Abstract
This document outlines recommended practices for facility planning and preparation for the HP
Modular Cooling System (HP MCS) as used with the HP 10000 G2 Series Rack Model 10642 G2.
HP MCS Product overview
The HP MCS (Figure 1) cools the warm air that is generated by equipment installed in a 10642 G2
rack. The MCS unit is designed for high-density server and blade deployments. The horizontal air flow
of the MCS unit distributes cooled air uniformly throughout the complete height of the enclosure (i.e.,
all devices receive adequate and evenly distributed cool air regardless of their mounting position
within the enclosure).
Figure 1. HP 10642 G2 Rack with MCS
The HP MCS can be populated with the following HP products:
• HP ProLiant servers
• HP BladeSystem servers
• HP NonStop servers
• HP Integrity servers
• HP StorageWorks MSA, EVA and XP products
• HP rack mount power protection products
• HP rack mount switches
• HP rack mount monitors
• Third party IT equipment that conforms to 19”standard rack
1

The MCS unit cools and circulates air through the 10642 G2 rack as outlined in the following steps
(Figure 2):
1. The rack-mounted components in the 10642 G2 rack receive cooled air from the MCS unit. The
cooled air provides cooling for the components.
2. As the components warm the air, the warm air is expelled through the MCS heat exchangers
located at the rear of the MCS unit.
3. Warmed air is channeled back into the MCS unit.
4. The air is cooled and then re-circulated to the front of the rack.
Figure 2. MCS cooling process
Table 1 lists the key features of the HP MCS.
Table 1. HP MCS key features
Feature Description
Cooling Capacity of up to 35
kilowatts (kW)
Supports a maximum configuration of blade servers, which requires a power load of
approximately 35 kW. The HP MCS provides 2,700 cubic-feet-per-minute (CFM) of
cool air distributed along the full height of the rack.
Power Input Redundancy Automatically detects power failure and switches to alternate source.
Environmental Control and Safety Provides a full range of monitoring systems, including environmental control of the
cooled air temperature being placed in front of the servers. The heat exchanger units
features safety quick disconnect valves that prevent chilled water leakage during
service.
Hot-swappable components Fans and heat exchangers can be replaced while the unit is operating providing
greater flexibility for servicing the HP MCS.
CTO The MCS ships standard with a shock pallet that allows for factory integration of IT
equipment of up to 2000 Lbs. It can also ship empty to a VAR for integration and
then ship configured to the final destination.

HP Modular Cooling System Management Module
The MCS management module (Figure 3) is located inside of the MCS front door. The management
module can be accessed remotely through a web interface, and can be used to analyze, query, and
manage various measurements in the MCS unit. If a parameter is out of the specified threshold, either
a warning or alarm message displays on the operator display and on the web interface.
Figure 3. MCS management module
MCS deployment considerations
The following sections describe components and options available for the MCS that may be necessary
to achieve safety, regulatory compliance, or functionality requirements.
Levels of HP MCS security
Either of the following conditions may be necessary for compliance with certain safety certifications:
• The HP MCS must be located in a restricted access area that is only accessible to trained personnel.
-Or-
• The HP MCS must be configured with lockable hardware.
HP MCS front doors, rear doors, and side panels support this locking requirement. Rear split doors
are standard on the MCS.
5

6
HP MCS Front Doors
The MCS front door ships standard with every MCS unit. The MCS includes a front door with a
polycarbonite insert, which prevents chilled air from being re-circulated into the data center.
HP MCS Rear Doors
The MCS ships with solid rear doors as the standard configuration.
HP Side Panel Kit
Side panels ship as the standard configuration. Side panels aid in providing proper front to rear
airflow and a first level of security.
Important:
The MCS unit is not bayable and for proper air flow, the side panels should
not be removed from a MCS unit.
Stabilization for seismic activity
HP MCS installations in geographical areas where there is a risk of seismic activity require special
considerations for stabilization of the HP MCS.
Important:
The HP MCS is not a Zone 4 or OSHPOD solution.
An equipment integrator will need to determine the requirements for which, if any, ballast and
stabilizer kits are required. If the HP MCS is bolted to the floor or to an adjacent HP MCS that has
sufficient combined weight, additional stabilization products may not be required.
Space and cable management requirements
Important:
Roof-mounted fan kits should not be used in the HP MCS. The roof-mounted
fans are not compatible with the HP MCS air flow requirements.
Extension kits
Cables and equipment can be damaged in use or in shipping if there is insufficient room in the HP
MCS. Extensions can be used when additional room is required at the rear of the HP MCS to provide
adequate room for equipment and associated cables. The extension kit provides approximately 6.0
inches (155 mm) of additional space at the rear of the HP MCS.

