Replacing the System Board
Replacement Routines
V
CAUTION!
Processors are components which are extremely sensitive to electro-
static discharges and must be handled with caution. After taking a
processor out of its protective wrapper, set it on an insulated antistatic
surface with the smooth side down. Never slide a processor over a
surface.
Ê
Open the locking lever and remove the processor (for description see the
Technical Manual for the system board D1859) and store it savely to avoid
any damage.
Ê
Remove the memory modules (for description see the Technical Manual for
the system board D1859).
Ê
Remove the retaining plate on the lower surface of the system board in a
secure way to be able to use it for the new board. Do not destroy the system
board!
V
CAUTION!
Do not use any tooling between the retaining plate and the system
board to separate the two parts. This would destroy the system board.
Figure 23: Removing the retaining plate
Ê
Use a pin from the component side of the board to press onto the threaded
bolts of the retaining plate and press the plate away from the board. Remove
the plate (figure 23).
The easiest way is to use a ballpoint or a little screwdriver which is larger
than the diameter of the bolt’s winding but nor larger than the hole in the
board.
