Included with the 8SLIDB are three plastic spacers and two metal spacers. The plastic spacers
are installed diagonally across the daughter board. The metal spacers are then installed in the
remaining two corners. The metal spacers are each secured by a screw, securing the two
boards together. Make sure to attach the spacers on the front of the daughter board so when
installed, the components are facing the 8SLIU PCB.
Position the 8SLIDB's CN1 connector over the CN9 connector on the 8SLIU PCB. Press the
boards together, ensuring the plastic spacers lock in place.
Install the screws for the metal spacers.
Install the 8SLIU PCB into the slot.
Note that the white PCB Pull Tab should always be positioned closest to the top of the
cabinet.
Set the 8SLIU's run/block switch to block, UP .
The 8ESIU with an 8SLIDB installed will use the first block of 16 extension ports available.
Confirm the ports used with Program 10-03
