LWAYS FOLLOW THE STATIC-SENSITIVE EQUIPMENT HANDLING PROCEDURES ON
page 6-3 WHEN OPENING EQUIPMENT COVERS AND HANDLING PLUG-IN CIRCUIT CARDS.
CAUTION! SERVICE DISRUPTIONS WILL OCCUR IF THE ACTIVE CONTROLLER CARD
IS REMOVED WITHOUT AN OPERATIONAL STANDBY CONTROLLER. TO AVOID SERVICE
DISRUPTIONS, ALWAYS REPLACE THE STANDBY CONTROLLER FIRST. IN A PROTECTED
SYSTEM WITH TWO CONTROLLER CARDS, THE ACTIVE CONTROLLER SHOULD BE
SWITCHED TO STANDBY MODE BEFORE REMOVING. IN AN UNPROTECTED SYSTEM WITH
ONLY ONE CONTROLLER CARD, THE NEW CONTROLLER SHOULD BE INSTALLED AND
SWITCHED TO ACTIVE MODE BEFORE REMOVING THE OLD CONTROLLER.
S
ERVICE DISRUPTIONS MAY OCCUR IF TWO CONTROLLER CARDS ARE INSTALLED WITH
INCOMPATIBLE SOFTWARE, SUCH AS ONE DCS CARD AND ONE GR-303 CARD. NO
DISRUPTIONS WILL OCCUR UNTIL THE INCOMPATIBLE CARD IS SWITCHED INTO THE
ACTIVE MODE, ALLOWING TIME TO SAFELY REMOVE THE INCOMPATIBLE CARD. IF YOU
WISH TO INSTALL A CONTROLLER THAT IS NOT COMPATIBLE, VERIFY PROVISIONING
WITH OFFICE RECORDS, BOTH BEFORE AND AFTER INSTALLATION, TO ENSURE THAT NO
CIRCUITS HAVE BEEN ALTERED.
