8 100BaseTx, 2 dual rate SFP PoE+ switch with low voltage input, unmanaged, hardened


  • Unmanaged full Gigabit Ethernet hardened PoE+ switch
  • 8x 10/100/1000Base-T PoE+ ports
  • 2x 100/1000 dual speed SFP slots.
  • Suitable for  vehicle, factory or solar systems
  • Uses booster technology to allow power input of 12 to 24 volts.
  • Up to 30 Watts on each PoE+ port.
  • Two fibre uplink ports can also be used in a daisy chain
  • Redundant input power connections




This switch is an unmanaged Gigabit Ethernet hardened PoE+ switch that complies with IEEE 802.3at and IEEE 802.3af. It has (8) 10/100/1000Base-T PoE+ ports with (2) 100/1000 dual speed SFP slots.    In many fields such as vehicle, factory or solar systems, there are no standard power input requirements of 52 to 57 volts for PoE devices. The SISTP1040-382B-LRT uses booster technology to allow the user to deploy the PoE switches in the power input range of 12 to 24 volts. It can still deliver up to 30 Watts on each PoE+ port. The two fibre uplink ports can also be used in a daisy chain for maximum network reliability. It has redundant input power connections to ensure safe reliable operation in temperatures between -40°C and +70°C. Transition Networks’ hardened switches are certified to operate reliably in harsh environments such as those found on factory floors, outdoor enclosures or other hazardous environments.


Technical Notes

What is Power over Ethernet ?

Power over Ethernet, commonly abbreviated to PoE, is a technology that enables DC power to be delivered over the same twisted pair copper cabling as the data. This allows end devices such as IP phones, CCTV cameras and wireless access points to receive power across the network and avoids the need to install electrical cabling and a power source at the remote end.
