3.3.2 Configuring Quick Start
In the event of a power interruption to the Vertiv™ Liebert® iCOM™ controller, the unit components and controls shut down.
Normally, after power is restored, the Liebert® iCOM™ controller must fully boot, and no cooling or air flow occurs until the
controls have fully booted. Quick Start lets you determine the fan and cooling output that the unit will provide before the
controller fully boots. When configured, the unit can provide airflow and cooling within 10seconds after power is restored to
the controller. Quick Start can be applied to fan, chilled-water, DX, and PRE-pump functions. Quick Start operates only during
Liebert® iCOM™ application boot, then normal controller operation resumes.
To Configure Quick Start

2. Refer to Quick Start Options below , and select the configuration options for your system.
NOTE: Depending on the type of thermal management unit, included components, and control settings of your system,
all of the options listed may not be available on your Liebert® iCOM™ display.
