Introduction ............................................................................................................................................. 5

Introduction

The HP Modular Cooling System is an air and water heat exchanger that removes high levels of excess heat generated by equipment installed in HP 10642 G2 Racks. The installed equipment takes in cold air through the front of the closed MCS unit, uses the air for internal cooling, and then expels it through the rear vents after it has been warmed. The air is then recycled through the MCS unit.

Optimum environment and site requirements

CAUTION: Contaminated water may cause decreased cooling capacity or disruption in

service. It is important that the water flowing into the MCS unit meets the guidelines stated in the HP Modular Cooling System Site Preparation Guide. Damage caused by contaminated water is not covered by the MCS unit warranty.

IMPORTANT: You must read the HP Modular Cooling System Site Preparation Guide before

beginning the installation process.

Specific environmental requirements must be met to provide optimum performance with minimum maintenance for your unit.

To help you learn about these requirements and to plan your unit configuration more efficiently, HP provides the HP Modular Cooling System Site Preparation Guide.

Site preparation

Installing the MCS unit

WARNING: The MCS unit and rack are shipped together on a heavy duty shock pallet

weighing approximately 2000 lb. HP recommends hiring professional movers to move the heavy duty shock pallet, and then remove the MCS unit and rack from the pallet and into to the

1. Read the unpacking instructions on the MCS packaging material.

final location.

CAUTION: Contaminated water may cause decreased cooling capacity or disruption in

IMPORTANT: You must read the HP Modular Cooling System Site Preparation Guide before

beginning the installation process.

IMPORTANT: Be sure to install the HP Water Hook-up Option Kit before connecting the In and

Out water hoses to the water lines.

2. With four or more people, carefully remove the MCS unit and rack from the pallet.

3. Roll the MCS unit and rack approximately 91 cm (3 ft) in front of the final location.

4. Loosen the jam nut, and raise the unit by lowering the two rear leveling feet on both the MCS unit

and the rack until the rear caster plate can be removed.

Installation 10

Remove the rear caster plate.

6. Lower the unit by raising the two rear leveling feet on both the MCS unit and the rack so that the

MCS unit can move freely on the remaining casters.

Installation 11

Roll the MCS unit and rack into the final location while guiding the In and Out water hoses through the raised floor opening.

8. Using a bubble level, adjust the leveling feet to level the MCS unit and rack.

Installation 12

Install and route the two drain hoses to the drain collection system catch basin.

a. Install the blue drain hose by inserting one end of the hose into the plastic collar quick connect

on the condensation pump, and then route the other end into either the condensation return line or the gravity drain collection system catch basin.

Installation 13

Install the clear drain hose by inserting one end of the hose into the condensation collection pan, and then route the other end into the gravity drain collection system catch basin.

NOTE: Position the gravity drain collection system below the condensation collection pan,

allowing gravity to draw the water out of the condensation collection pan and into the gravity

drain collection system catch basin.

11. Guide the other end of the network cable through the bottom of the MCS unit.

IMPORTANT: Do not connect the power cords into a power supply.

12. Plug the primary power cord into the power connector on the left.

Installation 14

WARNING: To reduce the risk of electric shock or damage to the equipment:

• Do not disable the power cord grounding plug. The grounding plug is an important safety

feature.

• Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at all

times.

• Unplug the power cord from the power supply to disconnect power to the equipment.

• Do not route the power cord where it can be walked on or pinched by items placed against

it. Pay particular attention to the plug, electrical outlet, and the point where the cord extends from the storage system.

13. If a secondary power cord is being used, plug it into the power connector on the right.

14. Guide the other end of the power cords through the bottom of the MCS unit.

IMPORTANT: Be sure to flush the prearranged facility water lines of debris prior to connecting

them to the In and Out hoses.

15. Connect the In and Out water hoses to the prearranged facility water lines.

Installation 15

16.

Turn on the water to the prearranged facility water lines.

17. (Optional) Remove the two screws from the bottom brackets on the MCS frame.

18. (Optional) Align the access panel with the two holes from step 17.

19. (Optional) Secure the access panel to the MCS frame using the two screws you removed in step 17.
