3.1.3 LED Indicators
The unit’s front panel LEDs indicate fault conditions and commanded or fault lockouts.
The LEDs do not indicate warnings or if the system test has not been performed. Use
the LEDs as a go/no go test or as a backup when you are not using AdminManager.
Upon power up, the Main Hub goes through a five-second test to check the LED
lamps. During this time, the LEDs blink through the states shown in Table 3-2, letting
you visually verify that the LED lamps and the firmware are functioning properly.
NOTE: Refer to Section 10 for troubleshooting using the LEDs.
Unit Status LEDs
The Main Hub status LEDs can be in one of three states, as shown in Table 3-1.
These LEDs can be:
steady green
steady red
blinking green/red (alternating green/red)
There is no off state when the unit’s power is on.
