CI840 Station Warning
One of our Client has a 800xA System with 5.1 Rev D Version commisioned around 8-9 Years back.
Recently they had ordered for some Spare Ci840 Modules. And CI840 spare modules with FW. Ver CI840 SW 4.3/1.
But when tested along with a already running CI840 at plant (Pair of Old CI840+ Newly supplied) its seen working well, without any faults during switching over from and redundacy and dual working fine. But a station warning with extended status (16#2020000) was observed in CBM Slave hwstatus. This is observed whenever the Old CI840 is in Prim Only , not during New CI840 is in Prim.
What could be the issue with this?
