As computer systems have evolved in size and complexity, managing them has
become a critical concern. By centralizing your equipment in a HP 10000 Series rack,
the efficiency and accessibility of your system can be increased dramatically.
The 10000 Series racks are designed to house rack-mountable products on industrystandard 19-inch (48.26-cm) wide rails. Using rack-mountable products allows you to
decrease the footprint required to house your existing hardware while still providing
expansion capability.
Racks and rack-mountable components are typically described using
U measurements. For example, one U is 44.45 mm (1.75 inches) high.
HP 10842 Rack
The HP 10842 rack is a 800 x 1000 mm 42U rack that arrives in a server/storage
configuration with internal mounting rails that are front justified, allowing the
customer room in the rear of the rack for cable routing.
1
Overview
The 10842 rack offers the following features:
• Perforated front door, solid side panels (optional), and split rear perforated doors
• Cable access panel that allows routing and cable management
• Perforated rack top with egress slot
HP 10842 Rack Reference Guide 1-1

Delivery Considerations
The following list is only a sampling of the many delivery considerations available.
For more information, visit the Best Practices Web page at
When preparing to receive palletized racks, consider the following:
• The dock door at the receiving site has to accommodate the height and width of
palletized racks.
IMPORTANT: The 42U-palletized rack is approximately 216.87 cm (85.38 inches) high
and does not fit through a standard-height door.
• Do not lay a rack on its side, because the sheet metal can become distorted.
• Transport a rack as far into the building as possible while it is still on the pallet.
Ideally, move the palletized rack to its final destination before removing the rack
from the pallet, or removing any of the packaging.

