Solution
When attempting to copy the controller firmware/code to the controller flash using ftp/tftp it will not extract to the flash, it will be saved in /opt/meru/images/ directory as a tar file, it will not untar.

STEPS TAKEN FOR TROUBLESHOOTING:

STEP 1 :	Verify if the controller firmware that is downloaded is intended for the respective controller.
STEP 2 :	Try copying the file using ftp/tftp using the below command :
	# copy ftp://username@ip_address_ftp_server/<image-name>.tar. (where username is username of ftp server and ip address is ip address of ftp server and make sure that there is space after filename.tar and ends up with “.” “fullstop/period”) # copy tftp://ip_address_tftp_server/<image-name>.tar . (where ip address is ip address of tftp server and make sure that there is space after filename.tar and ends up with “.” “fullstop/period”)
STEP 3:	Type “show flash” command and see if the file/code is extracted. Command to be used #show flash
STEP 4:	If still the code is not found using the above command execute the below command and see if the file is located in the “images” directory, command to be used : #cd images #dir #file_name.tar
STEP 5:	If you're still not able to extract the file, log into root and execute the following commands for example: # show flash 3.6-130 #log root bash-2.05a# cd /opt/meru/images/ bash-2.05a# ftp 10.10.58.27 (note the ip provided is ip address of the ftp server) Connected to 10.10.58.27 (10.10.58.27). 220 3Com 3CDaemon FTP Server Version 2.0 Name (10.10.58.27:admin): anonymous 331 User name ok, need password Password: 230-The response '' is not valid. 230-Next time, please use your email address as password. 230 User logged in Remote system type is UNIX.

STEP 6:	Now extract the tar file (controller code) using the following command (example) bash-2.05a# tar -xvf meru-3.6-127-MC1000-rpm.tar bash-2.05a#exit MeruController1# show flash 3.6-130 3.6-127 (Now the code 3.6-127 is found in flash)
RESOLUTION:	The code can be uploaded to the controller flash using the above steps
