Issue
A CX9200 running Continuum v1.500030 will not upgrade the node count from 64 to 127.
Environment
CX92000
Xdriver, Webserver
Cause
A CX9200 running Continuum v1.500030 will not upgrade the node count from 64 to 127.
Resolution
CX9200 boards were manufactured before UPD flash files were used to upgrade the options set in EEPROM (like the node count). The CX9200 options are upgraded by loading a serial DMP file (available through Repair) and then resetting the controller.
In this particular case, the controller would appear to accept the dump file with no error, but the node count did not change.
The issue was resolved by upgrading the firmware chips to version 1.52 or later, and then loading the dump file from the Repair Dept.
To avoid paying for a firmware upgrade just to increase the node count, the workaround is:
- Temporarily install v1.52 firmware chips
- Do the upgrade with the DMP file
- Reinstall the old chips
Note: A similar thing is true if looking to add the Webserver option to a CX9200. If you have Continuum v1.52 chips installed, then you can get a dump file from the Repair Department to add the webserver option. If the board is older than v1.52 you will need to send the board into Repair for them to make the change.
