The nodes of Origin, Onyx, Fuel and Tezro systems can be configured

in either N-Modes which allows for more nodes or M-Mode which allows

for more memory. Your hardware is almost certainly running in

M-Mode, so choose M-mode here.

The nodes of Origin 200, Origin 2000 and Onyx 2 systems can be

configured in either N-Modes which allows for more nodes or M-Mode

running in M-Mode, so you should say N here.
