Air AP 1832 flashes red and no usable output on serial console

[gotthardanger]

Hi,

Suddenly one of our 1832 stops working. In serial console I get repeatetly output like this

GPVTG,,T,,M,,N,,K,N*2C
$GPGSA,A,1,,,,,,,,,,,,,,,*1E
$GPGGA,,,,,,0,,,,,,,,*66
$GPRMC,,V,,,,,,,,,,N*53
$GPGSV,3,1,12,01,08,240,,03,45,135,,04,62,240,,06,26,239,*7E
$GPGSV,3,2,12,07,05,340,,08,46,102,,09,,,,11,66,262,*48
$GPGSV,3,3,12,13,02,060,,15,,,,16,46,175,,17,20,284,*44
$GPVTG,,T,,M,,N,,K,N*2C
$GPGSA,A,1,,,,,,,,,,,,,,,*1E
$GPGGA,,,,,,0,,,,,,,,*66
$GPRMC,,V,,,,,,,,,,N*53

poe status on switch remains on 1%, link goes to off

led is fast flashing between amber, red and green (end state after approx. 5 minutes)

Is there any chance to get a normal prompt on console?

Thx in advance

@gotthardanger normally, when AP flashing all colours that means its trying to find a controller. is this controller based? try changing your baud rate to 9600 in console settings.

[gotthardanger]

yes, it´s controller based. I´m wondering because the ap disconnects from switch (ap doesn´t show up in mac address table of the switch)

changing serial connection to 9600 has no effects

[gotthardanger]

additional information: I tried some factory rest procedures (mode button - wait until led shows red or amber - release)

the console output doesn´t change. I have to assume the boot code is damaged

@gotthardanger in that situation, its better to contact TAC and try to resolve issue.,

RMA the AP. 

1800 are well known to have (high) failure rates.
