MCPN750A Connector J4

Connector J4 is installed on both the processor board and the transition module for mechanical alignment purposes only. The keying tabs in the Type A connector assist with alignment of pins in the backplane connector during insertion of the boards. No signals are connected to the J4 pins except the ground pins 1 through 11 in Row F of the outer shield, which are connected to the board logic ground.
