Network Switches

Types

• Unmanaged switch — plug-and-play with no configuration. Fine for small offices, labs and CCTV links.
• Smart or web-managed switch — basic VLANs and monitoring through a web page, at moderate complexity.
• Managed switch — full control: VLANs, QoS, security and monitoring. For larger organisations.
• PoE switch — powers IP cameras, Wi-Fi access points and phones over the network cable.
• Layer 3 or core switch — routes between VLANs and aggregates other switches in the building.
• Industrial switch — rugged, for factories and outdoor cabinets.

What to check before buying

• Number of ports and speed: gigabit is standard, with 10G uplinks for backbone links.
• PoE budget in watts, not just PoE support, so it can power all connected devices.
• Switching capacity, uplink ports (SFP or SFP+), and rack-mount or desktop form.
• Management features such as VLAN, port security and SNMP monitoring.
• Cabling quality and structured layout: Cat6 is a common choice for new installations.
• Warranty length, replacement terms, OEM authorisation and GST invoice.

Common brands include Cisco, TP-Link, D-Link, Netgear and HPE Aruba.

Who buys them

Offices, schools and colleges, hospitals, factories, hotels, CCTV installers, data rooms and government departments.

Frequently asked questions

How many ports do I need?

Count every device that needs a wired connection, then add 20 to 30 percent spare for growth. Choose 24 or 48 ports for larger floors.

Do I need PoE?

If you are installing IP cameras or ceiling Wi-Fi points, yes, as it avoids separate power cabling. Check the total PoE budget.

Managed or unmanaged?

Unmanaged suits a simple network. Choose managed if you need separate VLANs for guests, CCTV and staff, or want monitoring.
