## Summary description

The MikroTik CRS504-4XQ-IN is a managed L3 switch featuring 1 Fast Ethernet port and Power over Ethernet (PoE) support. It operates on a DC input voltage of 36 - 57 V and complies with IEEE 802.3bt standards. This 1U rack-mountable switch is designed for efficient networking, providing reliable performance and flexibility for various applications.

## Long description

The MikroTik CRS504-4XQ-IN is a compact managed L3 switch with four QSFP28 ports delivering 100 Gigabit connectivity and one Fast Ethernet management port. Designed for low power consumption (about 25 W without attachments) and multiple powering options, the unit supports rack mounting and wall installation. Its Marvell DX4310 switch chip enables flexible port configurations, including breakouts to 25 Gbit lanes and mixed-speed deployments.
Advantages
The switch provides four 100 Gigabit QSFP28 ports that can each be split into four 25 Gbit lanes, allowing up to 16 separate 25 Gbit connections; ports may also be used for 100G, 40G, 10G or 1G links as needed. A dedicated Fast Ethernet RJ-45 port is available for management. The device is energy-efficient, compact, and uses a proven Marvell DX4310 chip for stable high-capacity switching. It supports IEEE 802.3bt and offers PoE-capable infrastructure compatibility as part of flexible deployment options.
Suitable for (tasks / use cases)
Upgrading campus or lab networks from 10/25G to 100G backbones
High-throughput research or genomics data networks
Mixed-speed aggregation switches in ISP or enterprise edge deployments
Small rack or wall-mounted installations where low power consumption is important

How to use
Install the CRS504-4XQ-IN in a rack or mount it on a wall and connect a suitable DC power source in the 36–57 V range. Use QSFP28 modules or breakout cables to connect 100G or multiple 25G endpoints; standard SFP+/SFP28 transceivers or DAC/active cables are supported via appropriate adapters or breakout assemblies. Connect the Fast Ethernet RJ-45 port to your management network to access the MikroTik management interface for configuration, routing, VLANs and L3 policies. Follow standard safety practices when handling optical modules and powering network equipment.
Usage recommendations
For mixed-speed deployments, plan port mapping in advance (which QSFP28 ports will host 100G, 40G, or 4×25G) and ensure compatible transceivers or breakouts are used. Verify power source compatibility with the device’s DC input range and consider proper ventilation in confined installations.
