15.7.1.2 Removing the system board
Ê Disconnect all cables from the system board.
Figure 269: Removing the system board
Ê Remove the 13 screws (see blue circles, orange circles show the centering
bolts) from the system board.
Ê Use both hands to lift the system board carefully out of the chassis in a slight
angle. Thereby you pull the connectors out of the I/O panel (see arrow).
V CAUTION!
Always take the system board with both hands!
Never lift the system board one-sided or at a heat sink, because the
solder connections between the socket and the system board come
under tension and increase the risk of damage and malfunction!
Do not damage the EMI springs which are essential to comply with
applicable EMC regulations and satisfy cooling requirements and fire
protection measures.
Ê Place the removed and the new system board on an antistatic surface.
