TB8100 Service Kit User’s Manual Working with Different Versions 57
Working with Different Versions
As time goes by, it is natural to end up with a system that has a mixture of
versions. For example:
Q A module fails and its replacement has a newer hardware version.
Q New firmware offers a highly desirable feature so a module is upgraded.
Q A new Service Kit version is released and is loaded on the PC.
When modules with different versions try to work together, compatibility
problems can arise. The following offers some guidance.
Quick Tips Q A PC can only have one Service Kit version installed at a time. Ensure that
upgrading the Service Kit does not make it incompatible with your base
station equipment.
Q A new Service Kit can only save a configuration in its own format, but it
can program the information into an older base station.
Q Version numbers are incremented when an update is made. Versions that are
designed to work with each other don't necessarily have the same version
number.
Q For information about compatibility for particular versions, see the Release
Notes (on the Product CD).
Replacing
Modules
When replacing a PA, PMU, or reciter module, check the Release Notes to
ensure that the module is compatible with the other modules in the subrack.
(Hardware versions are on the module label. The Service Kit can display
firmware versions).
Upgrading
Firmware
You can use the Service Kit to upgrade the firmware of a base station module.
The Service Kit will only let you select firmware versions that are compatible
with each other and with the respective module's hardware version.
Upgrading the
Service Kit
Before installing a version of the Service Kit from the product CD, check the
compatibility table in the Release Notes to make sure that the Service Kit will
be compatible with the base station modules' firmware and hardware versions.
