This systematic approach helps us identify if the issue is a simple physical connection or a deeper network requirement.   #### Phase 1: Observation & Documentation Before resetting any equipment, please capture the current state of the system. This data is vital for our technical team. 1. **Check the Touch Panel:** If the screen is active, does it show a specific error message (e.g., *"Comms Error"* or *"Missing - Redundancy Not Ready"*)? Please take a photo of the screen. 2. **Inspect the "Core" (Main Processor):** Locate the Q-SYS Core in the equipment rack. - Is the front light **Solid Blue**, **Blinking Red**, or **Amber**? - Is there any text on the front LCD screen? 3. **Note the Timing:** Does the disconnect happen at a specific time of day, or when a specific light/device in the room is turned on? --- #### Phase 2: Physical Connection Audit Often, "ghost" disconnects are caused by a cable that has vibrated loose or a failing patch cord. 1. **The "Click" Test:** Go to the back of the device that is dropping offline. Unplug the network cable (the one resembling a thick phone cord) and plug it back in. Ensure you hear and feel a physical **"click."** 2. **Link Lights:** Look at the small green and amber lights where the cable enters the device. - **Solid Green/Blinking Amber:** Normal. - **No Lights:** The cable is not receiving power or data from the switch. 3. **Cable Path:** Ensure the network cable is not pinched by rack doors or coiled tightly around power bricks, as electromagnetic interference can cause micro-disconnects. --- #### Phase 3: Controlled System Restart If the physical connections are secure, a synchronized restart can often clear "stuck" network addresses. **Please perform these steps in this exact order:** 1. **Power Down:** Turn off the Q-SYS Core and any connected amplifiers. 2. **Refresh the Network:** If you have access to the dedicated AV network switch, unplug its power for **30 seconds**, then plug it back in. Wait 3 minutes for the switch to fully "boot up." 3. **Power Up:** Turn the Q-SYS Core back on. Wait for the front light to turn **Solid Blue**. 4. **Final Check:** Turn on the amplifiers and check the touch panels. --- #### When to Contact Support If the steps above do not resolve the disconnects, the issue likely involves **Network Clocking (PTP)** or **Bandwidth Congestion**, which requires software-level tools to fix. **Please provide us with the following when you call:** - Photos of any error messages. - A list of which specific devices (mics, speakers, or screens) stayed on vs. which ones dropped. - Confirmation that "Step 2: The Click Test" was completed.
