SFP cage supports both 1.25 Gb SFP and 10 Gb SFP+ modules.
MikroTik CRS326-24G-2S+RM, Cloud Router SwOS/RouterOS powered 24 port Gigabit Ethernet switch with two SFP+ ports, wire speed connectivity with several new switching features. 800MHz CPU, 512MB, 24xGLAN, 2xSFP+cage, ROS L5, PSU,1U Rackmount. It has additional CPU unit that allows customers to run full RouterOS operating system on this device. CPU unit offers limited processing power, but is sufficient to run few very needed RouterOS features that common smart switches simply doesn't have. It has "Dual boot" feature that allows you to choose which operating system you prefer to use, RouterOS or SwOS. If you prefer to have a simplified switch only OS with more switch specific features, use SwOS. If you are used to Winbox and would like the ability to use routing and other Layer 3 features on some ports in your CRS, boot and use RouterOS.
