The NAM is a rack-mountable device that complements data communications networks using other modules; it provides more interfaces, processing power and storage.  The NAM is designed for data centre deployment.  Like the Güralp EAM, it runs the Platinum operating system.  Compared to the EAM, it has much more processing power and more interfaces.  It consumes more power than the EAM, which was designed specifically to be a low power device.
