Overview

UniFi Switches — PoE Switching Supplied and Configured in the UK

The switch is what actually powers a UniFi network — access points, cameras and door readers all draw from it. We size the PoE budget and uplinks properly so the estate still has room when you add the next ten devices.

Picking the right UniFi switch

Port count is the easy part. The figures that catch people out are total PoE watts and uplink capacity — a fully loaded 24-port switch feeding access points and cameras can run out of power long before it runs out of ports.

  • 8 and 16 port — small offices, back rooms and satellite cabinets
  • 24 port — the standard floor switch for most offices
  • 48 port — larger floors and comms rooms, usually with SFP+ uplinks
  • Aggregation models where multiple switches feed back to a core

PoE budget done properly

We add up what every connected device draws, allow headroom for growth, and confirm whether you need PoE, PoE+ or PoE++ ports rather than assuming the highest tier everywhere.

  • Device-by-device power draw totalled against the switch budget
  • PoE, PoE+ and PoE++ port mix matched to the kit being powered
  • Fibre or 10G uplinks where floors aggregate back to a core
  • Spare capacity planned so the next expansion does not need a new switch

Configured before it reaches you

VLANs, port profiles and uplinks can all be set before dispatch, adopted into your existing console, so installation is a rack-and-patch job.

  • VLANs and port profiles pre-configured
  • Adopted into your existing UniFi console
  • Genuine UK stock, warranty and RMA handled by us

FAQs

Questions We Are Asked Most

Do I need a managed switch for UniFi access points?

Not strictly — an access point will work on any PoE port. But a UniFi switch puts port control, VLANs and power cycling in the same console as everything else, which is why most estates use one.

What is the difference between PoE and PoE+?

PoE (802.3af) supplies up to about 15W per port, PoE+ (802.3at) up to about 30W. Older access points and cameras run on PoE; newer higher-power models need PoE+.

Can UniFi switches work with non-Ubiquiti hardware?

Yes. They are standard managed switches and will power and connect any compliant device — you simply manage third-party kit outside the UniFi console.
