Site and hardware physical planning overview

Successful installation requires effective planning of your physical and operational environment. You are
the most valuable resource in site planning because you know where and how your system, and the
devices that are attached to it, are used.

Site preparation for the complete system is the responsibility of the customer. The primary task of your
site planner is to ensure that each system is installed so that it can operate and be serviced efciently.

This topic collection provides the basic information that you need to plan for your system installation. It
provides an overview of each planning task and valuable reference information useful throughout the
performance of these tasks. Depending on the complexity of the system that you ordered and your
existing computing resource, you might not need to complete all the steps noted here.

First, with the help of your systems engineer, sales representative, or with the help of those coordinating
your installation, list the hardware for which you need to plan. Use the summary of your order to help you
when you make your list. This list is now your “To Do” list. You can use the Planning task checklist to
assist you.

While you are responsible for planning, vendors, contractors, and your sales representative are also
available to help with any aspect of the planning. For some system units, a customer service
representative installs your system unit and veries correct operation. Some system units are considered
customer-installed. If you are not sure, check with your sales representative.

The physical planning section of this topic collection provides the physical characteristics of many system
units, and associated products. For information on products not included in this topic collection, contact
your sales representative or your IBM reseller.

Before you proceed with planning, ensure that the hardware and software you chose meets your needs.
Your sales representative is available to answer questions.

While this information is for hardware planning, the system memory and disk storage needed are a
function of the software to be used, therefore some things to consider are listed below. Information on
software products is generally in or with the software licensed program itself.

In assessing the adequacy of hardware and software, consider the following guidelines:

• Available disk space and system memory for accommodating software, online documentation, and data
(including future growth needs resulting from extra users, more data, and new applications).

• Compatibility of all devices.

• Compatibility of software packages with each other and with the hardware conguration.

• Adequate redundancy or backup capabilities in hardware and software.

• Software portability to the new system, if necessary.

• Prerequisites and corequisites of chosen software are satised.

• Data to be transferred to the new system.

Notes:

1. Redundancy is supported. The 9008-22L, 9009-22A, and 9223-22H have a maximum of two power
supplies, but can operate on one power supply. The 9009-41A, 9009-42A, and 9223-42H have a maximum
of four power supplies, but can operate on two power supplies.

2. The power supplies automatically accept any voltage with the published, rated-voltage range. If multiple
power supplies are installed and operating, the power supplies draw approximately equal current from the
utility (electrical supply) and provide approximately equal current to the load.

3. Power draw and heat load vary greatly by conguration. When you plan for an electrical system, it is
important to use the maximum values. However, when you plan for heat load, you can use the IBM Systems
Energy Estimator to obtain a heat output estimate based on a specic conguration. For more information,
see The IBM Systems Energy Estimator website.

4. To calculate the amperage, multiply the kVA by 1000 and divide that number by the operating voltage.

Environment requirements

Notes:

1. IBM provides the recommended operating environment as the long-term operating environment that
can result in the greatest reliability, energy efciency, and reliability. The allowable operating
environment represents where the equipment is tested to verify functionality. Due to the stresses
that operating in the allowable envelope can place on the equipment, these envelopes must be used
for short-term operation, not continuous operation.

2. Must derate the maximum allowable temperature 1°C (1.8°F) per 175 m (574 ft) above 900 m (2953
ft) up to a maximum allowable elevation of 3050 m (10000 ft).

3. The minimum humidity level is the larger absolute humidity of the -12°C (10.4°F) dew point and the
8% relative humidity. These levels intersect at approximately 25°C (77°F). Below this intersection,
the dew point (-12°C) represents the minimum moisture level, while above it, the relative humidity
(8%) is the minimum. For the upper moisture limit, the limit is the minimum absolute humidity of the
dew point and relative humidity that is stated.

4. The following minimum requirements apply to data centers that are operated at low relative
humidity:

• Data centers that have do not have ESD floors and where people are allowed to wear non-ESD

shoes might want to consider increasing humidity given that the risk of generating 8 kV increases
slightly at 8% relative humidity, when compared to 25% relative humidity.

• All mobile furnishings and equipment must be made of conductive or static dissipative materials

and be bonded to ground.

• During maintenance on any hardware, a properly functioning and grounded wrist strap must be

used by any personnel who comes in contact with information technology (IT) equipment.

5. Equipment that is removed from the original shipping container and is installed, but is powered
down. The allowable non-operating environment is provided to dene the environmental range that
an unpowered system can experience short term without being damaged.

server installation. This IBM system is available in racks with optional acoustical door features that
can help reduce the noise that is emitted from this system. The actual sound pressure levels in your
installation depend upon various factors, including the number of racks in the installation; the size,
materials, and conguration of the room where you designate the racks to be installed; the noise
levels from other equipment; the room ambient temperature, and employees' location in relation to
the equipment. Further, compliance with such government regulations also depends upon various
extra factors, including the duration of employees' exposure and whether employees wear hearing
protection. IBM recommends that you consult with qualied experts in this eld to determine
whether you are in compliance with the applicable regulations.

