10 Communication

This chapter provides information about the compatible communication protocols.

Vertiv™ Liebert® APM2 Supports:

• SNMP Protocol communication

• Modbus protocol communication

• Dry contact communication

• Velocity protocol communication

10.1 SNMP Protocol Communication

Vertiv's UNITY or SIC network management cards make the UPS an IOT device. These cards support SNMP protocol that

helps to monitor the UPS through network.

IRM series sensor can also be connected to these cards to provide environmental monitoring function. When the intelligent

equipment generates an alarm, the UNITY card and SIC card can notify the user by recording the log, sending trap

information, and trigger e-mails.

The UNITY card and SIC card provide three approaches for you to monitor your intelligent equipment and equipment room

environment:

• Using web browser. Through the Web server function provided by the SIC card or UNITY card.

• Using Network Management System (NMS) through the SNMP function provided by the SIC card or UNITY card.

• Using SiteMonitor, network management software for equipment room power and environment through the

TCP/IP interface provided by the SIC card.

The SIC card can also work with the Network Shutdown computer safe shutdown program developed by Vertiv to provide

automatic safe shutdown function for your computer installed with Network Shutdown, so as to prevent data loss.

The communication card must be installed at the Intellislot port. See Figure 4.5 on page42.

For the installation and setting information of the SIC card, refer to the Site Interface Web/SNMP Agent Card User Manual in

accessory.

• IS-Relay card (Optional)
