2 OVERVIEW
2.1 Introduction
The Vertiv™ Wireless Sensor Network (WSN) uses a gateway and sensor nodes that use a direct sensor to gateway
communication path for environmental monitoring. Each application is different in that the final installed system
performance is dependent on a number of factors that are not within Vertiv's control.
The sensor nodes contain multiple on-board or connected sensors allowing for multiple data points to be communicated
wirelessly back to the gateway to be aggregated and displayed. Selected data is communicated out of the gateway to
connected systems using wired means. The system can be controlled or monitored with system or user configuration values.
This solution offers a join process where advanced sensor nodes can be easily and securely added to the gateway using
auto-discovery—programming cables are not required. After sensor nodes have been added securely, the network can be
locked down to prevent unknown devices from entering the network. The gateway can support connectivity and
communication with up to 300 sensor nodes on a fully populated system.
For enhanced environmental sensing capabilities, WSN-FLEX sensor nodes provide
•Temperature and humidity control
•Dual programmable digital/analog IO
•An accelerometer
•A Piezo buzzer
The sensor nodes can be powered using three methods with automatic failover between all power methods to increase up
time and availability, prioritized in the following order:
1. Standard local micro-USB power source
2. External battery pack
3. Internal batteries
When sensors are joined to the gateway, communication begins automatically and data is made available via SNMP
protocol and to an API to externally connected clients.

5.2 Equipment Installation and Recommendations
NOTE: The technology used in the Vertiv™ WSN is a direct sensor to gateway communication path. Every application
is different in that final installed system performance is dependent on a significant number of factors not within the
control of Vertiv. The guidelines provided in this section are recommendations only and Vertiv makes no guarantee
for system performance in every application.
NOTE: Gateways and sensors are intended for indoor use only.
5.3 Gateway Installation
5.3.1 Location
•The final location should be near the center of the final installed sensor field.
•Mount at a height that minimizes the number of obstructions near the antenna, between the gateway and
sensor nodes.
•Align the sensor to gateway communication paths in a parallel alignment to the direction of rack rows as much
as possible to reduce perpendicular obstructions to the wireless signal.
•In high density data center environments, a maximum diameter of roughly 400 ft. (with gateway at the
center)is recommended. Open environments and applications with clear line of sight support longer distances.
•The gateway antenna should be adjusted such that it is perpendicular to the floor.
5.3.2 Gateway Physical Description
The gateway electronics are enclosed in an aluminum extrusion with abs end caps. The enclosure has connections for power,
Ethernet, and an antenna. The unit is designed to be mounted on a DIN rail bracket, if desired. The DIN rail bracket may be
easily removed by removing the four screws attached the DIN rail to the back of the enclosure. Four rubber feet are
provided with each gateway that can be applied if the gateway is to be placed on a table top.

5.3.3 Gateway Mounting Considerations
This section provides information to properly mount the gateway and making electrical connections, including the wiring,
grounding, and host system connections.
The unit itself is not designed for outdoor mounting without a suitable enclosure. The gateway should be mounted in an
approved electrical enclosure inside of a building and in a location that allows convenient access to the host system
network (process control network) and to the wireless field device network. The location of the unit must protect the
gateway from contamination and moisture.
5.3.4 Mounting the Gateway
The gateway can be snapped onto a standard 35 mm DIN rail system.
To clip the unit onto the DIN rail:
1. Tilt the unit at a slight angle to allow the lower lip of the chassis to catch the bottom of the DIN rail.
2. Apply simultaneous pressure up and towards the DIN rail to snap the back of the unit securely onto the rail.
To remove the unit:
1. Lift the gateway base station while also pulling the top away from the DIN rail.
Vertiv | Vertiv™ Wireless Sensor Network (WSN) Installer/User Guide
14

2. Once the unit is released from the DIN rail, slide the entire unit down until the bottom hooks are clear of the DIN
rail.
The gateway can also be placed onto a solid surface by removing the DIN rail bracket (four screws) and installing the four
rubber feet.
IMPORTANT! Follow FCC recommendations for RF exposure warning to maintain a minimum of 7.9 in. (20 cm)
clearance for bystanders and antenna co-location.
Screw the antenna into the SMA plug on top of the gateway. Ensure the antenna is perpendicular to the ground for best
reception.
5.3.5 Application
Once power is applied to the gateway, the gateway will boot up and be ready to access either of the RJ45 CAT5/6Ethernet
ports on the bottom of the gateway. The gateway is available when the blue status LED on the front is active.
5.4 Electrical Grounding
The DIN rail should always be grounded in accordance with national and local electrical codes. The most effective
grounding method is a direct connection to earth ground with minimal impedance. Grounding to the gateway is
accomplished through the DIN rail clip on the back of the gateway. The negative power lead on the DC input cable is also
internally connected to the gateway enclosure.
5.5 Connecting and Powering the Gateway
Physically connect the PC or laptop to the gateway with an Ethernet cable and power the gateway using these steps:
1. Connect one end to the Ethernet port of the PC or laptop.
2. Connect the other end to one of the Ethernet ports on the gateway.
3. Connect the locking barrel connector to the gateway using the supplied DC power supply.
NOTE: The auxiliary power cable may also be used. If using the auxiliary power cable, see the Using the Auxiliary
Power Cable below.
4. Plug the power supply into a standard 110/120V AC receptacle.
5.5.1 Using the Auxiliary Power Cable
If you are using the auxiliary power cable, complete steps 1 and 2 above and perform this step:
•Connect the locking barrel connector to the gateway and connect the wire leads to a 12.0VDC power supply.
IMPORTANT! Pay attention to the white lead marked +to indicate the positive connection.
The Gateway operates from an input voltage of 10.0VDC to 30VDC.
IMPORTANT! All agency approvals were conducted at an input voltage of 12.0VDC. Vertiv does not suggest operating
the gateway with an input voltage other than 12.0VDC as the compliance is not guaranteed.
5.6 Ethernet Connections
The Gateway is equipped with two 10/100 base-TX Ethernet communication ports. These connections can be used to access
the gateway’s web interface. In addition, these ports can be used to communicate BMS procotols like SNMP.
5 Hardware Installation 15

5.7 Configuring the Gateway
The gateway boot-up takes approximately 2-1/2 minutes to complete.
After powering the gateway on, the green power LED will be illuminated but the blue status LED will not be lit until the
boot-up sequence is complete.
Once the blue status LED is lit, you can log onto the gateway for the first time and begin configuration. The following items
need to be configured:
1. Log into the gateway for the first time using:
User = admin
Password = admin
Changing this default password is required to first access the gateway for any viewing/configuration.
2. Time settings. Gateway time settings and time stamps are stored internally as UTC time. The gateway allows
time setting via manual entry in the configuration web page.
3. IP network settings. Prior to the gateway being installed and connected to a live network, it should be
configured with an IP address if the network requires an IP address other than the defaults provided in Default
Gateway Network Settings on page7
IMPORTANT! Initial access to the gateway must occur using one of the default IP addresses. Once the gateway's IP
address has been changed, communications to the web interface will be lost if it is connected to the port that is being
changed. If this occurs, the PC or laptop connected to the gateway must be moved to the same subnet that the
gateway was moved to before access can be re-gained.
5.8 Orienting the Antenna
The antenna is a dipole. The antenna should always be adjusted such that it is perpendicular to the ground. In this
orientation, the transmit and receive pattern allows it to essentially function as an omnidirectional antenna.
