Review the Sales Order
Customer sales order information is available through the Support
Connect system and through the WWOMS (World-Wide Order
Management System). Carefully review the sales order information to
assess:
• the number of integrated systems ordered
• the number of peripheral cabinets ordered
• the number and type of PDUs
• special configuration requirements
•deliverydates

Plan the Site Visit
After a careful review of the sales order, a Hewlett-Packard Site
Preparation Specialist will make arrangements for a preliminary on-site
meeting. The purpose of this meeting will be to discuss the site planning
and preparation needs including electrical, mechanical, and physical
system requirements.
Ideally, this meeting should be scheduled at least 60 days prior to the
solution delivery date for the equipment (see Develop the Schedule). If
that is not feasible, it should be planned for the earliest possible date.
Key contact information for both the Hewlett-Packard Site Preparation
Specialist and the customer should be recorded and kept for reference:
The Hewlett-Packard Site Preparation Specialist and the customer
contact should discuss and agree as to any other participants included in

Visit the Site
During the preliminary site visit, it is important that the
Hewlett-Packard Site Preparation Specialist and the customer
representative accomplish the following major tasks:

Verify system complicity with regulatory
standards
The following checklist should be filled out during the preliminary site
visit to ensure regulatory standards are met and that any site
deficiencies are identified:

Develop the Schedule
The following schedule lists the sequence of events for an ideal system
installation.
• 60 days before installation
— Floor plan design completed and mailed to Hewlett-Packard
• 30 days before installation
— Primary power and air conditioning installation completed
— Telephone and data cables installed
— Fire protection equipment installed
— Major facility changes completed
— Special delivery requirements defined
— Site inspection survey completed
— Delivery survey completed
— Signed copy of the site inspection and delivery survey mailed to
Hewlett-Packard
— Site inspection and predelivery coordination meeting arranged
with a Hewlett-Packard Site Preparation Specialist to review the
inspection checklist and arrange a solution delivery schedule.
• Solution delivery date
— Final check made with an Hewlett-Packard Site Preparation
Specialist to resolve any last minute problems

Specify Hard Floor Requirements
A cable trough may be required when an rp7400 system is installed in a
computer room that does not have a raised floor. The power drops and
interface cables from the SPU are routed down through the cable guides
and into the cable trough.
The cable trough connects to the bottom of a power panel. It should be
sized to hold all cables and receptacles for the power drops that come

14
from the SPU and peripheral cabinets.

15
Specify Power Protection
The only supported HP PowerTrust UPSs are the 3.0kVA and 5.5kVA
models. These UPSs can provide power protection to a single rp7400
SPU. Recommendations for other manufacturers and models are not yet
determined.
HP rp7400 server power supplies may be plugged directly into the
customer’s site UPS. However, customers are advised against plugging
the power supply into an HP PowerTrust UPS and then connecting that
UPS to the site UPS.

Determine the ESD Requirements
Static charges (voltage levels) occur when objects are separated or
rubbed together. The voltage level of a static charge is determined by the
following factors:
•Typesofmaterials
• Relative humidity
• Rate of change or separation
Effect of humidity on ESD charge levels
The table following lists charge levels based on personnel activities and
humidity levels.
Static protection measures
Follow these precautions to minimize possible ESD-induced failures in
the computer room:
•Maintain recommended humidity level and airflow rates in
the computer room.
• Install conductive flooring (conductive adhesive must be used when

• Use conductive wax if waxed floors are necessary.
• Ensure that all equipment and flooring are properly grounded and
are at the same ground potential.
• Use conductive tables and chairs.
• Use a grounded wrist strap (or other grounding method) when
handling circuit boards.
• Store spare electronic modules in antistatic containers.
