Enabling or Disabling Automatic Upgrades of EPLD Images

You can enable or disable automatic upgrades of EPLD images for I/O modules. When enabled, the
switch checks the EPLD image versions on newly installed or powered up I/O modules to see if they are

switch. If the images on the I/O modules are older, the switch automatically upgrades the images to the
newer versions.
