Status Indicators
The back of the terminal has two indicators to identify system status:
• STS indicator (green) indicates that the terminal is on and running
• ERR indicator (red) indicates hardware and firmware faults
At startup, the STS and ERR indicators flash on and off, then the STS
indicator flashes to signal progress during startup. If the indicators remain off,
check the power cable.
After a successful startup, the STS indicator remains on.
The table shows indicator states if the terminal stops during startup.
