The CRS328-4C-20S-4S+RM is a switch with 28 ports that can work independently or in a combo group. You can use twenty SFP ports, four 10G SFP+ ports, and four ports that support either SFP or RJ45 cables. You can also switch between the ports in the combo group with software scripts if you have connected all eight cables. The device fits in a 1U rackmount case and has two power supplies that can back up each other. It also has an RJ45 console port for management and debugging and a mode button that you can customize to run any RouterOS commands. The device lets you choose between two operating systems – RouterOS or SwOS – with the “Dual boot” feature.
