When the cms was booted after the power outage, init read the S99route file that has a special route ( route add host switch1 r3amefl_1 -ifp bge1 ) that sends the switch traffic to bge1. But as the switch(PBX) was configured for bge0, the link traffic could not be sent
(r3amefl)-(root2)=# netstat -nr

Traffic from cm (x.x.x.202) is trying to send data to bge0 (x.x.x.209). but the cms has a route that says send all traffic from (x.x.x.202) to (x.x.x.210) but it can't. CM is configured to send to that through (x.x.x.209)
