D-Link DES-1024D

Compact network switch with 24 Ethernet RJ-45 ports supporting speeds of 10 and 100Mbps. The device is designed for use in smaller offices. The device has a 512kB buffer that is dynamically allocated.
Of course, it supports half-duplex and full-duplex, with which the switch has double the data throughput over the hub. NWay Autosensing automatically detects the speed of the connected computer or other hub to optimally adjust data flow. Of course, there is a self-signalling function that allows cross-cables to be connected to switches. For easy control, it includes a set of LEDs that tell you if each port is active as well as power, speed, or collision. 
There is no fan in the device, so the switch is suitable for deployment directly at the workstation or as a cable rack.
