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

The Clients tab allows you to designate computers that will receive notification of UPS-related 

events, such as Low Battery. Before doing so, you must first obtain a MultiLink Network Shutdown 

License for the appropriate number of clients and install the license on the host computer (see 8.4.15 - 

Configure Menu - Upgrade License).
Each targeted client must be running Liebert MultiLink 4.x, 3.x or 1.x. For 4.x and 3.x clients, choose 

the connection type MultiLink Basic Notification Source during setup (see 3.1.1 - MultiLink 

Basic Notification Source for an overview, 5.2.5 - Define Network Connection for installation 

instructions and 8.3.3 - Properties - Setup Tab for configuration).

• Click on the Overview tab.
• Right-click on the UPS device name to open a pop-up menu, then click on Properties.
• In the Properties window, click on the Clients tab.

The values in the MultiLink Request Status Port box relate to communications between the host 

computer and targeted client computers.

• The default port, 3027, is correct for most applications. Contact Emerson Network Power 

Technical Support for assistance.
Ensure that all MultiLink Network Shutdown Clients are configured to request status from 

the host computer on the port specified in the MultiLink Request Status Port box. The host 

computer must be running Liebert MultiLink 4.x or 3.x, and all clients must be running Liebert 

MultiLink 4.x, 3.x or 1.x.

• Check to make sure the entry in the SNMP Community String box matches that in your other 

systems. The default is LiebertEM (case-sensitive).
