The MikroTik CSS326-24G-2S+RM is a cost-optimized Layer 2 managed switch designed for enterprise access layer deployments where high port density meets 10G uplink capability. Built around the Marvell 98DX3216A1 switch chip, it delivers 52 Gbps non-blocking switching capacity with 24 Gigabit Ethernet ports and two SFP+ cages supporting both 1.25G SFP and 10G SFP+ modules. The SwOS operating system provides essential managed switch features through an intuitive web interface, eliminating the complexity of RouterOS while maintaining enterprise-grade VLAN, traffic management, and security controls.

This 1U rackmount switch operates silently with passive cooling and draws only 19W maximum power. Dual power input options—DC jack (10-30V) and passive PoE-IN—offer installation flexibility and backup power capability. With a proven MTBF of approximately 200,000 hours at 25°C and an extended operating temperature range of -40°C to +70°C, the CSS326-24G-2S+RM suits demanding environments from climate-controlled data centers to industrial installations.

What network environments is the CSS326-24G-2S+RM designed for?

This switch is designed for SMB office networks, small ISP aggregation tiers, and edge data center access layers where you need 24 Gigabit ports with 10G uplinks. It handles workstation connectivity, IP camera aggregation, and multi-tenant VLAN segmentation. The fanless design suits office environments requiring silent operation.

How does the CSS326 model differ from the CRS326 series?

The CSS326-24G-2S+RM runs only SwOS and cannot run RouterOS, unlike the CRS326 which supports both operating systems. Storage is reduced from 16MB to 2MB for cost optimization. The CSS version offers the same port configuration and switching capacity at a lower price point, trading RouterOS advanced routing capabilities for simplified Layer 2 management.

Is this switch cost-effective compared to similar managed switches?

The CSS326-24G-2S+RM delivers enterprise managed switch features with dual 10G SFP+ uplinks at a budget-conscious price point. You get non-blocking 52 Gbps switching, VLAN support for up to 4K simultaneous VLANs, and fanless operation without paying for RouterOS licensing or routing features you may not need. It fills the gap between unmanaged switches and full-featured Layer 3 devices.

What systems and modules does this switch work with?

The switch supports both 1.25 Gb SFP and 10 Gb SFP+ modules in its two uplink cages, allowing mixed-speed fiber connections. It integrates with existing networks through IEEE 802.1Q VLAN standard, SNMP v1 monitoring, and MikroTik neighbor discovery. SwOS is web-based and works with any modern browser for configuration. The switch cannot run RouterOS.

What is the actual switching capacity and forwarding performance?

The switch delivers 52 Gbps non-blocking switching capacity with 77.4 Mpps forwarding rate using the Marvell 98DX3216A1 chip. All 24 Gigabit ports plus two 10G SFP+ uplinks can operate simultaneously at full wire speed without bottlenecks. The 16K MAC address table supports enterprise-scale deployments.

Can this switch provide power to connected devices?

This switch does not provide PoE output to connected devices. It accepts passive PoE input (10-30V) for its own power supply as an alternative to the DC jack. You cannot power IP phones, cameras, or access points from this switch's Gigabit ports.

How many VLANs can be configured on this switch?

The switch supports up to 4K simultaneous VLANs following IEEE 802.1Q standard, with a practical configuration limit of 250 VLANs. This capacity handles complex multi-tenant environments, department segmentation, and guest network isolation typical in SMB and ISP deployments.

What management options are available beyond the web interface?

Management is primarily through the SwOS web-based GUI accessible from any modern browser. SNMP v1 support enables integration with network monitoring systems like PRTG or Zabbix. MikroTik neighbor discovery protocol helps identify adjacent MikroTik devices. There is no CLI access, and the switch cannot run RouterOS management tools.
