Configuration Guide System Upgrade Configuration
The displayed main program version indicates the version number of main program
being run in the system. Therefore, in the case of manual installation, the displayed
version number of main program is not the version number of software newly
installed, but the version number of software run currently.
When using "show version" command to show the version number of
image with version older than 10.4(2), the system cannot display the
release version marking of this image. The release version marking
indicates the release time of this image, and is shown in the brackets
after the version number. For example, in the version number of
10.4(2), "2" is the release version marking.
Common Upgrade Problems
Loss of Main Program of Master Management Board
The user may accidentally delete the boot/main program of the file system, and the
system will give the following warning information:
Warning: System boot file rgos.bin is missing.
However, if the user doesn't notice such loss of main program and dynamically
inserts a new line card during the subsequent use, the system will prompt:
*Aug 25 13:21:50: %UPGRADE-3-DISPATCH_FAIL: Dispatch program to slot 3
failed.
The aforementioned prompt and function are only supported by
products running 10.4(2) or higher version.
Unsupported Line cards
If the line card detected be device is not supported by the current software version,
the system will prompt:
*Jan 2 00:00:39: %UPGRADE-4-CARDNOTSUPPORT: The linecard in slot [dec/dec/...]
is not supportted by current version.
In such a case, support to such type of line card as specified in the release of current
software version shall be verified. If this line card needs to be supported, then the
current software shall be upgraded.
