  • 28 independent ports with four combo SFP or RJ45 options
  • Twenty SFP plus four SFP+ cages for flexible fibre uplinks
  • Dual 100-240 V AC supplies with failover for continuous operation
  • Dual-boot RouterOS or SwOS lets you pick the OS
  • 1U rackmount chassis with console port and programmable mode button

28-port SFP/SFP+ switch

The CRS328-4C-20S-4S+RM provides twenty SFP cages, four SFP+ cages for 10G modules and four combo ports selectable between SFP and RJ45. A single ARM 32bit CPU at 800 MHz runs either RouterOS or SwOS, giving Layer 3 routing or pure switching operation. Dual 100-240 V AC inputs with failover keep the unit running if one supply fails.

Before ordering

Confirm that your rack can accept a 1U device measuring 443 x 200 x 44 mm and that you have SFP or SFP+ transceivers matching the fibre type and distance you need. The four combo ports share physical cages, so only four of the eight possible connections can be active at once. Console access uses an RJ45 serial cable, not a standard DB9 or USB adapter.

Build integration

The switch consumes up to 43 W and includes PCB temperature and voltage monitors for remote health checks. A programmable mode button can trigger custom RouterOS scripts during maintenance windows. Sixteen megabytes of flash storage and 512 MB RAM hold configuration files and logs without external media. Operating range of -20 to +60 °C suits standard server rooms and hardened cabinet deployments.

Questions about this item

What comes in the box with the CRS328-4C-20S-4S+RM and what must be purchased separately?

The switch includes a 1U rackmount case, two internal 100-240 V AC power supplies with failover, an RJ45 console port and a programmable mode button. SFP and SFP+ transceivers for the 20 SFP and 4 SFP+ cages are not included and must be bought separately.

Which version or capacity of the CRS328-4C-20S-4S+RM should I choose?

This model is a single SKU with 28 independent ports: 20 SFP cages, 4 SFP+ cages for 10G modules and 4 combo ports that can be software-selected as SFP or RJ45. Choose it when you need that exact port mix and dual-boot RouterOS or SwOS.

What does the 43 W maximum power consumption mean once the switch is installed in a rack?

At full load the switch draws up to 43 W from either of its two 100-240 V AC inputs, which provide automatic failover. It operates in ambient temperatures from -20 °C to +60 °C, so the 43 W figure represents the peak heat output your rack cooling must handle.
