MikroTik CRS328-4C-20S-4S+RM 28-Port Managed Rack Switch

The MikroTik CRS328-4C-20S-4S+RM is a managed Layer 2 rack switch delivering 28 independent ports in a compact 1U rackmount chassis — making it a capable and flexible network switch for high-density fibre deployments.

Dense SFP Connectivity With 10G Uplink Support

• 20 dedicated SFP ports for standard 1G fibre modules, ideal for connecting multiple network segments or access switches.
• 4 SFP+ ports support 10G modules, providing high-throughput uplinks to core infrastructure.
• 4 combo ports (SFP or RJ45) can be software-selected via RouterOS scripting, giving you flexibility when all eight cables are connected simultaneously.
• Dual boot capability lets you choose between RouterOS and SwOS, adapting the device to different management preferences.
• Redundant dual power supplies (100–240 V) with failover functionality reduce the risk of unplanned downtime.

This switch suits network administrators and IT teams building structured fibre backbone networks in server rooms, data centres, or enterprise environments where port density, 10G uplinks, and software-defined management are priorities.
