This switch is an unmanaged full Gigabit Ethernet hardened PoE+ switch that complies with IEEE 802.3at and IEEE 802.3af. The switch has (4) 10/100/1000Base-T PoE+ ports with two 100/1000 dual speed SFP slots. It can deliver up to 30 Watts on each PoE+ port simultaneously. The SISTP1040-342-LRT can be used at the edge of a hardened network to provide connections for PoE devices in hazardous locations. 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 -40C and +75C. 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.Total Number of Network Ports: 4Uplink Port: YesModular: YesStack Port: NoPort/Expansion Slot Details: 4 x Gigabit Ethernet NetworkPort/Expansion Slot Details: 2 x Gigabit Ethernet Expansion SlotMedia Type Supported: Twisted PairMedia Type Supported: Optical FiberEthernet Technology: Gigabit EthernetNetwork Technology: 10/100/1000Base-TNetwork Technology: 1000Base-XNumber of Total Expansion Slots: 2Expansion Slot Type: SFP (mini-GBIC)Shared SFP Slot: NoNumber of SFP Slots: 2Layer Supported: 2Manageable: NoPower Source: Power SupplyRedundant Power Supply Supported: NoForm Factor: Wall MountableForm Factor: DIN Rail MountableHeight: 1.7Width: 5.3″Depth: 5.4″Weight (Approximate): 15.20 ozLimited Warranty: 5 Year”
