SI-IES-111D-LRT has one SFP slot and one RJ45 port. The RJ45 port supports 802.3at (PoE+), and can provide 30W for high powered application. The SFP slot provides more flexibility when planning and implementing the network. The slot can accept either a 100m or 1000m SFP module. This makes it possible to easily change the transmission mode and distance of the connection by using a different module. The SFP module is hot-swappable, and there is a dip switch to adjust the LFP function.
