Status Indicators The back of the terminal has two indicators to identify system status:
•
STS indicator (green) indicates that the terminal is on and in use
•
ERR indicator (red) indicates hardware and firmware faults
At startup the STS and ERR indicators blink on and off, then the STS indicator
blinks to signal progress during startup. If the indicators remain off, check the
power cable.
After a successful startup, the STS indicator remains on.
Table 23 shows indicator states if the terminal stops during startup.
