DATASHEET

The NSH-2252P is a high-performance L2 PoE switch that supports 24 10/100/1000Mbps PoE ports and 4 10Gbps uplink SFP+ ports. It supports various L2 functions such as VLAN, STP, and QoS, and network management functions such as SNMP, RMON, and Web based Management make it easy to operate the network. In addition, it supplies stable power by providing 15W or 30W class IEEE 802.3af/at standard PoE for stable access to CCTV cameras, Internet phones, and wireless LAN APs. If a CCTV camera, wireless LAN AP, etc. connected to the PoE port malfunctions and needs to be rebooted, it resets the power of the PoE port so that it can be processed remotely without visiting the site, providing convenient operability.
