The NRS48T4XP is 24-port 10/100/1000M PoE+ with 4-port 10G SFP+ Open Slot Rack-mount Full Managed PoE+ Switch. The switch supports IEEE 802.3at Power over Ethernet standard, with high power budget per system. The switch is standard 1u, 19” rack-mount design to fit into the rack environment. With these features, the switch is a superb choice for medium or large network environment to strengthen its network connection and efficiency.



NRS48T4XP (28- Port 10/100/1000Base-T PoE + 4 10 Gigabit SFP+ L2+ Management PoE+ Switch)

IEEE 802.3at Power over Ethernet (PoE) ports
This switch features 24 IEEE 802.3at Power over Ethernet (PoE+) ports supplying up to 30 watts per port. This product can convert standard 100~240V/AC power into low-voltage DC that runs over existing LAN cable to power up IEEE 802.3at compliant network accessories.

4 x 10 Gigabit SFP+ Open Slots
The switch equips with 4 10G SFP+ open slots as the uplink ports, the 10G uplink design provides an excellent solution for expanding your network from 1G to 10G. By 10G speed, this product provides high flexibility and high bandwidth connectivity to another 10G switch or the Servers, Workstations and other attached devices which support 10G interface. The user can also aggregate the 10G ports as Trunk group to enlarge the bandwidth.

Full Layer 2+ Management Features
The switch includes full Layer 2+ Management features. The software set includes up to 4K 802.1Q VLAN and advanced Protocol VLAN, Private VLAN, MVR…advanced VLAN features. There are 8 physical queues Quality of Service, IPv4/v6 Multicast filtering, Rapid Spanning Tree protocol to avoid network loop, Multiple Spanning Tree Protocol to integrate VLAN and Spanning Tree, LACP, LLDP; sFlow, port mirroring, cable diagnostic and advanced Network Security features. It also provides Console CLI for out of band management and SNMP, Web GUI for in band Management.

Multicasting To support Video-over-IP
The switch has a full set of multicasting feature, such as IGMP querier, snooping and Fast Leave. It will support any mainstream Video-over-IP platform out there.

IEEE-1588 PTP for advanced Audio
To support advanced audio features and protocols like AES67, the NGSME24T4H switches support IEEE-1588 PTP.

PD Alive Check

When this function is enabled, The NRS24T4P will detect a network PoE powered device (for example, an IP CAM) with a set of IP address periodically.