2-2 HP 10842 Rack Reference Guide
Page 19
Rules for Component Placement
The following rules apply to the physical placement of components in the rack.
• Weight—Sort all components by weight, placing the heaviest components at the
bottom of the rack.
• Balance—Be sure to balance the weight load between racks, placing the heaviest
components at the bottom. For example, if you have several UPS units and
several servers, do not put all of the UPS units into one rack—distribute them
evenly in the bottom positions of each rack.
• Server Console Switch—Position the switch box on the side of the rack above
the keyboard, or mount it behind the keyboard.
• CRT Monitor—Position the monitor topmost within the rack.
• Rack Mountable Flat Panel Monitor—Select a position to accommodate the
desired viewing height (a minimum of 4Us above the keyboard tray).
Additional Considerations
Configuration Factors
The following are additional items to consider, based on your specific rack
configuration.
• Power—If a UPS is installed, do not exceed its output rating. Be sure to review
the installation instructions provided with each component for important cautions
and warnings.
• PDUs—Install PDUs before installing other components.
• Height—The height of the rack and of rack-mountable components is measured
in U increments. When you are configuring your rack installation, remember that
the total U measurement of the components you want to install cannot exceed the
stated U height of the rack.
• Keyboard—The rack keyboard requires prior installation of a 1U Keyboard
Drawer Rack Option Kit.
HP 10842 Rack Reference Guide 2-3
Page 20
Configuration Factors
• Monitor—The monitor requires installation of a Monitor/Utility Shelf Rack
Option Kit unless you are using a rack-mountable flat panel monitor.
• Server Console Switch—If a switch box is configured, use the CPU-to-Switch
cable included with the server. The standard distance between the switch box and
the keyboard, monitor, and/or mouse can vary by 3-, 7-, 12-, 20- and 40-foot
(91.44-, 213.36-, 365.76-, 609.6-, and 1219.2-cm) lengths. Optional Plenumrated KVM cables are available in 20- and 40-foot (609.6- and 1219.2-cm)
lengths.
NOTE: National Electrical Regulations governing the installation of building wiring require
that an appropriate cable, meeting fire-safety standards, be used any time cabling is
routed:
• Through an overhead drop-ceiling
• Under a computer room’s raised flooring
• From room to room
• From floor to floor
Be sure that the cable jacket or sleeving is made of material that does not burn easily and
does not exude toxic fumes when exposed to heat. Be sure that the cable you have
selected is appropriate for your installation site. If you require U.S. plenum-rated (CL2P)
cable, please contact your local HP authorized reseller to obtain the following options:
• 149363-B21—20-foot (609.6-cm) plenum cable
• 149364-B21—40-foot (1219.2-cm) plenum cable
• Rack Option Baying Kit—The number of baying kits needed to join a series of
racks is one less than the number of racks in the suite.
• Rack Option Offset Baying Kit—This kit joins multiple racks of different
series with the same height but different depths.
• Sidewall Panels—Only one set of sidewall panels is required for each row of
bayed racks.
• Stabilizing Feet—A stand-alone rack requires stabilizing feet.
2-4 HP 10842 Rack Reference Guide
Page 21
Optimum Environment
Specific requirements for space, power, temperature, and airflow must be met to
provide optimum performance with minimum maintenance for your rack
environment.
Space Requirements
When deciding where to place your rack:
• At least 122 cm (48 inches) of clearance is needed all the way around the pallet
and above the rack to allow the removal of packing materials.
• At least 86 cm (34 inches) of clearance is needed in front of the rack to allow the
door to open all the way.
• At least 75 cm (30 inches) of clearance is needed in the rear of the rack to
provide access to components.
• At least 38 cm (15 inches) of clearance is needed around a power supply to
facilitate servicing.
Configuration Factors
Power Requirements
WARNING: To reduce the risk of personal injury, fire, or damage to the
equipment, do not overload the AC supply branch circuit that provides power
to the rack. Consult the electrical authority having jurisdiction over your
facility wiring and installation requirements.
When planning for power distribution requirements for your rack configuration:
• The power load must be balanced between available AC supply branch circuits.
• The overall system AC current load must not exceed 80 percent of the branch
circuit AC current rating.
• If a UPS is used, the load should not exceed 80 percent of the marked electrical
current rating of the UPS.
HP 10842 Rack Reference Guide 2-5
Page 22
Configuration Factors
CAUTION: To reduce the risk of damage to the equipment, verify that all AC voltage
selector switches are set correctly to match your local AC line voltage
(115V or 230V). If the AC voltage selector switch is not properly set, your
components will be damaged when power is applied.
The installation of this equipment shall be in accordance with local/regional electrical
regulations governing the installation of Information Technology Equipment by
licensed electricians. This equipment is designed to operate in installations covered
by the National Electric Code (ANSI/NFPA-70, 1993) and the code for Protection of
Electronic Computer/Data Processing Equipment (NFPA-75, 1992).
For electrical power ratings on options, refer to the product’s rating label or user
documentation supplied with that option.
Grounding Requirements
For proper operation and safety, all powered rack-mountable components are
required to be properly grounded in accordance with NFPA 70-1993, Article 250. All
power distribution devices, branch wiring, and receptacles must be listed as
grounding-type devices.
When using power strips for electrical distribution, make sure that ground integrity is
maintained for each connection made. Plug each component into a reliably grounded
outlet.
WARNING: To reduce the risk of electric shock or damage to your equipment,
do not disable the power cord grounding feature. This equipment is designed
to be connected to a grounded (earthed) power outlet that is easily accessible
and located as close as possible to the equipment. The grounding plug is an
important safety feature.
2-6 HP 10842 Rack Reference Guide
Page 23
Temperature Requirements
For safe and reliable operation of equipment, locate the system in a well-ventilated,
climate-controlled environment.
Configuration Factors
The HP Maximum Recommended Ambient Operating Temperature (T
) for most
MRA
server products is 95°F (35°C). Therefore, the temperature in the room where the
rack is located should not exceed 95°F (35°C).
The operating temperature inside the rack is always higher than the room
temperature, and is dependent on the configuration of equipment in your rack. Check
the T
for each piece of equipment before installation.
MRA
The maximum internal rack temperature for your configuration should not exceed the
values in the following table.
Table 2-1: Rack Internal Temperature Maximums
Equipment Included Maximum Internal Rack Temperature
HP rack-mountable servers 95°F/35°C
HP rack-mountable options 104°F/40°C
HP PDUs 122°F/50°C
Other manufacturers’ options See other manufacturers’ specifications
CAUTION: To reduce the risk of damage to the equipment when installing
third-party options:
• Make sure that the option equipment does not impede airflow to the
rack-mountable products already installed in the rack, nor increase the internal
rack temperature beyond the maximum rating specified by HP.
• Make sure that the manufacturer’s Maximum Recommended Ambient Operating
Temperature for the option equipment is not exceeded when the option
equipment is installed in a HP rack.
HP 10842 Rack Reference Guide 2-7
Page 24
Configuration Factors
Airflow Requirements
HP rack-mountable products typically draw in cool air through the front and exhaust
warm air out through the rear of the rack. The front door of the rack, therefore, must
be adequately ventilated to allow ambient room air to enter the rack, and the rear
door must be adequately ventilated to allow the warm air to escape the rack. Do not
block the ventilation apertures.
Fan Kits
If additional cooling is required, fan kits can be used to draw heated air from the rear
of the rack, out through the top.
Blanking Panels
If the front of the rack is not completely filled with components, the remaining gaps
between the components can cause changes in the airflow that adversely affect
cooling within the rack. Cover these gaps with blanking panels.

