Overview
Product overview
The HPE Adaptive Rack Cooling System is a supplemental cooling system for data centers. It is a liquidto-air heat exchanger and fan system that removes heat generated by rack-installed IT equipment. The
HPE Adaptive Rack Cooling System is connected to adjoining racks with baying brackets and front and
rear extensions, creating a cold aisle and hot aisle air plenum. Hot air from the IT exhaust is pulled
through the HPE Adaptive Rack Cooling System, cooled with the heat exchanger that is connected to
facility water, and the cooled air is then returned to the inlet of the servers. The HPE Adaptive Rack
Cooling System is offered in four configurations using either HPE ARCS 42U 600x1600mm Racks or HPE
ARCS 48U 600x1600mm Racks.
NOTE: The HPE Adaptive Rack Cooling System supports both HPE ARCS 42U and 48U 600x1600mm
Racks. For the following front elevation views, the HPE ARCS 48U 600x1600mm Rack is shown. The
HPE Adaptive Rack Cooling System is shown without doors for better viewing of components.
The thermal airflow illustrations show a top view of the HPE Adaptive Rack Cooling System and HPE
ARCS 42U/48U 600x1600mm Racks.

The airflow of the HPE Adaptive Rack Cooling System fully supports the industry standard front-to-back
cooling—cold air pulled into the front of the server and warm air expelled out the rear of the unit. All
devices receive adequate and evenly distributed cool air regardless of the mounting position within the
rack. The HPE Adaptive Rack Cooling System distributes precisely cooled and targeted air flow evenly
across the front of the IT equipment. The HPE Adaptive Rack Cooling System and rack extensions
channel warmed air from the rear of the IT equipment into the side-mounted or center-mounted HPE
Adaptive Rack Cooling System cooling unit. From there, it is cooled and recirculated to the front of the
equipment stack.
A 6U facade comes in the HPE ARCS 48U Air Rack Installation Kit, and you can place it on top of the
HPE Adaptive Rack Cooling System to make the HPE Adaptive Rack Cooling System the same height as
the HPE ARCS 48U 600x1600mm Racks. The following illustration shows a single-unit configuration with
the 6U facade in place on the HPE Adaptive Rack Cooling System and the HPE Adaptive Rack Cooling
System doors in place.

Configuration factors
Optimum environment and site preparation
CAUTION: Water quality that is out of spec may cause decreased cooling capacity or disruption in
service. The facility water supplied to the HPE Adaptive Rack Cooling System must meet the
guidelines stated in this manual. The HPE Adaptive Rack Cooling System warranty does not cover
damage caused by facility water that does not meet specifications.
To provide optimum performance with minimum maintenance, your site must meet environmental
requirements. The HPE Adaptive Rack Cooling System is intended to be installed in an indoor location
that is temperature controlled and relatively free of conductive contaminants.
To route water lines to your HPE Adaptive Rack Cooling System, use one of the following methods:
• Through an opening in the raised floor
• Through the top of the HPE Adaptive Rack Cooling System
Safety information
The HPE Adaptive Rack Cooling System is rated at a maximum facility pressure of 8 bar (116 PSI).
If valves are installed on the external pipe work that could potentially trap fluid inside the HPE Adaptive
Rack Cooling System, special precautions must be taken. To prevent severe plumbing failure due to
extreme pressure, use an expansion tank with a preinstalled safety valve in the plumbing circuit
connected to the unit.
WARNING: This equipment must be installed in a restricted access area. The equipment is not to
be accessible to persons (including children) with reduced physical, sensory, or mental capabilities,
or a lack of experience and knowledge, unless they have been given supervision or instruction. Only
authorized technicians trained by Hewlett Packard Enterprise should attempt to repair this
equipment. All troubleshooting and repair procedures are detailed to allow only subassembly- or
module-level repair. Because of the complexity of the individual boards and subassemblies, no one
should attempt to make repairs at the component level or to modify any printed wiring board.
Improper repairs can create a safety hazard.

Installing the HPE Adaptive Rack Cooling System
Procedure
1. Read the unpacking instructions on the HPE Adaptive Rack Cooling System packaging material.
WARNING: The HPE Adaptive Rack Cooling System is shipped on a pallet and weighs
approximately 645 kg (1,423 lb) by itself or 732 kg (1,614lb) including packaging. Hewlett
Packard Enterprise recommends hiring professional movers to move the unit, remove the HPE
Adaptive Rack Cooling System from the pallet, and move the HPE Adaptive Rack Cooling
System to the final location.
2. Using four or more people and the ramps that came with the HPE ARCS 42U/48U 600x1600mm
Rack, remove the HPE Adaptive Rack Cooling System from the pallet.
3. Roll the HPE Adaptive Rack Cooling System to the final location.
CAUTION: Before attaching the hoses to the HPE Adaptive Rack Cooling System, verify that
the water supply and return are closed. Water that leaks into the unit can cause significant
damage.
4. Install the hoses, differential pressure tube, and Panduit boots.
5. To level the HPE Adaptive Rack Cooling System:
a. Remove the screws from the fan housing.
b. Unplug the fan communication and power cables.
c. Remove the lower fan from the rack.
CAUTION: Use a minimum of two people to manually move the fan.
d. Adjust the leveling feet using a bubble level.
