There is nothing special about the X2-ZR units, they are fully compliant
with X2 spec, just have longer reach. Lack of "support" means there's no
entry in your IOS for ZR - but it was already added into 12.2(50)SE.

So either upgrade to 12.2(50)SE2 or use service unsupported-transceiver
in your present IOS and everything will work as expected. We're using
them in production with 12.2(44)SE1 for several months already.

   With kind regards,