Stabilizing the Rack
WARNING: The rack allows you to stack computer components on a vertical
rather than a horizontal plane. To reduce the risk of personal injury or damage
to the equipment, you must follow these instructions carefully and heed all
cautions and warnings throughout the installation instructions.
Standalone Racks
If you are installing a single (standalone) rack, make sure that the rack is level and
that the stabilizing feet have been attached, before installing the components. If an
unstable rack is loaded with components, it can become unbalanced and may tip over.
Extending the Leveling Feet
CAUTION: To reduce the risk damage to the casters, make sure that the full weight
of the rack rests on the leveling feet, and not on the casters. The casters are
designed only as an aid in moving the rack into position. They are not designed to
support the weight of the rack and may become damaged if relied on to support the
rack.
The leveling feet, located beside each caster on the rack, unscrew and extend to the
floor, resting in leveling feet bases provided with your rack. These feet support the
rack and help compensate for uneven surfaces.
After positioning the rack in its final location, use an adjustable wrench to extend the
leveling feet to the base until the weight of the rack is fully on the feet and feet bases,
not the casters. This stabilizes the rack for installation of your components.

Attaching the Stabilizing Feet
WARNING: To reduce the risk of personal injury, you must attach the
stabilizing feet to all standalone (non-bayed) racks.
The Stabilizer Rack Option Kit contains three full-size stabilizing feet that are used
for standalone racks. Attach one stabilizing foot to the front and one to each side of
the rack. Stabilizing feet are not required on the back of a standalone rack.
Preparing the Rack

Preparing the Rack
Multiple Racks
To increase space and stability, 10842 racks can be bayed together by installing the
Rack Option Baying Kit or the Rack Option Offset Baying Kit, depending on the
series, height, and depth.
• Rack Option Baying Kit—Joins multiple racks of the same series, height, and
depth
• Rack Option Offset Baying Kit—Joins multiple racks of different series with
the same height but different depths
Observe the following tips when using multiple-rack configurations:
• Stabilizing feet are optional with bayed racks.
• The number of baying kits needed is one less than the total number of racks.
• Position and install either baying option kit before populating the racks with
components.
• Racks from different series can be bayed together as long as they are the same
height.
Server/Storage vs. Switching Configurations
The 10842 rack offers interchangeable front and rear doors that allow the rack to be
used in server/storage or switching applications. The 42U rack arrives in a
server/storage configuration with internal mounting rails that are front-justified,
providing the customer greater room in the rear of the rack for cable routing.

