Product Features

48 Gigabit Ethernet Ports

The switch provides 48 Gigabit Ethernet ports supporting 10/100/1000 Mbps connections. These ports offer high-density wired connectivity for computers, servers, wireless access points, network printers, IP cameras, and other Ethernet devices.

Four 10G SFP+ Ports

Four SFP+ ports support up to 10Gbps connectivity and can be used for high-speed fiber or direct-attach uplinks, server connections, and switch-to-switch aggregation.

Two 40G QSFP+ Ports

Two QSFP+ ports provide up to 40Gbps connectivity for high-bandwidth backbone connections, data center aggregation, storage infrastructure, and connections to compatible core switches.

High Switching Capacity

The CRS354-48G-4S+2Q+RM offers up to 336 Gbps of switching capacity and up to 168 Gbps of non-blocking throughput, helping accommodate high traffic volumes across multiple connected devices.

Advanced Layer 2 Switching

The switch provides extensive Layer 2 features, including VLANs, link aggregation, port isolation, spanning tree protocols, port mirroring, and traffic management.

VLAN Network Segmentation

IEEE 802.1Q VLAN support allows administrators to separate network traffic into logical segments, improving network organization, security, and traffic management.

Link Aggregation

Link aggregation allows multiple physical network connections to be combined into logical links, providing increased bandwidth and redundancy between compatible devices.

Flexible Operating System Options

The switch supports MikroTik SwOS and RouterOS, giving network administrators the flexibility to use dedicated Layer 2 switching features or additional RouterOS management and routing capabilities.

Rack-Mountable 1U Design

The metal 1U enclosure is designed for standard 19-inch rack installation, making the switch suitable for professional network cabinets, server rooms, and data center environments.

Active Cooling

Built-in fan cooling helps manage operating temperatures during continuous high-throughput network operation.
