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will dislodge the card from the backplane and allow it to be withdrawn from the card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.
