HP J9979A network switch
HPE 1820 switches are available in various configurations and provide high network flexibility. They are designed for small organizations that need simplicity, low total cost of ownership and high network performance. These devices are easy-to-administer Gigabit Ethernet Layer 2 switches with intelligent management and fixed configuration that support the latest energy-saving features. Switches with Plug-and-Play technology are completely ready to work, but if necessary, you can perform more precise configuration of network operations through an intuitive web interface.
These HPE 1820 Series switches support the latest energy-saving features such as Energy Efficient Ethernet (EEE), powering off inactive ports, and PoE port usage scheduling. Power can be supplied to a model with 8 Gigabit Ethernet ports from an uplink switch with PoE support. This is convenient for environments where there is no power line. All switches are covered by a limited lifetime warranty.
