Switch Ethernet Gigabit L2 Gerido MikroTik CRS354-48G-4S+2Q+RM — 48x Gigabit RJ-45, 4x SFP+, 2x QSFP+, 10G, Montagem em rack

The MikroTik CRS354-48G-4S+2Q+RM is a managed L2 Gigabit Ethernet switch designed for rack installation. It provides 48 x 1G RJ45 ports, 4 x 10G SFP+ ports and 2 x 40G QSFP+ ports, offering high-density connectivity and non-blocking throughput suitable for busy network environments. With a switching capacity of 336 Gbps and a forwarding rate up to 235 Mpps, the unit supports demanding traffic loads while preserving efficient data transfer and full-duplex communication.

Advantages

The switch combines a large number of Gigabit RJ45 ports with high-speed 10G and 40G uplink options, enabling flexible network designs and aggregation. Managed L2 features and a console port allow for centralized control and configuration in rack-mounted installations. The device balances performance and cost, providing a high switching capacity and non-blocking throughput for multi-device environments.

Suitable for

• Enterprise access layer with many wired endpoints
• Data aggregation and uplinks to core switches or servers
• Rack-mounted network closets and server rooms
• Environments requiring 10G/40G fiber uplinks

How to use

Mount the CRS354-48G-4S+2Q+RM in a standard 19-inch rack using the supplied brackets. Connect powered devices to the RJ45 ports for gigabit access and use the SFP+ or QSFP+ ports for 10G/40G uplinks or fiber connections. Access the management interface via the console port or network management protocols to configure VLANs, link aggregation, spanning tree and other Layer 2 features. Observe standard safety and grounding procedures during installation.

Recommendations

For optimal performance, use quality SFP+/QSFP+ modules and appropriate cabling for 10G/40G links, enable link aggregation for higher throughput to servers, and monitor traffic to prevent congestion. Keep firmware up to date and configure management access securely.