Notes:

1. The power supplies for AC or DC voltage do not change. Only the power chunnel is different. The power
chunnel uses internal cables to carry power from the rear of the system node to the power supplies that are
in the front of the system node.

2. All measurements made in conformance with ISO 7779 and declared in conformance with ISO 9296.

3. AC and HVDC power supplies cannot be mixed in the same server or I/O drawer. IBM recommends that AC
products and HVDC products with HVDC PDUs are installed in separate racks. However, AC and HVDC
products can be supported in the same rack if all grounding (earthing) is done in accordance with the
applicable electrical code or codes. IBM provides documentation for different AC and HVDC products about
the disconnecting means for service. If a different disconnecting means is to be used for service of the
equipment in a rack with AC-powered and DC-powered products, the disconnecting means must be made
clear to service.

This feature provides a top-mounted, dual DC power distribution panel for a rack that can contain varying
quantities of central processing unit (CPU) drawers, storage subsystems, or both. Up to two DC H80
systems or two DC M80 systems are supported, in addition to up to four DC storage subsystems. This
feature is built without attached power cables. It comes with a series of power connectors that are built
into its rear bulkhead. The appropriate DC power cables are included with supported drawer systems and
plug into the power connectors at the rear of the 6117 PDP.

FC EPB8 (-48 V dc power distribution panel (PDP))

This feature provides a top-mounted -48 V dc PDP for model 7014-T00 racks that can contain varying
quantities of drawers, storage subsystems, and OEM equipment. This feature is preinstalled on the 7014­T00 rack. The PDP sits on top of the rack and does not take up any EIA space. The PDP supports
redundant power with a split A and B side. Each side can support up to 10 circuit breakers that are rated 5

- 90 amperes with a maximum load of 600 amperes. FC EPB8 does not include circuit breakers or DC
power cables. The circuit breakers and associated DC power cables are typically supplied with IBM
products. For OEM products, you must provide the applicable circuit breakers and DC power cables.

Note: Front doors are optional on the 7014-T00 rack.

Heat exchanger performance

A heat removal of 100% indicates that an amount of heat that is equivalent to that generated by the
devices has been removed by the heat exchanger and the average air temperature leaving the heat
exchanger is identical to that entering the rack (27°C (80.6°F) in this example). Heat removal in excess of
100% indicates that the heat exchanger not only removed all of the heat that was generated by the
devices, but further cooled the air so that the average air temperature that is leaving the rack is actually
lower than air temperature that is entering the rack.

To help maintain optimum performance of the rear door heat exchanger and provide proper cooling for all
rack components, you must take the following precautions:

• Install ller panels over all unoccupied bays.

• Route signal cables at the rear of the rack so that they enter or exit the cabinet through the top and
bottom air baffles.

• Bundle signal cables together in a rectangle so that the upper and lower air-baffle sliders are closed as
far as possible. Do not bundle signal cables together in a circular formation.

Water specications for the secondary cooling loop

Important:

48

Power Systems: Site and hardware planning

The water that is being supplied to the heat exchanger must meet the requirements that are described in
this section.

Do not use glycol solutions because they can adversely affect the cooling performance of the heat
exchanger.

Cooling loop requirements

A secondary cooling loop, separate from the main site cooling loop, is required for the rear door heat
exchanger. Cooling distribution units are available from suppliers such as Coolcentric.

The secondary cooling loop must meet the requirements that are outlined in the water chemistry

specication. For more information about water chemistry requirements, see Water cooling system
specication and requirements.

Water-supply requirements for secondary loops

Learn about the specic characteristics of the system that supplies the chilled conditioned water to the
heat exchanger.

Temperature:

The heat exchanger and its supply hose and return hoses are not insulated. Avoid any condition that
might cause condensation. The temperature of the water inside the supply hose, return hose, and
heat exchanger must be kept above the dew point of the location where the heat exchanger is being
used.

Attention:

chilled water can be as cold as 4°C - 6°C (39°F - 43°F).

Important:

The system that supplies the cooling water must be able to measure the room dew point and
automatically adjust the water temperature accordingly. Otherwise, the water temperature must be
above the maximum dew point for that data center installation. For example, the following minimum
water temperature must be maintained:

• 18°C plus or minus 1°C (64.4°F plus or minus 1.8°F). This specication is applicable within an
ASHRAE Class 1 Environmental Specication that requires a maximum dew point of 17°C (62.6°F).

