What does it mean if the Bridge's Power LED is orange?
This means the Bridge is checking the remote upgrade channel. This action does not disrupt the performance of the Bridge nor its connectivity to the platform. A solid orange or solid green power LED is an operational state for the Bridge and is not a cause for concern.
To remove the orange LED, navigate to the Connection Setup in the Configuration Tool for the Bridge and disable the "Enable remote firmware update" box and Save and Reboot the settings.

Read the attached quick guide below for steps on how to access the Bridge's Configuration Tool settings.
