Secondary SUP is facing some Hw problem, had RMA the unit and would like to replace it.
But I have few question here:
1) Current SUPs and running IOS 12.2.(18)SXD6.
2) The RMA unit may running IOS other than 12.2(18)SXD6.
When I replace the secondary SUP, with new unit the software version definately will different.
Will it impact the redundacy ? Can I copy from primary to secondary unit the software ?
My concern if primary refuse to recognised the secondary Sup during bootup due to different software version, and put in on ROMMON, then I have problem to copy the software from primary SUP to secodary sup to make it identical software image at both Sup.
I remember there is document in cco about replacing the secondary sup, but now i cant find it.
