6.4 Additional Settings for 20-kW, 3- to 6-rack Systems—N+1 cooling Only
(2 PDX/PCWs - one cooling unit on, one in standby)
These settings apply to a SmartRow DCR that has two Liebert PDX/PCWs, one operating and one in
standby mode.
Before making these changes, complete the adjustments in Liebert iCOM Setup for all SmartRow DCR
Types on page 55.
These settings allow the cooling units to share the remote 2T temperature sensor data when the cooling
units are operating or on standby. This ensures that the temperature readings from all racks are factored
into the cooling capacity calculation (CFC: Call for Cooling). Additionally, if the heat load temporarily
exceeds the capacity of the SmartRow DCR’s operating cooling unit, the standby unit will be
automatically started to assist. When one cooling unit can again maintain the load the second unit will
return to standby mode (cooling and fans Off).
1. Make these settings in the iCOM Service Menu > System / Network Setup:

for all SmartRow DCR Types on page 55) before setting the Teamwork Mode, followed by setting
Standby and Cascade modes.
