3.1.3 LED Indicators
The unit’s front panel LEDs indicate faults and commanded or fault lockouts. The
LEDs do not indicate warnings or whether the system test has been performed. Only
use the LEDs to provide basic information or as a backup when you are not using
AdminManager.
Upon power up, a 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.
Main Hubs ship without a band programmed into them. After the equipment is
installed, cables connected, and powered up, an unprogrammed Main Hub LEDs dis-
plays as follows:
•
MAIN HUB STATUS LED: Red
•
LINK LED: Green
•
E-HUB/RAU LED: Red
If the LEDs do not display as above, refer to Table 3-1 on page 3-5, Table 3-2 on
page 3-6, and/or Section 9 for troubleshooting using the LEDs.