Installing Components in the Rack
General Guidelines
WARNING: To reduce the risk of personal injury, always be sure that the rack
is adequately stabilized before extending a component outside the rack. A rack
may become unstable if more than one component is extended for any reason.
Extend only one component at a time.
WARNING: To reduce the risk of personal injury or damage to the equipment,
always load the heaviest item first from the bottom of the rack up. This makes
the rack bottom-heavy and helps prevent the rack from becoming unstable.
Refer to Chapter 2, “Configuration Factors,” for more information about the
placement of rack-mountable components.
WARNING: To reduce the risk of personal injury or damage to the equipment,
be sure that:
• The leveling jacks are extended to the floor.
• The full weight of the rack rests on the leveling jacks.
• The stabilizing feet are attached to the rack if it is a single-rack installation.
• The racks are coupled together in multiple-rack installations.
• Only one component is extended at a time. A rack may become unstable if
more than one component is extended for any reason.
CAUTION: To reduce the risk of damage to the equipment when installing
third-party options:
• Be sure the option equipment installed does not impede airflow to the
rack-mountable ProLiant servers or increase the internal rack temperature
beyond the maximum rating specified by HP.
• Be sure that the option equipment installed does not exceed the manufacturer’s
Maximum Recommended Ambient Operating Temperature.
4-2 HP 10842 Rack Reference Guide
Page 37
Observe the general guidelines when installing your components:
• Refer to the user documentation that was shipped with the component for
detailed instructions on installing a specific component or third-party hardware.
• Refer to Appendix A, “Electrostatic Discharge,” before installing components
into the rack.
• Use the configuration prepared with the Rack Builder Online software as a
guideline for installing the components.
• Install the heavier components first from the bottom of the rack up.
• Be sure to balance the weight load between bayed racks. For example, if you
have several UPS units and several servers, do not install all of the UPS units into
one rack. Instead distribute them evenly in the bottom positions of each rack.
• Allow a minimum clearance of 76 cm (30 inches) between the wall and the rear
of the rack to provide adequate access for installation and service.
Component Installation Overview
NOTE: The stabilizer feet should be installed before any component installation.
IMPORTANT: The following installation instructions are for standard installations. For specific
installation instructions, refer to the documentation included with your component.
Installing Components in the Rack
The following steps outline the sequence for installing rack-mountable components
in a rack. You should install zero U devices first, such as PDUs, switch boxes, and
so on.
1. Use the template to measure and mark the rack for correct placement of the
installation hardware.
2. Install the cage nuts into the rack.
3. Prepare and install the adjustable fixed rails, sliding rails, or both.

Installing Components in the Rack
WARNING: To reduce the risk of electrical 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.
• When using an optional power distribution device, make sure that the
ground integrity is maintained for each connection by plugging each
component into a reliable grounded outlet.
CAUTION: To reduce the risk of damage to the equipment, verify that all AC voltage
selector switches are set to match your local AC line voltage (115V or 230V). If the
AC voltage selector switches are not properly set, your components will be damaged
when power is supplied.
5. After all cables and power cords have been routed to their power destinations,
connect the power cords to a main power switch such as a properly rated Power
Distribution Unit (PDU).
NOTE: If you are not using a PDU, route the power cord directly to a properly rated and
grounded AC wall or floor outlet.

Electrostatic Discharge
To prevent damaging the system, be aware of the precautions you need to follow
when setting up the system or handling parts. A discharge of static electricity from a
finger or other conductor may damage system boards or other static-sensitive
devices. This type of damage may reduce the life expectancy of the device.
To prevent electrostatic damage, observe the following precautions:
• Avoid hand contact by transporting and storing products in static-safe containers.
• Keep electrostatic-sensitive parts in their containers until they arrive at static-free
workstations.
• Place parts on a grounded surface before removing them from their containers.
• Avoid touching pins, leads, or circuitry.
• Always be properly grounded when touching a static-sensitive component or
assembly.
HP 10842 Rack Reference Guide A-1
Page 61
Electrostatic Discharge
Grounding Methods
There are several methods for grounding. Use one or more of the following methods
when handling or installing electrostatic-sensitive parts:
• Use a wrist strap connected by a ground cord to a grounded workstation or
computer chassis. Wrist straps are flexible straps with a minimum of 1 megohm
± 10 percent resistance in the ground cords. To provide proper ground, wear the
strap snug against the skin.
• Use heel straps, toe straps, or boot straps at standing workstations. Wear the
straps on both feet when standing on conductive floors or dissipating floor mats.
• Use conductive field service tools.
• Use a portable field service kit with a folding static-dissipating work mat.
If you do not have any of the suggested equipment for proper grounding, have HP
authorized reseller install the part
NOTE: For more information on static electricity, or assistance with product installation,
contact your HP authorized reseller.

