•  If you need to disconnect cables from the system board assembly, disengage all latches or 
release tabs on cable connectors first. Failing to release the tab before removing the cables will 
damage the cable sockets on the system board assembly. Any damage to the cable sockets 
might require replacing the processor board or system I/O board.
•  The connectors on your system board assembly might look different from those in the 
illustration, but the removal procedure is the same.

2.  Disengage the connector from the cable socket.
