Learn how to identify your device's state based on the LED color patterns. These blue and white status LEDs apply to all our UniFi access points, routers, switches, and the UDM base model.
Status LED Patterns
Note: The animations are for illustrative purposes - the speed of the flashing or strobing patterns below might differ slightly from your device's.
Flashing White / Off Every 1/2s
The device is initializing and booting up.
The device is ready for adoption.
Slow Flashing Blue (UDM Only)
A client device is connected to the UDM via Bluetooth.
Blue and Flashing Off Every 5s (UDM Only)
There is no internet connection to the UDM.
The device is adopted and is in normal operating mode. Access Point is broadcasting WiFi.
Strobing White / Off
If this happens, power cycle the Access Point.
If this doesn't help, please reach out to our support team.
Quickly Flashing White / Blue
The device firmware is currently being upgraded - do not interrupt the process.
UDM will flash only white during an upgrade.
Blue and Flashing Off Every 5s
Access Point has lost network connectivity and is searching for a wireless uplink.
Rapid Flashing Blue / Off
The device "Locate" feature was activated in the UniFi Network application.
The device is in TFTP mode.
To enable this mode:
- Hold the reset button before powering on.
- Continue to hold the reset button until this LED sequence appears.
If this wasn't intentional, please ensure the device's reset button isn't jammed (it should click when pushed).
The device is offline.
Verify the Power, POE, and Ethernet cables to troubleshoot.
UniFi Bridge to Bridge (UBB)
Including the statuses described above, the UBB has two additional ones:
Red with Circulating Blue LED
The 60 GHz link cannot be established or has dropped due to bad weather. If the UBB fails over to 5 GHz, the LED will remain red. When the 60 GHz link is re-established, the LED will turn blue (or the custom color selected in the UniFi Network application).
Note: If the other bridge device is within range and the UBB LED is red, we recommend adjusting the UBB's position to enhance the signal strength.
If the Alignment Tool enabled in the UniFi Network application, a green LED means the UBB devices are properly aligned.
Note: If the other bridge device is within range and the UBB LED is green and red, we recommend adjusting the UBB's position until the LED is green.
LED Patterns for Ports
The ports of UniFi Security Gateways and UniFi Switches have a different type, number, and location.
Please refer to your specific device model's Quick Start Guide (QSG) for the exact location and description of its ports.
Console Port's right LED (in the applicable devices):
- LED Off: Power Off
- LED Green: Power On
Speed/Link/Act (right LED ports other than Console):
- LED Off: No Link
- LED Amber: Link Established at 10/100 Mbps
- LED Flashing Amber: Link Activity at 10/100 Mbps
- LED Green: Link Established at 1000 Mbps
- LED Flashing Green: Link Activity at 1000 Mbps
PoE (left LED on ports of applicable devices):
- LED Off: No PoE
- LED Amber: IEEE 802.3af/802.3at
- LED Green: 24V Passive
SFP (in the applicable devices):
- LED Off: No Link
- LED Green: Link Established at 1 Gbps
- LED Flashing Green: Link activity at 1 Gbps
See specific port LED information in the Hardware Overview section (between pages 5 and 6) of the Quick Start Guides (QSG). You can find the QSGs in the Documentation section of our UniFi Downloads page, by searching for the device in question in the left-hand menu.
LED Patterns for PoE Adapters
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 may indicate that the device is not connected properly, or that something is wrong with the cable.
How to Disable Device LEDs
The device status LEDs can be disabled for all the site, or only for specific UniFi devices.
To enable/disable status LEDs throughout a site, go to to Settings > Site on the UniFi Network application and edit the LED feature in the Services section.
To configure specific devices individually:
- Go to the Devices section and click on the device you wish to edit to bring up the Properties panel
- Go to Config > General > LED and switch the Site Settings to On or Off.
