The controller with its very compact dimensions of 230 (W) x 173 (D) x 66 (H) mm has four PoE + interfaces, two 2.5 "hard disk slots and additional I / O connections. The four Gigabit network connections with PoE can deliver 25.5 W of power to connected PD devices (powered devices, e.g. IP cameras).

For data storage, in addition to the eMMC with 32 GB on the Xavier module, the NRU-120S is equipped with an M.2 socket (2280 NVM Express) for fast SSD reading and writing and two hard disk slots. The two hot-swappable 2.5-inch slots for SSD or HDD are conveniently accessible on the front and can therefore be exchanged quickly and easily.
