Dear experts,
I got problem with ASR9010 that include RSP4G.
I tried to insert new linecard (MOD80) to my device and it could not register. I found the reason is IOS version is not support this linecard and i have to upgrade to new IOS.
So which IOS-XR version i need to upgrade for RSP4G? And could I upgrade directly from 4.1.2 to 5.1.3 version?
Thank and regards
