Dust and Pollution Control
NS2100 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 Hewlett Packard Enterprise
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.
For physical dimensions of the server equipment, see
“Dimensions and Weights” (page 65)
.
Operational Space
When planning the layout of the server site, use the equipment dimensions, door swing, and
service clearances listed in
“Dimensions and Weights” (page 65)
. 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. For information,

“Cooling and Humidity Control” (page 41)
