AP121 will not boot - displaying error - bad magic number 0xffffffff when connected via console.

Factory reset doesn't seem to work.
Any ideas? or is this device 'bricked'

Thanks in advance.

Yep, this is corrupted firmware and you'll need to see if Tech Support can assist in recovering or id they'll have to issue an RMA.

You can try to reload the firmware. This is probably what support will have you try first.
  1. While connected to the console, power on the AP and stop the boot process (hit the "space bar" before the autoboot process starts)
  2. At the password prompt type in administrator
  3. At the next prompt type set_bootparam
  4. Change each of the boot parameters to meet your environment. Pressing "enter" will accept the displayed default.
  5. Device IP: [] is DHCP. Enter an IP address if you don't want to use DHCP.
  6. TFTP Server IP: [] is the IP address of your TFTP server. Enter the IP address of your TFTP server here.
  7. VLAN ID: [0] is the management VLAN ID. Only change this if you know the traffic needs to be tagged.
  8. NVLAN ID: [0] is the default/native VLAN ID. Same as above.
  9. Boot File: [] is the name of the image file. So if we were using the current version as of this post, you would enter AP141-6.5r4.img.S. But you can use whatever version you are currently using.
  10. Netboot... don't need to change.
  11. Netdump... don't need to change.
  12. Are you sure to save? [Y/N] type Y to save changes or N if you messed something up and don't want to save changes.
  13. Now back at the prompt type image_flash and wait for it to finish downloading and installing the firmware.
  14. Once it finishes, type reset to reboot the AP
If it still can't boot, you will probably need to RMA the AP.
