15.2008.3000

The issue is caused by an incorrect initialization flow of backplane connections implemented in the affected switch firmware versions.
Note: Only downlinks to nodes in the HPE Apollo k6000 Gen10 chassis are affected. All the external connections (uplinks) from the switch will still be functional.
