A handy reference from the Aerohive team to the Aerohive wireless status LED color codes that indicate what the Aerohive unit is up to:
Blue – HiveAP is booting
Green – IP obtained via ethernet and may be securely connected to HiveManager
Yellow – IP obtained via Wireless Mesh and may be securely connected to HiveManager
White – HiveAP is managed by HiveManager and the configuration or OS Update has been applied.
Purple – HiveAP HiveOS software image is being updated.
Under normal operating conditions you would expect the status LED of the unit to be white, indicating a successful connection to the HiveManager.
