This PoE switch has eight Gigabit RJ45 ports that can output different power options: 802.3af/at PoE/PoE+ or Passive PoE. It also has four SFP ports for up to 1 Gbps uplinks via optical fiber.
The switch has 12 independent switching ports and comes with a 28 V 3.4 A power supply. It also has a secondary DC jack that supports a 48-57 V power supply (not included, sold separately – product codes 48POW (1.46A 70W) and 48V2A96W (2A 96W)). The switch can power 802.3af/at devices if 48-57 V DC input is used (it will automatically detect and provide the right power). The max current is 1 A per port if 18-28 V input is used, or 450 mA if 48-57 V. The total limit is 2.8A@24V and 1.4A@48-57V. PoE-Out is delivered over mode B 4,5 (+) and 7,8 (-) pins
