NSH-2128P is a high-performance PoE switch that supports 24 10/100/1000Mbps PoE ports and 4 Gigabit uplink ports. You can easily operate the network with various functions such as VLAN, STP, QoS, and various network management functions such as SNMP, RMON, and Web based Management. In addition, it provides stable power by providing 15W or 30W IEEE 802.3af/at standard PoE for stable connection to CCTV cameras, Internet phones, and wireless LAN APs. If a CCTV camera or wireless LAN AP connected to a PoE port malfunctions and requires a reboot, the power to the PoE port can be reset and processing can be done remotely without visiting the site, providing convenient operability.
