How a UPS works

Loadshedding has affected almost every part of our lives – including access to the internet. But with fibre and a UPS device, that doesn’t have to be the case.

We rely on the internet for so many things, from booking a holiday to watching movies on Netflix and googling plotlines. So when there’s loadshedding and not only are we left in the dark, but we’re also without our main source of entertainment, making those 2–4 hours seem even longer. Luckily, if you plan ahead, there is a way to avoid interruptions with Vodacom Fibre’s UPS.

What does UPS stand for?

UPS is the acronym for Uninterruptible Power Supply or Uninterrupted Power Supply. Basically, it is a battery backup device.

What does a UPS device do?

When your regular power source stops working (when there’s an electricity cut, for example), a UPS device supplies energy in the interim so you can stay connected to wifi. Vodacom Fibre’s UPS device can provide power for up to four hours, depending on how many devices are plugged in.

When and how should I connect my UPS?

Your UPS should always be plugged into an electric socket and your devices should be plugged onto the UPS when you are using them. Your UPS should always be plugged into an electric socket and your devices should be plugged into the UPS when you’re using them.
To connect the UPS, please refer to the user manual provided in the UPS box. 

How do I turn the UPS on?

There is a button at the front of the UPS, press it and the device will turn on. There is no need for anything further to be done. A green light will illuminate on the front of the UPS to indicate it is operational and charging correctly.
If there is no power, the yellow/orange light will be on and the device will beep. This means that there is no mains power but the devices connected to the UPS is powered via the UPS battery.
Should there be no lights at all, check if the device is plugged in and the wall socket is switched on and charged fully. It takes 4-6 hours to fully charge.

What does the lights and sounds mean?

AC Mode - Green LED on
Battery Mode - Flashes yellow
Low Battery - red LED on, sound every second
Fault - red LED on, sound every 10 seconds

How long can it provide power for?

The Vodacom supplied UPS (PSS AP1000VA UPS) has 1000VA of power and can support Vodacom Fibre related equipment (fibre terminating unit, router, phone LTE dongle, and a laptop) for approximately 4 hours.
