Table 1-2 SAU LED Indicators
LED Status Description
AL (Alarm) Off The diagnostic test has passed and the ODU is operating
normally.
On Red An ODU failure has been detected.
PW (Power) Off The ODU is not receiving power or there is an internal
3.3 VDC failure.
On Green The SAU is receiving power from the ODU.
ET (Ethernet) Off There is no valid Ethernet link between the ODU and the
IDU.
On Green There is a valid Ethernet link between the ODU and the
IDU.
WLNK
(Wireless link)
Off The ODU is not connected to a base station.
On Orange The ODU is connected to and receives services from a
base station (Network Entry completed). Link quality is
indicated by LEDs 1-9, as described below.
Blinking Orange Authentication has failed due to one of the following
reasons (indicated by the WiMAX Link LEDs):
•
If LEDs 6, 7 and 8 are on: Authentication has been
rejected by the RADIUS server.
• If LEDS 7 and 8 are on: Authentication has been
rejected by the base station (due to a duplicate
subscriber unit name in its database).
• If LED 8 is on: Authentication has failed due to a
timeout, or there was a re-authentication failure
(connection to the RADIUS server was lost or a
mismatched shared secret).
