MikroTik Cloud Router Switch CRS328-4C-20S-4S+RM is a manageable MikroTik switch equipped with 4 (SFP + Ethernet) Combo ports, 20 SFP slots and 4 SFP+ slots. These ports can also be selected programmatically, so if you have all eight cables connected, you can use scripts to decide which four combo ports are active. With Dual Boot the user can select one of the two operating systems on the device, SwitchOS or RouterOS (Level 5).
SwitchOS provides Layer2 functionality, supports IEEE 802.1Q up to 4K VLAN ID at the same time, security port, port isolation, IGMP Snooping and connection aggregation. Using RouterOS we have full access to Layer3 functions similar to other MikroTika products, which can be useful.
The CRS328-4C-20S-4S+RM runs on a Marvell 8DX3236A1 processor with 800 MHz and a chip 98DX3236A1 known from the CRS328-24P-4S+RM or CRS326-24G-2S+RM. Additional advantage of the device is 512 MB RAM. Maximum throughput (non-blocking) is 64 Gb/s and transfer speed is 95.2 Mp/s. The device is delivered in a 1U rack 1U enclosure with two 100-240V power supplies with failover function. The RJ45 console port is available for management and debugging, and the mode button can be customized to execute any RouterOS commands.

MikroTik RouterOS is the operating system of the router and software that allows the PC or Mikrotik RouterBoard to be a dedicated router.
No, the configuration will not be removed from one version family. When upgrading version families (for example V2.5 to V2.6) you may lose configuration of some features that have major changes. For example, when upgrading from V2.4, you must first upgrade to the latest version 2.4.
RouterBOARD is a hardware platform from MikroTik, which is a line of routers with RouterOS operating system. Almost all models of RouterBOARD devices can be powered via Ethernet (PoE) and have a connector for external power source.