7
Cable management kits
Due to the dynamic nature of the HP MCS environment, the cabling of systems has very few hard
rules. Cable management kits provide an easy way to organize and route cables within the HP MCS.
Several kits are available as options to assist with cabling requirements.
Additional information on cable management kits is available at: www.hp.com/products/rackoptions.
HP general guidelines for cable management are as follows:
• Rack Rear Extension kit (AF058A) is available to provide additional cabling space. The Rack Rear
extension kit will not affect the cooling capabilities of the MCS.
• For good visual reference, do not install cabling until all equipment has been installed in the HP
MCS.
• Avoid dressing cabling tightly over sharp edges of railing or panels.
• Avoid pinching of cables between components.
• Avoid tight bend radii. Cables should never be bent tight enough to cause a crease in the
sheathing. Fiber cables must not violate their minimum bend radius – no exceptions.
• When securing cables inside the HP MCS, the bundle should be dressed in such a way as to avoid
interference with installed components or HP MCS side panels or rails.
• When possible, use all cable management arms included in component kits.
• For components that must be movable while Powered On, ensure a full range of motion is possible
without cable interference or disconnect. Cables dressed on management arms must be secured
enough to prevent movement into interference or pinch areas, yet not so tight as to cause binding to
the arm.
• Separate power and signal cables as much as possible. For example, dress all signal cables on the
Left side of the HP MCS and all power cables on the Right side of the HP MCS.
• Ensure that cabling does not impede the airflow to the rack-mountable servers or increase the
internal HP MCS temperature beyond the specified maximum rating.
• Route all cables away from fans.
A list of available extension kits can be found at the main rack options product page at
www.hp.com/products/rackoptions.
Thermal requirements
Equipment that is exposed to excessive heat may not operate correctly and may experience
abnormally high failure rates. The air flows from the front to the rear of the HP MCS. HP recommends
that components only be installed on the front rails for proper airflow.
Automatic door opening mechanism
An Automatic Door Release Kit is included standard with every HP MCS. The kit ships in the
accessories box and is to be field-installed. The Automatic Door Release Kit is designed to swing the
HP MCS front and rear doors open in the case of a sudden increase in the temperature inside the HP
MCS. The open doors will allow the IT equipment to cool using the air from the datacenter.
Insulation Considerations
Flex-Hose exiting the MCS may be insulated to reduce condensation. The insulation should cover the
hose snugly with no gaps, with enough thickness as appropriate.

HP MCS assembly guidelines
Table 5 lists guidelines to follow when physically placing components in an HP MCS.
Table 5. HP MCS assembly guidelines
Component Guideline
Weight Sort all components by weight, placing the heaviest components at the bottom
of the HP MCS.
Keyboard/video/mouse
(KVM) switch box
Mount the switchbox either behind the keyboard or within a sidewall cavity to
provide a zero-U space solution.
Keyboard/integrated
keyboard monitor
Mount the keyboard or integrated keyboard monitor at a level that is in the
correct ergonomic position where your shoulders and neck are relaxed.
Monitor Ergonomic considerations should drive the placement of a monitor in the HP
MCS, whether it is a CRT or Flat-panel design. It is recommended to arrange the
screen or rack-mountable flat panel monitor, a minimum of 4U’s above the
keyboard tray. Most customers prefer placement of the video system high in the
HP MCS, especially in a full HP MCS, to allow easier access to serviceability of
other system components below it.
Additional resources
For further information regarding component placement, refer to the Important Safety Instructions that
are shipped with the HP MCS and the Safety and Comfort Guide - Precautions for Server and
Network Products located at www.hp.com (search for the safety and comfort guide).

