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 component 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.
Populating your new rack
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.
Apply the following rules to the physical placement of components in the HP V142 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
