The NEXCOM nROK 7271 system delivers operational efficiency for public transport and service. Intel® 12th/13th Gen FCLGA1700 socket-type CPU and 4/12-port 802.3 af/at PoE form the basis of an integrated solution that houses high computing power. With dual SIM card support per modem, two SIM cards can back each other up for better connection quality by software. RAID 0, 1 with 2 x external SSD guarantees data security. The nROK 7271 further differentiates itself with power isolation for 24~110VDC and optional protection against transient voltage drops of up to 3 seconds, a critical feature for scenarios where input voltage variability could shut down the equipment. With its daughter-board expansion design, an additional 1 x mini-PCIe slot (BOM optional for M.2 Key E) and 2 x M.2 Key B slots, an 8-port 1 Gbps Ethernet Switch GbE, PoE 802.3af/at, max. 30 W or 2-port 10 GbE M12 X-coded, the nROK 7271 retains the flexibility to meet the demands of different rolling stock applications such as infotainment, transportation cellular routers, video servers and video surveillance.
