Overview
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 industry-
standard 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.
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

• Interchangeable front and rear doors that allow the rack to be used in
server/storage or switching applications
NOTE: Customers wanting to utilize the 10842 rack exclusively for switching devices,
such as routers and switches, have two options:
• Interchange the front and rear doors to make use of the mounting rail front
justification, allowing room in the front of the rack for cabling.
• Move the front vertical rails back allowing the switching devices to be mounted on
both front and rear sets of internal mounting rails.

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 www.hp.com.
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.
Installation Sequence Summary
The following is a recommended sequence of events for the most efficient
installation of your rack and components.
1. Download the Rack Builder Online software from the HP website and install it
on your system. Using the Rack Builder Online software, plan the rack
component location and installation sequence.
2. Select a location to set up your rack. This location should be as close as possible
to the permanent site for your rack.
3. Remove the packaging from the rack and verify the hardware contents.
4. Remove any doors and panels from the rack to provide easy access.
5. Stabilize the rack.
6. Bay multiple racks together.
7. Install products such as Power Distribution Units (PDUs) or switch boxes in
sidewall locations.

Configuration Factors
Before populating your new rack, it is important to plan the placement of each
component. Factors of each component, such as weight, accessibility, power,
temperature, and airflow requirements, affect installation order and component
placement in the rack.
Rack Configuration Software
To help you plan your rack configuration more efficiently, HP provides Rack Builder
Online, the browser-based rack configuration tool. The latest version of the software
is available at www.hp.com.
Rack Builder Online Modes of Operation
The Rack Builder Online software has two modes of operation:
• Help Me Build It Mode—Includes a simple interview session to help determine
your rack and component needs, as well as the necessary power products and
rack assembly devices needed to complete the final rack assembly
• Let Me Build It Mode—Lets you select the individual devices that are required
for your configuration

Rack Builder Online Features
The Rack Builder Online software offers the following features.
• Multiple-Rack Configuration—Allows up to six racks to be viewed and
configured onscreen in one session
• Graphics—Uses graphical representations of the systems to illustrate the U
height that each component occupies
• Labeling—Aids in rack maintenance and configuration by allowing individual
racks and components within a rack to be labeled
• Drag & Drop—Allows the graphics of devices in a multiple-rack configuration
to be dragged and dropped between racks
• Reports—Provides reports on rack configuration labeling and rack suite graphics
for configurations that include multiple racks

build it. Then print out a report and use it as your shopping list. After your rack
configuration is in place, use Rack Builder Online to assist you in maintenance and
upgrades.
Refer to the documentation accompanying Rack Builder Online for installation and
use of the software features.

Codename: Part Number: 284358-002 Last Saved On: 10/11/02 4:11 PM
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
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 CONFIDENTIAL
Writer: Amy L. Laffitte File Name: c-ch2 Configuration Factors
Codename: Part Number: 284358-002 Last Saved On: 10/11/02 4:11 PM
• 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 Plenum-
rated 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.
