LEDs
Signal The first LED is lit red when the
wireless signal strength is above -94 dBm,
and the second LED is lit amber when the
wireless signal strength is above -80dBm.
The third LED is lit green when the wireless
signal strength is above -73 dBm, and the
fourth LED is lit green when the wireless
signal strength is above -65 dBm.
Ethernet The Ethernet LED is steady green
when an active Ethernet connection is made
and flashes when there is activity.
Power The Power LED is steady green
when the NanoBridge is connected to a
powersource.
Note: In airOS, you can modify the threshold values for each
LED on the Advanced tab under Signal LED Thresholds.
Installation Requirements
• 13 mm or ½" wrench
• Shielded Category 5 (or above) cabling should be used for all
wired Ethernet connections and should be grounded through
the AC ground of the PoE.
We recommend that you protect your networks from the
most brutal environments and devastating ESD attacks
with industrial-grade shielded Ethernet cable from Ubiquiti
Networks. For more details, visit www.ubnt.com/toughcable
