Power on the Main Hub
1 Connect the AC or DC power as explained in “Making Power Connections” on page 120.
2 Turn on the power to the Main Hub and check that all the LED lamps
are functioning properly.
Upon power-up, the LEDs blinks for five seconds as a visual check that
they are functioning.
After the five-second test, LED states during power on will vary, depending on whether
Expansion Hubs are connected. Refer to Table 92 for possible combinations.
