5508 wlc update problem

[flokki123]

hi,

one of our customers wants to update the firmware of a 5508 wlc, but always gets the following error message:

Error Message   %UPDATE-3-INV_FILE_SIGN: Error! Invalid image signature!. Image may be corrupt.

but the same image works fine on another 5508.

any ideas? the update was downloaded via a smartnet for the wlc, on which the update works fine. does the customer has to download another image for the second controller, or should the image work on both wlc?

thanks for any help!

opened another thread for this question in the english area.
