Cascade Function

Allows additional units to be staged on/off based on the temperature or humidity
requirement.

iCOM Network Setup Process

To setup a system network with the iCOM control requires a complete
understanding of the control processes and parameter programming to insure the
proper functional operation without incident. To insure the setup is correct and
that the operation will function as selected you need to map both the room layout
and the unit setup. First, read and record all programmed settings in all of the
single units. Second, document the network parameter settings that are needed
and identify the numerical order of the units to be networked. The order of the
setup process is very important.

Basics for Cooling Unit Placement

Installation instructions are found in the product manuals for the Cooling units.
Networking setup should include these additional factors for planning.
• Locations of heat loads in conditioned space.
• Air distribution for cooling.
• Number of operating units versus standby.
Multi-unit networking hardware
Minimum Network Switch Requirements:
•
IEEE 802.3, IEEE 802.3u
•
10/100 Mbps speed
•
Multiple RJ-45 ports – one shared RJ45 uplink
•
CAT 5 or greater patch cables (straight through) in the proper lengths
not to exceed 150 ft. maximum length each. One for each board and large
display added into the iCOM network. Cable management will apply.

Basics for Programming

An IP address number will be used to identify each receiver/ sender of information.
(See Computer and Network Terms in Training and Service Manual)
The iCOM Network is a Class C Private Network and will use the
192.168.254.xxx series of static IP address. This has nothing to do with the local
building or owner network. The iCOM Network may only be connected to these
networks through a Liebert WEB Card or 485 Card using the Liebert Intellislot.
A series of basic rules must be followed to connect and program the units for this
private iCOM Network. See the following rules.
