1 GETTING STARTED WITH ICOM CMS

The web-based user interface for iCOMCMS offers the highest capability for unit control, communication,
and monitoring of Liebert® Thermal Management units. It is available factory-installed on new units and
assemblies or may be retrofitted in existing units. For details on first-time set-up and retro-fit installation,
see Installing and Connecting iCOMCMS on page 35.

1.1 Liebert iCOM CMS has 3 Main Features

• A web-based user interface providing remote connectivity to a unit-level display with full
read/write capabilities.

• BMS connectivity via Modbus RTU, Modbus TCP/IP and SNMP.

• Mobile cloud/Mobile app access to view status and notification information on a mobile device.

NOTE: You can control the unit using the web-based UI, including unit on/off, setpoints, and alarm set­up. The mobile app, however, does not allow unit control. It is a read-only interface for notifications.

1.2 What Features Would You Like to Use?

You can use one or all of these features, and the following sections provide an outline of the steps to set­up and get started using each one.

1.2.1 Access the web-based user interface

Place iCOMCMS on your corporate network by configuring the network settings using the Connection
Settings menu. See Connection Settings on page 25.

Once set-up, everyone using a computer with corporate-network access and provided with the assigned
IP address can open the web UI in a web browser.

1.2.2 Access the BMS protocols

To configure communication with your building-management system, use the BMS Setup menu. See

External Monitoring and Building-management systems on page 22.

1.2.3 Access the mobile cloud/mobile app

Place iCOMCMS on your corporate network by configuring the network settings using the
ConnectionSettings menu. See Connection Settings on page 25.

Then, register the iCOMCMS cooling unit using the Cloud Setup menu. See Registering with the

Administration Portal toAllowMobile-appUsers Access on page 41.

• Once the unit is registered, the e-mail address you used to register the device will receive a
password-change e-mail with the credentials to log-in to the iCOMCMS Administration Portal
(www.icomcms.com) and the mobile app.

1 Getting Startedwith iCOM CMS

5

• Visit the Administration Portal at icomcms.com, and log-in to manage the registered devices
and mobile-app users as follows:

• Create a division.

• Create a building and assign the building to a division.

• Assign the registered iCOMCMS unit to a building.

• Create users, define the user’s role (Administrator, Mobile-app only), set-up e-mail or
SMS-text notifications, and assign buildings to the user, which determines what units
they can view in the mobile app.

• The mobile-app users will get an e-mail with log-in credentials, and can download the
iCOMCMS mobile application and log in to receive notifications.

1.3 iCOM CMS web-based user interface

The web-based user interface speeds set up and installation and simplifies control of Liebert® cooling
units.

• User, service and advanced menus are password-protected to prevent unauthorized changes
to cooling-unit operation. See Logging-on to iCOMCMS and Unlocking controls on page 9.

• iCOMCMS ships with default settings for efficient and effective operation of most cooling-units
and is easily configured to meet any need.

• iCOMCMS requires a Google Chrome web browser version 50.0.xx or higher.

Figure 1.1 on the facing page, shows the controls and options available on the main display.
