MikroTik Cloud Core Router, 4x 100GB QSFP28, PoE in, 2 reductive power supplies Ethernet router (CRS504-4XQ-IN)
The CRS504-4XQ-IN Cloud Core Router from MikroTik is a compact, high-performance 100G Ethernet device designed for modern data centers, service providers, and demanding enterprise networks. Equipped with 4× 100G QSFP28 ports, PoE-in support, and 2 redundant power supplies, this router offers exceptional flexibility and reliability in a small, energy-efficient form factor. It is ideal for aggregation, backbone routing, and high-speed interconnects between servers, switches, or core network segments.
Technically, the CRS504-4XQ-IN provides four QSFP28 cages that each support 100 Gigabit Ethernet connectivity, enabling up to 400 Gbit/s total switching capacity. The device supports various 100G transceivers and DAC cables (depending on the module used), allowing adaptation to both short- and longer-distance links. Redundant power supplies increase operational reliability: if one power source fails, the second continues to supply the router, reducing downtime and supporting business-critical operations. The PoE-in option (e.g., via a compatible port or injector according to MikroTik's specifications) allows the device to be powered conveniently without separate AC connections in some scenarios, making it easier to deploy in constrained environments such as edge racks, small PoPs, or lab setups.
In terms of applications, the CRS504-4XQ-IN is particularly suitable as a 100G aggregation router or switch in ISP and WISP infrastructures, where it can consolidate multiple 10/25/40G access or distribution devices into a 100G core. It is also well-suited for high-speed connections in data centers, for example between server clusters and storage systems, or as an uplink device in enterprise campus environments that are transitioning to 100G. Thanks to MikroTik's operating system and feature set (such as routing, VLANs, traffic management, and monitoring functions, depending on the configuration and license), the device can be integrated flexibly into both L2 and L3 network designs.
The advantages of this product include its very high port density relative to its physical size, which saves rack space and simplifies cabling in dense environments. Redundant power supplies and PoE-in options provide multiple powering strategies, contributing to higher availability and easier deployment. The use of 100G QSFP28 interfaces helps organizations prepare for future bandwidth demands while maintaining compatibility with widely available 100G optics and cables. Its fan and power design is generally optimized for energy-efficient operation for its performance class, which can help lower running costs and reduce heat in the rack.
MikroTik, as the manufacturer, is known globally for networking equipment that offers a strong price-performance ratio and a wide feature set. The company focuses on providing reliable, flexible routers and switches that can be used by both service providers and enterprises. MikroTik invests in robust software updates and long-term support for products, helping customers extend the useful life of their hardware. This in turn supports more sustainable IT: devices can remain in operation longer, be repurposed for other roles, or be scaled within an existing network, instead of being replaced prematurely.
From a sustainability perspective, MikroTik's emphasis on compact, efficient designs can contribute to reduced energy consumption and lower cooling requirements in network environments compared to bulkier, less efficient equipment of similar capability. By integrating high bandwidth in a small chassis and supporting flexible deployment scenarios, the CRS504-4XQ-IN can help consolidate multiple legacy devices into a single, more efficient platform, which may reduce the total number of powered devices in a rack. As a customer, choosing hardware that combines high performance with efficient operation and long product life allows you to contribute to lower resource usage and waste in your IT infrastructure, which is a meaningful step toward more responsible technology deployment.
