MikroTik CRS326-4C+20G+2Q+RM 20×2.5G Ethernet Switch
The MikroTik CRS326-4C+20G+2Q+RM is a high-density rack-mounted switch designed for environments where 2.5 Gigabit connectivity is essential, such as offices, studios, and professional environments transitioning to multi-gigabit speeds. It delivers 20 × 2.5G Ethernet ports, 4 × Combo ports (2.5G Ethernet or 10G SFP+), 2 × 40G QSFP+ uplink ports, a dedicated 100 Mbps management port, and dual-redundant hot-swap power supplies. Running both RouterOS v7 and SwitchOS, it combines powerful Layer 2/Layer 3 switching with flexible management options.

The MikroTik CRS326-4C+20G+2Q+RM is a rack-mounted multi-gigabit switch built around the Marvell Prestera 98DX8332 switch chip, paired with a QCA9531 MIPSBE CPU running at 650 MHz, 128 MB of RAM, and 32 MB of FLASH storage. It is designed to meet the growing demand for 2.5 Gigabit Ethernet port density in professional environments — including offices, studios, and similar settings where high-bandwidth client connectivity is a priority.
The port configuration centres on 20 × 2.5G Ethernet ports, complemented by 4 × Combo ports that can function as either 2.5G Ethernet or 10G SFP+ depending on what is connected. Two 40G QSFP+ ports provide high-speed uplink capacity for connecting to core switches or aggregation layers. An additional dedicated 100 Mbps Ethernet management port is included for out-of-band management, ensuring switch administration is isolated from production traffic. A serial console port (RJ45) is also available.
Reliability is addressed through dual-redundant hot-swap power supplies housed in two PSU slots, allowing a failed PSU to be replaced without interrupting switch operation. Active cooling is provided by two fans. The device accepts AC input of 100–240 V at 50–60 Hz, with maximum power consumption of 70 W (51 W without attachments).
The switch supports both RouterOS v7 and SwitchOS, giving operators the choice of full RouterOS feature depth — including hardware-accelerated Layer 3 routing (L3HW), ACLs, VLANs, and advanced traffic management — or the streamlined SwitchOS interface. PCB temperature and voltage monitoring are built in. RouterOS v7 is pre-installed and licensed — no separate purchase is required.
The unit ships with 2× IEC cords, rackmount ears, and a screw and feet kit (K10).
