Description

Product Overview

NEXCOM system nROK 7271 accomplishes operational efficiency of public transportation and service. Based on Intel® 12/13th Gen FCLGA1700 socket-type CPU and 4/12-port 802.3 af/at PoE, it provides an integral solution incorporating high computing power. With dual SIM cards per modem support, it allows two SIM cards backup for a better connectivity quality through software. RAID 0, 1 guarantees the safety of data in the 2 x external SSD. The nROK 7271 further distinguishes itself to provide power isolation for 24~110VDC and optional up to 3-sec protection against temporary voltage dips, a feature critical for scenarios where input voltage variability may shut down the equipment. With daughter board expansion design, optional for an additional 1 x mini-PCIe slot (BOM optional for M.2 Key E) and 2 x M.2 Key B slot, 8-port 1Gbps Ethernet Switch GbE, PoE 802.3af/at, max. 30W, or 2-port 10GbE M12 X-coded, nROK 7271 keeps the flexibility to meet the demand for different rolling stock applications, such as infotainment, transportation cellular router, video server, and video surveillance.