HP MCS Installation and maintenance precautions
To reduce the risk of electric shock or damage to the equipment when installing, maintaining, or
servicing Enterprise products, observe the general precautions listed in Table 6.
Table 6. HP MCS installation and maintenance precautions
Precaution Description
Follow manufacturer instructions Always refer to the individual equipment installation instructions for any special
considerations when installing equipment in an HP MCS.
Be aware of power voltages and use
trained personnel
Some Enterprise products are capable of producing hazardous voltages and
hazardous energy levels. The installation of internal options and routine
maintenance and service of these products should be performed only by
individuals who are knowledgeable with the procedures, precautions, and
hazards associated with this type of equipment. Refer to the documentation
included with each product to determine whether it belongs in this category.
Secure all equipment Unless the equipment is installed in a restricted access area, HP MCS equipment
should be operated only with all enclosures in place and properly secured.
Always refer to the equipment installation guide and observe all applicable
warnings and precautions.
Provide overhead clearance for fire
sprinkler devices
A minimum clearance is required between the top of the HP MCS and any fire
protection sprinkler devices. Check your local building codes for details.
HP MCS side service access
The HP MCS does not provide full accessibility for servicing a rack-mountable component from the
side of the HP MCS unit; therefore, side serviceability may be limited for certain rack-mountable
components.
Moving an HP MCS on its casters
An HP MCS should be moved on its casters with care. Sudden stops, excessive force, and uneven
surfaces may cause the product to overturn. The HP MCS has casters which are fixed in the front and
swivel in the rear. Therefore, it is recommended and also easier to move the HP MCS with the back
as the leading edge. Roll the HP MCS with fixed casters first. When rolling the HP MCS, make sure to
push firmly on the doorframe and not the door mesh.
Important:
An HP MCS must be disconnected from water and power sources before
being moved.
Warning:
To reduce the risk of personal injury or damage to the equipment, do not
attempt to move large equipment alone. Obtain adequate assistance to
stabilize the HP MCS during movement or hire professional equipment
riggers.
Caution:
To reduce the risk of damage to the casters, make sure that the full weight
of the HP MCS rests on the leveling feet, and not on the casters. The casters
are designed only as an aid in moving the HP MCS into position. They are
not designed to support the weight of the rack, and the casters may
become damaged if relied on to support the HP MCS.

Connecting and disconnecting power to hot-pluggable power supplies
Observe the following guidelines when connecting and disconnecting power to the power supplies:
• Unplug the power cord before removing the power supply from the server.
• Install the power supply before connecting the power cord to the power supply.
• Do not overload the AC supply branch circuit that provides power to the HP MCS. The total HP
MCS load should not exceed 80 percent of the branch circuit rating.
Rack-mountable components
Because computer components are stacked vertically in an HP MCS, adhere to the following
precautions to ensure HP MCS stability:
• Load heavier components first and load the HP MCS from the bottom up.
• Allow a minimum clearance of 30 in. (762 mm) at the back of the HP MCS.
• Allow a minimum of 48 in. (1219.2 mm) clearance beyond the front of the HP MCS to permit
server installation and removal. This applies to both individual HP MCS installations as well as
when aligning HP MCSs in rows so that the front doors are facing each other. See Figure 4.
• Use caution when pressing the component rail release latches and sliding a component into the HP
MCS. The slide rails can pinch your fingers and cables.
Figure 4. HP MCS clearance (Minimum recommended front HP MCS space)
Warning:
To reduce the risk of personal injury or damage to the equipment, be sure
that the HP MCS is stabilized as follows:
• The leveling feet are extended to the floor.
• The full weight of the HP MCS rests on the leveling feet.
• Extend only one component at a time or the HP MCS may become unstable.
10

