Cumulus Linux cannot be installed on early revisions of the Dell N3048EP-ON switch.
You cannot install Cumulus Linux on the A0 and A1 revisions of the Dell N3048EP-ON switch because its internal storage is only 1GB, which is insufficient to contain the operating system. You can install Cumulus Linux on revision A02 of the switch.
If you try to install Cumulus Linux on one of these earlier revisions, you get an error, and the OS does not install.
To determine the revision you have, boot into ONIE and run the
onie-syseeprom command. Look for the Label Revision field. If its value is A00 or A01, then you have one of the older, incompatible revisions.
