Replacing a Display Module

Procedure

1. (Optional) Back up data. If the WebUI or ECC is not configured, skip this step.
   1. Insert the USB flash drive into the main control board (or main control module). Go to Maint > USB Operations > Export as an admin user to back up data to the USB flash drive.
   2. Log in to the WebUI of the smart cooling product as an admin user. Choose Maintenance > Configuration File. (Optional) After entering Configuration File Encryption Password, tap Back Up Current Settings to back up data to the computer.
   3. Log in to the WebUI of the ECC as an admin user. Choose Query > Export Data and set Data Type to the smart cooling product. Tap Export Local Data of Southbound Devices to back up data to the computer.
2. Replace the display module.
   • Do not frequently or quickly disconnect and connect the DP cable of the display module. Do not forcibly pull the DP cable.
   • You are advised to power off the main control board (or main control module) before replacing the display module.
   • If the main control board is not powered off, you are advised to back up the configuration file of the product by referring to a or b.
   1. Open the front door and do not damage the cables connected to the display module.
   2. Remove the cables from the display module.
   3. Use a Phillips screwdriver to remove the four screws and gaskets that secure the display module, and pull out the display module.
      • When pushing the display module leftwards or rightwards, pay attention to the buckles on the panel to prevent damage to the display module.
      • The gasket is used to adjust the distance between the display module and the door panel.
      • The gasket dimensions are 25 mm (L) x 12 mm (W) x 2 mm (H) and the center aperture is 6 mm.

   4. Install the new display module in the original position on the front door by performing the preceding steps in reverse order.
   5. Connect the control signal cables to the display module. Close and lock the front door.
   • If the main control board is not powered off, the main control board detects and initializes the display module after the DP cable is connected to the display module. This process takes 10s to 30s. Wait for 5s to 10s. The indicator on the panel turns on, but the screen does not turn on. Wait for another 5s to 20s until the screen is restored to the state before the replacement.
   • If the main control board is powered off, power on the main control board after the DP cable is connected to the display module. After the main control board is powered on, the startup logo and self-check progress bar are displayed on the display module. Then, the main screen is displayed. The whole restoration takes about 60s to 90s.

3. (Optional) Import the configuration. If the WebUI or ECC is not configured, skip this step.
   1. Insert the USB flash drive into the main control board (or main control module). Go to Maint > USB Operations > Import Config as an admin user to import the backup data in the USB flash drive.
   2. Log in to the WebUI of the smart cooling product as an admin user. Choose Maintenance > Configuration File, and choose the backup data. (Optional) After entering Configuration File Encryption Password, tap Upload to import the data to the WebUI.
