Bitwise AND operation
result
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.

Ensure that the UPS IP address is unique on the network segment. Otherwise, the WebUI

IP address allocation
− 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 an LAN switch or router with the
DHCP function, the IP address can be allocated manually or automatically.
 Manual: 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.
IP address
Set an Ethernet IP address that ranges from 0.0.0.0 to 223.255.255.255. The default value
is 192.168.0.10.
Subnet mask
Set an Ethernet subnet mask that ranges from 0.0.0.0 to 255.255.255.255. The default
value is 255.255.255.0.
