MikroTik CRS304-4XG-IN
Please contact us for stocking information.
The CRS304-4XG-IN is a compact 10 Gigabit Ethernet switch that is highly efficient and simplifies the setup of your network. It comes with four built-in 10 Gigabit Ethernet ports, eliminating the need for additional SFP modules and allowing for a plug-and-play setup. To manage the switch, there is also a Gigabit Ethernet port included.
With a fanless design, the CRS304 utilises its enclosure as a heat sink, providing silent operation, making it suitable for noise-sensitive environments such as offices or home labs. Its sturdy yet lightweight build offers both durability and a premium feel, all at an affordable price.
The CRS304 can be easily integrated into any setup with its versatile mounting options, such as a side DIN rail mount and standard screw attachments. Redundancy is supported through multiple power input options, including two DC jacks, a 2-pin terminal, and PoE-in, with automatic power source selection for reliability. Equipped with a dual-core ARM
