Understanding the Status LEDs
The Ampt-CU has three status LEDs. When input power is first applied to the Ampt-CU, all
LEDs are on continuously for several seconds. Then the Com LED flashes amber while
software is booting. Once boot up is complete and the Ampt-CU is operating normally, both
the Power and Com LEDs are on solid green.

Fault Continuous Red When this LED is on solid red after the boot up process, a fault condition
has been detected. Cycle the input power. If this LED is still on after the
Com LED finishes flashing (during the boot process), then contact Ampt
support.
