   1      CHAPTER 1. Introduction This chapter provides an overview of the Subfloor EZ Node hardware, introduces this installation guide, and lists general warnings and precautions.  In this chapter:  Overview  About this Installation Guide  Warnings and Precautions
Subfloor EZ Node Hardware Installation Guide Version 1.0   2    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.  About this Installation Guide This document provides guidelines and instructions for installing SynapSense® Subfloor EZ Nodes to designated service companies or the customer. The intended audience for this document consists of customers or partners of SynapSense Corporation, SynapSense installers, and SynapSense installation teams. SynapSense “Tier 1” training is highly recommended for installation engineers and others who are installing SynapSense hardware or closely involved with the installation of data center optimization equipment.
