functions. The SNMP card allows users to remotely manage the UPS by using a
network management system (NMS), NetEco, or a web browser on a computer
network. A maximum of 16 SNMPv3 users and 1 SNMPv1&SNMPv2c user can
manage the UPS. The web user interface (WebUI) supports a maximum of two
concurrent online users.
The SNMP card has an exquisite, advanced, and unique design, and features high
performance and reliability. It has the following functions and features:
● Supports UPS2000-G series and implements parallel system management
using only one SNMP card.
● Adapts to the 10 Mbit/s, 100 Mbit/s fast Ethernet (FE) by using an IP address
that is
congurable on the LCD.

● Supports SNMP agent v1, v2c, and v3. The UPS MIB library can be
downloaded from its own web page, instead of any CD-ROM.
