I am experiencing an issue where i am unable to connect an AP to a ZD. It appears that the issue is because the FW downloaded has an error 'bad cksum' (please see below). Is there anyway i can overwrite this or delete it?
Do you have access to AP CLI or GUI? If not, you need RMA. If you have access to GUI, you can install AP image from local PC. If you have only CLI, you can install AP image from tftp server by the following steps.
fw set proto tftp fw set host fw set control fw update
You can download AP standalone image from Ruckus Support.
There isn't a way to delete the file from the AP command-line. But when you re-try the connection, the AP will try to download the firmware again. If it is continually corrupt after download, there could be another issue, whether that is on the AP itself, in the firmware image, or the network.
You could try a manual transfer of the file using TFTPD32 or Filezilla FTP server and see if you ahve more success. Commands on the AP are:
You can download a copy of the 7363 firmware by enabling FTP on the ZD, presuming your networks' security policies allow this
a. enable FTP on ZD: en conf sys ftp-anon
b. Open a web browser to ftp://x.x.x.x (IP of your ZD) c. Login, browse to the directory 'zf7363' and download a copy of the firmware. d. Put the newly downloaded firmware in your TFTP root directory. If you can, run checksum on it.
Now that you have the file on your own TFTP server and know the checksum, SSH to the AP and try to download it from your TFTP server:
fw set proto tftp fw set host x.x.x.x (IP address of your TFTP server) fw set control fw update reboot
After this, the AP will boot-up and hopefully take load the AP firmware.
If problems persist, I'd recommend logging a case with Support and providing the APs support-log. You can get this by:
1. Recreating the problem 2. SSH into the AP 3. Type 'support' 4. Type 'support show' and save the output into a txt file.
