The Mean Time between Failures (MTBF) for individual switch components is shown in the

tables below. These figures indicate the mean elapsed time until a single component fails in the

module, whether or not that failure impacts the operation of the switch. Note that in many

cases redundant modules can be configured, which dramatically increases the overall system

Mean Time between Critical Failures (MTBCF).
