Description
The MikroTik CRS328-4C-20S-4S+RM is optimized for large organizations and ISPs, features twenty SFP ports, supporting speeds up to 1GbE, ideal for fiber optic or copper connections. It also integrates four advanced SFP+ ports, capable of managing up to 10GbE speeds—a staple in current network environments. Furthermore, this switch presents four versatile combo ports, enabling users to choose between RJ45 and SFP connections. Plus, the device's customization capabilities ensure a tailored network experience for users.The CRS328 runs on the robust 98DX3236 chipset, operating at 800 MHz. Complemented by a substantial 512 MB of RAM, this configuration is tailored for dedicated network devices, managing tasks from buffering and routing tables to overseeing the device's OS operations. The standout feature of this device, however, is its Marvell switch chip. Renowned in both consumer and enterprise spheres, Marvell's chips excel in efficiently handling data plane operations. This translates to swift packet forwarding, adept VLAN management, and an overall streamlined data traffic experience, ensuring your network realizes its full potential.The CRS328 is designed for optimal performance: with its non-blocking Layer 2 switching, every port runs at top speed without congestion. Boasting a 16K host table, the switch can track a vast number of devices, ideal for large-scale networks. It supports up to 4,000 VLANs, ensuring thorough network segmentation. With the incorporation of STP, RSTP, and MSTP, network loops are effectively prevented. For security, the CRS328 uses Access Control Lists to filter traffic and Port Security to limit device access. The inclusion of Port Mirroring provides real-time network monitoring. Furthermore, the CRS328 utilizes enhanced jumbo frames for increased performance, manages multicast traffic via IGMP Snooping, and leverages IEEE 802.3ad to bond ports together, resulting in faster and more stable connections.The device is securely encased within a 1U rackmount frame, ensuring long-lasting durability. Equipped with two 100-240 V power supplies, it features failover capabilities to ensure uninterrupted operation. For administrators and IT professionals, a dedicated RJ45 console port provides a direct interface for in-depth network management and troubleshooting activities.The "Dual boot" functionality in the MikroTik CRS328 provides users with the option to select between two distinct operating systems based on their specific needs. Users can opt for RouterOS, renowned for its comprehensive routing features, or SwOS, tailored for switch-specific functions. This feature allows users to precisely configure functions ranging from basic port-to-port forwarding to more complex adjustments in MAC and IP headers.FeaturesHardware Features:•Product code: CRS328-4C-20S-4S+RM•CPU: 98DX3236A1 800 MHz•RAM: 512 MB•Storage type: Flash•Storage size: 16 MB•Switch chip model: 98DX3236A1•SFP cages: 20•SFP+ cages: 4•Ethernet/SFP Combo ports: 4•Operating system: SwOS / RouterOS (Dual boot)•Supported input voltage: 100 - 240 V•Dimensions: 443 x 200 x 44 mm•Operating temperature: -20°C, +60°C tested•Max power consumption: 43 W•Serial port: RJ45•License level: 5
