Hello, friend!
Because I'm not sure what you mean by the default IP.
The default IP address of the ETH port on the MA5620 is 10.11.104.2.
If you want to log in to the MA5620/MA5626 through the out-of-band management port of the MA5620/MA5626 through Telnet or Secure Shell (SSH) to perform maintenance and management, you need to plan the IP addresses of the maintenance network adapter and operation control network port.
For more information, click: Configuring Outband Management
Thanks!
