I try to install the k9 image to a Cat4500x without success. The image has been uploaded using tftp, boot variable set to the new image and config register set to 0x2102. The device hangs in rommon with the following message:
rommon 3 >boot bootflash:cat4500e-universalk9.SPA.03.05.02.E.152-1.E2.bin
Loading image !!!!!!!!!!!!!!!!!!!!!!
Checking digital signature....
Verification FAILED for bootflash:/cat4500e-universalk9.SPA.03.05.02.E.152-1.E2.bin, REASON: RSA signature verification failure
Even after uploading the binary again and check md5 checksum I got the same error message.
Could someone give me a hint what I am doing wrong? Is there another procedure to convert the switch from universal to universalk9?
Many Thank!
Kind Regards,
Urs
