## Summary description

The MikroTik CRS328-4C-20S-4S+RM is a managed L2/L3 switch designed for efficient networking. It features a switching capacity of 128 Gbit/s and supports up to 16000 MAC address entries. Ideal for rack mounting with a 1U form factor, it adheres to IEEE networking standards including 802.1Q and 802.3ad, making it suitable for various network environments.

## Long description

The MikroTik CRS328-4C-20S-4S+RM is a managed L2/L3 rackmount switch offering 28 independent ports in a 1U chassis and a switching capacity of 128 Gbit/s. It includes twenty SFP ports, four SFP+ ports for 10G connectivity and four combo ports that allow software selection between SFP and RJ45 interfaces. The unit supports up to 16,000 MAC address entries, dual power supplies with automatic failover and a dedicated RJ45 console port for management. The device provides dual-boot capability to run either RouterOS or SwOS.
Advantages
The CRS328-4C-20S-4S+RM combines high-density SFP and SFP+ connectivity with flexible combo port selection and scriptable control over which combo interfaces are active, enabling adaptable port usage. Redundant power supplies with failover increase operational reliability in rack deployments, while a hardware mode button and console port simplify on-site management and debugging. Support for IEEE standards such as 802.1Q and 802.3ad ensures interoperability with VLAN tagging and link aggregation implementations.
Suitable for
Data center top-of-rack switching with a mix of 1G and 10G fibre connections
Service provider aggregation and distribution layers requiring many SFP ports
Enterprise networks needing VLAN segmentation and link aggregation
Rack-mounted network infrastructures where redundant power is required
Key specifications

10G support: SFP+ ports for 10G modules
MAC address table size: up to 16,000 entries
Form factor: 1U rackmount
Power: dual 100–240 V power supplies with failover
Management interfaces: RJ45 console port, scriptable mode button
Standards: IEEE 802.1Q (VLAN), IEEE 802.3ad (LACP)
Operating systems: Dual boot (RouterOS or SwOS)
Product colour: White
How to use
Install the switch into a 19-inch rack using the included 1U brackets and connect the AC power inputs to redundant power sources. Populate SFP and SFP+ slots with compatible transceivers or use the combo RJ45 ports as required; use the software selection feature or scripting to enable the desired combo interfaces. Access the device through the RJ45 console port for initial configuration or via RouterOS/SwOS web/CLI management once network connectivity is established. Configure VLANs, LACP link aggregation and routing features according to network design and save the chosen operating system using the dual boot selector.
Usage recommendations
Use compatible SFP/SFP+ modules recommended by your network design and ensure firmware and RouterOS/SwOS are kept up to date. When deploying in a critical environment, connect both power supplies to separate circuits and test failover behavior. For automated control of combo ports, implement scripted selection during maintenance windows to avoid accidental link disruption.
