Emerson Liebert PSA Line-Interactive UPS 500-1500VA User Manual

Sending test messages can help determine whether targeted clients are properly set up to receive 

notifications of UPS-related events. To do so:

• Click  on  the  Overview tab, right-click on the UPS device name, click on Properties, then on the 

Clients tab.

• Select one or more clients from the MultiLink Network Shutdown Clients list and click on the 

Test button. This causes Liebert MultiLink to send a test message to each targeted client 

computer selected.

• To verify that test messages were sent and received, check both the host computer and client 

computers as follows:
a. The host computer will display one of the two messages shown below. If any test messages are 

sent, a verification similar to the one at left below appears on the computer running Liebert 

MultiLink, showing the total number of test messages that were sent. This is not an 

indication that the clients received the messages.

If any messages are not sent, an error message will appear on the host computer. The error 

message, above right, indicates that the entry in Client Hostname or IP Address is an 

invalid IP address or is a hostname that cannot be resolved. The selected computer probably 

is not configured in the Domain Name Service. If it is configured with its associated reverse 

lookup entry, there might be a problem accessing the name service. Try to ping the name 

server and correct any problems there. If no problems are found at the server, check the 

configuration at the client end.

b. Check all targeted client computers to verify that each received a test message similar to the 

one shown below.

This message should appear within five seconds of being sent. If it does not, compare the time 

it is displayed with the time on the message. If the lapse is more than 10 seconds, there is a 

local name service problem. If the message is received within five seconds, the local name 

service configuration is correct.
If test messages are received in a timely fashion and the entry was a hostname, DNS or other 

name services are correctly configured.
