Data Cabling Principles Used in Determining
Rack Locations
A series of positioning rules are used in the HP rack configuration tools to help
determine where each component is placed in multiple rack layouts.

Key Cabling Guidelines Used in Developing a Rack Layout

The following discussion is intended to support your understanding of how your
rack order was arrived at. It also discusses how rack layouts affect the attachment
and routing of cables.
This is a summary of key cabling guidelines. For complete details, see the HP
rack configuration tools located on the worldwide web.
Key guidelines help you to ensure that:
component placement from rack to rack is consistent
the cables supplied with components will reach between them as intended
there is provision for a "cable management loop" so that the HP NetServer
can be extended for service by trained personnel
cables are neat, and routed in a workable manner in cases where supplied
cables are not long enough for a cable management loop (which may
include those supplied with the video monitor and the UPS)
power supplies and distribution units supplied with the r ack assembly are
correctly installed to meet requirements for power, current, and number of
receptacles

Placement Considerations Due to Data Cable Lengths

Data cable lengths limit how far components can be located away from
one another. Components can be slightly nearer to or further from the
server. This depends upon whether the cables are routed to the left or to
the right side of the rack after being connected with the server. And this
in turn depends on cable guide placement.
