MikroTik CSS326-24G-2S+RM 24-Port Gigabit Managed Switch
MikroTik CSS326-24G-2S+RM is a 24-port Gigabit Ethernet managed switch designed for business networks, server rooms, CCTV networks, office infrastructure, structured cabling deployments and other wired networking environments.
The switch provides 24 × 10/100/1000 Gigabit Ethernet ports together with 2 × SFP+ ports supporting high-speed fiber or copper modules up to 10Gbps. It runs SwOS, MikroTik’s dedicated switch operating system, providing web-based management and Layer 2 switching features.
24× Gigabit Ethernet Ports
The main connectivity of the MikroTik CSS326 comes from its 24 individual Gigabit Ethernet ports. Each RJ45 interface supports 10/100/1000 Mbps Ethernet with automatic speed negotiation.
These ports can be used for computers, IP phones, wireless access points, CCTV cameras, printers, servers, NAS systems and other Ethernet-connected devices.

All 24 Ethernet ports are connected through the switch chip, allowing the device to operate as a high-density Layer 2 Gigabit switch.
2× 10G SFP+ Ports
For high-speed uplinks, the CSS326-24G-2S+RM includes two SFP+ cages. These ports can accept compatible 10G SFP+ modules as well as supported 1.25G SFP modules.
This makes it possible to connect the switch to a 10G aggregation switch, server, storage system, core switch or fiber backbone while using the 24 Gigabit ports for access devices.

| SFP+ Port 1 |
1.25G SFP / 10G SFP+ |
| SFP+ Port 2 |
1.25G SFP / 10G SFP+ |
The SFP+ cages can therefore be used for high-speed fiber uplinks or compatible copper transceiver connections.
SwOS Managed Switch
The MikroTik CSS326 runs SwOS, a lightweight operating system specifically designed for MikroTik switches.
SwOS is configured through a web browser and provides the management functions required for Layer 2 network switching.
Unlike the similarly named CRS326-24G-2S+RM, the CSS326 is a SwOS-only model. It should not be marketed as a RouterOS/SwOS dual-boot switch.
Layer 2 Switching Features
The CSS326 provides a range of managed-switch functions suitable for business and professional networks.
- IEEE 802.1Q VLAN
- Port isolation
- Port security
- Access Control Lists
- Broadcast storm control
- Port mirroring
- Bandwidth limitation
- Rapid Spanning Tree Protocol
- MAC-based forwarding control
- SNMP v1
- MikroTik neighbor discovery
- Web-based switch management
These features allow administrators to segment networks, control port access, monitor traffic and manage switching behavior without requiring a full Layer 3 routing platform.
VLAN Support
The MikroTik CSS326-24G-2S+RM supports IEEE 802.1Q VLAN functionality through SwOS.
VLANs can be used to separate different types of network traffic, such as office users, guest networks, IP phones, CCTV cameras, servers and management traffic.
The exact VLAN design should be planned according to the upstream router, firewall and network architecture.
Port Isolation and Port Security
Port isolation allows network administrators to control communication between connected Ethernet ports. This can be useful in environments where clients should communicate with a central gateway or server without directly communicating with other access ports.
Port security and MAC-based controls can also be used to restrict or manage access to specific switch interfaces.
Passive PoE-In
The CSS326 supports passive PoE input through Ethernet port 1. The current MikroTik documentation specifies a passive PoE input range of 11–30V DC.
The switch can alternatively be powered through its DC power jack, which also accepts 11–30V DC.
Important: this is PoE-in, not PoE-out. The CSS326 does not provide PoE power to connected Ethernet devices.

19W Maximum Power Consumption
MikroTik specifies maximum power consumption of approximately 19W for the CSS326-24G-2S+RM. Actual consumption depends on the operating conditions and connected modules.
The switch is therefore suitable for installations where a relatively low-power 24-port Gigabit switching platform with 10G uplinks is required.
Marvell Switch Chip
The CSS326 uses the Marvell 98DX3216A1 switch chip. The switching architecture provides non-blocking Layer 2 switching for the Ethernet interfaces.
The original MikroTik specification lists a 16K host table, providing substantial MAC address capacity for typical business and professional Layer 2 networks.
24-Port Switch for Business Networks
The combination of 24 Gigabit Ethernet ports and two 10G SFP+ uplinks makes the MikroTik CSS326 suitable for office networks where multiple wired devices need to connect to a higher-speed network backbone.
A typical deployment can use the 24 RJ45 ports for end devices and reserve the SFP+ ports for connections to an upstream core switch or aggregation layer.
CSS326 for CCTV Networks
The CSS326 can also be used as a Gigabit aggregation switch for IP surveillance networks where cameras are powered separately or through another PoE source.
Because the CSS326 itself does not provide PoE-out, PoE cameras require an external PoE switch, PoE injectors or another appropriate power source.
CSS326 for Server Rooms
In a server room, the CSS326 can provide 24 Gigabit Ethernet connections for servers, management interfaces, workstations and other network equipment, while its two SFP+ interfaces can provide 10G uplinks to the core or aggregation network.
This combination can help avoid using multiple low-speed uplinks when the access switch is connected to a higher-capacity network backbone.
Rackmount Installation
The CSS326-24G-2S+RM is designed for rackmount installation and uses a standard 1U form factor.
Its dimensions are approximately 443 × 144 × 44 mm. Rack ears are included for installation in a standard rack enclosure. It can also be placed on a desktop where appropriate.
Indoor Network Switch
The CSS326 is designed for indoor installation. MikroTik specifies an IPX0 rating, meaning the enclosure does not provide protection against water contamination.
The switch should therefore be installed in a dry, ventilated environment such as a network rack, server room, office or communications cabinet.
CSS326 vs CRS326
The product name should be checked carefully before purchase because MikroTik has both CSS326-24G-2S+RM and CRS326-24G-2S+RM models.

The CSS and CRS models should therefore not be treated as interchangeable simply because their port counts and names are similar. MikroTik’s current documentation explicitly identifies the CSS326 as SwOS-only.
