To install the 8ESIDB daughter board:
1. Included with the ESIDB are two plastic spacers. Install the plastic spacers onto
the 8ESIU blade. Make sure to attach the spacers so that they extend out on the
side of the daughter board which has the CN2 connector.
2. Position the 8ESIDB’s CN1 connector over the CN2 connector on the ESIU blade.
Press the boards together, ensuring the plastic spacers lock in place.
3. Secure the boards together at the metal spacers by attaching the two metal
screws.
4. Install the ESIU blade into the slot.
