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.
T
O 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.
