Getting Started
Required Hardware
The required hardware for this installation is included in the Pressure Nodes kit, which
contains these components.
•
One wireless Pressure Node module with four
installed batteries
•
One 5-foot long air hose fitted with diffuser
tips on both ends. The hose is cut into two
pieces, one for each Pressure Node inlet.
•
Zip ties, 3M Command Strips, cable clips (not
shown)
PLACE LOW-PRESSURE DIFFUSER IN STILL AIR.
Warning:
Position the low-pressure diffuser (-) in an area of still air. Rapidly moving air
provides incorrect pressure readings. Keep diffuser at least one foot away from server fan
airflow, holes in the subfloor, or perforated floor tiles.
PLACE HIGH-PRESSURE DIFFUSER AWAY FROM OBSTRUCTIONS.
Warning:
Position the high-pressure (+) diffuser away from air turbulence in the subfloor
cavity (for example, large cable bundles, electrical boxes, wall outside corners, bends or
edges, and concrete support columns).
BE CAREFUL WHEN REMOVING HOSES FROM A PRESSURE NODE.
Warning:
Hose connections on the Pressure Node are brittle, particularly in subfloor
cavities or cold aisles where chilled air is present. See Appendix A for more information.
