portal. Check that the <OK> appears in the Status field.

Troubleshooting

Yellow LED (Link) is OFF

If the yellow LED (Link) is OFF after device discovery, a ZigBee RF
connection error may have occurred, or the ZigBee connection was
not established. Try the following troubleshooting actions:

Relocate the repeater closer to the master ZigBee device to
improve signal strength.

Check the ZigBee configuration of the master device and repeat
the device discovery/slave detection.

Make sure the home gateway yellow LED (Link) blinks the total
number of slaves including the repeater(s).

Repeat the device discovery/slave detection.
