Warning!
For installations in computer rooms with overhead power supplies, the maximum available
power cable length when routed to the top of the rack is approximately 36". Never extend the
power cable emerging from the rack in any way. If you need to supply power from overhead
outlets, relocate the power supply outlets so that they are closer to the racks.

1.6.5 Data and Communication Connections

An HP Cluster Platform has an administration network with a dedicated ProCurve switch that
has capacity for an additional external networking connection. You can use this ProCurve switch
to connect to your local area network (LAN) and wide area network (WAN). Depending on
which communications mode and networking method you intend to use, plan to order appropriate
cables and options and to place a network receptacle at a suitable location.
Consider the following topics when planning your connection:
Bandwidth
Refer to the installation and getting started guide for the specific model of HP ProCurve switch
that is used in your cluster. The switch documentation defines any specific restrictions, cable
type definitions, and cable wiring data.
Topology
The following networking connection methods are supported:
• Gigabit fiber-optic connection to backbone
• Straight-through or crossover connection (patch) to a network card installed in a server
• Connection to a LAN CAT-* receptacle
Other than creating a connection to your LAN, you cannot utilize any unused ports in the cluster's
administration switch.
TCP/IP Addresses
The cluster's network addresses are configured during software installation. See the software
documentation for information about how you can determine these addresses.

1.7 Power Supply Planning

Proper design and installation of a power distribution system for a cluster requires specialized
skills. Those responsible for this task must have a thorough knowledge and understanding of
appropriate electrical codes and the limitations of the power systems for computer and data
processing equipment. In general, a well-designed power distribution system exceeds the
requirements of most electrical codes. A good design, when coupled with proper installation
practices, produces the most trouble-free operation. A detailed discussion of power distribution
system design and installation is beyond the scope of this document. However, electrical factors
relating to power distribution system design and installation must be considered during the site
preparation process.
