After you restart the device, IP address allocation changes back to Manual. The IP address is set to the
IP address that is set previously.
Issue 02 (2020-01-10)
If the MDU is directly connected to a computer, the IP address can only be allocated
manually. The IP addresses of the MDU and network management system 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 allocation is
used by default.
− Manual: The IP addresses of the MDU and computer must be in the same network
segment, and must be different. 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
means when the corresponding bits are both 1, the result is 1. In other cases, the
result is 0.
− Automatic: The MDU automatically queries available IP addresses in the connected
network. Ensure that the MDU and PC are on the same network segment.
