Considerations for downgrading firmware To avoid failure of a firmware downgrade, verify the firmware you are downgrading to supports all the blades in the chassis and the firmware you are downgrading to supports all features you are currently using. If not, you will need to disable or remove those features that are not supported. Also, check for any one of the following conditions: • If FC8-32 and/or FC8-48 port blade is inserted on Brocade 48000 director or Brocade DCX enterprise-class platform, power off and remove the blade prior to downgrading the firmware. • If an EX_Port is configured and enabled on any one of the FC8-port blades, reconfigure the port back to default prior to downgrading the firmware. • If port mirroring is configured and enabled on any one of the FC8-port blades, reconfigure the port back to default prior to downgrading the firmware. • If Access Gateway ADS policy is enabled, disable ADS policy prior to downgrading the firmware. • If F_Port Trunking is enabled, disable it first prior to downgrading. Preinstallation messages The messages in this section are displayed if an exception case is encountered during firmware download. The following example shows feature-related messages that you may see if you were downgrading from v5.2.0 to v5.1.0: The following items need to be addressed before downloading the specified firmware: Port mirror connections detected.
