Firmware Compatibility
Firmware 3.4.0 is compatible with all currently existing hardware
versions of CBS. However, some CBS hardware/firmware
combinations are not supported due to compatibility issues. Following
is a summary of these restrictions:
7730 CBS Hardware Release CBS Identification Compatible Firmware
3.0
3.1
Serial number less than
31-36497717
All versions
“original” 3.2 Serial number greater
than or equal to 31-
36407717 and service part
number less than 497-
0435814
3.2.0 and higher
“revised” 3.2 Service part number
greater than or equal to
497-0435814
3.4.0 and higher
Note: An exact serial number break-in point for the revised CBS
hardware release 3.2 will be available at a future date.
Firmware Downgradability
Once a CBS is installed with firmware 3.2.0 or higher, it cannot be
downgraded below firmware 3.2.0 except by returning it to the factory
or by contacting NCR Level 4 support for special assistance. This is
true regardless of the CBS hardware release. The ftpdl.exe utility
reports an error and the CBS remains unaffected if downgrade is
attempted. Note that firmware 3.2.0 does not support the TFTP
bootloader feature.
