Installing the new system board
▶
Check the settings on the new system board, see "Onboard settings" on
page
585.
▶
Insert the system board by holding it at a slight angle. Slide the connectors
into the I/O panel, see Figure 336.
▶
Lower the system board carefully into the chassis.
▶
Adjust the system board. If necessary adjust the position of the system
board with a gentle twisting motion (orange circles in Figure 336 show the
centering bolts).
▶
Fasten the system board with the 13 screws, see Figure 336.
▶
For Japan / APAC / North America only:
Replace the CMOS battery installed on the new system board with a new
CMOS battery (see "CMOS battery" on page 474), because charging of
CMOS battery might be reduced during stocked in warehouse.
▶
Remove the heat sink with the CPU from the defective system board, see
"Removing the heat sink" on page 421.
▶
Remove the protective plastic cover from the CPU socket of the new system
board and fit the protective plastic cover onto the socket of the defective
system board, which will be sent back to spares.
Returned system boards without this cover probably have to be
scrapped.
▶
Install the heat sink with the CPU on the new system board, see "Installing
the CPU and heat sink" on page
413.
