Housed in a rugged IP40 metal enclosure, it features four 10\/100\/1000Base-T(X) RJ45 copper ports and two 100\/1000Base-X SFP slots for flexible optical connectivity. Built to operate reliably in harsh temperatures ranging from -40°C to +75°C, this managed switch supports a variety of crucial Layer 2 capabilities, including STP\/RSTP, IEEE 802.1Q VLAN, QoS, port mirroring, and IGMP snooping. It features robust 8kV surge protection on all twisted-pair ports and accepts redundant dual DC power inputs to ensure uninterrupted network uptime in industrial settings.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features \u0026amp; Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCopper Interfaces:\u003c\/strong\u003e 4x 10\/100\/1000Base-T(X) RJ45 ports with 8kV surge protection.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOptical Interfaces:\u003c\/strong\u003e 2x 100\/1000Base-X SFP slots (transceivers sold separately).\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManagement \u0026amp; Protocols:\u003c\/strong\u003e Web-based and SNMP v1 management; supports STP\/RSTP, IGMP snooping v1, IEEE 802.1Q Tag VLAN, port VLAN, QoS, CoS, bandwidth control, and cable diagnostics.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower Input:\u003c\/strong\u003e Redundant dual DC inputs (10-56V DC) with reverse power polarity protection.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnvironmental Ratings:\u003c\/strong\u003e Hardened for extended operating temperatures from -40°C to +75°C.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnclosure \u0026amp; Mounting:\u003c\/strong\u003e IP40 rated rugged metal housing; includes DIN-rail mounting kit.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompliance:\u003c\/strong\u003e Industrial Grade EMS, EMI, EN61000-6-2, EN61000-6-4 certified.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cdl\u003e\n  \u003cdt\u003eDoes the HGW-402LM switch come with a power supply?\u003c\/dt\u003e\n  \u003cdd\u003eNo, this industrial switch requires an external DC power source (10-56V DC).
