Hello All, I’m currently in the process of configuring an A10 Thunder 1060 appliance, and I’ve run into a bit of a challenge I’m hoping someone in the community can assist with. Due to a limited number of available power receptacles in the staging area, I’m operating the appliance outside of its ideal setup. As expected, the device’s **audible alarm is sounding** , likely because it’s detecting that redundant components (like a second PSU or fan module) are not connected or active. My goal is to temporarily disable or mute the audible alarm while I complete the configuration process. Once the appliance is fully staged and moved into production, it will be installed in a proper environment with all components connected. Has anyone dealt with this before? 1. Is there a CLI command or a hardware-level option to suppress the alarm temporarily? 2. Will disabling it affect the configuration or logging behavior in any way? 3. Are there any best practices or precautions I should be aware of when doing this? Any guidance would be greatly appreciated. Thanks in advance! ---

Hello pagan3940, As you mentioned, the beep is expected behavior when running with single PSU. As far as I know there is no CLI command to stop the beep (even temporarily) unfortunately. Thanks. ---

There is a small button on the back of the A10 to mute the alarm. The button is just to the left of the PSU cage. ![psu](https://us1.discourse-cdn.com/flex002/uploads/a10_community/original/1X/5ebea438c4a7b2e8a2cae3284f7b28aed36e53d7.jpeg)
