In order for the new member unit to work properly within a stack, it needs to have the same firmware
as the Master. A manual update of the firmware can be performed on the new member to synchronize
the firmware prior to cabling it into the stack. Or, another way to accomplish this is to configure the
Master switch to use the boot auto-copy-sw command, which automatically upgrades firmware on new
members as they are added to the stack. In the event the new stack member unit being added has a
newer firmware version, a downgrade will also be allowed. To prevent the downgrade of the new
stack member unit's firmware, the Master needs to be configured with the following command: no boot
auto-copy-sw allow-downgrade. This will allow all new member units to synchronize with the Master
only if the firmware revision of the new members is older than that of the Master. Use the following
commands to set this feature and display the settings.
console(config)#boot auto-copy-sw
console(config)#no boot auto-copy-sw allow-downgrade
console(config)#do show auto-copy-sw