• 22°C plus or minus 1°C (71.6°F plus or minus 1.8°F). This specication is applicable within an
ASHRAE Class 2 Environmental Specication that requires a maximum dew point of 21°C (69.8°F).

See the ASHRAE document Thermal Guidelines for Data Processing Environments.

Pressure:

The water pressure in the secondary loop must be less than 690 kPa (100 psi). Normal operating
pressure at the heat exchanger must be 414 kPa (60 psi) or less.

Flow rate:

The flow rate of the water in the system must be in the range of 23 - 57 liters (6 - 15 gallons) per
minute.

Pressure drop versus flow rate for heat exchangers (including quick-connect couplings) is dened as
approximately 103 kPa (15 psi) at 57 liters (15 gallons) per minute.

Typical primary chilled water is too cold for use in this application because building

Water volume limits:

The heat exchanger holds approximately 9 liters (2.4 gallons). Fifteen meters (50 ft) of 19 mm (0.75
in.) supply and return hoses hold approximately 9.4 liters (2.5 gallons). To minimize exposure to
flooding in the case of leaks, the entire product cooling system (heat exchanger, supply hose, and
return hose), excluding any reservoir tank, must have a maximum 18.4 liters (4.8 gallons) of water.
This is a cautionary statement, not a functional requirement. Also, consider using leak detection
methods on the secondary loop that supplies water to the heat exchanger.

Site and hardware planning

49

Air exposure:

The secondary cooling loop is a closed loop, with no continuous exposure to room air. After you ll the
loop, remove all air from the loop. An air bleed valve is provided at the top of a heat exchanger
manifold for purging all air from the system.

Water delivery specications for secondary loops

Learn about the various hardware components that make up the delivery system secondary loop that
provides the chilled, conditioned water to the heat exchanger. The delivery system includes pipes, hoses,
and the required connection hardware to connect the hoses to the heat exchanger. Hose management
can be used in raised-floor and non-raised-floor environments.

The heat exchanger can remove 100% or more of the heat load from an individual rack when it is running
under optimum conditions.

The primary cooling loop is considered to be the building chilled-water supply or a modular chiller unit.
The primary loop must not be used as a direct source of coolant for the heat exchanger.

Procurement and installation of the components that are needed to create the secondary cooling loop
system are required for this design and are your responsibility. The main purpose is to provide examples
of typical methods of secondary loop setup and operating characteristics that are needed to provide an
adequate and safe supply of water to the heat exchanger.

Attention:

The overpressure safety device must meet the following requirements:

• Comply with ISO 4126-1.

• Be installed so that it is easily accessed for inspection, maintenance, and repair.

• Be connected as close as possible to the device that it is intended to protect.

• Be adjustable only with the use of a tool.

• Have a discharge opening that is directed so that discharged water or fluid does not create a
hazard or be directed toward any person.

• Be of adequate discharge capacity to ensure that the maximum working pressure is not
exceeded.

• Be installed without a shutoff valve between the overpressure safety device and the protected
device.

Read the following guidelines before you design the installation:

• A method for monitoring and setting the total flow rate that is delivered to all of the heat exchangers is
required. This can be a discrete flowmeter that is built into the flow loop or a flowmeter within the
secondary loop of the coolant distribution unit (CDU).

• After you set the total flow rate for all of the heat exchangers by using a flowmeter, it is important to
design the plumbing so that it provides the flow rate that you want for each heat exchanger and
provides a way to verify the flow rate. Other methods, such as inline or external flowmeters, can provide
a more accurate method for setting the flow rate through the individual shutoff valves.

Manifolds and piping:

Manifolds that accept large-diameter feed pipes from a pump unit are the preferred method for
splitting the flow of water to smaller-diameter pipes or hoses that are routed to individual heat
exchangers. Manifolds must be constructed of materials that are compatible with the pump unit and
related piping. The manifolds must provide enough connection points to allow a matching number of
supply and return lines to be attached, and the manifolds must match the capacity rating of the
pumps and the loop heat exchanger (between the secondary cooling loop and the building chilled­water source). Anchor or restrain all manifolds to provide the required support to avoid movement
when quick-connect couplings are connected to the manifolds.

Example of manifold supply pipe sizes:

50

Power Systems: Site and hardware planning

• Use a 50.8 mm (2 in.) or larger supply pipe to provide the correct flow to three 19 mm (0.75 in.)
supply hoses, with a 100 kW coolant distribution unit (CDU).

• Use a 63.5 mm (2.50 in.) or larger supply pipe to provide the correct flow to four 19 mm (0.75 in.)
supply hoses, with a 120 kW CDU.

• Use an 88.9 mm (3.50 in.) or larger supply pipe to provide the correct flow to nine 19 mm (0.75 in.)
supply hoses, with a 300 kW CDU.

