Reinstall the System Board

Reinstall the System Board

1.  Make sure that the system-board latch handle is in the extended position.
2.  Align the system-board rails with the tracks on the  chassis and slide the board in until it is approximately  6 mm (0.25 in) from the riser-card edge connector.
3.  Rotate the latch handle counterclockwise until the the  system board is properly aligned with the riser-card edge connector.
4.  Continue rotating the latch handle counterclockwise  while firmly pushing on the system-board rail on the  right-hand side of the system board.
   Note:  Do not push on the microprocessor, the DIMMs, or the DIMM sockets to install  the system board.

    Make sure that the system board is fully seated in the  riser-card edge connector.

5.  Re-tighten the riser card mounting screw.
6.  Push down on the latch to lock the tab on the underside in the opening  (hole) in the chassis. This securely holds the latch in the closed position.
    
   Note:  You cannot see the connection with a full-sized adapter in place.  To make sure that the system board is fully seated, lock the tab on the  underside of the system-board latch in the opening (hole) in the chassis.
   
7.  If you want to install or remove any other options, do so now.  Otherwise, go to Completing the Installation.
