IP address allocation
●

Issue 02 (2022-12-30)
If the MDU is connected to a computer over a network cable, the IP address
can only be allocated manually. The IP addresses of the MDU and computer
must be on the same network segment, and must be different.
If the MDU is connected to a computer over a LAN switch or router with the
DHCP function, the IP address can be allocated manually or automatically. IP
address allocation is set to Manual by default.
– 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.