To stop the flow of water in individual legs of multiple circuit loops, install shutoff valves for each
supply and return line. This provides a way to service or replace an individual heat exchanger without
affecting the operation of other heat exchangers in the loop.

To ensure that water specications are being met and that the optimum heat removal is taking place,
use temperature and flow metering (monitoring) in secondary loops.

Anchor or restrain all manifolds and pipes to provide the required support and to avoid movement
when quick-connect couplings are being attached to the manifolds.

Flexible hoses and connections to manifolds and heat exchangers:

Pipe and hose congurations can vary. You can determine the best conguration for your installation
by analyzing the needs of your facilities, or a site preparation representative can provide this analysis.

Flexible hoses for the cold-water supply and warm water return are provided with the delivery of the
rear door heat exchanger (allowing needed movement for opening and closing the rack rear door). The
customer needs to supply a 2.54 cm (1 in.) female national pipe thread (NPT) tting for each supply
and return hose connection to the facility. The IBM supplied hoses contain the quick connect ttings
to mate to the ttings on the rear door heat exchanger.

Use solid piping or tubing that has a minimum inner diameter of 19 mm (0.75 in.) and the fewest
possible joints between a manifold and a heat exchanger in each secondary loop.

Floor cutout

Racks with water hoses and power cords that exit from the bottom of the rack require a floor tile cutout of
at least 30.48 cm (12 in.) long by 22.86 cm (9 in.) wide. Due to the hose bend radii, the hole must be
positioned towards the side of the rack without the manifold (the left side of the rack when looking at the
rear of the rack). The left edge of the hole must be at least 11.43 cm (4.5 in.) from the side and 3.81 cm
(1.5 in.) from the back edge of the rack (not including doors). Hole placement on the tile depends on the
location of the rack, tile size, and tile load limitations.

Heat exchanger performance

A heat removal of 100% indicates that an amount of heat that is equivalent to that generated by the
devices has been removed by the heat exchanger and the average air temperature leaving the heat
exchanger is identical to that entering the rack (27°C (80.6°F) in this example). Heat removal in excess of
100% indicates that the heat exchanger not only removed all of the heat that was generated by the
devices, but further cooled the air so that the average air temperature that is leaving the rack is actually
lower than air temperature that is entering the rack.

To help maintain optimum performance of the rear door heat exchanger and provide proper cooling for all
rack components, you must take the following precautions:

• Install ller panels over all unoccupied bays.

• Route signal cables at the rear of the rack so that they enter or exit the cabinet through the top and
bottom air baffles.

• Bundle signal cables together in a rectangle so that the upper and lower air-baffle sliders are closed as
far as possible. Do not bundle signal cables together in a circular formation.

Water specications for the secondary cooling loop

Important:

The water that is being supplied to the heat exchanger must meet the requirements that are described in
this section.

Do not use glycol solutions because they can adversely affect the cooling performance of the heat
exchanger.

Cooling loop requirements

A secondary cooling loop, separate from the main site cooling loop, is required for the rear door heat
exchanger. Cooling distribution units are available from suppliers such as Coolcentric.

The secondary cooling loop must meet the requirements that are outlined in the water chemistry

specication. For more information about water chemistry requirements, see Water cooling system
specication and requirements.

Water-supply requirements for secondary loops

Learn about the specic characteristics of the system that supplies the chilled conditioned water to the
heat exchanger.

Temperature:

The heat exchanger and its supply hose and return hoses are not insulated. Avoid any condition that
might cause condensation. The temperature of the water inside the supply hose, return hose, and
heat exchanger must be kept above the dew point of the location where the heat exchanger is being
used.

Attention:

chilled water can be as cold as 4°C - 6°C (39°F - 43°F).

Important:

Typical primary chilled water is too cold for use in this application because building

Site and hardware planning

61

The system that supplies the cooling water must be able to measure the room dew point and
automatically adjust the water temperature accordingly. Otherwise, the water temperature must be
above the maximum dew point for that data center installation. For example, the following minimum
water temperature must be maintained:

• 18°C plus or minus 1°C (64.4°F plus or minus 1.8°F). This specication is applicable within an
ASHRAE Class 1 Environmental Specication that requires a maximum dew point of 17°C (62.6°F).

• 22°C plus or minus 1°C (71.6°F plus or minus 1.8°F). This specication is applicable within an
ASHRAE Class 2 Environmental Specication that requires a maximum dew point of 21°C (69.8°F).

See the ASHRAE document Thermal Guidelines for Data Processing Environments.

Pressure:

The water pressure in the secondary loop must be less than 690 kPa (100 psi). Normal operating
pressure at the heat exchanger must be 414 kPa (60 psi) or less.

Flow rate:

The flow rate of the water in the system must be in the range of 23 - 57 liters (6 - 15 gallons) per
minute.

