Description
Niveo Professional NGSME24T2H - managed PoE+ switch L2+, 24 Gigabit Ethernet ports and 2 SFP ports, PoE budget 500W (Current Sharing)
Niveo Professional NGSME24T2H is a fully managed PoE+ switch layer L2+ with 24 10/100/1000Base-T ports and 2 SFP 100M/1G slots, totaling 26 ports. The RJ45 ports support PoE+ power according to IEEE 802.3af/at with up to 30W per port and a range of up to 100m. Current Sharing technology allows two internal power modules to work together and provide a PoE power budget of 500W. If one module fails, the other takes over and continues to deliver 250W. When devices then require more power, the switch first powers the ports with the highest priority. The switch powers access points, IP cameras, and other network devices directly through the existing LAN cable. The SFP slots allow connection of servers, storage, or other switches via fiber over long distances and also support 100M modules. This is a good choice for medium and large networks, AV installations, monitoring, and wireless networks.
The L2+ management package includes up to 4K VLAN 802.1Q networks, QinQ, Protocol VLAN, Private VLAN, MVR, QoS with 8 queues, IPv4/IPv6 multicast filtering with IGMP and MLD Snooping, RSTP and MSTP protocols, LACP, LLDP, sFlow, port mirroring, and cable diagnostics. Security is ensured by HTTPS and SSH, MAC address binding to ports, 802.1X access control, web-based and MAC address authentication, AAA authentication with RADIUS and TACACS+ servers, and ACL lists. The PD Alive Check function periodically checks the powered device, e.g., an IP camera, by IP address. If the device does not respond, the switch restarts the port power. Out-of-band management is provided by the CLI console port, while in-band management is done via SNMP and the Web GUI.
Functionality
