HP 2920-48G

A high-performance HP switch with 44 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.

Hewlett-Packard was founded in the difficult times of the Great Depression. The founders were a pair of friends whose name the company still proudly bears. They started their business in an unobtrusive garage near the city of Palo Alto. It is now a national monument. HP’s success lay not in copying existing products, but in the ability and courage to come up with something new.

The first commercial triumph was an oscillator that surpassed all competition in quality, yet sold at a quarter of the price. In 1968, HP released their first desktop computer - a desktop calculator. The company currently manufactures products primarily related to computer technology - computers and laptops, printers, scanners, digital cameras, servers, and last but not least, calculators.
