AP-7131 stuck booting?

yanntllr — Mon, 09 Aug 2021 22:44:23 GMT

I bought a Motorola/Symbol AP-7131 that when plugged in will get stuck at blinking LED1 red (booting if my reading of the manual is right) and LED 5 is solid green (2.4GHz configured), i tried letting it plugged in for 24 hours and it stays there, i also tried reading any serial output but there is nothing, or it is at a different speed than what the manual states. i am kinda lost at what i may be doing wrong or if the AP is just dead.

can anyone help?

thanks

Try these settings for serial consoler port; but if you still do not see any output than AP is most likely bad,

How to use the serial console port on WiNG Devices?

Thank you very much, with those settings (115200 instead of the 19200 the manual states) i got an output, makes little sense to me though:

“�f62f�” or in hex 9F 66 36 32 66 E7 00 0E

sorry but i would need a bit more help in confirming if this thing is dead or if it is a problem with my setup

First thing you have to check is power. This unit uses 802.3AT and not 802.3AF power. is it receiving the correct power?

Thank you,

i am not using PoE, i power my unit with its power supply (Motorola PWRS-14000-247R), it properly reads 48V even with the AP plugged in, but yeah power was a good idea i did not think about, thanks.

can you share what you are seeing after you reboot the AP?

might have just been a fluke, tried again 3 times and twice got nothing and the last one got a space at 115200 and get a bunch of 0x00 at 19200, i feel like i am getting random garbage… i was kinda hoping that it was something stupid as it seemed to init correctly. although it makes little sense that the LEDs would act as they should if the cpu just was throwing random data on its output, but then i have no clues on the architecture of an AP, especially this one.

and as i have not seen any button to reboot i just unplug and replug it again, hope this is not the problem

Seams like this AP is BAD. The below is from the CLI user guide of the AP. If your not getting any human readable context than its safe to say it is a BAD AP.

Accessing the CLI through the Serial Port To connect to the access point CLI through the serial port:

1. Connect one end of a null modem serial cable to the access point’s serial connector.

2. Attach the other end of the null modem serial cable to the serial port of a PC running HyperTerminal or a similar emulation program.

3. Set the HyperTerminal program to use 19200 baud, 8 data bits, 1 stop bit, no parity, no flow control, and auto-detect for terminal emulation.

4. Press or to enter into the CLI.

5. Enter the default username of admin and the default password of motorola. If this is your first time logging into the access point, you are unable to access any of the access point’s commands until the country code is set. A new password will also need to be created.
