CSS 11503 and CSS 11506 units shipped between August 6, 2002, and September 3, 2002, were shipped with 5.19 build 100. Software version 5.19 build 100 is beta code and it should have been removed before shipping.
Execute the version command from the command line interface of any of the CSS units to determine which version of software is running on them. An upgrade is necessary if 5.19 build 100 is running on any CSS.
There are two solutions for this issue, both of which require a software change.
The solution in 5.10 software requires that the operational flash be refreshed to the 5.10 level. The following commands must be executed from debug mode to refresh the operational flash. You can get into debug mode by hitting ESC-X.
xmask sysflash set misc 1 1 0x2 xmask sysflash set misc 2 1 0x2 xmask sysflash set misc 3 1 0x2
xmask sysflash set misc 1 1 0x2 xmask sysflash set misc 2 1 0x2 xmask sysflash set misc 3 1 0x2 xmask sysflash set misc 4 1 0x2 xmask sysflash set misc 5 1 0x2 xmask sysflash set misc 6 1 0x2
Then follow the upgrade procedure seen at Upgrading Your CSS Software.
No commands need to be executed before the upgrade to 5.20 software. The operational flash will be upgraded automatically since 5.20 software is more recent than 5.19 software.
Follow the upgrade procedure seen at Upgrading Your CSS Software. The 5.20 software will be available on October 1, 2002.
