Network Switches

A network switch serves as a vital central hub, connecting various devices like computers and printers to create a seamless local network.

For example, with an Ethernet network switch, you can easily share data and internet access across multiple platforms in homes, schools, or offices.

These units feature several ports for Ethernet cables, with some models supporting Power over Ethernet (PoE) to power devices like CCTV cameras directly.

RS New Zealand offers an extensive range of data switches, from compact 4-port models to high-capacity 48-port enterprise solutions, ensuring reliable connectivity for any scale.

Types of Network Switches

Various types of networking switches are available to provide optimal data flow and security across different technical requirements.

Managed / Smart Switches

These highly customisable data switches offer advanced control over network configurations and traffic prioritisation. Featuring a dedicated user interface, they are perfect for large businesses needing to manage security and complex data transfers.

Unmanaged Switches

The simplest networking switch option, these function as plug-and-play devices requiring no user configuration. They are ideal for home offices where basic, reliable connectivity is the priority over granular network control.

LAN / Active Hubs

This type of internet switch automatically manages traffic by broadcasting data to all connected devices. While simpler than managed options, they efficiently prioritise signals according to current requirements for smaller, independent networks.

Industrial Applications of Network Switches

Ethernet network switches are a foundational component in modern connectivity, facilitating efficient communication across various commercial, industrial, and residential environments.

• Offices: From small local businesses to massive global enterprises, Ethernet switches are crucial to link devices like workstations, printers, and VoIP phones. This ensures seamless collaboration and reliable access to shared company databases across NZ and internationally.
• Data Centres: High-performance data switches manage vast amounts of traffic between servers and storage arrays. These units are critical for maintaining the high-speed throughput required for cloud computing and large-scale hosting.
• Manufacturing Facilities: In smart factories, network switches connect programmable logic controllers, robotic arms, sensors, and cameras. This integration allows for real-time monitoring and synchronised automation across the entire production floor.
• Transportation Systems: Reliable networking switches facilitate communication in rail and traffic management systems. They manage data from signalling sensors and passenger information displays to ensure safe and efficient transit operations.
• Oil and Gas: Operating in harsh environments, specialised network switches monitor remote drilling telemetry and pipeline sensors. This connectivity is vital for maintaining operational safety and coordinating complex extraction processes across vast distances.
• Surveillance and Security: Network power switches with PoE capabilities simplify the installation of IP cameras and access control systems. This allows data and electricity to travel over a single cable.
• Home Networks: Internet switches connect devices, such as gaming consoles, smart TVs, and automated lighting systems, in modern smart homes. This creates a robust backbone that supports high-bandwidth streaming and integrated home control.

Factors to Consider When Choosing a Networking Switch

To select a suitable network switch, evaluate the following considerations to ensure your hardware effectively supports your data traffic and connectivity goals.

• Network size: Your total device count determines the required port density. Ensure your Ethernet switch has enough inputs for all current computers and peripherals.
• Speed and bandwidth: Consider your use needs to avoid bottlenecks. For example, a Fast Ethernet speed would be sufficient for simple web browsing, but if you foresee high-bandwidth tasks like large file transfers and streaming, Gigabit might be more suitable.
• Management needs: Decide if you require a managed network switch for granular control or a simple unmanaged version for basic, maintenance-free connectivity.
• PoE support needs: Determine if you need a PoE switch to power devices like VoIP phones directly. Alternatively, a PoE injector can provide power to non-PoE switches.
• Options for scaling: Consider future growth by choosing data switches that allow for stacking or additional uplink ports to expand your network capacity easily.
• Budget: Balancing performance with cost is essential. Assess the long-term value of advanced features against the initial investment for your internet switch.

Frequently Asked Questions About Network Switches

What kind of devices can I connect to a network switch?

You can connect various hardware to a network switch, such as:

• Desktop computers
• Laptops
• Printers
• Servers
• Smart TVs
• Game consoles
• Routers
• HD Drive Stations

This enables you to achieve a stable, high-speed wired connection across your devices, all on a single, unified network.

What is the difference between a network switch and network hub?

While they look similar, network hubs are simpler than network switches. Hubs broadcast data faster to every connected device, which can cause congestion.

Meanwhile, network switches identify specific senders and receivers, directing traffic intelligently. While they require more time to communicate, they reduce interference, making them preferred for environments with advanced, high-traffic networking.

What does “PoE” mean? When should I pick a PoE switch?

PoE stands for “Power over Ethernet,” a technology that allows a single cable to transmit both data and electricity.

You should choose this type of network power switch when installing devices like IP cameras or VoIP phones in locations where dedicated power outlets are unavailable or impractical.

How many devices can a network switch support?

A network switch can support anywhere from four devices for home use to thousands in enterprise data centres. This scalability allows users to choose a specific port density that matches their current connectivity requirements and future growth plans.

What’s the difference between Layer‑2 and Layer‑3 switches?

Layer-2 switches forward data within a local network using MAC addresses for simple connectivity.

In contrast, Layer-3 units combine Layer-2 switching with routing capabilities, using IP addresses to manage and move data packets between different networks.

Can I just add more network switches later if I need more ports?

Yes, you can expand your port count by connecting additional networking switches to your existing setup.

However, be mindful of over-stacking units, as too many layers may reduce data speeds and complicate network management.
