DATASHEET

The NHM-2126 supports 24 10/100/1000Mbps ports and 2 1Gbps or 2.5Gbps SFP ports. It is an industrial L2 switch. NHM-2126 is a high-speed reliability for smart factories, smart city CCTV, wireless LAN network construction, etc. It is designed to be suitable for places that require network access. Various functions such as VLAN, STP, and QoS are applied, as well as the international standard G.8032 ERPS Ethernet ring protection switching technology. If there is an abnormality in the twork, the ring can be quickly switched and the network can be restored to normal quickly. In addition Various network management functions such as SNMP, RMON, and Web-based Management make it easy to operate the network. It supports operating temperatures from -40 degrees Celsius to 80 degrees Celsius, demonstrating excellent performance even in harsh environments.
