Upon power-up, the HMI PC automatically starts Ubuntu (Linux) and loads the VC4™ HMI
program. After the startup sequence, the VC4™ HMI main screen opens as below. The start-up
time may take several minutes, and the default user is Viewer (R3).
Note: Any time the VC4™ system is powered up, loss of communications may cause
maintenance faults. "Acknowledge Notifications" on page 58 for instructions to clear faults.
