Name Description Functionality
W-LINK Wireless Link Indicator
 Green - Unit is associated with an AU, no wireless
link activity
 Blinking Green - Data received or transmitted on
the wireless link. Blinking rate is proportional to
wireless traffic rate
 Off - Wireless link is disabled
Status Self-test and power
Indicator
 Green - Power is available and self-test passed.
 Blinking Amber - Testing (not ready for operation)
 Red - Self-test failed - fatal error
ETH Ethernet activity/
connectivity Indicator
 Green - Ethernet link between the indoor and
outdoor units is detected, no activity
 Blinking Green - Ethernet connectivity is OK, with
traffic on the port. Blinking rate proportional to
traffic rate.
 Red - No Ethernet connectivity between the indoor
and outdoor units.
SNR BAR Received signal
strength Indication (In
Normal Mode)
 Red LED: Signal is too low (SNR < 4 dB)
 8 green LEDs: Quality of the received signal
 Orange LED: Signal is too high (SNR > 50 dB)
