What is Uninterruptible Power Supply (UPS)?

You can expect up to four hours back-up time under ideal conditions. To get the longest back-up time, we recommend you turn off the Wi-Fi on your Telstra Smart Modem when using the UPS.

The UPS charges while plugged in to an AC mains power socket and supplies power directly to the modem if the mains electricity switches off for any reason.

No, the UPS for Telstra Smart Modem is only compatible with the Telstra Smart Modem Gen 3, Gen 2 and Gen 1.

If your handset is connected to mains power, switch off the power point and try to make a call. If your device doesn’t require mains power to function, the handset will continue to make and receive calls. If not, you’ll be unable to make any outgoing calls.

AC mains power is how electricity is supplied through power points in your home. Any item requiring connection to a power point to work will not work in a power outage or when the power point is switched off. 

On your Telstra Smart Modem Gen 1, Gen 2 and Gen 3, press the Wi-Fi button (located at the back of the modem) to turn your Wi-Fi off and on. We don’t recommend turning it off if you’re using the modem to connect to the internet using Wi-Fi.

The UPS for Telstra Smart Modem should always be on and it has an Auto Switch-Over feature. This means if the mains electricity fails, the UPS for Telstra Smart Modem will automatically kick in.

The UPS for Telstra Smart Modem should be replaced after 2 years. 

The UPS for Telstra Smart Modem replaces the existing power adapter (cord) on your Telstra Smart Modem. 

1. Unplug the power adapter cord from the power point on the wall 
2. Unplug the power adapter cord from the back of the modem and store it in a convenient place
3. Replace the power adapter cord with the UPS to the back of the modem
4. Plug the UPS in to the power point on the wall and switch it on.

Once the UPS is connected between the Telstra Smart Modem and mains power, allow at least three hours for it to charge and then switch off the power at the power point. The UPS for Telstra Smart Modem should start supplying power to the Telstra Smart Modem.

The ON/OFF button should only be used to conserve back-up power during a power outage, or if the UPS is disconnected from AC mains power. When using the button, your Telstra Smart Modem will require adequate time to boot up so we recommend only using this feature where the power outage is expected to be longer than four hours.

To turn off the UPS press the ON/OFF button twice. To turn it back on press the ON/OFF button once. These instructions can also be found on the device.
