Figure 158: Position of screws and stand-offs
▶ Remove the two stand-offs (see orange circles) from the system board.
▶ Remove the nine screws (see blue circles) from the system board.
▶ 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.
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.
▶ Place the removed and the new system board on an antistatic surface.
