MikroTik CRS354-48P-4S+2Q+RM PoE Switch

The MikroTik CRS354-48P-4S+2Q+RM is a high-capacity managed PoE switch designed for enterprise networks, data centers, surveillance systems, wireless infrastructure, and other demanding deployments. It provides 48 Gigabit Ethernet ports with PoE output for powering compatible network devices, four 10G SFP+ ports for high-speed uplinks, and two 40G QSFP+ ports for high-bandwidth backbone connections. The switch combines Layer 2 switching with Layer 3 routing capabilities through MikroTik RouterOS and can also operate with SwOS. Its substantial switching capacity, high PoE power budget, multiple fiber uplinks, redundant power options, and 1U rack-mountable design make it suitable for centralized network and device connectivity.

Product Features

48 Gigabit PoE Ports

The CRS354-48P-4S+2Q+RM provides 48 Gigabit Ethernet ports for connecting computers, access points, IP cameras, VoIP phones, and other network devices while delivering compatible PoE power over the Ethernet connection.

High PoE Power Budget

The switch provides a substantial PoE power budget for powering multiple compatible devices from a central network location, helping reduce the need for individual power adapters and electrical outlets.

Four 10G SFP+ Ports

Four SFP+ ports provide 10 Gigabit fiber or direct-attach connectivity for high-speed uplinks, server connections, switch aggregation, and network backbone applications.

Two 40G QSFP+ Ports

Two QSFP+ ports support up to 40Gbps connectivity, providing high-bandwidth uplink options for data center networks, core switches, storage systems, and other demanding infrastructure.

Advanced Layer 2 Switching

The switch provides VLANs, link aggregation, port isolation, spanning tree, port mirroring, and other Layer 2 management capabilities for professional network deployments.

Layer 3 Routing Support

With RouterOS, the CRS354-48P-4S+2Q+RM can provide supported Layer 3 routing functions in addition to switching, allowing it to participate in more advanced network architectures.

Flexible Operating Systems

The switch supports MikroTik RouterOS and SwOS, allowing administrators to select advanced routing and management capabilities or a dedicated switching operating system.

Rack-Mountable 1U Design

The metal 1U enclosure is designed for installation in standard 19-inch racks, making it suitable for server rooms, data centers, network cabinets, and professional IT infrastructure.

Redundant Power Support

Dual power supply inputs provide additional flexibility for installations that require improved power availability and redundancy.

Active Cooling

The switch uses active fan cooling to help maintain operating temperatures during high-throughput switching and PoE workloads.
