The MikroTik CRS328-24P-4S+RM is a 24-port Gigabit PoE Cloud Router Switch designed for access-layer deployments that require reliable power delivery and high-speed uplinks. With support for multiple PoE standards and four 10G SFP+ ports, it is well suited for networks powering access points, IP cameras, and other PoE devices while maintaining fast aggregation to the core.

Where the CRS328 is commonly used

• PoE access switching for enterprise and SMB networks
• Powering wireless access points and IP cameras
• Edge switching with 10G fiber uplinks to core switches
• Surveillance, VoIP, and IoT deployments

The CRS328 provides 24 Gigabit Ethernet ports with flexible PoE output options, including passive PoE, low-voltage PoE, and IEEE 802.3af/at (PoE and PoE+), with automatic detection. The built-in 500 W power supply delivers up to 450 W of available PoE power, allowing each port to supply up to 30 W for demanding devices.

Four SFP+ ports provide up to 10 Gbps connectivity for fiber or Ethernet uplinks, making the CRS328 suitable for aggregation into 10G core or distribution switches. The non-blocking switching architecture ensures consistent performance across all access and uplink ports.

The CRS328 supports dual boot operation, allowing you to choose between RouterOS or SwOS. SwOS provides a simplified interface focused on switching features, while RouterOS enables advanced routing, VLANs, and Layer 3 functionality when required. The operating system can be selected through RouterBOOT or software settings.

Housed in a 1U rack-mountable enclosure, the CRS328 includes an internal 100–240 V AC power supply and is designed for reliable operation in wiring closets and network racks.
