Both jumpers must always be set for the same position.

To reassemble
the device:
o Carefully insert the boards into the case. The installation locations of the boards are
shown in Figure 8-4. For the model of the device designed for surface-mounting, use
the metal lever to insert the CPU board. The installation is easier with the lever.

on the back panel of the device. This task is not necessary if the device is for surface-
mounting.
o By first attaching to the I/O board, connect the ribbon cable between the I/O board and
the CPU board. Be especially careful not to bend any of the connector pins! Do not
use any force! Be sure that the plug connectors latch.
o Connect the ribbon cable between the CPU board and the front cover. Be especially
