Frequently Asked Questions (FAQ)
What is the difference between MikroTik CRS304-4XG-IN and CRS305-1G-4S+IN?
The main difference lies in the ports: The CRS304-4XG-IN offers four native 10GBASE-T (RJ45) multi-gigabit ports that utilize copper cables, while the CRS305-1G-4S+IN has four SFP+ ports designed for fiber optic connections or SFP+ transceivers. The CRS304 is ideal for pure copper 10G networks without additional modules.
Can the MikroTik CRS304-4XG-IN be used as a router?
The CRS304-4XG-IN can run RouterOS v7 and offers Layer 3 hardware offloading features, making it a capable managed Ethernet Switch with basic routing capabilities. However, it is primarily designed as an Ethernet Switch and not intended for extensive, high-throughput routing tasks, as the CPU is less powerful for such purposes.
Is the MikroTik CRS304-4XG-IN truly fanless and quiet?
Yes, the CRS304-4XG-IN is completely fanless. Its casing is designed as a massive heatsink that passively dissipates heat. This ensures completely silent operation, making it ideal for noise-sensitive environments.
What power supply options does the CRS304-4XG-IN offer?
The Ethernet Switch offers four redundant power supply options: two DC jacks, a 2-pin terminal, and PoE-In (802.3af/at) via the Gigabit management port. It automatically selects the power source with the highest voltage to ensure uninterrupted operation.
Does the MikroTik CRS304-4XG-IN support SwOS for easier management? (Niche)
Although official documentation indicates dual-boot with RouterOS v7 and SwOS, there have been user reports of difficulties or lack of compatibility when attempting to boot SwOS on this specific MikroTik Switch model. MikroTik has indicated that SwOS support is "upcoming" or works with certain RouterOS/SwOS versions, but practical implementation can be challenging.
Can the 1-Gigabit management port of the CRS304-4XG-IN be used for normal network traffic? (Niche)
Yes, the additional Gigabit Ethernet port can be used for both management purposes and PoE input. It can also be integrated into the bridge of the 10G ports. However, it should be noted that this port is on a separate switch chip and traffic is routed via the CPU, making it less ideal for high-performance data traffic than the dedicated 10G ports.
