Configure and Setup your Secure Edge Node

Power On, Bootup, and SSH in
  • Connect up the ethernet and 12V power. The unit is designed to run headless. You do not need a monitor, keyboard, or mouse. As shipped, the hostname is zymbit-dev and a user named zymbit can be used for SSH login. The default password for SSH is zymbit. Please change your password once you login. Console login has been disabled.
The total boot time as configured should take approximately 90 seconds from power on.
  • Monitor the Blue LED on the Zymbit SCM module. It will go through the following stages:
    • one slow blink: initializing the SCM
    • one -> two -> three -> four blinks: Supervised Boot is verifying the signed file information
    • rapid blinking: Supervised Boot successfully completed, booting underway
    • blinking stops: USB bus enumeration found SCM; may stay off for seconds
    • one blink every 3 seconds: zkifc has loaded and the system is ready to go
All necessary Zymbit software has been pre-installed. No further installation is necessary. The pre-installed image is encrypted and cannot be replaced via rpiboot in the field. Please contact support@zymbit.com for assistance.
Secure Compute Module

Inside the Secure Edge Node is the Secure Compute Module: a Zymbit Security Module + Hardware Wallet + Raspberry Pi CM4 integrated into a secure encapsulated module.
