DNOS 6.x:
This is the operating system running on the Dell Networking N-series (campus) networking switches. It is the latest version of the 'PowerConnect' operating system, running on a Linux Kernel. It is available as upgrade for the PowerConnect 8100 series switches (which then become a Dell Networking N40xx switch) and it also is installed on all DN N2000 and N3000 series switches. It has a full web-based GUI together with a full CLI (command line interface) and the CLI will be very similar to the original PowerConnect CLI, though with a range of new features like PVSTP (per VLAN spanning tree), Policy Based Routing and MLAG.

DNOS 9.x:
This is the operating system running on Dell Networking S- and Z- series switches and is a further development of the FTOS or Force10 Operating System. Standard DNOS 9.x (and FTOS) only offers a CLI and no GUI, although with the automation toolset it is possible to create your own webGUI on DNOS9 / FTOS switches. DNOS 9.x is running on NetBSD.
Only the PowerConnect 8100 will be able to run on DNOS 6.x: all other PowerConnect ethernet switches will continue to run its own PowerConnect OS (on top of VxWorks) while the PowerConnect W-series run on a Dell specific version of ArubaOS. The Dell Networking S- xxxx and Z9x00 series will run on DNOS where the other Dell Networking switches will continue to run FTOS 8.x firmware.
