Upgrading a Single Stack Unit
Upgrading a single stacked switch is necessary when the unit was disabled due to an incorrect FTOS
version. This procedure upgrades the image in the boot partition of the member unit from the
corresponding partition in the master unit.
To upgrade an individual stack unit with a new FTOS version, follow these steps:
Figure 17-32 shows an example of how to upgrade an individual stack unit.
