Examples using "5NN00" ports:
• •
To access the primary device via HTTPS, the IP address is:
https://192.168.84.77:50000/
• •
To access the primary device via HTTP, the IP address is:
http://192.168.84.77:50100/
• •
To access the primary device via SSH, the command is:
ssh -p 50200 192.168.84.77
Examples using standard TCP/UDP ports:
• •
To access the primary device via HTTPS, the IP address is:
https://192.168.84.77:443/
• •
To access the primary device via HTTP, the IP address is:
http://192.168.84.77:80/
