Overview
About the Lantronix SISPM1242-582-LRT
The SISPM1242-582-LRT (also searched as SISPM1242-582) brings multi-gigabit PoE++ to places a rack switch cannot go: traffic cabinets, outdoor enclosures and factory panels. It is a new Lantronix hardened-grade switch certified for -40°C to +75°C operation on DC input, in a 62 mm wide IP30 housing with a DIN-rail bracket included. Its four 100M/1G/2.5G ports deliver up to 90 W each for PTZ cameras, Wi-Fi 6 access points, digital signage and smart lighting that need more than 1 Gbps or more than 30 W.
The 360 W PoE budget supports PoE++ on four ports and PoE+ on all eight at once. Two 1G/10G SFP+ slots carry aggregated traffic upstream, backed by 68 Gbps switching capacity and a 16K MAC table. Dual 52 to 57 VDC terminal-block inputs feed the switch, which draws 13 W without PoE. Certifications include NEMA TS-2, UL 2108, FCC Class A, CE and UL62368-1.
Beyond Layer 2, the switch supports IPv4/IPv6 static routing and RIPv1/v2 and OSPFv2/v3 dynamic routing. Resilience features include MRP, ITU-T G.8031/G.8032 protection, Rapid Ring and IEEE 1588v2 PTP. The built-in Device Management System adds topology mapping and traffic monitoring, alongside APR, PoE scheduling and Always-on PoE.
Key capabilities
- 2.5G PoE++ ports
- Four 100M/1G/2.5G RJ-45 ports deliver up to 90 W each under IEEE 802.3bt, matching the bandwidth and power of Wi-Fi 6 APs and UHD cameras.
- 10G SFP+ uplinks
- Two 1G/10G SFP+ slots aggregate camera and access point traffic to the backbone without bottlenecking the 2.5G edge ports.
- -40 to +75°C rating
- Certified for -40°C to +75°C operation with DC input, plus NEMA TS-2 and UL 2108, for roadside cabinets and outdoor security enclosures.
- Layer 3 routing
- Static IPv4/IPv6 routing plus RIPv1/v2 and OSPFv2/v3 let the switch route between subnets at the edge, not just switch within a VLAN.
- Industrial ring redundancy
- Media Redundancy Protocol, G.8032 ring protection and Rapid Ring recovery keep linear and ring topologies running after a fiber or link failure.
- Smart PoE control
- Auto Power Reset reboots unresponsive devices, PoE scheduling sets power by port, day or time, and Always-on PoE holds power through reboots and upgrades.
How to choose the right SISPM1242-582-LRT part number
SISPM1242-582-LRT is a single orderable configuration: four 10/100/1000 ports, four 100M/1G/2.5G PoE++ ports, two 1G/10G SFP slots, a console port and 52-57 VDC input, with the DIN-rail bracket included. The switch needs a DC source, so size a supply to the PoE load: the 25104 DIN-rail supply delivers 240 W, the 25160 delivers 480 W for the full 360 W budget, and PS-DC-DUAL-5624T provides 345 W with 56 VDC and 24 VDC outputs. For outdoor sites, the OCA-P181610 cabinet and EDCA-DIO-01 door contact alarm are listed as accessories.

SISPM1242-582-LRT datasheets & documentation
SISPM1242-582-LRT FAQ
How many PoE++ ports does the SISPM1242-582-LRT have?
Four. The four 100M/1G/2.5G ports support IEEE 802.3bt PoE++ at up to 90 W. With the 360 W budget, the switch supports PoE++ on those four ports and PoE+ on all eight copper ports.
What power supply does the SISPM1242-582-LRT need?
It accepts dual 52 to 57 VDC inputs on a terminal block. To use the full 360 W PoE budget, choose a listed compatible supply such as the 480 W 25160. The 240 W 25104 suits lighter PoE loads.
What is the operating temperature of the SISPM1242-582-LRT?
The switch is certified to operate from -40°C to +75°C with DC input. Its housing is rated IP30, and it carries NEMA TS-2 and UL 2108 certifications for traffic and security installations.
Does the SISPM1242-582-LRT support Layer 3 routing?
Yes. It supports IPv4 and IPv6 static routing and RIPv1/v2 and OSPFv2/v3 dynamic routing, along with Layer 2 features such as VLANs, QinQ, LACP, MSTP and IGMP and MLD snooping.
How is the SISPM1242-582-LRT managed?
It is managed through the web GUI, CLI, SSH and SNMP v1/v2c/v3. The integrated Lantronix Device Management System adds graphical topology mapping, traffic monitoring and automated device management for connected PoE devices.
