The PAT4000 series homegrown controllable IT-innovation Patriot Layer-3 mining industrial switch is an industrial Ethernet switch independently developed by MRD (Shanghai Boying Communication Technology Co., Ltd.) on domestic CPU, switch chip, PHY, OS and software, delivering security and controllability from PHY to core software, with whole-unit localization rate of 100%.
The PAT4000 series homegrown controllable IT-innovation Patriot Layer-3 mining industrial switch is designed for high-intensity, high-reliability mining networks, supporting 24 Gigabit copper + 8 GE/FE auto-sensing SFP + 8×10G/1G auto-sensing SFP with flexible media/bandwidth options for underground, open-pit and dispatch-center industrial environments.
The PAT4000 series homegrown controllable IT-innovation Patriot Layer-3 mining industrial switch supports management features such as IGMP snooping and IEEE 802.1Q
VLAN, port-based VLAN, QoS and port mirroring and other network management features ensure efficient, secure data transfer. The PAT4000 series homegrown controllable IT-innovation Patriot Layer-3 mining industrial switch supports Ethernet redundancy (RSTP/STP/MSTP) to improve reliability and backbone availability, plus multiple Layer-3 routing protocols for complex topologies and routing. Simple rich management and flexible mounting make it especially suitable for multi-scenario mining access and deployment. It features a rugged aluminum alloy housing for industrial environments with optional fiber connectivity.
The cable is connected, but the port will not come UP / the link is down. What should I check?
+What are the PoE power specifications?
+Which ring protocols are supported, and what is the self-healing time?
+How should I choose between Layer-2 and Layer-3 industrial switches?
+Can non-OEM SFP optical modules work normally?
+How do I restore factory settings if I forget the device login password?
+What are the power supply requirements for industrial switches?
+What are the operating temperature range and protection rating of industrial switches?
+Core CPU, switch chip and PHY use domestic chips with domestic-IP Linux OS
