Overview

The Ruijie RG‑NIS3100‑4GT2SFP‑HP is a fanless, industrial Layer‑2 managed PoE/PoE+ Ethernet switch engineered for harsh environments (dust, salt‑spray, wide temperature range). It provides 4× Gigabit PoE/PoE+ RJ45 ports, 2× Gigabit SFP uplinks and a device PoE budget up to 120 W. Ideal for CCTV, factory automation and coastal installations.

• 4× 10/100/1000Base‑T PoE/PoE+ ports (802.3af/at); 2× 1000Base‑X SFP uplinks.
• Per‑port PoE: 56 V DC, up to 30 W; device PoE budget: 120 W (budget varies with input voltage).
• True industrial build: IP40 aluminium enclosure, conformal coating, ESD/surge immunity, fanless operation, DIN‑rail and wall mounting.
• Layer‑2 features: VLAN (1–4094), STP/RSTP, LAG, IGMP snooping, ACLs, LLDP/LLDP‑MED, RLDP; management via Ruijie Cloud, web GUI and SNMP v1/v2c/v3.
• Redundant DC power inputs (dual 12–56 V DC), removable terminal block and alarm relay output for power failure monitoring.

Use cases

• Surveillance camera networks (PoE/PoE+ powered cameras).
• Factory or automation networks in dusty or coastal environments.
• Remote or outdoor enclosures where fanless, wide‑temperature operation is required.

Compliance & safety

• Meets industry IEC immunity/ESD/surge standards per datasheet; check product label and local regulations for CE/UKCA markings where required.
• Professional installation advised for DC power wiring and earthing in industrial environments.
