Appendix C Firmware Upgrade and Downgrade Procedures
Using the Procedure Tables
Using the Procedure Tables
Each of the eight tables includes the procedure for a particular type of upgrade or downgrade, and for
a particular core card set. For example, one table shows the procedures for a graceful upgrade on a one
core card set, another table shows the procedures of a standard downgrade for a two core card set.
The tables, A through H, are as follows:
• A = Standard upgrade, 1-core card set
• B = Standard upgrade, 2-core card set
• C = Standard downgrade, 1-core card set
• D = Standard downgrade, 2-core card set
• E = Graceful upgrade, 1-core card set
• F = Graceful upgrade, 2-core card set
• G = Graceful downgrade, 1-core card set
• H = Graceful downgrade, 2-core card set
Each row in a table corresponds to a particular “from” release and each column in a table corresponds
to a particular “to” release.
By looking down to the appropriate row and across to the appropriate column, the cell (or position) in
the table indicates the number of the procedure to be used. An em dash in a table indicates that no
procedure is supported for that particular upgrade or downgrade.
