Enabling power starts a sequence of blinking LEDs. Also, the
Niagara logo on the cover illuminates whenever power is applied to the controller.
Prerequisites: Power and ground wiring to the controller are ready. See wiring “Earth ground and power.”
- To apply power, do one of the following:
- Insert the two-position 24V power connector plug.
- Insert the barrel plug of the wall-mount AC adapter (WPM-8000) into an outlet.
- Check the BEAT (heartbeat) LED.
After power is applied, during bootup, the “BEAT” LED flashes at rate patterns indicated in the table below. The patterns
communicate status of the bootup process in terms of system state, niagarad, and station. When bootup completes and the heartbeat
led shows pattern
B then the controller is ready for network communication.
| Pattern |
Blink pattern |
System state |
Niagara daemon |
Station |
A |
200ms on / 200ms off |
system up |
niagarad starting |
no station running |
B |
200ms on / 1000ms off |
system up |
niagarad running |
no station running |
C |
1000ms on / 1000ms off |
system up |
|
station running |
- If, after applying power, the BEAT LED comes on (steady) and stays lit for over two (2) minutes, contact Systems Engineering
support for technical assistance.

For what to do next, refer to the “JACE-9000 Install and Startup Guide”, which explains how to commission a new JACE-8000 controller, that is, how to install the
Niagara 4 software, configure
Niagara platform settings, and install a
Niagara station.
