NGSME24T4H

Niveo Professional NGSME24T4H - managed PoE+ L2+ switch with 24 Gigabit Ethernet ports and 4 10G SFP+ ports for 19" rack

The Niveo Professional NGSME24T4H is a fully managed PoE+ L2+ switch in a 1U housing for a 19" rack. It is designed for medium and large networks, including AV installations. It has 24 10/100/1000Mb/s RJ45 ports with PoE+ power compliant with IEEE 802.3af/at, delivering up to 30W per port. It powers touch control panels, access points, and IP cameras without separate power supplies. Four 10G SFP+ slots serve as uplink ports. They allow network expansion from 1G to 10G, and link aggregation increases the bandwidth of connections to other switches and servers. For audio and video over IP systems, the switch offers a full set of multicast features: IGMP Snooping with Querier and Fast Leave, as well as IEEE 1588v2 PTP, required by AES67. The PD Alive Check function automatically detects unresponsive PoE devices and restarts their power.
