I keep having to look this up, so I’m just going to write it here quick.
1. Download firmware (finally on dell.com)
2. Copy to usb stick or tftp server
3. Do the upgrade.
Here’s how it works:
OS10# copy run start
(if tftp) OS10# image download tftp://filename.bin
OS10# image install usb://filename.bin
OS10# show image status
