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.

help
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
which allows for more memory. Your system is most probably
running in M-Mode, so you should say N here.