Pressure drop versus flow rate for heat exchangers (including quick-connect couplings) is dened as
approximately 103 kPa (15 psi) at 57 liters (15 gallons) per minute.

Water volume limits:

The heat exchanger holds approximately 9 liters (2.4 gallons). Fifteen meters (50 ft) of 19 mm (0.75
in.) supply and return hoses hold approximately 9.4 liters (2.5 gallons). To minimize exposure to
flooding in the case of leaks, the entire product cooling system (heat exchanger, supply hose, and
return hose), excluding any reservoir tank, must have a maximum 18.4 liters (4.8 gallons) of water.
This is a cautionary statement, not a functional requirement. Also, consider using leak detection
methods on the secondary loop that supplies water to the heat exchanger.

Air exposure:

The secondary cooling loop is a closed loop, with no continuous exposure to room air. After you ll the
loop, remove all air from the loop. An air bleed valve is provided at the top of a heat exchanger
manifold for purging all air from the system.

Water delivery specications for secondary loops

Learn about the various hardware components that make up the delivery system secondary loop that
provides the chilled, conditioned water to the heat exchanger. The delivery system includes pipes, hoses,
and the required connection hardware to connect the hoses to the heat exchanger. Hose management
can be used in raised-floor and non-raised-floor environments.

The heat exchanger can remove 100% or more of the heat load from an individual rack when it is running
under optimum conditions.

The primary cooling loop is considered to be the building chilled-water supply or a modular chiller unit.
The primary loop must not be used as a direct source of coolant for the heat exchanger.

Procurement and installation of the components that are needed to create the secondary cooling loop
system are required for this design and are your responsibility. The main purpose is to provide examples
of typical methods of secondary loop setup and operating characteristics that are needed to provide an
adequate and safe supply of water to the heat exchanger.

Attention:

The overpressure safety device must meet the following requirements:

• Comply with ISO 4126-1.

• Be installed so that it is easily accessed for inspection, maintenance, and repair.

• Be connected as close as possible to the device that it is intended to protect.

62 Power Systems: Site and hardware planning

• Be adjustable only with the use of a tool.

• Have a discharge opening that is directed so that discharged water or fluid does not create a
hazard or be directed toward any person.

• Be of adequate discharge capacity to ensure that the maximum working pressure is not
exceeded.

• Be installed without a shutoff valve between the overpressure safety device and the protected
device.

Read the following guidelines before you design the installation:

• A method for monitoring and setting the total flow rate that is delivered to all of the heat exchangers is
required. This can be a discrete flowmeter that is built into the flow loop or a flowmeter within the
secondary loop of the coolant distribution unit (CDU).

• After you set the total flow rate for all of the heat exchangers by using a flowmeter, it is important to
design the plumbing so that it provides the flow rate that you want for each heat exchanger and
provides a way to verify the flow rate. Other methods, such as inline or external flowmeters, can provide
a more accurate method for setting the flow rate through the individual shutoff valves.

Manifolds and piping:

Manifolds that accept large-diameter feed pipes from a pump unit are the preferred method for
splitting the flow of water to smaller-diameter pipes or hoses that are routed to individual heat
exchangers. Manifolds must be constructed of materials that are compatible with the pump unit and
related piping. The manifolds must provide enough connection points to allow a matching number of
supply and return lines to be attached, and the manifolds must match the capacity rating of the
pumps and the loop heat exchanger (between the secondary cooling loop and the building chilled­water source). Anchor or restrain all manifolds to provide the required support to avoid movement
when quick-connect couplings are connected to the manifolds.

Example of manifold supply pipe sizes:

• Use a 50.8 mm (2 in.) or larger supply pipe to provide the correct flow to three 19 mm (0.75 in.)
supply hoses, with a 100 kW coolant distribution unit (CDU).

• Use a 63.5 mm (2.50 in.) or larger supply pipe to provide the correct flow to four 19 mm (0.75 in.)
supply hoses, with a 120 kW CDU.

• Use an 88.9 mm (3.50 in.) or larger supply pipe to provide the correct flow to nine 19 mm (0.75 in.)
supply hoses, with a 300 kW CDU.

To stop the flow of water in individual legs of multiple circuit loops, install shutoff valves for each
supply and return line. This provides a way to service or replace an individual heat exchanger without
affecting the operation of other heat exchangers in the loop.

To ensure that water specications are being met and that the optimum heat removal is taking place,
use temperature and flow metering (monitoring) in secondary loops.

Anchor or restrain all manifolds and pipes to provide the required support and to avoid movement
when quick-connect couplings are being attached to the manifolds.

Flexible hoses and connections to manifolds and heat exchangers:

Pipe and hose congurations can vary. You can determine the best conguration for your installation
by analyzing the needs of your facilities, or a site preparation representative can provide this analysis.

