CRS328-4C-20S-4S+RM: flexible fiber-first switching with smart combo ports

Meet a 28-port switch built for dense fiber and adaptable copper. You get:

• 20 × SFP ports
• 4 × SFP+ ports for 10G modules
• 4 × combo ports (SFP or RJ45)

The combo group is software-selectable: even with all eight connectors plugged in, you can script exactly which four combo ports are active—perfect for automated failover or dynamic reconfiguration.

Built for the rack, ready for redundancy

Housed in a 1U rackmount chassis with dual 100–240 V AC power supplies providing failover for continuous operation. There’s also an RJ45 console for direct management and troubleshooting, plus a mode button you can customize to run any RouterOS command sequence.

Choose your OS: switching simplicity or L3 features

Leverage the Dual boot capability to run either:

• SwOS for a streamlined, switch-only experience, or
• RouterOS when you need routing and other Layer-3 functionality.

CRS328-4C-20S-4S+RM—dense fiber, clever combos, and the right OS for every job.
