Most small and medium businesses in Johannesburg still run on consumer-grade networking. That's fine until it isn't: when load shedding knocks out your router, when a single cable failure takes down half your office, or when you realise your WiFi won't reach the back room. That's where UniFi switches come in.
We're writing this because we install UniFi switches regularly, we troubleshoot them when others have made a mess of the setup, and we've seen first-hand what works and what doesn't in Johannesburg's climate and infrastructure environment.
What a UniFi Switch Actually Does (and Why It Matters)
A managed UniFi switch isn't just a box with ports. It's the nervous system of your network.
Consumer switches? They're passive. Plug in cables, traffic flows, that's it. A UniFi switch is active: it learns which devices are on which ports, it prioritises video calls over background updates, it isolates network problems before they spread, and it gives you visibility into exactly what's happening on your network in real time.
For Johannesburg businesses dealing with load shedding and load shifting, this matters even more. When power fluctuates, a managed switch with proper configuration and UPS backup keeps your most critical systems running. We've installed UniFi switches in offices where a single power dip used to bring down the entire network for an hour. After proper installation and configuration, those same offices experience seamless failover.
The UniFi platform—made by Ubiquiti—also scales. Start with an 8-port switch in your office. A year later, add a 24-port switch in your new location and manage both from a single dashboard. That scalability is something we see clients value heavily once they've experienced it.
UniFi Switch Installation: What We Actually Do in Hyde Park
Installation isn't complicated, but doing it *properly* takes knowledge we've accumulated across more than 12,000 devices serviced in the Johannesburg area.
Start with assessment. We visit your site—whether that's Midrand, Bryanston, or the CBD—and understand your current setup. How many devices? What's your cabling situation? Is your server room secure? What's your power situation during load shedding? We charge R599 for this assessment, which covers a full site survey and a written recommendations report. Most clients find this clarifies their entire network picture.
From there, installation typically involves:
Cabling verification. Ninety per cent of network problems we inherit from other installers trace back to cabling. We audit existing cables, replace anything sub-standard, and test every cable run before we connect the switch.
Switch placement. Managed switches generate heat. In Johannesburg's summer—even with air conditioning—proper ventilation matters. We place switches in server racks with airflow, never in cupboards or enclosed spaces.
Power and redundancy. We configure UPS backup for your switch. During load shedding, your switch stays alive long enough for devices to maintain critical connections. We can discuss unmanaged failover or managed failover depending on your setup.
Configuration and management. We set up your UniFi controller—either cloud-hosted or local—and configure VLANs, traffic rules, and monitoring. This is where the real value happens: once your switch is running, you can see your network. You know which devices are consuming bandwidth. You know when a device stops responding. You can prioritise video conferencing over casual browsing.
Documentation. We leave you with a physical network diagram, a list of all devices, port assignments, and clear instructions for adding new devices.
Installation typically takes a half-day for small setups (under 20 devices) and a full day for larger installations. We include three years of support at no extra cost—if something breaks or stops working, we fix it.
UniFi Switch Models for Johannesburg Businesses
We install several UniFi models depending on business size and budget.
The UniFi Switch 8 works for small offices: eight ports, compact, affordable. We've deployed these in professional services firms across Rosebank and Illovo.
The UniFi Switch 16 handles medium offices: sixteen ports, still compact, more flexibility.
The UniFi Switch 24 is our most common installation. Twenty-four ports, PoE capability (meaning it can power WiFi access points and IP cameras directly), proper management features, and enough headroom to grow. Most Johannesburg offices we work with start here.
For larger setups—law firms, media agencies, tech companies—we design multi-switch environments where one core switch sits in the server room and secondary switches in different areas feed back to it.
Pricing varies. A basic 8-port switch costs less than R3,000. A 24-port PoE switch runs R8,000–R10,000. Installation, configuration, and three years of support typically add R2,500–R5,000 depending on complexity.
Common Installation Mistakes We See
We inherit installs from other providers regularly. These are the patterns we notice.
Poor cabling. The cheapest cables fail first, especially in Johannesburg where temperature swings can stress connections. We use proper CAT6A cabling throughout.
No PoE planning. If your plan includes IP cameras or wireless access points, you need PoE (Power over Ethernet). Installing a non-PoE switch, then later adding those devices, means running separate power cables. We plan PoE into the design from day one.
Inadequate power backup. A UPS that's too small means your switch shuts down after five minutes of load shedding, just as the outage starts. We size UPS systems for your actual load, not a guess.
No VLAN separation. A switch gives you the capability to separate guest WiFi from business traffic, or accounting systems from general browsing. Most installers don't configure this. We do, because security matters.
Switch overheating. Cramming a switch into a cupboard with no ventilation, then wondering why it restarts randomly. We verify temperature and airflow before we finish.
If you've experienced any of these—or if you're simply uncertain whether your current network is set up properly—that R599 assessment we mentioned earlier usually reveals the gaps. Most clients find it clarifies their entire situation.

Frequently Asked Questions
Q: How long does a UniFi switch installation take?
Small offices (eight devices or fewer) typically take two to four hours. Medium offices (fifteen to thirty devices) take one full day. Larger deployments may take two days. We schedule around your business hours—most installations happen early morning or after 5 p.m. to minimise disruption.
Q: Do I need a server to run a UniFi switch?
No. UniFi switches work with a cloud-based controller (free Ubiquiti account) or a local controller device (a small computer, often included). You don't need an expensive server. For most Johannesburg businesses, the cloud controller works perfectly.
Q: What's the difference between PoE and non-PoE switches?
PoE means Power over Ethernet—the switch sends electrical power down the same cable that carries data. This lets you power wireless access points and IP cameras without running separate power cables to each device. For modern network design, PoE is worth the extra cost.
Q: How much does UniFi switch installation cost?
Assessment costs R599. The switch itself ranges from R3,000 to R15,000 depending on model and port count. Installation and configuration typically add R2,500–R5,000. We include three years of parts and labour warranty. Many clients find this compares well to the cost of network downtime or security problems.
Q: Will a UniFi switch solve my WiFi problems?
Not directly—the switch manages wired network traffic. However, most WiFi problems trace back to poor wired infrastructure or configuration. Once we've installed a proper switch, we can add UniFi access points, which integrate seamlessly and give you unified management. We often recommend this combination.
Q: What happens if my switch fails during load shedding?
With proper UPS backup (which we configure), your switch stays active for thirty minutes to two hours depending on UPS size. This keeps your most critical systems running and lets devices maintain connections gracefully. We discuss load shedding-specific planning during your assessment.
