Installing your hardware

The following sections describe the setup of different hardware components that constitute the smartengine deployment. For detailed specifications of the hardware including single line diagrams and data sheets, please visit the product website1.

Setting up a smartengine

The smartengine1 is the workhorse of the smartengine platform delivering power and communication with sensors as a 48-port, 1.5 RU rack mountable device. The smartengine is designed to deliver fixed current DC power to light fixtures, eliminating the need for any active power conversion components in the plenum.

Front Panel

The 48 front panel ports can be used to connect to the smartengine endpoints.

  • The smartengine has one system LED that conveys the status of the system.
  • Each port has an associated LED. These are turned off by default, and can be activated for 30 seconds by pressing the show status button on the top left.
  • The network ports have associated LEDs that indicate the link status and activity.

Refer to Troubleshooting for more details on the LED indicators.

Network Ports

The two ethernet ports on the right can be used to communicate with the engine over IP. The primary port (labeled LAN) must be connected to the network to which other engines are connected. The secondary ethernet port (labeled AUX) has a fixed IP address ( and can be used to configure and setup the engine. It cannot be used to communicate with other systems in the network.


To ensure the smartengines operate continuously as designed, a dedicated branch circuit for the smartengines is recommended, preventing other loads on the same circuit from drawing too much current from the branch circuit. Provide the smartengine with a suitable disconnect in the input power distribution so that AC power is safely removed during servicing. The wiring must meet all NEC, state, and local electrical codes and needs to be installed by a qualified electrician.

smartengines are available as 200–250 VAC and 277 VAC power input versions. The power sockets can be found on the back side of the smartengine.

Mounting Options

The smartengines are capable of driving fixtures placed at a maximum cable length of 328ft/100m (wire-length) away from the engines. For office installations, that location is most likely an IDF closet. For data centers, the engines will likely need to be in the data hall itself. Space in the racks has to be allocated for the engines, patch panels, and for cable management. The smartengines can be mounted in any two or four post 19” racks.

In addition to the vertical and horizontal rack mounting options shown above, the smartengines may be secured to a wall using special wall mount kit.

Setting up a smartdirector

The smartdirector1 is a 1RU server appliance that should be mounted in the rack using the supplied kits. There are three ethernet ports in the back of the device:

  1. Primary Port (labeled Gb1). Connect this to the smartengine network.
  2. Secondary Port (labeled Gb2). Use this to connect to the system directly from your laptop using the address.
  3. Out of band management port (labeled iDRAC). This port is not used for smartengine functionality. It is available as a way to administer the system hardware remotely.

Installing a smartengine endpoint

The smartengine endpoints may be sensors, gateways or wall controllers, and are installed in the building in the ceiling or into the wall. Depending on the type of ceiling appropriate mounting schemes and accessory kits should be used for the fixture and sensor.

Mounting Considerations

sensor mount  

smartsensor/gateway mounting (fixture requirements will differ)

Identify the ceiling structure and identify all unique installation environments, including, but not limited to:

  • Drop Ceilings
  • Suspended Ceilings

    • Determine if the sensor and gateway will be attached to fixtures somehow or mounted in the ceiling
  • Uni-­struts

    • Determine if the sensor and gateway will be attached to fixtures somehow or mounted to the uni-­‐strut.
    • Specify how the fixtures will connect to the uni-­struts. Make sure that the appropriate mounting hardware has been ordered from the fixture manufacturer.
  • Hard Mounted

    • When/where will the sensors and gateways be installed? Is there appropriate access in the event that something needs to be replaced?
    • Does the fixture manufacturer have a hard-­mount kit?
  • Drywall Ceilings

    • Is there access to the top of the fixture from underneath? For some downlights, you can reach through the downlight. For others, there has to be another access point.


Note that the smartgateways and smartsensors are not damp rated. They cannot be used in an outdoor or moisture rich environment.


Sensors should be mounted 15’ or below to capture minor motion. Please contact for any application above 15’. These are to not be placed above 20’ if motion is to be detected and not above 14’ if minor motion is to be detected.

Connecting the ports on the smartsensor or smartgateway


The smartsensor or smartgateway has separate RJ45 ports marked for connecting to the smartengine and lighting fixture.


The connections from a smartengine gateway must terminate at the ports on the same smartengine. In other words, a single smartgateway cannot be connected to different smartengines. Doing so would result in gateway not being operational on any of the smartengines.

A smartgateway has an additional port to connect to a smartsensor module (optional).

The LED indicator on the sensor can be used to diagnose connection issues.

OffThe sensor has been configured and is fully functional, or there is a wiring problem that is preventing the smartengine from being able to communicate with it.
RedThe sensor is able to communicate with the smartengine and but has not been commissioned (assigned to a space/room where it belongs)
Alternate between Red and OffThe sensor is communicating with the smartengine and but the fixture associated with it has a issues preventing it from being discovered completely by smartengine
Flashing Green/GreenUsed when some software controls like blinking or flashlight naming are activated.

Lighting controls using a standard SPST or SPDT switch

smartsensor GPIO connection The smartsensor1 can be connected to a SPST or SPDT Momentary Contact (Center-off) switch using 20AWG solid core wire. When connected to an individual sensor in a designated room, the light switch will control all of the fixtures in that room manually. The GPIO ports are on top of the smartsensor as seen in the picture. This connection will not take up an additional smartengine port.
