I recently had the opportunity to review the Mikrotik CRS309 1G 8S IN switch. After spending several weeks testing and using this device, I am pleased to report that it is an excellent networking switch. This device offers a great combination of power and portability.

The CRS309 1G 8S IN has eight SFP slots, with each slot supporting up to 10 Gbit/s module for a total switching capacity of 162 Gbps and a total non blocking throughput of 81 Gbps. It also features a dual core 800 MHz CPU, 512 MB RAM, a management Ethernet port with PoE power input, RS232 serial port and a grounding terminal. All these features make this device ideal for businesses looking for an efficient and reliable network switch.

The CRS309 1G 8S IN is also capable of dual booting, allowing users to choose between RouterOS or SwOS operating systems according to their needs. Moreover, its sleek metallic enclosure serves as a heatsink, making this device passively cooled without any fan noise or dust accumulation inside. Additionally, it comes with special rackmount ears that enable easy installation in standard racks.

The CRS309 1G 8S IN is an excellent choice for small to medium business networks as well as home networks due to its high performance and reliability.
