Issue when connecting locally to the NETA-21 web UI
CAUSE: 
The DHCP server is not activated or the PC not requesting an IP address.
SOLUTION: 
• Disconnect and reconnect the Ethernet cable at the PC.
• Push the SD/RJ45 button for 5 seconds again and verify that the triangle shaped LED 
near PC / ETH1 text blinks green. The LED shows a static green when the PC has 
successfully requested an IP address.
• Verify your PC settings. If it is necessary, disable the WLAN and set the PC to obtain 
the IP address automatically.
