Recovering factory defaults

The process of recovering factory defaults returns the Edge device to the state it was in when it shipped from the factory. This procedure describes the steps to recover factory defaults when using a terminal emulator program to access the device’s system shell menu.
Prerequisites:
  • A USB-to-micro USB cable (same cable as that used to connect a smart phone to a computer) connecting the controller to your PC. The Debug port on a controller is a standard Micro-A type USB port used to access the serial shell.
  • A terminal emulator (system shell program), such as PuTTY, installed on your PC.
 CAUTION: Recovering factory defaults removes all platform and station data in the device. Be sure to backup data prior to performing this procedure. 

Following are a couple of scenarios for which you might choose to recover factory defaults:

  • While commissioning a brand new Edge device, you make an error entering the default platform daemon credentials or passphrase. The result is that you cannot commission the controller. In this scenario, your only option is to recover the factory defaults.
  • When decommissioning the Edge device, a best practice to follow is recovering the factory defaults in order to wipe all of the platform and station data in the controller.

The figure with numbered call-outs, shown here, indicates the position of USB port and pushbutton switches.

1 STAT LED Status LED, illuminated while controller is powered.
2 BEAT LED Heartbeat LED, normally 5Hz, 50% duty cycle. Fast blink during boot process.
3 DEBUG Micro-A USB port for serial debug communications
4 FACTORY RESET Push-button switch to initiate a return to factory default settings
5 RESET Unlabeled push-button switch (located in the recessed cavity) to initiate physical reset of the device.
  • The DEBUG port is a standard Micro-A type USB port for serial debug communications to the device.
     NOTE: Login requires administrator level platform credentials. 
  • The RESET button does an immediate shutdown of the device. It is the equivalent of removing power.

Perform the following steps:
  1. Ensure that the device’s power is off.
  2. Press and hold down the Factory Reset button as you power up the device. You will see one of the following:
    1. Status LED blinks at a fast rate (5Hz)
    2. If you have the serial shell you will see a prompt to release the button:
      “Restore button press detected. Please release button to initiate factory restore.
      Restore mode is set!
  3. Release the button to proceed with the factory restore process.
     NOTE: The FACTORY RESET button must be released within 5 seconds of the fast blink. 
  4. When the Edge device powers up, login with default credentials to proceed.
     NOTE: Factory restore involves several reboots. During reboot, the BEAT LED blinks at a rapid rate. When the BEAT LED blinks at normal rate login with default credentials. 
     CAUTION: Do not remove power from the device while the BEAT LED blinks at a rapid rate since this causes physical stress on the equipment and prevents good connections between the device and I/O modules.
