This is a DIGITUS Fast Ethernet network switch for use in a 19-inch server rack, equipped with 24 PoE network ports and a total Power over Ethernet budget of 370 W. The switch has 2 combined Gigabit uplink ports (RJ45/SFP) and is intended for fixed installation in network environments. This network switch is used to provide network devices such as IP cameras, access points, and VoIP devices with data and electrical power via a single Ethernet cable. The switch is unmanaged and operates without configuration. Mounting in a 19-inch rack is possible; placement outside a rack is also suitable. The switch supports Power over Ethernet according to IEEE 802.3af and IEEE 802.3at. The PoE functionality provides DC voltage via the Ethernet cable according to Mode A. The store-and-forward switching method and non-blocking forwarding are intended to fully check data packets before they are forwarded. The PD-Alive function is intended to monitor connected PoE devices and automatically reactivate them when no network response is detected.
