Note Remember to enter quotation marks before and after the
boot software filename. The filename you use depends on
the release to which you are upgrading. For more
information, refer to the Release Notes for Cisco MGX

upgrade will not complete, the card will not operate,
and the card must be returned to Cisco for repair.
