HP 2920-24G

A high-performance HP switch with 20 RJ-45 ports supporting data transfer rates of up to 1 Gb/s. It also has four dual personality Gigabit ports and a separate dual-personality RJ-45/USB port. Its impressive performance makes it particularly suitable for connecting corporate computers, disk stations, and servers. The switch supports almost all security, configuration, and communication protocols to allow you to use this network element to the fullest.

The switch is designed for 1U rack, where it can join other network elements. This model has a triple-core processor clocked at 625 MHz and 512 MB RAM to facilitate smooth data transmission. The switch can be configured through the built-in console port. You can use the command line, web browser, or the configuration menu.
