Overview
About the Lantronix SISPM1040-362-LRT
The SISPM1040-362-LRT, part of the SISPM1040-300 Series, connects and powers IP cameras, sensors and roadside equipment in harsh outdoor and industrial locations. It runs from -40 °C to +75 °C, carries UL Class 1 Division 2 safety certification and lists NEMA TS-2 compliance for traffic control cabinets, and Lantronix notes it appears on the Florida DOT Approved Product List. Its 120 W PoE budget supplies a full 30 W to all four PoE+ ports at the same time, so no port has to be derated.
The switch has eight ports in total: four 10/100/1000 PoE+ ports, two 10/100/1000 RJ-45 ports without PoE and two 100/1000 SFP slots. For network resilience it supports G.8032 ERPS, G.8031 linear protection, MRP (IEC 62439-2) and Lantronix Rapid Ring with recovery under 20 ms. Other features include IEEE 1588v2 PTP, 802.1X, 4K VLANs, 256-entry ACLs, LACP, 9.6K jumbo frames, PoE scheduling and Auto Power Reset.
Power input is 48-57 VDC on redundant inputs with reverse-polarity protection, and a 24 VDC/1 A relay output and a digital input support alarm wiring. The embedded Device Management System gives integrators topology, floor and map views of connected devices, and a Lantronix plug-in integrates with Milestone XProtect VMS.
Key capabilities
- Full 30 W per port
- A 120 W budget powers all four PoE+ ports at a full 30 W simultaneously, so higher-draw outdoor cameras never compete for power.
- Sub-20 ms ring recovery
- Rapid Ring recovers in under 20 ms, with G.8032 ERPS, G.8031 EPS and MRP available for standards-based ring and linear protection.
- Extended temperature rating
- Operates across -40 °C to +75 °C at 5-95% humidity in an IP30 housing, with shock, vibration and free-fall testing listed.
- Traffic and hazardous-location ready
- Lists NEMA TS-2 and UL Class 1 Division 2 certification, and Lantronix reports placement on the Florida DOT Approved Product List.
- Redundant DC inputs
- Dual 48-57 VDC inputs with reverse polarity and overload protection, plus a 24 VDC/1 A relay output for alarm signaling.
- Milestone XProtect integration
- The DMS and the LantronixInstallerV03.01b plug-in connect the switch to Milestone XProtect VMS for camera-network visibility.
How to choose the right SISPM1040-362-LRT part number
There is one orderable switch, SISPM1040-362-LRT, with a DIN-rail bracket included. Choose it over larger SISPM1040 models when four PoE+ cameras plus two non-PoE devices and two fiber uplinks are enough. Plan the rest of the installation with the accessories: WMBH-01 for wall mounting, the 25104 or 25105 DIN-rail power supplies or the PS-DC-DUAL-5624T 56/24 VDC supply, the OCA-P181610 outdoor cabinet, the EDCA-DIO-01 door contact alarm, and Lantronix SFP modules for the two fiber slots.

SISPM1040-362-LRT FAQ
How much PoE power does the SISPM1040-362-LRT deliver?
It has a 120 W PoE budget and can deliver 30 W to all four PoE+ ports simultaneously. It complies with IEEE 802.3af and 802.3at and supports PoE scheduling and Auto Power Reset. Without PoE load it consumes 8.2 W.
What power input does the SISPM1040-362-LRT need?
It requires 48-57 VDC on redundant inputs with reverse-polarity and overload protection. Lantronix lists the 25104 DIN-rail supply (48-55 VDC, 240 W), the 25105 supply and the PS-DC-DUAL-5624T 345 W dual-output supply as compatible accessories.
What ring redundancy protocols does it support?
It supports ITU-T G.8032 ERPS, G.8031 Ethernet linear protection, Media Redundancy Protocol (IEC 62439-2) and Lantronix Rapid Ring with recovery under 20 ms. A DIP switch sets the Rapid Ring configuration, and STP, RSTP and MSTP are also supported.
Is the SISPM1040-362-LRT certified for traffic cabinets and rail?
It lists NEMA TS-2 and UL Class 1 Division 2 among its certifications. EN50155, EN50121-4, DNV, IEC 61850-3 and IEEE 1613 are listed as designed-to-meet, and Lantronix asks buyers with those certification needs to contact them.
