5.6.2 Replacing the Motherboard
This section includes the procedures required to replace the ColorPASS motherboard. Spare motherboards ship without memory, CPU, and the BIOS chip. The memory, CPU and BIOS chip from the old board will need to be installed on the replacement motherboard. a. To Replace the Motherboard 1. If you replaced the motherboard with a new board, replace the following components on the board: � Memory (see page 4-30) � CPU (see page 4-32) � BIOS chip (see page 4-34) 2. Angle the motherboard so the back panel connectors on the motherboard fit into the cutouts in the back of the tray. See F04-506-02 on page 4-27. 3. Align the mounting holes on the edge of the motherboard (opposite the back panel connectors) with the standoffs located in the base of the tray (see F04-506-02 on page 427). 4. Once the mounting holes in the motherboard are aligned over the standoffs, gently push the motherboard down to secure it to the tray. 5. Insert the 9 motherboard mounting screws to attach the motherboard to the tray but do not tighten them completely (see F04-506-01 on page 4-25 for screw locations). 6. Tighten the 9 motherboard mounting screws. Do not overtighten the screws; doing so could damage traces on the motherboard. b. To Replace Boards 1. Replace the following boards in the appropriate motherboard connectors: � UIB board in the connector labeled PCI1 � Display video board in the connector labeled AGP � Video board in the connector labeled PCI5 As you plug the board into the connector on the motherboard, make sure that the board connector is properly aligned with the connector on the motherboard. 2. Replace any option boards installed in remaining connectors on the motherboard.
