− If the MDU is directly 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 in the same network segment, and must be different.
− If the MDU is connected to a computer through a LAN switch or router with the
DHCP function, the IP address can be allocated manually or automatically.
 Manual: Check that their IP addresses are two different values on the same
network segment. Set the UPS IP address to be in the same subnet as the PC IP
address. Perform the bitwise AND operation for the UPS IP address and the
PC 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 PC are on the same network
segment.
You can set IP address allocation to Manual or Automatic. After you restart the device, IP address
allocation changes back to Manual. IP address is the IP address that you have previously set.
