Cable Management Kits; Thermal Requirements - HP 245161-B22 - 10642 42U Rack Shock Pallet Best Practices Manual

Cable management kits

Due to the dynamic nature of the rack environment, the cabling of systems has very few hard rules.
Cable management kits provide an easy way to organize and route cables within racks. Several kits
are available as options to assist with cabling requirements.
Additional information on cable management kits is available at
HP general guidelines for cable management are as follows:
• Use eCo-Enterprise Configurator to fully plan the rack and server setup prior to installation.
• For good visual reference, do not install cabling until all equipment has been installed in the rack.
• Avoid dressing cabling tightly over sharp edges of railing or panels.
• Avoid pinching of cables between components.
• Avoid tight bend radii. Cables should never be bent tight enough to cause a crease in the
sheathing. Fiber cables must not violate their minimum bend radius – no exceptions.
• When securing cables inside the rack, the bundle should be dressed in such a way as to avoid
interference with installed components or rack side panels or rails.
• When possible, use all cable management arms included in component kits.
• For components that must be movable while Powered On, ensure a full range of motion is possible
without cable interference or disconnect. Cables dressed on management arms must be secured
enough to prevent movement into interference or pinch areas, yet not so tight as to cause binding to
the arm.
• Separate power and signal cables as much as possible. For example, dress all signal cables on the
Left side of the rack and all power cables on the Right side of the rack.
• Ensure that cabling does not impede the airflow to the rack-mountable servers or increase the
internal rack temperature beyond the specified maximum rating.

Thermal requirements

Equipment that is exposed to excessive heat may not operate correctly and may experience
abnormally high failure rates. The 10000 and 10000 G2 Series rack air flows from the front to the
rear of the rack. HP recommends that rack components only be installed on the front rails for many
reasons including proper airflow. Roof-mounted Fan kits (available for 10000 and 10000 G2 Series
racks) may help meet additional thermal requirements of rack-mounted equipment and are used to
keep the ambient temperature inside the rack within the specified operational limits of the equipment.
NOTE
800-mm racks include vertical filler panels for thermal management.
