Do you have 2 or more R300 and this one unit is behaving differently?
Here is the link to AP 100.1 firmware User Guide:
https://support.ruckuswireless.com/documents/671-indoor-access-point-100-1-0-0-194-user-guide R300 LED status meanings are on page 53.
Power = Green means your AP is up.
No lights on 2.4G or 5G LEDs means the service is down. Do you have WLANs defined for both bands?
If you do, the LEDs should be Amber, and when clients are connected they'll be Green.
I hope this is helpful.