Transportation Instructions
NOTE: The following section is only a sampling of the many delivery considerations available.
For more information, visit the Best Practices Web page at www.hp.com.
Transportation Methods
Depending on your circumstances and time schedule, there are three transportation
methods for transporting your rack: air, land, and sea.
Air Transport
All racks can be air freighted upright (on a pallet or shock pallet) or horizontally
(in a crate). However, since the 10842 rack has a packaged height of 217 centimeters
(85.4 inches) and the maximum height for air cargo is 218.4 centimeters (86 inches),
only the largest cargo planes can accommodate it upright. If your destination does not
accommodate large cargo planes, the 10842 rack must be air freighted horizontally in
a crate.
B
A passenger plane with cargo space has a height limitation of 160 centimeters
(63 inches). Because a palletized 10622 rack is below this limit, it can readily be
delivered by air. It must be shipped upright on a pallet, and double-stacking is not
allowed.
CAUTION: If your rack is an integrated model, it MUST be transported upright. If
this is not possible, remove all components from the rack and prepare them for
delivery, or choose an alternative transportation method.
HP 10842 Series Reference Guide B-1
Page 63
Transportation Instructions
Because of the dimensions and the weight of the racks, check with carriers for their
limitations before dispatching.
Land Transport
All racks can be shipped by common carriers. Carriers providing air ride capabilities
are preferred. Ship racks upright on their pallets. Do not lay the racks horizontally or
double-stack them. Because of the dimensions and the weight of the racks, please
check with carriers for their restrictions before dispatching.
Sea Transport
All racks can be transported by sea, but it takes four to six weeks for the shipment to
arrive. Ship racks upright on their pallets. Do not lay the racks horizontally or
double-stack them.
Delivery Services
HP provides two methods of delivery for customers in North America: Inside Rack
Delivery Service and Expedited Rack Delivery Service. If you want both Inside Rack
Delivery and Expedited Rack Delivery, you must specify both part numbers on your
purchase order.
Inside Rack Delivery Service
Inside Rack Delivery Service (Part No. 184649-001) is available for receiving sites
that do not have the proper facilities for the standard dock-to-dock delivery, or when
you need delivery to a specific location within a site. The rack is transported as close
as possible to the desired location. If a stairway or a non-accessible doorway is
encountered, the rack is left there.
Highlights
• The palletized rack is unloaded by transportation personnel.
• Transportation personnel provide material-handling equipment.
B-2 HP 10842 Series Reference Guide
Page 64
• The rack is delivered to the desired location within the facility
(see “Limitations”).
• Delivery service is for a single rack.
Limitations
• If shipping a non-integrated rack, door widths and corridors must accept a
99-centimeters x 122-centimeters (39-inches x 48-inches) pallet.
• Door heights and corridors must be at least 2 meters (79 inches) tall to
accommodate the 10842 rack.
• A proper freight elevator must be available for deliveries to upper and lower
floors.
• Transportation personnel will not remove the rack from the shipping pallet.
• Transportation personnel will not remove the pallet or packaging.
Expedited Rack Delivery Service
Expedited Rack Delivery Service (Part No. 184449-001) is available in the rare
instances when air shipment of the rack is required.
Transportation Instructions
Highlights
• Special packaging, such as crating, is provided as required.
• Shipment is made by an air carrier selected by HP.
• Delivery service is for a single rack.
Limitations
• This service is available only in the continental United States, Alaska,

Transportation Instructions
Shipping/Delivery Considerations
The following precautions should be observed when receiving the racks and
components.
• A dock door is needed at the receiving site to accommodate the height and width
of the palletized racks.
• When shipping a rack, the 99-centimeters x 122-centimeters (39-inch x 48-inch)
pallet does not fit through a standard-width internal door, which is about
76.2 centimeters (30 inches) wide.
• The palletized 42U rack is approximately 216 centimeters (85 inches) high and
does not fit through a standard-height door.
• Do not lay the rack horizontally because the sheet metal can become distorted.
• Transport the rack as far into the building as possible while still on the pallet.
Then remove the rack from the pallet and roll the rack on its casters, being
careful to keep the rack from tipping. Ideally, the palletized rack should be
moved to its final destination and then removed from the pallet.
