before downgrading the firmware.
Message Only platform option 5 is supported by version 6.1.0. Use chassisconfig to reset the option before
downloading the firmware.
Probable cause and recommended action
The firmware download operation was attempting to upgrade a system to Fabric OS v6.1.0. The
chassisConfig option was set to 1, 2, 3 or 4, which are not supported in v6.1.0, so the firmware
download operation was aborted.
Execute the chassisConfig command with a supported option (5 for Brocade 48000 and the
Brocade DCX enterprise-class platform on v6.1.0), and then retry the firmware download operation.
The supported options are:
Message Only platform option 5 is supported by version 6.0. Use chassisconfig to reset the option before
downloading the firmware.
Probable cause and recommended action
The firmware download operation was attempting to upgrade a system to Fabric OS v6.0.0. The
chassisConfig option was set to 2, 3 or 4, which are not supported in v6.0.0, so the firmware
download operation was aborted.

OS v5.3.0; and 5 for Brocade 48000 and the Brocade DCX enterprise-class platform on v6.0.0),
