NRS48T4XP

Niveo Professional NRS48T4XP - managed PoE+ L2+ switch with 48 Gigabit Ethernet ports and 4 SFP+ 10G ports, PoE budget 370W, 19" rack 1U

The Niveo Professional NRS48T4XP is a fully managed L2+ network switch with 48 10/100/1000Base-T ports with PoE+ power and 4 SFP+ slots operating in 1G/10G mode, designed for installation in a 19" rack (1U). The switch is intended for medium and large networks, including extensive AV installations, network audio systems, monitoring, and Video-over-IP. All 48 RJ45 ports compliant with IEEE 802.3af/at can power devices with up to 30W per port with a total PoE budget of 370W. Four 10G SFP+ slots serve as uplink connections and allow network expansion from 1G to 10G - providing fast connections to other 10G switches, servers, and workstations, and can also be grouped for link aggregation to increase bandwidth. The non-blocking switching matrix of 176Gbps, performance of 130.94Mpps, 32K MAC address table, and 32Mb buffer ensure smooth handling of high traffic. Support for IEEE 1588v2 (PTP) in transparent clock mode provides precise time synchronization required by advanced audio protocols such as AES67. Advanced PoE management includes power budget control, priorities and power limits for ports, scheduling, PD Alive Check, and Soft-Reboot PoE Non-stop. L2+ features include 4094 active VLAN networks, Q-in-Q, Voice VLAN, STP/RSTP/MSTP with protection mechanisms, ERPS G.8032 ring with switching below 20ms, IGMP Snooping v1/v2/v3 with Fast Leave, and QoS with 8 priority queues. The switch can be managed via the web (HTTP/HTTPS), CLI (console, Telnet, SSH), and SNMP v1/v2c/v3, while advanced security features - 802.1X, 512 ACL rules, RADIUS, TACACS+, and DoS attack protection - safeguard the network infrastructure.
