This section explains the FPD automatic upgrade feature, its limitations across hardware types and releases, and the expected FPD status after a software upgrade.
FPD automatic upgrade is a system capability that
-
upgrades FPD firmware versions of all the components to the latest version along with software activation,
-
ensures all the FPD components show CURRENT status after the software upgrade, and
-
retains the upgraded FPD version even when the software image is rolled back to the original version.
From Release 7.9.1, FPD automatic upgrade is enabled by default. You can manually disable it using the fpd auto-upgrade disable command. Before upgrading from a release earlier than Release 7.9.1 to Release 7.9.1, clear any existing FPD configuration using the no fpd auto-upgrade command to ensure that the automatic upgrade is active after the upgrade.

Automatic FPD upgrade |
Cisco IOS XR Release 7.9.1 |
The automatic FPD upgrade functionality is now enabled by default. It upgrades the FPD components' firmware version to the latest version. This enhancement eliminates the need to explicitly enable the functionality using the fpd auto-upgrade enable command. As a result, the software upgrade is simplified, and the system always maintains the latest state of the FPD firmware version. |
From Release 25.4.1, the automatic FPD upgrade process is supported in 1.2T, 1.2TL, QDD, and QXP line cards. It is not supported in the OTN-XP line card.
FPD automatic upgrade is supported for the BP_SSD and CPU_SSD FPDs only if the SSDs are programmed with the latest firmware. FPD automatic upgrade for BP_SSD and CPU_SSD works without manual intervention when upgrading from Release 7.5.2 to a later release. If upgrading from a release earlier than Release 7.5.2 to Release 7.5.2, SSDs use the old firmware. In this scenario, manually upgrade BP_SSD and CPU_SSD FPDs, even if FPD automatic upgrade is enabled.
FPD automatic upgrade is not supported on the LC_DP_MOD_FW FPD of the OTN-XP card because the upgrade affects traffic.
FPD automatic upgrade is not supported for POWMAN_CFG. During a system upgrade to Release 7.5.2 or a later release, manually upgrade POWMAN_CFG if it is not running the latest version. Manually upgrading POWMAN_CFG does not affect traffic.
