Flooring
NS2300 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 racks 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 weight of the
installed system, individual racks, and enclosures as they are moved into position. To determine
the total weight of the installation, refer to
“Rack and Enclosure Weights With Worksheet”
For your site’s floor system, consult with your HPE site preparation specialist or an appropriate
floor system engineer. If raised flooring is to be used, the rack is optimized for placement on
24-inch floor panels.
Dust and Pollution Control
NS2300 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 NS2300 System
WARNING!
A fully populated rack is unstable when moving down the unloading ramp from its
shipping pallet. A falling rack can cause serious or fatal personal injury.
Ensure:
√
There is adequate space to receive and unpack the system from shipping cartons and pallets and to remove
equipment using supplied ramps. For physical dimensions of the system equipment, refer to
Enough personnel are present to remove and transport each rack to the installation site.
Tiled or carpeted pathways have temporary hard floor covering to facilitate moving the racks which have small
casters.
Door and hallway width and height, the floor and elevator loading, accommodate the system equipment,
personnel, and lifting or moving devices. If necessary, enlarge or remove any obstructing doorway or wall.
