Subfloor EZ Node Hardware Installation Guide
Version 1.0

Overview
The Subfloor EZ Node is a wireless sensor that measures subfloor temperature and pressure differences
between the data center room and its subfloor cavities. The Subfloor EZ Node contains:
 A high-pressure (positive) barb and a high-pressure air hose fitted with a diffuser, which is
placed in the subfloor.
 Two low-pressure (negative) barbs connected to each other by a U-turn (a short hose bent in a
“U” shape), which allows the node to sense low pressure internal to the unit. If necessary, you
can remove the U-turn and attach a hose to the center barb to sense low pressure away from
the node.
 A thermistor connected to the node via a harness. This allows the node to sense temperature
away from the node.
Once installed and operational, the node transmits temperature and air pressure data to the Web
Console. Combined with data collected from other Subfloor EZ Nodes located throughout the data
center, operators use this information to adjust fan speeds and relocate perforated tiles to increase
CRAC/CRAH efficiency.
