NonStop NS2200 Series Planning Guide

Flooring
NonStop NS2200 systems can be installed either on the site’s floor with the cables entering from
above the equipment or on raised flooring with power and I/O cables entering from underneath.
Because cooling airflow through each enclosure in the modular cabinets is front-to-back, raised
flooring is not required for system cooling.
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 modular cabinets and their
enclosures as they are moved into position. To determine the total weight of each modular cabinet
with its installed enclosures, see “Modular Cabinet and Enclosure Weights With Worksheet”
(page 82).
For your site’s floor system, consult with your HP site preparation specialist or an appropriate floor
system engineer. If raised flooring is to be used, the design of the NonStop NS2200 system modular
cabinet is optimized for placement on 24-inch floor panels.
Dust and Pollution Control
NonStop NS2200 systems 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.
Zinc Particulates
Over time, fine whiskers of pure metal can form on electroplated zinc, cadmium, or tin surfaces
such as aged raised flooring panels and supports. If these whiskers are disturbed, they can break
off and become airborne, possibly causing computer failures or operational interruptions. This
metallic particulate contamination is a relatively rare but possible threat. Kits are available to test
for metallic particulate contamination, or you can request that your site preparation specialist or
HVAC engineer test the site for contamination before installing any electronic equipment.
Space for Receiving and Unpacking the System
Identify areas that are large enough to receive and to 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.
WARNING! A fully populated cabinet is unstable when moving down the unloading ramp from
its shipping pallet. Arrange for enough personnel to stabilize each cabinet during removal from
the pallet and to prevent the cabinet from falling. A falling cabinet can cause serious or fatal
personal injury.
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, enlarge or remove any obstructing doorway
or wall.
All modular cabinets have small casters to facilitate moving them on hard flooring from the unpacking
area to the site. Because of these small casters, rolling modular cabinets along carpeted or tiled
pathways might be difficult. If necessary, plan for a temporary hard floor covering in affected
pathways for easier movement of the equipment.