Aligning the HP MCS with HP 10000 Series racks
The HP MCS can be installed next to an existing or new row of HP 10000 Series racks. Based on the
facility design requirements, the cabinets can be arranged in a flus-front (Figure 5) or flush-rear
(Figure 6) configuration.
Figure 5. HP MCS arranged in a flush-front configuration with a row of 10000 Series racks (top view)
Figure 6. HP MCS arranged in a flush-rear configuration with a row of 10000 Series racks (top view)
Data Center planning and considerations
Environmental considerations
The data center must meet certain environmental conditions for the HP MCS implementation. The HP
MCS should be configured and arranged in a data center to ensure proper air flow. The HP MCS
should be installed in a protective environment that is not exposed to the elements.
Ensure that the data center meets the environmental guidelines outlined in the HP Modular Cooling
System Site Preparation Guide, available at:
http://h20000.www2.hp.com/bizsupport/TechSupport/DocumentIndex.jsp?contentType=SupportManual&lang
=en&cc=us&docIndexId=179111&taskId=101&prodTypeId=329290&prodSeriesId=1155256.
11

12
Slots, openings and perforations in the HP MCS (especially in doors) provide ventilation, reliable
operation, and prevent overheating and, therefore, should never be blocked or covered. To provide
proper front-to-back air flow, any open "U" space in the front of the HP MCS must be covered with a
HP 10000 Series Universal Filler Panel.
Caution:
Failure to cover open U spaces with blanking panels may result in improper
cooling that can lead to thermal damage.
Refer to the HP Modular Cooling System Site Preparation Guide for temperature and humidity
guidelines. For the HP Modular Cooling System Site Preparation Guide, go to
http://h20000.www2.hp.com/bizsupport/TechSupport/DocumentIndex.jsp?contentType=SupportManual&lang
=en&cc=us&docIndexId=179111&taskId=101&prodTypeId=329290&prodSeriesId=1155256.
Note:
Altitude derating of 1 Celsius for every 300 meters above sea level to a
maximum of 3,000 meters (1.8 Fahrenheit per every 1,000 feet up to a
maximum of 10,000 feet). No direct sustained sunlight.
Power considerations
Power is best managed within the HP MCS by the use of a power distribution unit (PDU). Depending
on the configuration, it may be necessary or desirable to use multiple PDUs to connect all devices
inside the HP MCS.
Each PDU should be connected to a dedicated (unshared) branch circuit that is suitably rated for the
continuous load of all the equipment connected to it. The total power load for a PDU should not
exceed 80 percent of the branch circuit rating.
If a PDU is not used, each piece of equipment within the HP MCS should be connected to a dedicated
branch circuit.
Power redundancy
High-availability Information Technology equipment such as servers and storage devices can be
configured with backup or redundant power sources and power supplies in either of the following
configurations:
• 1+1 design: Two power supplies can be provided where either power supply is capable of
sustaining the associated equipment’s power demand.
• N+1 design: Typically three power supplies are provided, requiring at least two to handle the
equipment’s power demand. If one fails, the other two remain on line with enough capacity to meet
the power demand.
It is important that the wiring and branch circuitry to each installation be suitably rated for the power
demand of the connected equipment. Routing the power through separate branch circuits, breaker
panels and PDUs is also recommended to provide additional redundancy.
Non-redundant
For equipment provided with a single source of power, all components should be connected to the
same power distribution device (PDU or UPS). The power distribution device should be suitably rated
for the connected load. If the total load exceeds the rating of the power distribution device, obtain a
suitably rated device or add a second power distribution device and divide the load equally between
the devices.

