NEXCOM nROK 7252-WI2-C8S

Fanless Rolling Stock Computer with Intel® 8th/9th Gen Core™/Xeon® CPU

NEXCOM system nROK 7252 accomplishes operational efficiency of public transportation and service. Based on Intel® Coffee Lake S/Refresh 8th/9th Gen Core™/Xeon® LGA1151 socket-type CPU and 8-port 802.3 af/at PoE, it provides an integrated solution incorporating high computing power. with dual SIM cards per modem support, it allows six SIM cards to backup each other for a better connectivity quality by software. In addition, six SIM cards and three WWAN modules architecture can increase the bandwidth for a faster data transmission speed. RAID 0, 1, 5, 10 guarantees the safety of data in the 2 x external SSD. nROK 7252 keeps the flexibility to meet the demand for different rolling stock applications, such as infotainment, transportation cellular router, video server, and video surveillance.
