46. After the slot 4 NMIC reboots, a database restoration window will appear on the Cellworx
GUI screen from the slot 2 NMIC.
Note: It is imperative that the user selects the slot 2 NMIC for database restoration
because only the database files on this NMIC were converted from release 3.0 format to
release 3.1 format.
Warning: Following the software upgrade procedure, there are several actions that could
invalidate software fallback. The user SHOULD NOT perform any of the following
tasks unless he is certain that a software fallback from release 3.1 to release 3.0 is not
necessary.
• Make any topology modifications (add/remove NE, all shelf types)
• Remove any existing cards
• Delete any existing connections
• Change the time of day clock
• Perform a ring upgrade (OC3c --> OC12c, etc.)
• Remove any file in the /cellworx/config directory with the extension,
".release3.0". These files must be present in order to perform a software
fallback.
Also be aware of the following restrictions:
• If a release 3.1 card is installed in a shelf (such as OC12c CRS), remove that
card before performing software fallback.
• Delete any connections that are created following software upgrade before
attempting software fallback.
