Note
Before updating the next line card, wait about 30 seconds after the
Cisco IOS software reloads on the line card to give the router a chance to
synchronize all of its internal functions.

Upgrading an FPGA Image on a Line Card
When the Cisco IOS image boots, it verifies that a compatible FPGA image is
running on the router. The major version number of the FPGA image must be the
same as that expected by the Cisco IOS image; the minor version number on the
FPGA image must be the same as or greater than the minor version number
expected by the Cisco IOS image.
running on the router. The major version number of the FPGA image must be the
same as that expected by the Cisco IOS image; the minor version number on the
FPGA image must be the same as or greater than the minor version number
expected by the Cisco IOS image.
For example, if the Cisco IOS image expects a minimum FPGA image of 03.02,
the software verifies that the actual major version number of the FPGA image in
the line card bootflash is 03, and that the minor version number is 02 or above.

If a line card does not boot and an error message indicates that there is a problem
with the FPGA image, or if the line card alphanumeric LED display remains stuck
in the IOS STRT stage, you must upgrade the FPGA image using the diag
command.
