Example 13 shows how the software reports the current and new EPLD versions for a module that has
EPLD images that can be upgraded. According to this report, each of the downloaded Linksec Engine
EPLDs has a different version than the same EPLD on the module, so the software will upgrade those
EPLDs but will not upgrade the other EPLDs that have the same version numbers. If the new versions
have a smaller version number compared to the current version, the software will downgrade the
versions.

Upgrading the EPLD Images for I/O or Standby Supervisor Modules
You can upgrade the EPLD images for an I/O module or standby supervisor module while the system is
operational. If you need to upgrade EPLD images for a system with a single supervisor module, see the
“Upgrading EPLDs for the Active Supervisor Module” section on page 6-34.
Caution Upgrading EPLD images for an online I/O module can disrupt traffic going through that module.
