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.
After you restart the device,

. The IP address is set to the
IP address set previously.
