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

	  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.