13
High line voltage versus low line voltage
HP recommends that rack-optimized equipment is installed for operating at high line voltage (200-
240V AC).
Note:
The HP MCS can only be operated using high line voltage; however, rack-
mounted components can be operated using either high line or low line
voltage.
All HP products that are optimized for rack mounting have wide-range power supply inputs designed
to operate at a voltage range of 100-240V.
Benefits that support high line voltage operation of an installation are as follows:
• Power supplies run more efficiently and waste less power when operating at 200-240V, thus saving
electrical power.
• Greater power capacity in a single HP MCS. For the same size circuit, almost twice the power can
be delivered to an HP MCS at high line versus low line. For example, a 115V 30A branch circuit
can deliver 3450VA to an HP MCS, while a 230V 30A branch can deliver 6900 VA to an HP
MCS.
• Some products require 200-240V input power to operate at their full-rated capacity.
• Power supplies run cooler at higher input voltages and therefore will last longer and improve
overall availability. Also, because they run cooler, they produce less waste heat contributing to
lower cooling costs.
• Keeping input currents lower allows the use of smaller, more standardized power connections.
Grounding and Earth leakage current
For proper operation and safety, HP MCS components must be properly grounded in accordance
with any local and regional building codes. Furthermore, make sure that all power distribution
devices used in the installation, such as branch wiring and receptacles, are Listed or Certified
grounding-type devices.
The HP MCS is grounded. Ensure that the rack-mounted components are grounded as follows:
• For UPS products and PDUs that have permanently attached AC power cords or are directly wired
to the building power, the total combined leakage current should not exceed 5 percent of the total
input current required for the connected products.
• For UPS products and PDUs that have detachable AC power cords, the total combined leakage
current should not exceed 3.5 mA per PDU or UPS.
Additional resources
A power calculator is available at the following link:
http://h30099.www3.hp.com/configurator/calc/Power Calculator Catalog.xls.
Also available is a ProLiant Rack/Site Installation Utility for purposes of reviewing the server loading
to determine the number of power supplies for the power supplies to be redundant and approximate
the electrical and heating load per server for facilities planning. Please see the following:
http://h30099.www3.hp.com/configurator/calc/Site Preparation Utility.xls.
There is also a quick reference power cord matrix available at the following:
ftp://ftp.compaq.com/pub/products/servers/proliantstorage/power-protection/powercordmatrix.pdf.

Equipment clearance and floor loading
A minimum clearance of 48 inches in front of a configured HP MCS and 30 inches to the rear of a
configured rack is recommended. All buildings and raised computer room floors are engineered to
provide a specific floor loading.
Warning:
When configuring a solution, make sure that the floor loading
specifications are followed. Failure to do so may result in physical injury or
damage to the equipment and the facility.
Figure 7 illustrate the foot print of an HP MCS.

Figure 9. HP MCS door clearance
Note:
There is a potential for front or rear door swing interference when
arranging the HP MCS immediately next to an HP 10000 Series rack. It
may be necessary for the removal of a rack door for full, unimpeded access
to the adjacent rack.
Qualified shipping
The HP MCS ships pre-installed to a 10000 G2 Series rack. The MCS is CTO-capable for up to 2000
Lbs and ships standard with a shock pallet. The MCS can be used to factory-integrate IT equipment at
Factory Express or other configuration services.
Standard shipping pallet
The HP MCS ships on a special wooden shock pallet with plastic shrink-wrap around the HP MCS.
Component installation may occur at the customer site, at a VAR or integrator, or at HP Factory
Express.
Note:
Wooden components of the pallets have been properly treated to comply
with the pest-free certifications required by foreign countries.

