Cisco Cisco IOS XR Software Release 4.0

To upgrade the fabric-downloader, ROMMON, Mbus, and current field-programmable device (FPD) 
image package on a single RMA linecard or on all modules installed in a router, use the upgrade all 
command in administration EXEC mode.

upgrade all location {node-id | all} [force] 

Where location node-id specifies that all ROM images will be upgraded on the physical location of the 
line card received through RMA defined by the node-id argument. The node-id argument is entered in 
the rack/slot/module notation. 

The upgrade all location all command upgrades all ROM images on all line cards (LCs) that are 
installed in the router. 

For an RMA linecard firmware upgrade you’ll want to use the upgrade all location {node-id} 
command.

The optional force parameter skips the version check and forces an upgrade. 

The list of minimum supported firmware versions is available online in this matrix:
