Overview
Product overview
The HPE Adaptive Rack Cooling System is a supplemental cooling system for data centers. It is a liquid-
to-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.

Option Kits
HPE ARCS Water Hook-Up Kit
Hewlett Packard Enterprise recommends using the HPE Adaptive Rack Cooling SystemWater Hook-Up
Kit to connect the HPE Adaptive Rack Cooling System to a facility water supply. Each kit includes two
hose assemblies with 2-inch sanitary flange connections that are required for connecting the facility
supply and return lines to the main inlet and outlet connections of an HPE Adaptive Rack Cooling
System. One Water Hook-Up Kit is required for each HPE Adaptive Rack Cooling System.
NOTE: To properly connect the Water Hook-Up Kit, the facility plumbing connection must be a 2-inch
flange fitting.
NOTE: The illustration is not drawn to scale. The actual length of the hoses is approximately 1.83 m (6 ft).
