Precautions

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

NOTE: This procedure provides steps for replacing one or both Controller cards by physically removing the old card and installing a new card. In a redundant system, the standby Controller card can be replaced without disrupting service. The new Controller must be given two minutes to reboot and copy system settings from the old card. Then a CLI command is used to switch the standby Controller to active mode, so the other card (now in standby) can also be replaced.

NOTE: Alarm and Log Events – During the replacement process, if two Controller cards are installed with incompatible software, the Access Navigator will produce a minor alarm and the event log will contain an entry stating that one of the Controllers is Incompatible. This message is normal and can be ignored if the final installation provides two Controller cards with identical or compatible software.
