Dell PowerEdge FN I/O Module Configuration Guide 9.10(0.0)

To upgrade all switches in a stack with the same Dell Networking OS version, follow these steps.

1. Copy the new Dell Networking OS image to a network server.
2. Download the Dell Networking OS image by accessing an interactive CLI that requests the server IP address and image filename, and prompts you to upgrade all member stack units. EXEC Privilege mode upgrade system { flash: | ftp: | scp: | tftp: | usbflash: } partition Specify the system partition on the master switch into which you want to copy the Dell Networking OS image. The system then prompts you to upgrade all member units with the new Dell Networking OS version. The valid values are a: and b:.
3. Reboot all stack units to load the Dell Networking OS image from the same partition on all switches in the stack. CONFIGURATION mode boot system stack-unit all primary system partition
4. Save the configuration. EXEC Privilege write memory
5. Reload the stack unit to activate the new Dell Networking OS version. CONFIGURATION mode reload
