Please remove the configuration using "portcfglongdistance L0" CLI or change the configuration with -distance option. Downgrade is not allowed because Location ID is configured.

Blade types Where blades are incompatible with a firmware download, they must be removed or powered off before a firmware download begins, as noted in the following message. Message Probable cause and recommended action The FC10-6 (type 39) blade is not supported by the target firmware. Please use slotshow to find out which slot it is in and remove it first. The firmware download operation was attempting to upgrade a system to Fabric OS v7.4.0 with one or more of the Brocade FC10-6 blades (blade ID 39) in the system. The Brocade FC10-6 blades are not supported on firmware v7.4.0, so the firmware download operation failed. Use the slotShow command to display which slots the Brocade FC10-6 blades occupy. Physically remove the blades from the chassis, or use the micro-switch to turn the blade off. Retry the firmware download operation. Firmware versions The system messages in this section refer to differences between the current firmware and the firmware you are applying to the switch. ATTENTION Brocade does not support upgrades from more than one previous release. For example, upgrading from Fabric OS v7.3.0 to v7.4.0 is supported, but upgrading from Fabric OS v7.2.0 or a previous release directly to v7.4.0 is not. In other words, upgrading a switch from Fabric OS v7.2.0 to v7.4.0 is a two-step process: first upgrade to v7.3.0, and then upgrade to v7.4.0. If you are running a pre-Fabric OS v7.0.0 version, first you must upgrade to v7.0.0, then to v7.1.0, then to v7.2.0, then to v7.3.0, and finally to v7.4.0.
