NAE flash memory commonly becomes corrupted when an NAE disk image update or archive download is interrupted. To avoid memory corruption and data loss, follow the procedure for disk image updates and archive downloads carefully, and allow the NAE to complete the update and download without interruption.
Update and upgrade related problems may also occur when the SCT software, NAE software, and the NAE archive databases are of incompatible versions. When you update the NAE disk image, you must update the NAE archive database to match the new software version. The SCT application used to configure a Metasys or NAE must also be of the same software version as the NAE software.
Refer to the NAE Update Tool Help (LIT-12011524) and see the Related documentation section of this document for additional information on disk image updates and archive upgrades and downloads.
