10 Communication
The UPS supports SNMP communication, Modbus protocol communication, dry contact communication and Velocity
protocol communication. This chapter provides information relevant to these types of communication.
Selecting 'Velocity' means the system supports the Velocity protocol communication.
10.1 SNMP Protocol Communication
If you need to monitor the UPS through network, you may select the UNITY card or SIC card provided by Vertiv. These two
cards support SNMP protocol. Both the UNITY card and SIC card are network management cards which make the UPS an
IOT device. 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 sending a mail.
The UNITY card and SIC card provide three approaches for you to monitor your intelligent equipment and equipment room
environment:
• Web browser: You can use Web browser to monitor your intelligent equipment and equipment room
environment through the Web server function provided by the UNITY card or SIC card.
• Network management system (NMS): You can use NMS to monitor your intelligent equipment and equipment
room environment through the SNMP function provided by the UNITY card or SIC card.
• RDU-A: The network management software for equipment room power and environment. You can use RDU-A to
monitor your intelligent equipment and equipment room environment through the TCP/IP interface provided
by the SIC card.
The SIC card can also work with the Network Shutdown software developed by Vertiv to provide automatic safe shutdown
function for your computer installed with Network Shutdown, so as to avoid data loss.
The communication card should be installed in the Intellislot port (see Figure 4.4 on page 42) in the UPS.
