Data Cabling References and Guidelines

A series of positioning rules is 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 summary of key cabling guidelines reflects information available from HP
rack configuration tools located on the Worldwide Web, path as follows:

"configuration tools"
Key guidelines help you to ensure that:
component placement from rack to rack is consistent
that the Cable Management Arm is correctly positioned and cables are
routed so that the HP NetServer can be extended for service by trained
personnel
power supplies and distribution units supplied with the rack assembly can
meet requirements for power, current, and number of receptacles

Cable Guide Placement Considerations Due to Data Cable Lengths

Data cable lengths limit how far components can be located away from one
another. Component placement 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. The left
side is recommended for mounting of the Cable Management Arm and
Cable Guides.
Cable Guide placement is determined by where the doors are hinged.
Doors can be mounted to swing from either side of the rack. Locate the
Cable Guide on the same side of the rack as the door hinge hardware.
Locate the PDU opposite the cable guide (if mounted vertically), on the
same side as the door latch hardware. PDU location can be changed to
allow other possible cable routing.
Data connections to devices are made with cables of various lengths. Be
sure to check the component cable length before mounting a component in
the rack.
