in order to support new hardware.

we try to upgrade from version s72033-advipservicesk9_wan-mz.122-18.SXF13.bin to c7600s72033-advipservicesk9-mz.122-33.SRB4.bin.

due to the new version will check chassis type.

the original type is OSR-7609, please advise how to fix this issue in order to support SIP400 with SPA-5X1GE-V2 on OSR-7609.

looking forward to hearing from you soon.

thank you very much.

You "might" want to do some research on the 12.2(33)SX* release and see if that works for you.

Please read the documentation carefully (especially unsupported hardware section) to figure out your compatibility.
