Reliability (MTBF)

The Mean Time between Failures (MTBF) for individual switch components is shown in the
following tables. 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).
MTBF per 4700 model types:

Model A: The system configuration is a fully populated chassis with 18 line cards, 9 fabric
cards, 3 power supplies, 1 Management Board and 2 fan modules (Horizontal and Vertical
drawers).

Model B: The system configuration is a fully populated chassis with 18 line cards, 9 double
fabric cards, 4 power supplies, 1 Management Board and 2 fan modules (Horizontal and
Vertical drawers).
