Chapter 9
Communication
The UPS supports SNMP communication, Modbus protocol, dry contact and Velocity protocol communication. This
chapter provides information about these communication systems.
Refer to the corresponding settings in Table 4-7 for communication protocol transfer. Selecting 'Velocity' means the
system supports the Velocity protocol communication.
9.1
SNMP Protocol Communication
If you need to monitor the UPS via a network, you may select the IS-WEBL card supplied by Vertiv.
The IS-WEBL card is a network management card that supports the SNMP protocol and can be used to convert the
UPS into a fully compatible network device. It can also be connected to the IRM series sensor to provide
environmental monitoring functions. When the intelligent equipment generates an alarm, the IS-WEBL card can
notify the user by logging the event, sending any information that may be captured, and sending a mail.
The IS-WEBL card provides three approaches for you to monitor your intelligent equipment and equipment room
environment:
Web browser. You can use a Web browser to monitor your intelligent equipment and equipment room
environment using the IS-WEBL card Web server function.
Network management system (NMS). You can use NMS to monitor your intelligent equipment and
equipment room environment via the IS-WEBL card SNMP function.
The IS-WEBL card should be installed in the UPS Intellislot port (see Table 3-7).
For information about installing and setting up the IS-WEBL card, refer to the
Liebert IntelliSlot Web Card Quick
Start Guide
.
9.2
Modbus Protocol Communication
The UPS can achieve Modbus communication through the optional IS-485L card. For information about installing
and using the IS-485L card, refer to the
Liebert IntelliSlot Modbus 485, Modbus IP And BACnet IP Reference Guide
.
9.3
Dry Contact Communication
The UPS provides the following two dry contact communication methods:
IS-Relay card (option)
Dry contact port
9.3.1
Communication via IS-Relay Card
The UPS may be supplied with an optional IS-Relay card that can be used to manage UPS monitoring dry contact
signals. The IS-Relay card should be installed in an Intellislot port (see Figure 3-7) on the communication box in the
cabinet. For information about installing and using the IS-Relay card, refer to the
Liebert IntelliSlot Relay Card User
Manual
.
9.3.2
Communication via Dry Contact Port
For specific, on-site needs, the UPS may require auxiliary connections for functions such as acquiring external
equipment status information, providing alarm signals to external devices, and remote EPO. These functions may be
realized using the following interfaces on the external interface board (EIB):
Input dry contact port
Output dry contact port
EPO input port
For detailed information about these ports and the associated functions, refer to 3.2
