Overview
Introduction
The HP mc-Series 5042 Rack is an air and water heat exchanger that removes high levels of excess heat
generated by equipment installed in HP racks. The installed equipment takes in cold air through the front of
the closed MCS 5042 and uses the air for internal cooling. After the air has been warmed, the MCS 5042
expels the air through the rear vents.

Configuration factors
Optimum environment and site preparation
CAUTION: Contaminated water might cause decreased cooling capacity or disruption in
service. The water flowing into the MCS 5042 unit must meet the guidelines stated in the HP
mc-Series 5042 Rack Site Preparation Guide. The MCS 5042 warranty does not cover damage
To provide optimum performance with minimum maintenance for your unit, environmental requirements must
be met.
The HP mc-Series 5042 Rack Site Preparation Guide provides information about planning your unit
configuration efficiently and organizing your site location before delivery of your MCS 5042 unit.
To locate the latest version of the HP mc-Series 5042 Rack Site Preparation Guide:
1. Go to the HP website (http://www.hp.com/go/rackandpower).
2. Select Rack and Rack Options.
3. Select Modular Cooling System.

caused by contaminated water.
IMPORTANT: Before you begin the installation process, review the HP mc-Series 5042 Rack Site
Preparation Guide.
6. Select and download the HP mc-Series 5042 Rack Site Preparation Guide.
To route water lines to your MCS 5042 unit, use one of the following methods:
• Through an opening in the raised floor
• Lying on top of the floor
• Through the top of the MCS 5042 unit
For more information on routing the water lines, see the HP mc-Series 5042 Hook Up Kit Installation
Instructions.
Safety information
The HP mc-Series 5042 Rack is tested to the maximum pressure (PS) of 8 bar (116 PSI) without fluid trapped
inside by closed, external valves.
If valves are installed on the external pipe work that could potentially trap fluid inside the MCS 5042 unit,
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.
