PAT4000 Series all-domestic 28-port rackmount Layer-2 industrial switch is self-developed by MRD (Shanghai Boying) on domestic CPU, switch chip, PHY, OS and software—secure and controllable from PHY to core software. Uses 100% domestic parts with 100% localization.
PAT300 Series indigenous controllable Patriot full Layer-3 industrial switch supports 16×GE copper + 8×1G/10G or 8×FE/GE SFP, or 8×GE copper + 8×1G/10G or 8×FE/GE SFP—suited to large industrial networks.
PAT300 Series indigenous controllable Patriot full Layer-3 industrial switch supports IGMP Snooping, IEEE 802.1Q VLAN, port-based VLAN, QoS and port mirroring. Ethernet redundancy via RSTP/STP/MSTP improves reliability and backbone availability; multiple Layer-3 routing protocols, rich yet simple management and flexible mounting suit complex access scenarios. Rugged aluminum alloy housing for industrial use with optional fiber.
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 HarmonyOS
