Mikrotik CRS504-4XQ-IN Cloud Router Switch 650MHz 4xQSFP28 Compatible with 40G 25G 10G and 1G Fiber Connections

Our 100 Gigabit family keeps expanding – you’ve already seen the incredible CCR2216 100 Gigabit router. Now it’s time for a matching switch – the CRS504-4XQ-IN. The small size combined with the low power consumption (25W without attachments!) is perfect to start expanding 100 Gigabit networking in everyday setups. This speed is no longer limited to data centers, ISPs, and large offices. You too can upgrade your 10 or 25 Gigabit network and join the one hundred club!.

There are four 100 Gigabit QSFP28 ports. Use them to connect other 100 Gigabit devices or grab a breakout cable to connect multiple 25 Gigabit devices: each port is connected to four 25 Gigabit lines, allowing you to connect 16 x 25 Gigabit devices. In fact, you can mix and match all kinds of connections this way: 100 Gigabits on one port, 40 Gigabits on the other, 4x25 Gigabits on the third, and maybe even some 10G or 1G cables on the fourth. The mighty Marvell DX4310 switch-chip will handle everything without breaking a sweat! 

Obviously, there is an Ethernet port for management purposes as well.

We’ve been using this switch for quite some time now in the Genomics Data Network project. A high-capacity data network for our local scientists working on ground-breaking cancer treatments. Genome data can take up a lot of space, so you need exceptionally fast connections there. Also, with these devices, Latvia became the first Baltic country to establish a 100 Gigabit connection to the pan-European research network

With multiple powering options and the ability to be mounted on the wall, this switch will make any system administrator happy.

Robust Internal Architecture

The switch is powered by the robust QCA9531 chipset, operating on a single core at 650 MHz, and supported by 64 MB of RAM. This combination ensures stable and reliable operation, essential for enterprises reliant on uninterrupted connectivity. Its 16 MB of storage capacity ensures the switch handles its firmware and updates efficiently. As technology and security needs evolve, this MikroTik switch remains current and secure. Equipped with RouterOS Level 5, the device boasts an array of networking capabilities, granting network administrators the flexibility to efficiently manage traffic, enforce security protocols, and optimize bandwidth distribution across diverse networking environments.

Adaptable Connection Options  

The CRS504-4XQ-IN stands out with its four 100G QSFP28 ports, allowing seamless connections to other 100 Gigabit devices. With the added advantage of breakout cables, you can connect to several 25 Gigabit devices. Essentially, each port 100G ties into four 25 Gigabit lines, giving you the capacity to connect up to 16 x 25 Gigabit devices. Whether you need a 100 Gigabit link on one port, a 40 Gigabit on another, or a combination of connections, the MikroTik CRS504-4XQ-IN provides the flexibility you’re seeking. Additionally, its Ethernet port serves as a handy tool for efficient management, providing easy access to the switch's main functions and simplifying diagnostics, configurations, and maintenance. 

Versatile Powering Options

The switch features a dual hot-swappable PSU, allowing for installation and removal while the server is running, without disrupting the server's functions. It also introduces versatile power options tailored to different scenarios:  

The conventional DC jack provides a familiar power interface for many, while the 2-pin terminal offers a more direct and robust connection, ideal for locations where ensuring stability is paramount. The advanced 802.3bt PoE-in stands out for its dual benefits: it not only powers the switch but also allows data transmission over a single cable, simplifying installations and reducing cable clutter. Such flexibility in power options ensures the switch can maintain continuous operation whether it's deployed in remote outdoor stations, temporary event setups, or critical infrastructure locations
