Outdoor PoE switch conforms to the IEEE802.3af/802.3at standard and provides power to standard PoE terminals by wire netting, eliminating the need for additional power wiring.
1, we need to supply power to power devices: PoE switches use different standards and output power varies. The PoE switch, which follows the IEEE802.3at standard, provides power to devices with a maximum power consumption of not more than 25W.
2, how many devices can be powered at most: an important indicator of the PoE switch is the total power supplied by the PoE.
3, the number of interfaces required, whether or not with an optical port, with no network management, speed (10/100/1000M).
