Precautions

CAUTION! THIS PROCEDURE APPLIES ONLY TO ACCESS NAVIGATORS WITH ONE UNPROTECTED CONTROLLER CARD. DO NOT USE THIS PROCEDURE FOR PROTECTED SYSTEMS WITH TWO (REDUNDANT) CONTROLLER CARDS.

TO AVOID SERVICE DISRUPTIONS, DO NOT REMOVE THE ACTIVE CONTROLLER CARD. IF POSSIBLE, INSERT A NEW CONTROLLER CARD AND PUT OLD CONTROLLER CARD IN STANDBY MODE BEFORE REMOVING.

NOTE: This procedure provides steps for replacing a Controller card by installing a new Controller card and then removing the old Controller card. Because the Access Navigator has two card slots for holding Controller cards, a Controller card be replaced without disrupting service. First, the new Controller card is inserted into the empty card slot. The new Controller is given two minutes to reboot and copy system settings from the old card. Then a CLI command is used to switch the old Controller to standby so it can be removed.
