Upgrading SPA FPD Images
• Swapping SPAs
If you are swapping SPAs from another platform or from the same platform that is running a
different Cisco IOS XR software release, the system notifies you to if it is necessary to perform an
upgrade.
• Inserting a new SPA
SPA FPD Image Upgrade Task List
This section describes the guidelines and tasks to perform an FPD image upgrade on a SPA for FPGA
version upgrades, or other supported FPD version upgrades. This section includes the following topics:
• SPA FPD Image Upgrade Guidelines, page 7-5
• Upgrading FPD Images for SPAs in a Production System, page 7-5
• Upgrading SPA FPD Images, page 7-5
SPA FPD Image Upgrade Guidelines
• The SPA will probably be in the FAILED state if you do not have the required FPD image
downloaded on it.
• Upgrading the FPD image on a SPA places the SPA offline and interrupts traffic. An image upgrade
requires approximately 30 seconds to complete depending on the SPA.
Upgrading FPD Images for SPAs in a Production System
When the FPD image is upgraded on the SPA, the SPA is shutdown and traffic through the SPA interfaces
is rerouted. Therefore some packets may get dropped if the upgrade is performed on a production system.
The performance impact will vary depending on the type of processing engine used and the type of
service configured.
Because of the potential problems, we highly recommend that one of the following alternatives be used
to perform the upgrade if possible.
• Upgrade the FPD image on SPAs on a non-production system that is running the same Cisco IOS XR
software image that you are running on the production system that the SPAs will be inserted into.
• Upgrade the FPD image on SPAs during a maintenance window when there is no traffic passing
through the system.
If you are not sure whether the SPA requires an FPD upgrade, you can install the SPA and use the show
hw-module fpd command to determine if the FPD image on the SPA is compatible with the currently
running Cisco IOS XR software release.
Upgrading SPA FPD Images
To upgrade the current FPD version on a SPA card, use the following command in admin EXEC mode:
upgrade hw-module fpd {all | fpga} [force] location [all | node-id]
The node-id refers to the location of the module in the rack/slot/module notation. Currently only the
FPGA image can be upgraded on your SPA. If the SPA you want to upgrade is already in the shutdown
state, then you must use the force option to upgrade it. You can also use the force option to perform the
upgrade even if there is no image version incompatibility.