Flexible hoses for the cold-water supply and warm water return are provided with the delivery of the
rear door heat exchanger (allowing needed movement for opening and closing the rack rear door). The
customer needs to supply a 2.54 cm (1 in.) female national pipe thread (NPT) tting for each supply
and return hose connection to the facility. The IBM supplied hoses contain the quick connect ttings
to mate to the ttings on the rear door heat exchanger.

Use solid piping or tubing that has a minimum inner diameter of 19 mm (0.75 in.) and the fewest
possible joints between a manifold and a heat exchanger in each secondary loop.

Rack installation specications for racks that are not purchased from IBM

Learn about the requirements and specications for installing IBM systems into racks that were not
purchased from IBM.

Learn about the requirements and specications for 19-inch racks. These requirements and
specications are provided as an aid to help you understand the requirements to install IBM systems into
racks. It is your responsibility, working with your rack manufacturer, to ensure that the rack that is chosen
meets the requirements and specications that are listed here. Mechanical drawings of the rack, if
available from the manufacturer, are recommended for comparison against the requirements and

specications.

70

Power Systems: Site and hardware planning

IBM maintenance services and installation planning services do not cover verication of non-IBM racks
for compliance to Power Systems rack specications. IBM offers racks for IBM products that are tested
and veried by IBM development labs to comply with applicable safety and regulatory requirements.
These racks are also tested and veried to t and function with IBM products. The customer is
responsible for verifying with the rack manufacturer that any non-IBM racks comply with IBM

specications.

Note: IBM 7014-T00, 7014-T42, 7014-B42, 7953-94X, 7965-94Y, and 7965-S42 racks meet all the
requirements and specications.

Rack specications

The general rack specications include the following specications:

• The rack or cabinet must meet the EIA Standard EIA-310-D for 19-inch racks published August 24,

1992. The EIA-310-D standard species internal dimensions, for example, the width of the rack
opening (width of the chassis), the width of the module mounting flanges, and the mounting hole
spacing.

• The front rack opening must be a minimum of 450 mm (17.72 in.) wide, and the rail-mounting holes
must be 465 mm plus or minus 1.6 mm (18.3 in. plus or minus 0.06 in.) apart on center (horizontal
width between vertical columns of holes on the two front-mounting flanges and on the two rear­mounting flanges).

* The range for models 9008-22L, 9009-22A, 9009-41A, 9009-42A, 9223-22H, and 9223-42H is

609.6 mm - 812.8 mm (24.0 in. - 32.0 in.).

Figure 23. Rack specications (top-down view)

• The vertical distance between mounting holes must consist of sets of three holes spaced (from bottom
to top) 15.9 mm (0.625 in.), 15.9 mm (0.625 in.), and 12.7 mm (0.5 in.) on center (making each three­hole set of vertical hole spacing 44.45 mm (1.75 in.) apart on center).

Site and hardware planning

71

• The following rack hole sizes are supported for racks where IBM hardware is mounted:

– 7.1 mm (0.28 in.) plus or minus 0.1 mm (round)
– 9.5 mm (0.37 in.) plus or minus 0.1 mm (square)

The rack or cabinet must be capable of supporting an average load of 20 kg (44 lb) of product weight
per EIA unit.

For example, a four EIA drawer has a maximum drawer weight of 80 kg (176 lb).

• The system requires space at the rear of the rack for system brackets and cables.

For model 9008-22L, 9009-22A, 9009-41A, 9009-42A, 9223-22H, and 9223-42H, you must have a
minimum rear clearance of 240 mm (9.45 in.).

• Only ac power drawers are supported in the rack or cabinet. It is strongly recommended to use a power
distribution unit that meets the same specications as IBM power distribution units to supply rack
power (for example, feature code 7188). Rack or cabinet power distribution devices must meet the
drawer voltage, amperage, and power requirements, as well as that of any additional products that are
connected to the same power distribution device.

The rack or cabinet power receptacle (power distribution unit, uninterruptible power supply, or multi­outlet strip) must have a compatible plug type for your drawer or device.

• The rack or cabinet must be compatible with the drawer-mounting rails. The rail-mounting pins and
screws must t securely and snugly into the rack or cabinet rail-mounting holes. The mounting rails and
mounting hardware that are provided with IBM products are designed and tested to safely support the
product during operation and service activities, and to safely support the weight of your drawer or
device. The rails must facilitate service access by allowing the drawer to be safely extended, if
necessary, forward, backward, or both. Some rails, with IBM features for non-IBM racks, provide
drawer-specic anti-tip brackets, rear lock-down brackets, and cable management guides that require
clearance on the rear side of the rails.

Note: If the rack or cabinet has square holes on the mounting flanges, an adapter might be required.

