Configuration Factors
Before populating your new rack, you must 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 Custom
Builder, a powerful Web-based service enabling you to build, store, and export
end-to-end rack configurations. The latest version of the software is available on
the HP website (http://h30099.www3.hp.com/configurator/eco-
cb/custombuilder.asp).
Custom Builder Online Modes of Operation
Custom Builder has two modes of operation:
• Help-Me-Build-A-New-Solution 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-A-New-Solution-Myself Mode—Enables you to select the
individual devices that are required for your rack configuration
Configuration Factors 33
Component Placement
Apply the following rules to the physical placement of components in the HP
5642 Rack:
• Weight—Sort all of the components by weight, placing the heaviest
components at the bottom of the rack.
• KVM Switch—Mount the switch either behind the keyboard or within a
sidewall cavity to provide a 0U space solution.
• RKM—Install the RKM at a level that is the correct ergonomic position
where your shoulders and neck are relaxed.
• Monitor—Arrange the screen a minimum of 4Us above the keyboard tray.
• Rack-mountable flat-panel monitor—Select a position to accommodate the
desired viewing height (a minimum of 4Us above the keyboard tray).
• Balance—Be sure to balance the weight load between the racks, placing the
heaviest components at the bottom of the rack. 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.
For further information regarding component placement, refer to the Important
Safety Instructions that are shipped with the rack. Also, refer to the Safety and
Comfort Guide—Precautions for Server and Network Products on the HP
website (http://www.hp.com
) (search for Safety and Comfort Guide).
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.
34 HP 5642 Rack User Guide
• 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 installation of a 1U Keyboard
Drawer Rack Option Kit.
• 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 console switch is configured, use the CPU-to-
console switch cable included with the server. The standard distance between
the console switch and the keyboard, monitor, and mouse can vary by 3-, 7-,
12-, 20-, and 40-ft lengths.
NOTE: National electrical regulations governing the installation of
building wiring require that an appropriate cable, meeting fire-safety
standards, must be used any time cabling is routed:
• Through an overhead drop-ceiling
• Under 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 a U.S. plenum-rated (CL2P) cable,
contact your local HP authorized reseller to obtain any of the following
options:
• 149363-B21-20-foot plenum cable
• 149364-B21-40-foot plenum cable
• Baying Rack Option Kits—The number of baying kits needed to join a
series of racks is one less than the number of racks in the suite. Each baying
kit supplies parts to bay two cabinets on 600 mm (24 inches) center line
spacing.
• Side Panels—Only one set of side panels is required for each row of bayed
racks.
• Stabilizing Kit—A stand-alone rack requires a stabilizing kit.
Configuration Factors 35
Optimum Environment
Specific requirements for space, power, temperature, and airflow must be met to
provide optimum performance with minimum maintenance for your rack
environment.
For additional information, refer to the Best Practices document on the HP
website (http://www.hp.com).
Space Requirements
When deciding where to place your rack:
• At least 1,219 mm (48 inches) of clearance is needed all the way around the
pallet and above the rack to enable the removal of the packing material.
• At least 1,219 mm (48 inches) of clearance is needed in front of the rack to
enable the door to open completely.
• At least 762 mm (30 inches) of clearance is needed in the rear of the rack to
provide access to components.
• At least 380 mm (15 inches) of clearance is needed around a power supply to
facilitate servicing.
Power 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% of the branch
circuit AC current rating.
• If a UPS is used, the load should not exceed 80% of the marked electrical
current rating for the UPS.
36 HP 5642 Rack User Guide
This equipment must be installed in accordance with local and regional electrical
regulations governing the installation of information technology equipment by
licensed electricians. This equipment is designed to operate in installations
covered by the Nation 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 products rating label or user
documentation supplied with that option.
Temperature Requirements
To ensure continued safe and reliable equipment operation, install or position the
rack in a well ventilated, climate-controlled environment.
The operating temperature inside the rack is always higher than the room
temperature and is dependent on the configuration of equipment in the rack.
Check the TMRA for each piece of equipment before installation.
CAUTION: To reduce the risk of damage to the equipment
when installing third-party options:
• Do not permit optional equipment to impede airflow around the HP
5642 Rack or to increase the internal rack temperature beyond the
maximum allowable limits.
• Do not exceed the manufacturer’s TMRA.
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 enable ambient room air to enter the
rack, and the rear door must be adequately ventilated to enable the warm air to
escape the rack. Do not block the ventilation apertures.
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, which can
adversely affect cooling within the rack. Cover these gaps with blanking panels.
Configuration Factors 37
Multiple Racks
Increasing space and stability, HP 5642 Racks can be bayed together by
installing the HP 5642 Baying Rack Option Kit. The HP 5642 Baying Rack
Option Kit joins multiple racks of the same series, height, and depth.
Observe the following tips when using multiple-rack configurations:
• The stabilizing kit is 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.

Grounding Methods to Prevent Electrostatic Discharge...............................................................52
Preventing 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 staticsensitive devices. This type of damage may reduce the life expectancy of the
device.
To prevent electrostatic damage:
• Avoid hand contact by transporting and storing products in static-safe
containers.
• Keep electrostatic-sensitive parts in their containers until they arrive at staticfree 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.
52 HP 5642 Rack User Guide
Grounding Methods to Prevent Electrostatic
Discharge
Several methods are used 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 an
authorized reseller install the part.
For more information on static electricity or assistance with product installation,
contact your authorized reseller.
