1. Product Description
This switch is an unmanaged full Gigabit Ethernet hardened PoE+ switch that complies with IEEE 802.3at and IEEE
802.3af. The switch has eight 10/100/1000Base-T PoE+ ports with two 100/1000 dual speed SFP slots. In many
fields such as Solar, Vehicle, or Factory systems, there are no standard power input requirements of 52 to 57
volts for PoE devices. The SISTP1040-382B-LRT uses booster technology to let you deploy the PoE switches with
power input of 12, 24, or 48~57 volts. It can still deliver up to 30 Watts on each PoE+ port. The two fiber 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. Lantronix hardened
switches are certified to operate reliably in harsh environments such as those found on factory floors, outdoor
enclosures or other hazardous environments.
Features
•Support Jumbo Frame up to 9K bytes
•Layer 2 wire-speed switching engine
•Ruggedized metal closure
•IEEE802.3az Energy Efficient Ethernet
•Fanless design
•Wide operating temperature range (-40°C to +70°C)
•Dual Power input
•Din Rail and Wall Mount options
