Upgrading the version of firmware running on a CPUM card
CONFIGURATION OF CPUM / IOCN CARDS
13.10Upgrading the version of firmware running on a CPUM card
Earlier versions of the CPUM card use a DiskOnChip DIP memory module for the storage of
the firmware (FW) and user-editable configuration files used by the CPUM. As DiskOnChip
memory modules are no longer produced (end-of-life), these CPUM cards need to be
upgraded to use a CompactFlash memory card instead of the DiskOnChip memory in order
to allow the CPUM to run more up-to-date versions of firmware.
Refer to the CPUM upgrade kit instruction sheet (document reference 268-037) for further
information on replacing a CPUM card’s existing memory with a newer CompactFlash
memory in order to upgrade the CPUM card to run a different version of firmware.
NOTE: The CPUM upgrade kit instructions are equally applicable to versions of the CPUM
card already using a CompactFlash memory card, except that the new
CompactFlash included in the upgrade kit replaces the existing CompactFlash on
the CPUM (rather than replaces the DiskOnChip).
