Network Switch is an important device in a network system. It functions to connect various devices within the network, such as computers, access points, IP phones, CCTV cameras, NAS, servers, and IoT devices, enabling them to communicate and transmit data efficiently.
Nowadays, a switch is not just a device for “adding LAN ports,” but also plays an important role in network management, such as separating VLANs, controlling traffic, providing PoE power to Access Points or IP Cameras, connecting high-speed uplinks, and managing through a controller or cloud system.
This article will explain the types of Network Switches based on their usage, along with guidelines for choosing a Switch suitable for homes, home offices, businesses, and organizations, using TP-Link Omada as an example. It is a network system commonly used in shops, restaurants, offices, hotels, schools, multi-story buildings, and businesses that require centralized network device management.
What is a Network Switch?
Network Switch is a device used to connect multiple devices in a LAN network together. The switch learns which device is on which port through the MAC Address and then sends data to the correct destination port, making data transmission more efficient and reducing data collisions on the network.
Examples of devices that are often connected to a Switch include
- Computers and Notebooks
- Access Points for Wi-Fi
- IP Cameras or CCTVs
- IP Phones
- NAS and Servers
- Printers
- Gateways or Routers
- Controllers or Network Management Devices
Why is choosing the right switch important?
If an inappropriate switch is chosen for the task, it may cause the network system to be slow and unstable, cameras or access points may not have enough power, the Wi-Fi system may not operate at full performance, or it may be difficult to expand the system in the future.
Things to consider before choosing a Switch include
- Number of ports required
- Port speed, such as 1GbE, 2.5GbE, 10GbE, or 25GbE
- Need PoE, PoE+, or PoE++?
- Number of Access Points, IP Cameras, or IP Phones
- Need VLAN to separate networks?
- Need to manage through Omada Controller?
- Is there an uplink to Gateway, NAS, Server, or main Switch that requires high speed?
- Need fiber connection between Rack cabinets, between floors, or between buildings?
- Need a system that can expand in the future?
