Overview
About the Lantronix SISTG1040-282-LRT
Not every edge location needs a managed switch. The SISTG1040-282-LRT (sometimes searched as SISTG1040 282) is a plug-in Layer 2 switch for the edge of a hardened network: eight 10/100/1000Base-T RJ45 ports for cameras, controllers and sensors, and two 100/1000Base-X SFP slots for fiber uplinks. The two SFP ports can also daisy-chain switches together along a line of cabinets. With nothing to configure, it suits harsh-environment sites that need Gigabit connectivity without the overhead of switch management.
Switching is store-and-forward at wire speed, with 20 Gbps switching capacity, a 4K MAC table and jumbo frames up to 9K bytes. IEEE 802.3az Energy Efficient Ethernet trims power on idle links, and total draw is 5.8 W. Power input accepts +12 to +48 VDC or -12 to -48 VDC on redundant inputs with reverse polarity protection. The fanless IP30 metal housing is 44 mm wide and 0.39 kg, operates from -40 to +75 C at 5% to 95% humidity, and carries UL Class 1/Div 2, CE, FCC Part 15 and IEC/EN 62368-1.
Key capabilities
- 8 Gigabit + 2 SFP
- Eight 10/100/1000Base-T RJ45 ports and two dual-speed 100/1000Base-X SFP slots in one compact DIN-rail switch.
- -40 to +75 C fanless
- Fanless, IP30 ruggedized metal enclosure rated for -40 to +75 C operation and 5% to 95% non-condensing humidity.
- UL Class 1 Div 2
- Certified UL Class 1/Division 2 for hazardous locations, with CE, FCC Part 15 and IEC/EN 62368-1 safety approvals.
- Wide DC input
- Redundant +12 to +48 VDC or -12 to -48 VDC inputs with reverse power protection, drawing only 5.8 W.
- Fiber daisy-chain uplinks
- The two SFP slots run at 100 or 1000 Mbps and can link switches in a daisy chain for network reliability across a line of enclosures.
How to choose the right SISTG1040-282-LRT part number
The SISTG1040-282-LRT is a single orderable model with eight Gigabit RJ45 ports and two empty 100/1000Base-X SFP slots; a DIN-rail bracket is included. SFP modules are sold separately, so choose 100 Mbps or Gigabit optics to match the far end. Add WMBH-01 for wall mounting, and power it from a DIN-rail supply such as the 25135 (24 VDC, 10 W) or 25130 (48 VDC, 39.8 W). The OCA-P181610 outdoor cabinet provides DIN rails and wire glands for outdoor installations.

SISTG1040-282-LRT FAQ
Is the SISTG1040-282-LRT a managed or unmanaged switch?
It is unmanaged. It forwards traffic at wire speed using a store-and-forward Layer 2 engine with no configuration required, and offers a reset button plus System, Power1, Power2 and port status LEDs.
What power does the SISTG1040-282-LRT need?
It accepts +12 to +48 VDC or -12 to -48 VDC on redundant inputs with reverse power protection and consumes 5.8 W. Compatible DIN-rail supplies include the 25135 (24 VDC, 10 W) and 25130 (48 VDC, 39.8 W).
What SFP speeds does the SISTG1040-282-LRT support?
Both SFP slots are dual-speed 100/1000Base-X, so they accept 100 Mbps or Gigabit SFP modules. The slots ship empty; modules are sold separately. Use the fiber ports for uplinks or to daisy-chain switches.
Can the SISTG1040-282-LRT be used in hazardous locations?
Yes. Lantronix lists UL Class 1/Div 2 certification, and positions the switch for Gigabit connections in hazardous locations, factory floors and outdoor enclosures, operating from -40 to +75 C.
How is the SISTG1040-282-LRT mounted?
A DIN-rail bracket is included. The WMBH-01 wall mount bracket is available separately. The housing measures 44 x 130 x 135 mm and weighs 0.39 kg.
