Operational Space Requirements - NEC Express5800 1080Xd User Manual

Operational Space Requirements

Proper clearance around the cabinets must be provided for proper cooling airflow and
service of the system. Reduced airflow around equipment causes overheating, which can
lead to equipment failure. Therefore, the location and orientation of air conditioning ducts,
as well as airflow direction, are important. Obstructions to equipment intake or exhaust
airflow must be eliminated.
The locations of lighting fixtures and utility outlets affect servicing operations. Plan
equipment layout to take advantage of lighting and utility outlets. Do not forget to include
clearance for opening and closing equipment doors.
When considering the server service area space requirements, if other equipment is located
so that it exhausts heated air near the cooling air intakes of the computer system cabinets,
larger space requirements are needed to keep ambient air intake to the computer system
cabinets within the specified temperature and humidity ranges.
Space planning should also include the possible addition of equipment or other changes in
space requirements. Equipment layout plans should also include access provisions for the
following:
Routing data and power cables
!
Air conditioning ducts, filters, lighting, and electrical power hardware
!
Power conditioning equipment
!
Cleaning and maintenance of cabinets.
