The MikroTik CRS112-8G-4S-IN is a versatile and compact device from MikroTik's Cloud Router Switch series, offering a combination of switching and routing capabilities. It is designed with small to medium-sized businesses (SMBs) and home offices in mind, providing a robust networking solution within a desktop form factor. The device features 8 Gigabit Ethernet ports for high-speed wired connections and 4 SFP ports, which allow for flexible fiber connectivity, supporting both single-mode and multi-mode fiber modules. This port variety ensures that the device can accommodate a wide range of networking setups.
Running on a 400 MHz single-core CPU with 128 MB of RAM and 16 MB of flash storage, the CRS112-8G-4S-IN supports wire-speed Ethernet switching and offers Layer 3 features. The device is powered by an external adapter and supports passive Power over Ethernet (PoE), making it easy to deploy in various environments. Its compact dimensions (200 x 143 x 44 mm) and maximum power consumption of 13W make it an energy-efficient choice for network infrastructure.
The CRS112-8G-4S-IN runs on MikroTik's RouterOS, a powerful operating system that provides a wide array of networking features, including routing, firewall, bandwidth management, and more. This OS can be managed through a web-based GUI, command-line interface (CLI), or MikroTik's Winbox application, offering flexibility in how network administrators choose to configure and maintain their network.
This device is particularly well-suited for small to medium-sized offices that require reliable and high-performance networking. Its ability to handle both Ethernet and fiber connections makes it a versatile choice for diverse networking needs. Additionally, branch offices can benefit from its capability to connect multiple Ethernet devices while providing fiber connectivity where needed.
While the CRS112-8G-4S-IN offers substantial functionality, it's important to consider that its CPU and RAM may limit performance for very demanding tasks or extremely large networks. Furthermore, while RouterOS is powerful, it may present a steep learning curve for those unfamiliar with MikroTik's systems. Despite these considerations, the MikroTik CRS112-8G-4S-IN stands out as a reliable, feature-rich, and cost-effective solution for SMBs and home offices looking to enhance their network capabilities with a device that efficiently combines switching and routing functionalities.
