Network Switches

A network switch, or ethernet switch, is a central device in a Local Area Network (LAN) that intelligently connects devices like computers, printers, and servers. Its primary role is to efficiently manage data packet forwarding. Many switches provide Power over Ethernet (PoE), delivering both data and power over one cable to devices such as network switch CCTV cameras. They are available in various sizes, from 4-port models to larger units, to suit different network scales.

Types of Network Switches

Switches are primarily defined by their configuration capabilities and environmental resilience, which determine their best-fit application.

Managed Network Switches

Managed switches offer complete control over network traffic, security, and performance. They enable advanced configurations like Virtual LANs (VLANs) and Quality of Service (QoS), making them essential for large, complex, or industrial networks requiring granular management and monitoring.

Unmanaged Network Switches

Unmanaged switches are plug-and-play devices with no user configuration needed. They automatically handle data traffic, making them ideal for small offices or non-critical applications where simplicity is key. A 4-port network switch is a common example.

Industrial Ethernet Switches

As explained in this IIoT guide, industrial ethernet switches are built for harsh environments and must withstand extreme temperatures, vibration, and electrical noise to connect modern factories. They feature rugged designs and redundant power inputs for high reliability in factories, outdoor installations, and critical infrastructure.

How to Choose the Right Network Switch

Selecting the right switch requires evaluating port density, device interoperability, management, and power needs.

Number of Ports - 4 Port Network Switch, 8-Port & More

Select a port count that accommodates all current devices and allows for future growth.

• 4/8-Port: Ideal for small-scale networks or connecting a few dedicated devices.
• 16/24/48-Port: Necessary for larger enterprise networks and comprehensive industrial control systems.

Device Compatibility

• Desktop Computers
• Printers
• Servers
• Game Consoles
• HD Drive Stations
• Smart TVs
• Laptops
• Routers

Confirm the switch supports the required ethernet standards (e.g., 10/100/1000 Mbps) of your end devices. This is crucial for specialised equipment like IP cameras or PLCs to ensure performance.

Network Management

Choose a managed switch if you need to control traffic, enhance security, or segment the network (VLANs). For basic, static networks, an unmanaged switch is sufficient and cost-effective.

Power over Ethernet (PoE)

If connecting powered devices like VoIP phones or CCTV cameras, select a PoE switch. Verify its power budget (total wattage) and per-port standard (e.g., 802.3af/at) can support all connected equipment.

Difference Between Network Switch vs Network Hub

Both hubs and switches look the same, but they operate slightly differently. Hubs are simpler devices, broadcasting all their information to all networking devices. They require less analysis and can, therefore, communicate quicker. Switches analyse the sender and receiver which can require more time but eliminates traffic congestion you may experience with Hubs. Hubs are ideal for small office and home environments while switches are better suited to small to large businesses which require more advanced network equipment.

Mistakes to Avoid When Buying Network Switches

Wrong Type: Do not use unmanaged switches for complex networks or over-specify managed switches for simple setups.

• Forgetting PoE: Overlooking PoE for compatible devices adds unnecessary cost and cabling complexity.
• No Scalability: Selecting a switch with no spare ports hinders future network expansion.
• Ignoring Environment: Deploying a standard network ethernet switch in a harsh industrial setting will result in equipment failure.

Common Uses & Applications

CCTV and Surveillance Systems

PoE switches are fundamental for powering and connecting IP cameras and recorders, streamlining installation. An industrial network switch ensures operational reliability in outdoor or challenging environments.

Office Networking

Switches are the backbone of office LANs, acting as the primary switch for networking computers, printers, and servers. Managed switches can prioritise critical traffic (like VoIP) and improve security through network segmentation.