Site preparation for receiving the HP MCS
To determine if an HP MCS is suitable for shipment, be sure to examine the receiving facility site
conditions. Circumstances requiring special handling of the HP MCS, such as inadequate door height
clearance or having to move the HP MCS in a horizontal orientation, may justify a decision to install
components after the moving process.
The specialized, air-ride, padded-van carriers usually have the ability to perform site surveys.
Among other elements, the site survey should address the following in general terms:
• What are the hours the facility is open for deliveries? Can delivery be done during the day during
normal business hours?
• Are appointments required?
• Does the receiving dock require union labor? Is there a site contact?
• Are there any security or building access issues? Is there a site contact?
• Does the facility have a dock? Is the delivery dock a standard raised dock? Can a 48-foot trailer
gain access? Are there any restrictions on the size, length, width or height, of the truck permitted?
• On what floor in building will the equipment be installed? This information is in consideration of
height and width clearances along the way: doors, light fixtures, cable trays, sprinkler heads,
elevators, etc.
• What are the door height clearances (width and height) for freight elevators, doorways, or other
obstacles?
• If equipment is not going on the first floor, is there an elevator? If yes, what is the weight capacity
of the elevator?
• Is the path from the loading dock to the computer room robust enough to support the weight of the
configured HP MCS?
• Is there a delivery/unpacking/staging area? Does the customer allow cardboard boxes and/or
other packing material in the computer room? Does the customer have a detrash requirement, for
example is complete trash removal one or two days after install required?
• Is there a raised floor or are there any thresholds of concern? If there is a raised floor, how deep? Is
there a ramp? What sort of equipment maneuvering is required to gain access? Are there special
equipment needs, for example, will any stair walkers, lifters, cranes, ramps, steel plates or floor
covers be required to place the equipment in the computer room?
• Will the HP MCS be removed from the pallet at a location other than the final installation location?
• Is movement across rough surfaces likely?
• Refer to the HP Modular Cooling System Site Preparation guide at www.hp.com/go/mcs for
complete information on deploying the HP MCS.
Door Height Clearances
HP does not advocate tipping loaded the HP MCS to navigate height restricted doorways. The HP
recommended procedure is to first depopulate the HP MCS and then tip the HP MCS to pass the
restricted doorway. Once the HP MCS is positioned in its final location, it can be repopulated. This
will ensure that HP MCS stability is maintained by not tipping a heavily loaded HP MCS.
Depopulating the HP MCS also ensures that the integrity of the components in the HP MCS are not
compromised by tipping.
Note:
An empty HP MCS can be tipped if necessary to clear a doorway.

18
If you have restricted height doorways, you have several alternatives for purchasing HP factory
racked solutions that can accommodate the height of the doorways without the need to depopulate
the HP MCS.
If you have restricted doorways:
• You can order racked solutions in an appropriate sized HP MCS that can be accommodated by the
doorways. Choose the rack size that best meets your datacenter needs while at the same time
being able to pass all doorways on the path to the HP MCS final location.
• An HP MCS that is unable to pass fully loaded through the doorway, options include:
– Ordering an empty HP MCS and purchasing installation services from HP Services.
– For BCS midrange servers with included installation services, you can order an empty HP MCS
and order the server with the field installation option.
• With included site preparation service, the best way to locate the system to its final location is
recommended.
Airfreight
Because the HP MCS cannot be safely tipped or placed on its side during transit or storage, air cargo
doors must have height sufficient for the HP MCS to be loaded and removed without tipping. Consult
your freight forwarder for available aircraft configurations that satisfy your particular HP MCS height.
International Air Transport Association labeling
Typical HP products that are classified as Magnetized Material are those with arc-welded frames that
contain a large mass of ferrous metal. For example, most HP MCSs or cabinets will usually test in the
low to mid-range of the regulatory limits and be classified as Magnetized Material. In the past, high-
end (floor standing) disk drives were regulated due to the large motors they contained; however, as
the size of the drives has been reduced, so has the size of the motors. Disk drives alone are no longer
regulated, but may be loaded into an HP MCS that is.
Magnetized Material are regulated as Dangerous Goods under Class 9, “Miscellaneous Dangerous
Goods,” and have been assigned the United Nations identification number, UN2807. These goods
are only regulated when transported by air due to their potential for interference with aircraft
instrumentation. Shipments must be properly marked, labeled and documented to be legally accepted
by an air carrier for transport.
For more specific details of how and why this requirement process is managed, please refer to the
following URL: www.iata.com.
In all cases of air shipments, a Shipper Declaration is required (see Figure 11). This sample is an
internal HP document. If access is needed, please ask your local HP service representative to contact
the Rack Program management organization within HP.
