AC450/Advant Controller Synchronization with AC800M Controller and CI855 Card
AC800+CI855 card will be used , what program we need to write in the AC800M ?
What changes we need to do in the Advant Controllers , as existing Unix station is acting as time master which will be demolished ?
What is not very documented is that the CI855 master role need to be protected by making absolute sure ALL OTHER MB300 nodes are muted in terms of adjusting or setting time, i.e. have their CLS1 element set to FALSE, 2, 0.
This may need to be revisited after software upgrades, etc. since 800xA for Advant Master tend to reset these settings after installing/upgrading. RTA Board Backup is required to make any change persistent across reboots.
To wake a "sleeping" CI855 clock master on MB300 (which may happen if any other MB300 node emit time adjust messages) either restart the CI855 or perform the following commands in OnLine Builder (target the CI855):
* SLTARG net,node
* RET CXAE000,10
