EC-BOS-9 Install and Startup Guide Chapter 5 Troubleshooting
– You are logged into to the controller serial shell using a terminal emulator (system shell program), such
as PuTTY and the serial shell menu is visible on your PC.
CAUTION: Recovering factory defaults removes all platform and station data from the device. Make sure this is
what you intend before you follow this procedure.
To reset a EC-BOS-9 to factory default state:
Step 1 With the outer panel cover open, press and hold the SHUT DOWN button on the EC-BOS-9 contol
panel.

1 SHUT DOWN shuts down the controller and serves as the factory defaults recovery button.
2
STAT (status LED) blinks during recovery of factory defaults.
3
DEBUG port is a USB-C port for serial debug communications between the controller and serial shell run-
ning in the PC.
4
BEAT (Yellow); heartbeat LED that blinks at 1Hz during normal operation. Refer to “BEAT (Heartbeat)
LED” section for details.
Step 2 While still pressing the SHUT DOWN button, reboot the controller using one of the following actions:
• Add power to a powered off controller.
• Choose option 9 Reboot from the serial shell menu and enter “Y” at the confirmation prompt.
Reboot is initiated.
Step 3 Release the SHUT DOWN button 5 seconds after reboot is initiated.
Factory default restoration process begins.
When the BEAT LED blinks at normal rate the process is complete.
To setup the restored controller platform you will need to login to the serial shell using factory default
credentials.
Resetting platform credentials (EC-BOS-9)
Occasionally a situation will arise where you have a functional EC-BOS-9 controller but no valid credentials or
system passphrase. This could be due to a change in building ownership or control contractors. The Platform
Account Recovery feature provides you with a secure method of regaining access to the controller without los-
ing station data and configuration.
