7.7 (Optional) iCooling Function

Working Principles
The iCooling function includes L1/L2 linkage and linkage between smart cooling product
indoor and outdoor units. Currently, only L1/L2 linkage is supported. The smart cooling
products that support this function are Netcol5000-A025 and Netcol5000-A042.The function
of L1/L2 linkage is to enable smart cooling products to quickly respond to load changes and
implement on-demand cooling. The smart cooling products can be regulated to achieve
optimal energy efficiency.

Prerequisites
Before setting the iCooling function, the following requirements must be met:


receiving place on the infrared remote control module, and press the power button once.
If the green indicator blinks, it indicates learning success of the first key code.
The device will quit learning operating mode automatically once finish learning.
After the smart cooling product is shut down, direct the infrared remote control module
to the smart cooling product and press the SW button once.
Check whether the smart cooling product starts. If it starts, the control function works; if
it cannot start, rectify the fault and perform the preceding steps again.
L1/L2 disabled
− For the cold aisle containment in the smart module, all IT cabinets use the cooling
capacity in the cold aisle and the temperatures inside the cold aisle are unevenly
distributed due to the uneven air flow.
− The cooling requirements of the IT cabinets can be met and partial hot spots can be
avoided only if the cooling capacity provided by the smart cooling product matches
the heat load of the corresponding IT cabinets.
L1/L2 enabled
− The cold aisle is divided into multiple areas according to the smart cooling product
positions. The cooling capacity from any smart cooling product in the areas can
meet the temperature requirements of the IT cabinets because the temperature
unevenness is relatively low.
− The smart cooling products in each area quickly respond to load changes in the
areas and are regulated to achieve optimal energy efficiency.
The scenario is dual-row cold aisle containment and the following conditions are met:
− smart cooling product should be placed face to face.
− An integrated UPS, integrated PDC, or precision PDC is deployed inside the smart
module. The ECC800 can collect statistics on IT branch power information for each
IT cabinet and network cabinet.
− Rack environment units and cabinet-level temperature sensors are installed for IT
cabinets or network cabinets. The ECC800 can monitor the temperature of each
cabinet.
