IP address allocation
●
●
Issue 12 (2023-05-26)
If the MDU is directly connected to a computer, 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 allocation is used by default.
– 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.
NO TE
After you restart the device, IP address allocation changes back to Manual. The IP address
is set to the IP address set previously.
