HP 1820-48G

HP 1820-48G Switch provides a flexible extension of Ethernet networks in smaller enterprises that require ease of use and low cost. This model brings the ease of administration via a web interface even without extensive technical knowledge. Fanless design is characterized by low noise, it can be placed almost anywhere (wall, on a table, under the table). Allows installation into standardized boxes Rack (19 "), all for the installation is supplied with the device.

Switch provides 48 copper RJ-45 ports support 100/1000 Mbit/s data transmission in local area network and 4 SFP ports. The distribution priority data streams ensures Quality of Service (QoS). Low energy consumption is ensure through an improved solution of Energy Efficient Ethernet (IEEE) and system PoE (Power over Ethernet).
