This article explains how to properly upgrade an APC device’s firmware.

Follow these steps to upgrade your device:

It is highly recommended to use firmware images of the same version to guarantee successful link performance between APC units.

Step 1. Launch the device’s GUI and navigate to System > Firmware upgrade:

Apc-fw-update1

Step 2. Press Upload firmware and select the firmware file from your computer:

Apc-fw-update2

Step 3. Once the firmware is successfully uploaded on to the APC device, click Upgrade:

Apc-fw-update3

Do not switch off and do not disconnect the device from the power supply during the firmware upgrade process because the device may become damaged.