• The rack or cabinet must have stabilization feet or brackets installed in the front of the rack, or have
another means of preventing the rack/cabinet from tipping while the drawer or device is pulled into its
extreme front service positions.

Note: Examples of some acceptable alternatives: The rack or cabinet might be securely bolted to the
floor, ceiling or walls, or to adjacent racks or cabinets in a long and heavy row of racks or cabinets.

• If present, front and rear doors must be able to open far enough to provide unrestrained access for
service or be easily removable. If doors must be removed for service, it is the responsibility of the
customer to remove them before service.

• Front and rear doors must not violate the previously dened front and rear rack space that is required
for the system.

• The rack or cabinet must provide adequate front-to-back ventilation.

Note: Rack doors must be fully perforated to provide proper front-to-back airflow for mounted
Information Technology (IT) equipment. The total door area must result in a minimum of 45% opening
area. Rear doors must not create back pressure that can interfere with the server fan operation.

General safety requirements for IBM products installed in a non-IBM rack or cabinet

The general safety requirements for IBM products that are installed in non-IBM racks are:

Site and hardware planning

75

• Any product or component that plugs into either an IBM power distribution unit or mains power (by
using a power cord), or uses any voltage over 42 V ac or 60 V dc (considered to be hazardous voltage)
must be Safety Certied by a Nationally Recognized Test Laboratory (NRTL) for the country in which it is
installed.

Some of the items that require safety certication might include the rack or cabinet (if it contains
electrical components integral to the rack or cabinet), fan trays, power distribution unit, uninterruptible
power supplies, multi-outlet strips, or any other products that are installed in the rack or cabinet that
connect to hazardous voltage.

Examples of OSHA-approved NRTLs for the US:

– UL
– ETL
– CSA (with CSA NRTL or CSA US mark)

Examples of approved NRTLs for Canada:

– UL (Ulc mark)
– ETL (ETLc mark)
– CSA

The European Union requires a CE mark and a Manufacturer's Declaration of Conformity (DOC).

Certied products must have the NRTL logos or marks somewhere on the product or product label.
However, proof of certication must be made available to IBM upon request. Proof consists of such
items as copies of the NRTL license or certicate, a CB Certicate, a Letter of Authorization to apply the
NRTL mark, the rst few pages of the NRTL certication report, Listing in an NRTL publication, or a copy
of the UL Yellow Card. Proof should contain the manufacturers name, product type, and model,
standard to which it was certied, the NRTL name or logo, the NRTL le number or license number, and
a list of any Conditions of Acceptance or Deviations. A Manufacturer's Declaration is not proof of
certication by an NRTL.

• The rack or cabinet must meet all electrical and mechanical safety legal requirements for the country in
which it is installed. The rack or cabinet must be free of exposed hazards (such as voltages over 60 V dc
or 42 V ac, energy over 240 VA, sharp edges, mechanical pinch points, or hot surfaces).

• There must be an accessible and unambiguous disconnect device for each product in the rack, including
any power distribution unit.

A disconnect device might consist of either the plug on the power cord (if the power cord is no longer
than 1.8 m (6 ft)), the appliance inlet receptacle (if the power cord is of a detachable type), or a power
on/off switch, or an Emergency Power Off switch on the rack, provided all power is removed from the
rack or product by the disconnect device.

If the rack or cabinet has electrical components (such as fan trays or lights), the rack must have an
accessible and unambiguous disconnect device.

• The rack or cabinet, power distribution unit and multi-outlet strips, and products that are installed in
the rack or cabinet must all be properly grounded to the customer facility ground.

There must be no more than 0.1 Ohms between the ground pin of the power distribution unit or rack
plug and any touchable metal or conductive surface on the rack and on the products that are installed in
the rack. Grounding method must comply with applicable country's electric code (such as NEC or CEC).
Ground continuity can be veried by your IBM service personnel, after the installation is completed, and
must be veried before the rst service activity.

• The voltage rating of the power distribution unit and multi-outlet strips must be compatible with the
products plugged into them.

The power distribution unit or multi-outlet strips current and power ratings are rated at 80% of the
building supply circuit (as required by the National Electrical Code and the Canadian Electrical Code).
The total load that is connected to the power distribution unit must be less than the rating of the power
distribution unit. For example, a power distribution unit with a 30 A connection is rated for a total load

76

Power Systems: Site and hardware planning

of 24 A (30 A x 80 %). Therefore, the sum of all equipment that is connected to the power distribution
unit in this example must be lower than the 24 A rating.

If an uninterruptible power supply is installed, it must meet all the electrical safety requirements as
described for a power distribution unit (including certication by an NRTL).

• The rack or cabinet, power distribution unit, uninterruptible power supply, multi-outlet strips, and all
products in the rack or cabinet must be installed according to the manufacturer's instructions, and in
accordance with all national, state or province, and local codes and laws.

