## Long description

The CRS328-4C-20S-4S+RM is a 28-port rackmount switch combining twenty SFP ports, four SFP+ 10G ports and four combo ports that allow selection between SFP or RJ45 interfaces. Combo ports can be software-selected so you may decide which of the paired SFP or RJ45 interfaces are active. The unit is supplied in a 1U rack case and includes dual 100–240 V power supplies with failover functionality, an RJ45 console port for management and debugging, and a configurable mode button for executing RouterOS commands. It supports dual-boot operation with RouterOS or SwOS.
Advantages
The CRS328-4C-20S-4S+RM provides flexible port configuration with combo ports and software selection, enabling adaptable connection layouts without hardware changes. Redundant power supplies ensure continued operation in case of a PSU failure. The rackmount 1U form factor fits standard network cabinets and the RJ45 console plus configurable mode button simplify local management and troubleshooting. Dual-boot between RouterOS and SwOS allows choice of feature-rich routing or lightweight switching firmware.
Key specifications
 Total ports: 28 (20 SFP + 4 SFP+ 10G + 4 combo SFP/RJ45)
 SFP+ speed: 10 Gbps on four SFP+ ports
 Combo functionality: software-selectable SFP or RJ45 on four combo ports
 Form factor: 1U rackmount

How to use
Install the CRS328-4C-20S-4S+RM in a standard 19" rack using the included mounting hardware and connect AC mains to both power supplies for redundancy. Insert appropriate SFP or SFP+ modules into the corresponding ports and, if using combo ports, choose SFP or RJ45 per port in software or leave the default hardware selection. Access the device via the RJ45 console for initial configuration or use RouterOS/SwOS web/CLI interfaces over the network. Configure the mode button in RouterOS to run specific commands or scripts for quick local actions.
Recommendations
For reliable operation, use compatible SFP/SFP+ modules and keep both power supplies connected. Select RouterOS for advanced routing and scripting features or SwOS for simpler, switch-focused management; test mode-button scripts in a controlled environment before deploying in production.
