REMOVE AND/OR REPLACE CELLWORX CARDS

Summary: This procedure instructs the operator in the steps required to remove a defective AIC, SC, RIC, or EIM from the shelf and install a replacement card in its place. Before removing a card from the shelf, the user should verify there is no traffic on it by performing a switch over to the protect card if available.

1.Place the ESD wristband on your wrist and snap the ground wire to it. Plug the ground plug into the grounded ESD jack located at the upper right side of the STN shelf.

2.Locate the cards to be removed and their replacements.

3.To remove a card from the shelf, pry outward on the ejector ears using the thumbs. This will dislodge the card from the backplane and allow it to be withdrawn from the card guides. Refer to Figure 777-1 for an example of removing a card from the shelf. This can be applied to the front access or the rear access cards.

4.Using one hand to support the card underneath as it is drawn out, remove the card with the other hand.

5.Place the card in an Electro-statically protected bag and place in the proper packaging material in anticipation for its return to ADC Telecommunications for evaluation.

6.Align the replacement card with the card guides in the shelf at the proper slot position holding the card with the component side facing right. Refer to Figure 777-2.

7.Slide the card in until the ejector ears reach the card cage trough. Fully seat the card into the backplane by pressing the ejector ears toward the shelf until they rest against the faceplate or the printed circuit board for EIMs. Once seated, give the card a gentle push to ensure it makes good contact with the backplane.

Warning: Do not use excessive force. If excessive resistance is felt, remove the module, check for alignment and/or obstructions, and try seating it again. Take care not to bend any pins in the backplane.

8. After replacing the card, the user may perform some acceptance tests per NTP-011.

Stop! You have completed this procedure.
