5.7 System Notification
5.7.1 SNMP Access
The SNMP-NV6 card supports the SNMP protocol. You can use an NMS to manage a UPS
through a network. You must enter the IP address of the workstation in the SNMP Access
Table to prevent any unauthorized users from configuring the SNMP-NV6 card via SNMP
protocol. The maximum number of IPs is 256.
If you use a workstation with SNMP Manager installed, or if you set more restrictive SNMP
access, you can use the SNMP Access to add the IP address of the PC, which you use to
modify the access permission. If the IP address is set as 0.0.0.0, it means the IP address will
be ignored. The SNMP-NV6 card will check the community string first to identify whether the
incoming packet is Read Only or not.
5.7.2 SNMPv3 USM (User Based Management)
SNMPv3 is an encryption version of SNMP protocol. Before you can access the SNMP OID
from the SNMP-NV6 card using SNMPv3 protocol you have to configure the SNMPv3 USM
table.
