6.3.3.2 Bridge Board Interface (Backplane to Server Board)
The backplanes provide a pathway for the control panel, PCIe*, USB, and other miscellaneous
signals from the server board to connector interfaces on the backplane. The server board and
backplane have matching 120-pin connectors which are attached using a PCB called the Bridge
Board, as shown in the following figure. To assure the bridge board is held in place while the
integrated platform is shipped or installed into the rack, the bridge board is held in place using
metal clips which latch the bridge board to each of its connectors on the backplane and server
board.
