SNMP Connection
Figure 3 shows examples of two Liebert MultiLink configuration options for a UPS with an SNMP 
connection. 
The SNMP card installed in the UPS can be monitored by up to 20 MultiLink Agent computers, or it 
can notify up to 20 MultiLink Client computers for automated shutdown. (These computers must be 
running Liebert MultiLink.) With the proper Liebert MultiLink Network Shutdown License installed, 
MultiLink Agent computers can forward On Battery and Low Battery traps received from the SNMP 
card to MultiLink Clients being powered by the UPS.
