Ethernet switches are network devices used for data exchange and transmission, typically deployed in enterprise backbone networks, data centers, and server rooms to support high bandwidth requirements. But do you really understand OEM Ethernet switches? What are their functions? This article will provide you with detailed answers.

The functions and main features of Ethernet switches

As mentioned above, Ethernet switches are network devices that implement data transmission and exchange based on Ethernet. So, what are their main characteristics?

1. Provide network interfaces for interconnection: The main function of data center Ethernet switches in network systems is to provide network interfaces for interconnection between networked devices.

2. Expanding network interfaces: Typically, an Ethernet switch can have up to 48 ports, and in high network demand situations, Ethernet switches can be stacked to meet network requirements.

3. Expand network scope: Ethernet switches use transmission media to connect to networked devices, and the transmission distance of each transmission medium is different and limited depending on the networking technology used. When the network coverage is large, Ethernet switches can perform relaying, exponentially expanding transmission distance and increasing network coverage.

4. Ethernet switch learning function: Ethernet switches can learn the MAC address of devices connected to each port, map the MAC address to the corresponding port, and store it in the switch's MAC address table cache.

5. Ethernet switch forwarding/filtering function: When the destination address of a data frame is mapped in the MAC address table, it will be forwarded to the port connected to the destination.

6. Ethernet switch loop elimination function: When an Ethernet switch includes redundant loops, it can avoid creating loops through the spanning tree protocol and allow backup paths.

Precautions for using Ethernet switches

To ensure that Ethernet switches, a type of network switch OEM, work properly and last for a long time, please note the following:

1. Place the Ethernet switch in a well ventilated, dry, dust-free, and low electromagnetic interference area;

When placing an Ethernet switch, please ensure its stability to avoid unnecessary losses caused by dropping;

3. Leave enough space around the Ethernet switch for normal heat dissipation;

4. Do not place heavy objects on Ethernet switches;

5. Ensure that the Ethernet switch is grounded during use;

6. The power supply voltage of the power cord must comply with the input voltage range of the switch to ensure appropriate power supply.

Conclusion

With the continuous improvement of performance and the continuous reduction of cost, Ethernet switches have been widely used in enterprise networks and data centers.
