Compatible 10G SFP+ and DAC Cable For MikroTik CRS305-1G-4S+ 10G Ethernet Switch
Sep
If you want to buy an Ethernet switch, the MikroTik CRS305-1G-4S+ 10G Ethernet Switch is a good choice at a low price. It is a desktop switch with four SFP+ ports and a 1 Gbit copper Ethernet port. Each SFP+ port can reach 10 Gbit. It helps your network operate more efficiently.
Although it’s small in size, its functions are potent. In this blog, we will introduce the MikroTik CRS305-1G-4S+10G Ethernet Switch to you with features, disadvantages, and application scenarios. At the same time, we will introduce our compatible 10G SFP+ module and DAC cable.
Features of MikroTik CRS305-1G-4S+ 10G Ethernet Switch
1. Fanless design
The CRS305-1G-4S+ 10G Ethernet Switch is passively cooled. It uses a fanless design, so it does not make any noise when it is running. This design enables the CRS305-1G-4S+ 10G Ethernet Switch to be applied in noise-sensitive environments, such as the home, offices, schools, libraries, and so on.
2. Dual boot
This device is equipped with a dual boot so that you can choose between the RouterOS and SwOS operating systems. You can choose to use SwOS when you want to use a simplified system. You can choose to use RouterOS when you wish to use other functions. By simply restarting this device, you can switch it freely between a fully functional router and a pure line-speed switch.
3. PoE input
The CRS305-1G-4S+ 10G Ethernet Switch contains a PoE input. So you can supply power from the PoE input, which can significantly reduce the number of cables. At the same time, this also makes the installation location of the device flexible, allowing it to be deployed even in areas without power sockets.
4. Two DC jacks
This switch features two DC jacks, providing power redundancy. It provides a backup power supply path for the device, which can automatically switch when the main power supply fails. It also prevents the device from losing power, ensuring continuous operation and reducing the risk of data loss and hardware damage.
Disadvantages of MikroTik CRS305-1G-4S+ 10G Ethernet Switch
1. Poor heat dissipation
Due to its fanless design, this switch has difficulty dissipating heat. We saw that many customers have complained about this problem. This device may overheat in poorly ventilated environments, which can affect its stability and shorten its service life. Its temperature can even reach 85 degrees Celsius.
To solve this problem, you may have to purchase a radiator additionally. Moreover, you should pay attention to the warning sign and be careful not to touch it or splash water into it when it is running.
2. Poor performance
Some customers complained about its performance. After our tests, we found that as long as we connect through the switch, we are restricted, and it even exhibits strange behaviors. Some said that there is something that chokes Mikrotik when routing data to a computer. In addition, they found that when running with RouterOS, excessive CPU load could easily lead to packet loss.
Applicable Scenarios of MikroTik CRS305-1G-4S+
The CRS305 is compact in size and features low power consumption. Therefore, it is a suitable choice for customers who want to switch but lack sufficient power or space to deploy this device.
Due to its silent design, this device operates noiselessly, making it suitable for individuals or environments sensitive to noise. You can place it anywhere, such as at home, at school, in the office, in the studio, and so on. Whenever you are working or taking a nap, it seems as if it does not exist and will never disturb you.
Meanwhile, its favorable price makes it suitable for customers with a lower budget. You can buy a small switch for just $149, and it can be even lower if there are discounts. Although it still has some disadvantages, it is already very cost-effective at this price level.
