Emerson GXT2-PP20KRT208 用户手册

The parallel POD supports the orderly shutdown of computer operating system through its compati-

bility with Liebert MultiLink 1.5 software. When properly configured to operate with Liebert Mul-

tiLink 1.5, the parallel POD will operate as a complete system; On Battery and Low Battery events 

will not be sent from the UPS when it is operating in redundant mode and the remaining UPS is able 

to support the total load.
For the paralleling system to work properly with Liebert MultiLink 1.5, each connected 10kVA UPS 

must have an SNMP card properly installed and configured in the Liebert IntelliSlot

®

 bay. Liebert 

MultiLink 1.5 will not work properly with the parallel system through the serial port connection.

The SNMP card must be properly configured with an IP ADDRESS, NETMASK and GATEWAY. 

Refer to the SNMP card user manual for detailed instructions. The SNMP card must also be config-

ured with a community string to be monitored by Liebert MultiLink. For details, refer to the Liebert 

MultiLink 1.5 user manual, SL-53620, available at the Liebert Web site, 

Liebert MultiLink 1.5 also must be properly configured for the software shutdown to work properly 

with the parallel system. Refer to the Liebert MultiLink 1.5 user manual for detailed configuration 

instructions. Two important settings required for Liebert MultiLink shutdown to work properly are:

• The connection option “Liebert UPS (using SNMP port 162)” must be selected, either during 

installation or later (see Figure 3; refer to the MultiLink 1.5 user manual, SL-53620, for details).

• The options “Enable shutdown after an on-battery event” and “Enable shutdown after a low-bat-

tery event” must be selected for Liebert MultiLink to initiate shutdown when either of these 

events occur (see Figure 3; refer to the MultiLink 1.5 user manual, SL-53620, for details).
