8 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.
9 Required Software The Pressure Node installation requires the installation of the following SynapSense software: • • Web Console™ MapSense™ (including optional Active Control™ software with MapSense project .dlz file exported to the Web Console) Installation of SynapSense software generally takes place prior to hardware installation. This prevents redundancy of hardware verification activities.
10 Installing Pressure Nodes General Installation Guidelines Ensure software installation and required file exports before installing hardware Be consistent. • Match all node installations in appearance to ensure optimum data collection Be neat.
11 Preparing to Install the Pressure Node Hardware The SynapSense Field Engineer is responsible for completing these steps to confirm installation readiness: Assure the following steps are complete: a. Required software is installed and configured. b. Gateways are installed and powered on. c. All products and tools necessary for installation are on site. Verify the receipt of quantities and contents listed on packing/shipping list found in Box 1. a.
12 Installing Pressure Node Kits This section provides the steps for installing Pressure Nodes. After installing the Pressure Nodes, see Validating and Commissioning the Pressure Node Installation to validate the installation and commission pressure nodes. See Inspecting the Installation to complete the installation. In all configurations, hose lengths should not be excessive (short or long) and routing is smooth. Avoid hard turns and kinks.
13 Cabinet/Floor to Subfloor Pressure Nodes located under the cabinet on the tile floor have one hose/diffuser inserted up through a hole in the cabinet floor and routed to the side of the server (away from fans). The second hose/diffuser routes through a hole in the tile floor and is secured to the stanchion with a plenum-rated zip tie.
14 Cabinet and Subfloor Installation Perform the following steps to install a Pressure Node in or underneath a cabinet: 1. Prepare and route the diffuser hose. a. Determine Pressure Node location (inside or underneath cabinet) b. Determine necessary lengths for the low- and high-pressure hoses: low pressure hose length one (1) ft. maximum; high pressure hose length three (3) ft. maximum. Otherwise, cut to fit hose. c. Cut diffuser hose using scissors or utility knife. d.
15 g. Route the non-diffuser end of the long hose through the hole in the tile floor. h. Route the short hose (already attached to Pressure Node) through hole in the cabinet floor. i. Using gentle but firm pressure, attach the long diffuser hose to the high-pressure inlet (+) on the Pressure Node. 2. Activate, position, and secure the Pressure Node. a.
16 4. Route the low-pressure (short) hose to the side of the server so the diffuser is in still air. Ensure hose routing is under existing wires and cables to prevent inadvertent disconnection. 5. If needed, secure short hose/diffuser with cable clip to prevent hose from moving freely. 6. Remove tools and debris from cabinet and subfloor areas. 7. Replace tile over subfloor cavity.
17 Overhead Plenum Installation Perform the following activities to install a Pressure Node in an overhead plenum. 1. Prepare diffuser hose and plenum. a. b. c. d. Determine Pressure Node installation location on the wall near the overhead plenum. Remove plenum cover. Clean area where Pressure Node will reside with alcohol wipes. Allow area to dry thoroughly.
18 3. Route the hose, replace vent, and clean area. a. Place the long hose a minimum of six inches inside the plenum ducting. Ensure diffuser is not in a “T” junction as pressure reading will not be accurate. b. Remove adhesive cover on a cable clip and install inside the plenum duct near the long hose. c. Secure long hose to cable clip. d. Secure short hose, if dangling with cable clip installed to the wall or ceiling. e. Replace vent cover on plenum. f. Remove tools and debris from area.
19 Replacing an Existing Pressure Node 2 with a New Pressure Node 3 The new SynapSense Pressure Node 3 is supported in Release 7.4.1 and later. To replace an existing Pressure Node 2 with a new Pressure Node 3, use the following steps. Note: A user needs to have privileges to replace configuration and export projects in MapSense. 1. Open MapSense as an Administrator. 2. Open the project file. 3. Set the MapSense user level to Expert. 4. Locate the old Pressure Node 2 in the MapSense project 5.
20 Validating and Commissioning the Pressure Node Installation Validate and commission the Pressure Node installation by activating the Pressure Node and confirming node communication with the SynapSense Web Console software application. Refer to the Web Console User Guide for detailed information. Before beginning the following steps, first verify (with lead supervisor or installer) all necessary installation activities, including software installation and file exports are completed.
21 Pressure Node LED Status Lights Pressure Node 2 The Pressure Node 2 communicates status via three LEDs (Light Emitting Diodes), visible through a translucent plastic cover on the topside corner of the case. The following diagram shows the typical color sequences displayed as the node powers on and joins a wireless network. Typically, the sequence from OFF to Normal Operation may take 10 minutes to over an hour depending on the network environment in the data center.
