I have no power adapter for it, we currently use it with a poe switch, which is serving production APs at the moment.
Also, I just noticed you have the "enable" command on that list. Can you enter that command then list what available commands you have.

when I do enable it asks me for the password which I then supply but doesn't change the available commands like on a normal IOS router

ok, your first suggested solution worked until a certain point. it wouldn't find the file on the tftp server, even tho I matched the file name and extension to the exact thing the log said. so while trying to resolve that I found this other article which allowed me to do the process manually:

You need to perform these steps:

Restart the Access Point
While it loads the image in flash, press Escape, you’ll enter ROMMON mode:
The system boot has been aborted. The following

commands will finish loading the operating system
software:

 
ether_init

tftp_init

boot

 
Set the IP address for the gigabit 0 interface:
ap: set IP_ADDR 10.0.0.1

ap: set netmask 255.255.255.0

 
Initialize the tftp, ethernet and flash subsystems:
ap: tftp_init

tftp_init success: You can now use tftp file system!

ap: ether_init

Initializing ethernet port 0...

Ethernet speed is 100 Mb - FULL Duplex

ap: flash_init

Initializing Flash...

...The flash is already initialized.

 
Load the image from TFTP and extract it to flash:
ap: tar -xtract tftp://10.0.0.100/ap3g2-k9w7-tar.152-2.JB.tar flash:

 
After it’s done, set the correct bootimage:
ap: set BOOT flash://ap3g2-k9w7-mx.152-2.JB/ap3g2-k9w7-xx.152-2.JB

Boot the system:
ap: boot


after this It became an autonomous device and now im able to manage it.

thank you for your help
