Facility planning for implementation 79

• Be sure facility managers understand that additional load is being added to the facility water supply. Be

aware that the heat load being added might have an effect on other components being cooled by the

facility water plant.

CAUTION: The water supply system feeding the MCS-200/100 must be capable of withstanding

deadheading (operating with a closed line) and operation with rapid and frequent changes in

flow requirements, including long periods with zero water flow.

Plumbing materials to avoid

Do not use the following materials with a closed water system:

• Oxidizing biocides

• High zinc and brass components

• Non-stainless steel iron components

The temperatures stated are for an elevation of 0 to 5000 ft above sea level. The maximum operating

temperatures must be de-rated by 1ºC per 1000 ft for locations 5000 to 10,000 ft above sea level.

Control system

The MCS-200/100 includes a control system that constantly monitors the air temperatures, water

temperatures, and flow rate. The management module attempts to maintain the air temperature at the target

set point. If the set point temperature cannot be maintained, the HP Modular Cooling System 200/100

management module will generate an alarm and notify facility management systems, as configured.

For site evaluations and technical consulting services for your site, see the HP Modular Cooling System

200/100 User Guide.

Before installing and running active components

CAUTION: If the MCS-200/100 unit runs in manual mode for a period of time without an

adequate heat load being generated by servers or other computing/networking devices, excess

condensation could occur within the cabinet or system.

Prior to starting up any active components mounted in the MCS-200/100 rack, such as servers, storage

devices, and so on, the following actions must be performed:
