FIPS SO & DO pwd forgotten

Hey Folks,

 

Need your inputs again :)

 

I have a HA FIPS pair 8900 device, one of the F5 got faulty and just got RMA'ed. But I'm not having the SO & DO pwd now. Also I'm unable to load the UCS because of it. What route should I follow now ? Should I reset a new set of SO & DO pwds on scheduled window ?
