We have received an new switch from Extreme X450-G2-48P-10GE-4 but it has version 30 code pre installed on both partitions - our customer is currently running 184.108.40.206patch1-7 - so we need to downgrade it - however when we try to do this from USB to the inactive partition we get this error message
X450G2-48p-10G4.2 # download image memorycard summitX-220.127.116.11-patch1-7.xos primary
Do you want to install image after downloading? (y - yes, n - no, <cr> - cancel) Yes
Downloading to Switch............................
Error: Failed to download image - summitX-18.104.22.168-patch1-7.xos does not include compatible PoE controller support. See the User Guide for information on installing a newer software release. See the Hardware/Software Compatibility and Recommendation Matrices to verify the supported release
I have not seen this before and never had trouble before downgrading non 30 code to earlier - have looked at the release notes and could not see this error message quoted anywhere. any ideas why this is - and how we fix it ?
