Update Controller Card Software

Precautions

Precautions

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

BEFORE DOWNLOADING NEW SOFTWARE, ALWAYS MAKE A BACKUP OF THE CURRENT CONFIGURATION SETTINGS TO PROTECT AGAINST ACCIDENTAL ERASURE. FOLLOW THE INSTRUCTIONS PROVIDED TO UPLOAD (SAVE) THE CONFIGURATION AND, IF NECESSARY, TO LOAD (DOWNLOAD) THOSE SETTINGS TO RESTORE THE ORIGINAL CONFIGURATION.

BOTH CONTROLLER CARDS MUST BE UPDATED TO THE SAME VERSION TO PREVENT SERVICE DISRUPTIONS RESULTING FROM INCOMPATIBLE DATABASE FORMATS. DO NOT MAKE ANY PROVISIONING CHANGES WITH MISMATCHED CONTROLLERS.

DO NOT UPDATE THE ACTIVE CONTROLLER CARD. UPDATING SOFTWARE IN THE ACTIVE CONTROLLER CARD WILL DISRUPT SERVICE. ALL EXISTING CROSS-CONNECTS WILL BE RESET. THE REDUNDANT CONTROLLER WILL NOT BECOME ACTIVE. NORMAL OPERATION WILL NOT RESUME UNTIL THE UPDATE PROCESS IS COMPLETE.

SERVICE DISRUPTIONS MAY OCCUR IF THE SOFTWARE UPDATE ALTERS THE MAJOR FUNCTIONS OF THE CONTROLLER CARD, SUCH AS ADDING GR-303FEATURES TO A DCS CARD. AFTER PERFORMING ANY MAJOR UPDATE, IT IS RECOMMENDED THAT THE PROVISIONING OF ALL CIRCUITS BE VERIFIED.

CONTROLLER CARD SOFTWARE VERSIONS 1.20 AND HIGHER REQUIRE THAT A SIMM (MEMORY MODULE) BE INSTALLED FOR OPERATION. ATTEMPTING TO UPDATE THE SOFTWARE BEFORE A SIMM IS INSTALLED WILL DISRUPT SERVICE. SEE INSTALL SIMM ON CONTROLLER CARD ON page 16-28.
