| Description | Switch 20 ports 10/100/1000 + 4x dual-personality ports (J9726A) Extra powerful switch from HP 20 ports RJ-45 supporting data rates up to 1 Gb/s It also four dual personality Gigabit ports and a separate port dual-personality RJ-45/USB . Its impressive performance is particularly suitable for integrating corporate computers, disk stations and servers. The switch has the support of almost all security, configuration and communication protocols to enable maximum utilization of the network element. Along with other elements of your network place it in a rack, where it takes the position 1U. For smooth transmission of data this model has 3jádrovým processor at a frequency of 625 MHz and memory capacity 512 megabytes . The switch can be configured via the built-in console port via the command line, web browser or via the configuration menu.
