MikroTik RouterBOARD CRS328-4C-20S-4S+RM

Smart Switch, 20 x SFP cages, 4 x SFP+ cages, 4 x Combo ports (Gigabit Ethernet or SFP), 800MHz CPU, 512MB RAM 1U rackmount case, Dual Power Supplies, RouterOS L5 or SwitchOS (Dual Boot)

The CRS328-4C-20S-4S+RM is a 28 independent port switch with a combo group. This device has twenty SFP ports, four SFP+ ports for 10G modules and four combo ports, where you can choose to use SFP or RJ45 ports from the combo group. These ports can also be software selected, so if you have plugged in all eight cables, you can use scripting, to decide which four combo ports will be active.

The device comes in a 1U rackmount case with two 100-240 V power supplies with failover functionality. A RJ45 console port is available for management and debugging, and a mode button can be customised to execute any RouterOS commands.

The device has a “Dual boot” feature that allows you to choose between two operating systems - RouterOS or SwOS.
