Reassembling the
Device
To reassemble the device:
o 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 force! Be sure the connectors
latch.
o Connect the ribbon-cable between the CPU board and the front panel. Be especially
careful not to bend any of the connector pins! Do not use force! Be sure the plug con-
nectors latch.
For a model with detached operator panel, first connect the ribbon-cable from the 68-
pin connector on the back of the device to the CPU board. Then attach connector X16
under the D-subminiature port on the CPU board. The X16–connector can be plugged
in either direction.
o Carefully replace the front panel being mindful of the ribbon-cables. Fasten the front
panel to the case with the screws.
o Replace the covers.
