## Long description

The Mikrotik CRS328-4C-20S-4S+RM is a 28-port managed L2/L3 rackmount switch with a 128 Gbit/s switching capacity and a MAC address table of 16,000 entries. It provides twenty SFP ports, four SFP+ ports for 10G modules and four combo ports that allow selection between SFP and RJ45 interfaces. The device is delivered in a 1U chassis with dual 100–240 V power supplies and supports software selection of combo ports and a dual-boot option between RouterOS and SwOS.
Advantages
The CRS328-4C-20S-4S+RM offers flexible port configuration through software-selectable combo ports and separate SFP+ 10G connectivity, enabling mixed fiber and copper deployments. Redundant power supplies with failover improve availability for rack environments, while the dual-boot ability lets administrators choose RouterOS for advanced routing and switching features or SwOS for simplified switch management. An RJ45 console port and a customizable mode button facilitate local management and scripting.
Suitable for
 Server room and data center top-of-rack switch deployments
 Mixed fiber and copper uplinks requiring both 1G SFP and 10G SFP+ ports
 Network aggregation and distribution for small to medium enterprise networks
 Environments needing power redundancy and remote management

How to use
Mount the switch in a 1U rack space and connect both power supplies to independent power sources for redundancy. Insert appropriate SFP or SFP+ modules into the fiber ports and connect RJ45 cables to combo ports when using copper; use the software port-selection feature to activate the desired interface in each combo pair. Access the device via the RJ45 console port or through network management using RouterOS or SwOS. Use the customizable mode button to run predefined RouterOS commands or scripts for quick local actions.
Usage recommendations
For stable operation, deploy both power supplies and configure failover; choose RouterOS for advanced L3 routing features and SwOS for simplified switch-only management. When fully populated, use scripted port-selection to control which combo ports are active to avoid link conflicts.
