o At one end, disconnect the ribbon-cable between the front cover and the CPU board
(å). To disconnect the cable, push up the top latch of the plug connector and push
down the bottom latch of the plug connector. Carefully set aside the front cover.
o Disconnect the ribbon-cables between the CPU board (å) and the I/O boards (ê).
o Remove the boards and set them on the grounded mat to protect them from ESD dam-
age. A greater effort is required to withdraw the CPU board, especially in versions of
the device for surface-mounting, because of the communication connectors.
o Check the jumpers according to Figures 8-9 to 8-12. Change or remove the jumpers
as necessary.

Caution!
Electrostatic discharges through the connections of the components, wiring, plugs,
