NonStop NS2200 Series Planning Guide

The site floor structure and any raised flooring (if used) must be able to support the total weight of
the installed computer system as well as the weight of the individual cabinets and their enclosures
as they are moved into position. To determine the total weight of each cabinet with its installed
enclosures, see the weight worksheet for the server you are installing (Specifications for NonStop
NS2200ST Systems (page 142)).
Describing how to build a raised floor that can accommodate the weight of the server and that
complies with local regulations is beyond the scope of this manual. You or your installation provider
should investigate these requirements. The customer assumes all risk in the using the NonStop
NS2200ST system on a raised floor.
For your site’s floor system, consult with your HP site preparation specialist or an appropriate floor
system engineer.
Receiving and Unpacking Space
Identify areas that are large enough to receive and unpack the system from its shipping cartons
and pallets. Be sure to allow adequate space to remove the system equipment from the shipping
pallets using supplied ramps. Also be sure adequate personnel are present to remove each cabinet
from its shipping pallet and to safely move it to the installation site.
Ensure sufficient pathways and clearances for moving the server equipment safely from the receiving
and unpacking areas to the installation site. Verify that door and hallway width and height as well
as floor and elevator loading will accommodate not only the server equipment but also all required
personnel and lifting or moving devices. If necessary, the customer can elect to enlarge or remove
any obstructing doorway or wall.
For specific guidelines, see the specifications for the cabinets used in the system you are installing.
Operational Space
When planning the layout of the server site, use the cabinet dimensions, door swing, and service
clearances for the cabinet type(s) supported by the server you are installing. Because location of
the lighting fixtures and electrical outlets affects servicing operations, consider an equipment layout
that takes advantage of existing lighting and electrical outlets.
Also consider the location and orientation of current or future air conditioning ducts and airflow
direction and eliminate any obstructions to equipment intake or exhaust air flow.
Space planning should also include the possible addition of equipment or other changes in space
requirements. Depending on the current or future equipment installed at your site, layout plans can
also include provisions for:
• Channels or fixtures used for routing data cables and power cables
• Access to air conditioning ducts, filters, lighting, and electrical power hardware
• Communications cables, patch panels, and switch equipment
• Power conditioning equipment
• Storage area or cabinets for supplies, media, and spare parts
Dust and Pollution Control
NonStop servers do not have air filters. Any computer equipment can be adversely affected by
dust and microscopic particles in the site environment. Airborne dust can blanket electronic
components on printed circuit boards inhibiting cooling airflow and causing premature failure from
excess heat, humidity, or both. Metallically conductive particles can short circuit electronic
components. Tape drives and some other mechanical devices can experience failures resulting
from airborne abrasive particles.
For recommendations to keep the site as free of dust and pollution as possible, consult with your
heating, ventilation, and air conditioning (HVAC) engineer or your HP site preparation specialist.
