Obrázek 66. Removing the system board
Kroky
1. Remove the eight screws (M1.6x5.5) that secure the right I/O-board and left I/O-board cable connectors to the system board.
POZNÁMKA:
When reinstalling the right I/O-board cable connectors, align the connector so that the side labeled 'MB' is
connected to the system board, and the side labeled DB-R is connected to the right I/O-board.
POZNÁMKA: When reinstalling the left I/O-board cable connectors, align the connector so that the side labeled 'MB' is
connected to the system board, and the side labeled DB-L is connected to the left I/O-board.
2. Remove the right I/O-board and left I/O-board cable connectors from the system board.
3. Remove the interposer boards from the right I/O-board, left I/O-board, and system board.
VÝSTRAHA:
Technicians must remove the interposer board immediately after removing the I/O board cable
connectors to prevent the board from falling out of the system during subsequent removal procedures.
POZNÁMKA: The pins on the interposer board are fragile. Avoid contact with the pins on the board, instead handle the board by
lifting and holding from the edges or the sides.
