Access Points, Security Gateways, Switches and Cloud Keys

Starting with Gen2 UAPs, we moved on to the Blue and White LED. USGs, UniFi Switches and Cloud Keys also use the same Blue and White LED patterns showcased in the table below, and they will mean the same thing. Legacy UAPs will have an Amber and Green LED on the front of the unit as seen in the
Legacy section. Some products don't feature status LED patterns, such as the
PoE Adapters.

The LED of the PoE Adapters are simple to interpret:
LED is Off - PoE is Off
LED is On and steady - PoE is functioning as it should
LED is blinking - this is not a configured state, this just might mean the device is not connected properly, or that something is wrong with the cable.
