TLDR

On your BAKERLUX SHOP.Pro unit, error E04 "IP Address Missing" indicates that the oven's network configuration is incomplete, specifically when DHCP mode is set to OFF and manual network parameters have not been correctly entered. This prevents the oven from connecting to your local network or the internet. To resolve, access the network settings and accurately input the required static IP address, subnet mask, gateway, and DNS server details.

Technical Details

Repair Steps:

  1. Verify Network Settings Access: On your UNOX BAKERLUX SHOP.Pro control panel, navigate to the network settings menu. This is typically found under “Menu” > “Settings” > “Network” or “Connectivity”.
  2. Check DHCP Mode: In the network settings, confirm whether DHCP (Dynamic Host Configuration Protocol) mode is enabled or disabled. The E04 error specifically states “Only if DHCP mode is set to OFF”, indicating a manual configuration issue if it’s disabled.
  3. If DHCP is OFF, Manually Configure IP Address: If DHCP is intentionally disabled, you must manually input the static IP address, subnet mask, default gateway, and DNS server addresses. Ensure these parameters are correct for your local network, consulting your IT administrator if necessary. Double-check for typos.
  4. If DHCP is ON, Troubleshoot DHCP Server: If DHCP is set to ON but the oven still reports E04, this suggests the oven isn’t receiving an IP address from your network’s DHCP server. Verify the network cable connection to the oven and check the network switch/router for proper operation. You might need to reboot your network equipment.
  5. Inspect Network Cable and Connection: Ensure the Ethernet cable connecting the oven to the network is securely plugged in at both ends and is not damaged. Try swapping the cable with a known good one. A loose or faulty cable is a common cause.
  6. Test Network Connectivity: Some UNOX models offer a network test function within the settings menu. Utilize this to diagnose connectivity issues. Even a simple ping test from another device on the network to the oven’s assigned IP (if static) can help confirm basic network communication.
  7. Reboot Oven and Network Equipment: Power cycle the UNOX BAKERLUX SHOP.Pro unit by turning it off and then back on. Additionally, consider rebooting your network switch or router to clear any temporary network glitches.
  8. Consult Network Administrator or UNOX Support: If the issue persists after these steps, the problem may lie with your network infrastructure, firewall settings, or require deeper diagnostic tools. Contact your IT administrator or an authorized UNOX technical service provider for further assistance.
