MikroTik CRS326-24S+2Q+RM 24-Port 10G SFP+ & 40G QSFP+ Managed Switch
The MikroTik CRS326-24S+2Q+RM is a high-density fiber aggregation switch designed for data centers, enterprise networks, ISP infrastructure, server clusters and high-speed network backbones. It combines 24 × 10G SFP+ ports with 2 × 40G QSFP+ ports in a professional 1U rackmount enclosure.
The CRS326-24S+2Q+RM is designed for networks handling substantial amounts of data. Its 24 SFP+ interfaces provide high-density 10Gbps connectivity, while the two QSFP+ interfaces provide 40Gbps connections for high-speed uplinks, inter-switch links and aggregation. MikroTik specifies up to 320Gbps non-blocking throughput and 640Gbps switching capacity.
24× 10G SFP+ Ports
The CRS326-24S+2Q+RM provides 24 dedicated 10G SFP+ ports for high-speed fiber and direct-attach connectivity.
These interfaces can be used with compatible SFP+ optical transceivers, fiber modules, DAC cables and active optical cables depending on the network design and required distance.
- 24 × 10G SFP+ ports
- 10Gbps fiber connectivity
- Compatible SFP/SFP+ modules
- 10G DAC connectivity for suitable short-distance links
- AOC connectivity with compatible active optical cables
- High-density 10G server and aggregation connectivity
The 24-port SFP+ design makes the CRS326 suitable for environments where a large number of servers, switches, storage systems or network devices require 10Gbps connectivity.
2× 40G QSFP+ Uplink Ports
In addition to its 24 × 10G SFP+ interfaces, the CRS326 includes 2 × 40G QSFP+ ports. These interfaces provide higher-bandwidth connectivity for network aggregation and backbone applications.
The QSFP+ ports can be used for compatible 40Gbps connections between switches, routers, servers or other high-speed network equipment. They are particularly useful when the 10G access layer needs to connect to a higher-capacity aggregation or backbone layer.
Depending on the supported transceiver or cable, QSFP+ connectivity can also be used in appropriate breakout configurations. The exact breakout capability depends on the compatible module, cable and connected equipment.
320Gbps Non-Blocking Throughput
The CRS326-24S+2Q+RM is designed as a high-capacity switching platform. MikroTik specifies 320Gbps total non-blocking Layer 1 throughput and 640Gbps switching capacity.
The manufacturer also specifies a forwarding rate of approximately 252 million packets per second (Mpps) with common packet sizes. These are manufacturer test results under specified conditions and should not be interpreted as guaranteed application throughput for every network configuration.
Marvell Prestera 98DX8332 Switch Chip
The CRS326-24S+2Q+RM uses the Marvell Prestera 98DX8332 switch chipset. The hardware architecture is designed for high-speed Layer 2 switching across the 10G SFP+ and 40G QSFP+ interfaces.
MikroTik’s current documentation identifies the 98DX8332 as the switch chip used in this model and provides hardware-offloading capabilities for supported Layer 2 and Layer 3 functions.
RouterOS and SwOS Dual Boot
The CRS326-24S+2Q+RM supports both RouterOS and SwOS. This dual-boot design allows the switch to be used according to the requirements of the network.
SwOS provides a dedicated switch-management environment focused on Layer 2 operation, while RouterOS provides broader routing and networking functionality. The current MikroTik documentation confirms that both operating systems are supported.
Hardware-Based VLAN and Layer 2 Switching
The CRS326 is designed for professional Layer 2 switching and supports hardware-based processing for supported switching functions.
- IEEE 802.1Q VLAN
- VLAN filtering
- Port isolation
- Link aggregation
- LACP
- Spanning Tree Protocol
- Rapid Spanning Tree Protocol
- Multiple Spanning Tree Protocol
- Access Control Lists
- Port mirroring
- IGMP Snooping
- Broadcast storm control
- Bandwidth management
The CRS326 family is also included in MikroTik’s documentation for hardware-offloaded routing and switching features.
10G Server and Storage Aggregation
With 24 high-speed SFP+ ports, the CRS326-24S+2Q+RM can be used as a central aggregation switch for 10Gbps servers and storage systems.
Typical deployments can include virtualization hosts, NAS systems, storage arrays, backup servers, database infrastructure and high-performance computing equipment. The 40G QSFP+ ports can then provide higher-speed uplinks toward the network backbone.
40G Backbone Connectivity
The two QSFP+ ports make the CRS326 particularly useful in network architectures where 10G access links need to aggregate into a 40G backbone.
A typical topology can use the 24 SFP+ ports for 10G server or access connections and the QSFP+ interfaces for 40G connections toward an upstream aggregation switch or another CRS326.
1U Rackmount Design
The CRS326-24S+2Q+RM is designed for installation in a standard 1U network rack. Its chassis measures approximately 443 × 200 × 44 mm.
Rack ears are included, making the switch suitable for professional network cabinets, server racks and data-center infrastructure. MikroTik’s current documentation identifies this device as intended for rackmount installation and indoor use.
Dual Redundant AC Power
The CRS326-24S+2Q+RM has two AC power inputs and two PSU slots, providing power redundancy for professional deployments.
The supported AC input range is 100–240V AC. MikroTik specifies maximum power consumption of up to 69W with attachments, while the current documentation lists approximately 42W without attachments.
Using redundant power supplies can help improve network availability when one power source or PSU becomes unavailable.
USB Type-A and RJ45 Console
The CRS326 includes a USB Type-A port and an RJ45 serial console port. The USB port can be used with supported peripherals and RouterOS functions, while the serial console provides an additional method for configuration and recovery.
The USB interface supports up to 1A current according to MikroTik’s published specifications.
Dedicated 10/100 Management Ethernet
The CRS326-24S+2Q+RM includes one 10/100 Ethernet RJ45 port. This is intended primarily for management connectivity and should not be confused with a Gigabit Ethernet management port.
The primary high-speed data interfaces of the device are the 24 × 10G SFP+ and 2 × 40G QSFP+ ports.
Layer 3 Hardware Offloading
When RouterOS is used, the CRS326 can utilize supported hardware-offloaded Layer 3 functions. MikroTik’s current hardware-offloading documentation lists the CRS326-24S+2Q+RM with the Marvell 98DX8332 switch chip and specifies hardware resources for IPv4 and IPv6 routes, hosts and NAT entries.
However, the CRS326 is primarily a high-capacity switching platform. RouterOS CPU-based routing performance is substantially lower than its wire-speed Layer 2 switching capability, so network designs should distinguish between hardware-offloaded switching and CPU-processed routing workloads.
Professional Network Applications
The combination of 24 × 10G SFP+, 2 × 40G QSFP+, hardware switching and redundant power makes the CRS326-24S+2Q+RM suitable for demanding network environments.
