MikroTiks CRS328-4C-20S-4S+RM cloud router switch has 28 independent ports and a combo group. The CRS328-4C-20S-4S+RM has twenty SFP ports, four SFP+ ports for 10G modules and four combo ports. The combo ports can be used as SFP or RJ45 ports. These ports can also be software selected, so if youhave plugged in all eight cables, you can use scripting to decide which four combo ports will be active.
The switch comes in a 1U rackmount case with two 100-240 V power supplies with failover functionality. An RJ45 console port is available for management and debugging, and a mode button can be customised to execute any RouterOS commands. The CRS328-4C-20S-4S+RM has a “Dual boot” feature that allows you to choose between two operating systems - RouterOS or SwOS.
For a simplified operating system with only switch specific features, select SwOS. RouterOS should be chosen if you would like the ability to use routing and other Layer 3 features in your CRS. You can select the desiredoperating system from RouterOS, from SwOS or from the RouterBOOT loader settings.
