Manual
: Check that the IP addresses of the MDU and computer are on the same
network segment, and are different. Set the UPS IP address to be in the same subnet
as the computer IP address. Perform the bitwise AND operation for the UPS IP
address and the computer IP address with the subnet mask respectively. If the
operation results are the same, the two IP addresses are in the same subnet.
AND operation rule: 1 AND 1 = 1, 1 AND 0 = 0, 0 AND 1 = 0, 0 AND 0 = 0. That
is, when the corresponding bits are both 1, the result is 1. In other cases, the result is
0.

Automatic
: The MDU automatically searches for available IP addresses in the
connected network. Ensure that the MDU and computer IP addresses are on the
same network segment.
After you restart the device,
