SNMP Interface sending messages to UPS log– But Why

1.      The 10.0.0.1 belongs to a server which is configured to send SNMP messages to this UPS. And sends well over 50 messages a night  
        Which get recorded in the ups log.  Server is Windows 2012 R2
                                                              Why is the UPS sending these messages. ?
Note: There is no unauthorized user or any user attempting to access the ups from 10.0.0.1.     I have also cleared the web browser on this server.   Then why is the ups sending messages.

The message is: Informational - System: Detected an unauthorized user attempting to access the SNMP interface from “example -10.0.0.1 “.   I have an Smart-UPS 2200 RM XL APC UPS with an ip on its network interface and its configure to receive SMMP messages.