The rack or cabinet, power distribution unit, uninterruptible power supply, multi-outlet strips, and all
products in the rack or cabinet must be used as intended by the manufacturer (per manufacturer's
product documentation and marketing literature).

• All documentation for use and installation of the rack or cabinet, power distribution unit, uninterruptible
power supply, and all products in the rack or cabinet, including safety information, must be available
onsite.

• If there is more than one source of power in the rack cabinet, there must be clearly visible safety labels
for Multiple Power Source (in the languages that are required for the country in which the product
is installed).

• If the rack or cabinet or any products that are installed in the cabinet had safety or weight labels that
are applied by the manufacturer, they must be intact and translated into the languages that are required
for the country in which the product is installed.

• If the rack or cabinet has doors, the rack becomes a re enclosure by denition and must meet the
applicable flammability ratings (V-0 or better). Totally metal enclosures at least 1 mm (0.04 in.) thick
are considered to comply.

Nonenclosure (decorative) materials must have a flammability rating of V-1 or better. If glass is used
(such as in rack doors), it must be safety glass. If wood shelves are used in the rack/cabinet, they must
be treated with a UL Listed flame-retardant coating.

• The rack or cabinet conguration must comply with all IBM requirements for "safe to service" (contact
your IBM Installation Planning Representative for assistance in determining if the environment is safe).

There must be no unique maintenance procedures or tools that are required for service.

Elevated service installations, where the products to be serviced are installed between 1.5 m and 3.7 m
(5 ft and 12 ft) above the floor, require the availability of an OSHA- and CSA-approved nonconductive
step ladder or ladders. If a ladder or ladders are required for service, the customer must supply the
OSHA- and CSA- approved nonconductive step ladder (unless other arrangements are made with the
local IBM Service Branch Ofce). Some products can have rack installation limitations. Refer to the
specic server or product specications for any restrictions. Products that are installed over 2.9 m (9 ft)
above the floor require a Special Bid to be completed before they can be serviced by IBM service
personnel.

For products not intended for rack-mounting to be serviced by IBM, the products and parts that are
replaced as part of that service must not weigh over 11.4 kg (25 lb) Contact your Installation Planning
Representative if in doubt.

There must not be any special education or training that is required for safe servicing of any of the
products that are installed in the racks. Contact your Installation Planning Representative if you are in
doubt.

77

Rack specications provide detailed information for your rack, including dimensions, electrical, power,
temperature, environment, and service clearances.

Planning for power

Planning the power for your system requires knowledge of your server's power requirements, the power
requirements of compatible hardware, and the uninterruptible power supply needs for your server. Use
this information to build a complete power plan.

Before you begin your planning tasks, be sure you that complete the items in the following checklist:

• Know your server power requirements.

• Know your compatible hardware requirements.

• Know your uninterruptible power supply needs.

Review power considerations

Complete the following checklist:

• Consult a qualied electrician about power needs.

• Determine an uninterruptible power supply vendor.

• Complete your server information form or forms.

Determining your power requirements

Use these guidelines to ensure that your server has the proper power to operate.

Your server can have power requirements different from a PC (such as different voltage and different
plugs). IBM supplies power cords with an attached plug that corresponds to the power outlet most
commonly used in the country or region to which the product is being shipped. You are responsible for
supplying the proper power outlets.

• Plan for system electrical service. For information on power requirements for a specic model, refer to
the electrical section in the server specications for that particular server. For information on power
requirements for expansion units or peripherals, select the appropriate device from the list of
compatible hardware specications. For equipment not listed, check your equipment documentation
(owner's manuals) for specications.

• Determine your server's plug and receptacle types by model so that you can install the proper outlets.

Tip: Print a copy of your plug and receptacle table and give it to your electrician. The table contains
information that is needed for installing outlets.

• Write down power information in your Server Information Form 3A. Include the following information:

– Plug type
– Input voltage
– Power cord length (optional)

• Plan for power outages. Consider purchasing an uninterruptible power supply to protect your system
against power fluctuations and outages. If your company owns an uninterruptible power supply, involve
your uninterruptible power supply vendor with any type of uninterruptible power supply modication.

• Plan an emergency power-off switch. As a safety precaution, you must provide some method for
disconnecting power to all equipment in your server area. Put emergency power-off switches in
locations readily accessible to your systems operator and at designated exits from the room.

• Ground your system. Electrical grounding is important both for safety and correct operation. Your
electrician must follow your national and local electrical codes when installing the electrical wiring,
outlets, and power panels. These codes take precedence over any other recommendations.

78

Power Systems: Site and hardware planning

• Contact an electrician. Contact a qualied electrician to take care of your server power requirements
and install needed power outlets. Give the electrician a copy of your power information. You can print
the recommended power distribution wiring diagram as a reference for your electrician.
