Hardened PoE+ switch for hazardous locations

The Transition Networks SISTP1040-342-LRT is an unmanaged Gigabit Ethernet switch built for harsh environments. It delivers up to 30 Watts on each of four PoE+ ports simultaneously. The unit operates reliably between -40C and +75C. It suits factory floors, outdoor enclosures and other hazardous locations where standard switches would fail.

Check power input and fiber uplink needs

Verify that your installation can supply redundant power connections for continuous operation. Confirm the SFP modules you plan to use match the dual-speed 100/1000 uplink slots. Ensure the DIN rail or wall mounting option fits the available space in your enclosure. The switch complies with IEEE 802.3 at and IEEE 802.3 af for powered device compatibility.

Four copper ports plus two fiber uplinks for daisy

Four 10/100/1000Base-T ports connect PoE devices such as cameras or wireless access points. Two 1000Base-X SFP slots provide fiber uplinks that can be arranged in a daisy chain for maximum network reliability. Redundant power inputs free the system from single-point failures. The hardened design removes the need for climate-controlled cabinets.

Questions about this item

Does the SISTP1040-342-LRT include SFP modules for the fiber uplink ports, or must they be purchased separately?

The switch provides two 100/1000 dual-speed SFP slots; SFP modules are not included and must be sourced separately to match the required fiber type and distance.

When should I choose the four-port hardened PoE+ model over other versions?

Choose this model when you need four Gigabit PoE+ ports delivering up to 30 W each, dual SFP uplinks for fiber or daisy-chain redundancy, and operation from -40 °C to +75 °C in hazardous locations.

What does the 30 W per PoE+ port rating mean for connected devices?

Each of the four 10/100/1000Base-T ports can supply up to 30 W simultaneously, supporting IEEE 802.3 at Class 4 devices such as PTZ cameras or wireless access points without an external injector.
