majority of its length with a minimum width-to-height ratio of 3:1 and at least one substantially flat side along the width direction, the at least one substantially flat side of the first conductive member facing the at least one substantially flat side of the second conductive member over a majority of the lengths of the first conductive member and the second conductive member, an electrically insulating layer interposed between the flat facing sides of the first conductive member and the second conductive member a power card connector coupled to the first and second conductive members and operable to couple to a power card on a first side of the first bus bar assembly; and a signaling card connector coupled to the first and second conductive members and operable to couple to a signaling card on a second side of the first bus bar assembly that is opposite the first side.
