Preparing to move the FRUs to new chassis.

1. Observe all ESD precautions.

Moving the MIC cards.

1. From the rear of the old chassis, loosen the MIC card's captive screws, one on each side of the face plate. A Phillips screw driver may be required to loosen the screw.

2. Pull the lock and ejector handles outward completely to release the card from the mid-plane chassis.

3. Slide the card out of its slot until it is completely removed from the chassis.

4. In the new chassis, insert the MIC card making sure that the lock and ejector handles are completely open and slide the card into the slot until it connects with the chassis mid-plane. Alignment pins located on the edge of the card should be aligned with the guide holes in the chassis. Use care not to bend any pins.

5. Push in the lock and ejector handles to secure the MIC card in place. The card face plate should be flush with the adjoining cards in the chassis.

6. Secure the card by tightening the captive screws on the card face plate.

7. Insert the corresponding removed PCMIC card into slot one (lower slot) until it is completely inserted.

   a) If the PCMIC card does not fit correctly, do not force it into the slot. Forcing the card may cause damage to the card or the slot. Remove the card from the slot and attempt to insert it again.
