1.  Overview

CS-Z8102AX-M2-T is a 5G+WIFI6 household CPE router that accesses the Internet through 5G mobile communication dial-up or a 1000Mbps WAN port, and then shares the Internet network through wireless WiFi 6 and a 1000Mbps wired LAN.

2. Standard

Relevant standards and specifications:

• USB3.0/USB2.0 bus standard
• SIM/USIM interface standard
• IEEE802.11n/g/b/a/ac/ax
• IEEE802.3/802.3u/802.ab
• PCI Express M.2 Specification Rev1.
• The 5G mobile communication standard is specifically determined by the selected 5G mobile communication module

4. Watchdog function

This hardware product is designed with a hardware watchdog function. After being powered on, the hardware watchdog will automatically boot up and detect the heartbeat level output by the routing system, which changes once every second. If the routing system itself experiences a fault (such as a crash), it will naturally be unable to output the heartbeat level. At this time, if the hardware watchdog fails to detect the heartbeat level within 120 seconds, it will automatically shut down for 15 seconds and then restart the entire system.

When the routing system is functioning normally and the 5G module is experiencing dial-up issues, the routing system will control the power supply of the 5G module through GPIO, causing the module to automatically restart in order to fix the 5G dial-up issue.

5. 5G Mobile Communication Function

This product is equipped with two built-in M.2 interfaces, which can be used to expand dual-module 5G mobile communication capabilities. The built-in M.2 interfaces support USB3.0 bus. Whether 5G mobile communication specifically supports NSA or SA, and which frequency bands are supported, depends on the selected 5G module.
