Appendix A: Hardware reliability

This section provides information about the hardware reliability of the switch, and hardware
components.
Mean time between failures
Mean time between failures (MTBF) is the average value of the time intervals between successive
outages of the system. This average value is calculated from a large population of nominally
identical items. The following table provides MTBF values for VSP 7000 Series hardware.
Important:
You must install the switch and its components correctly and operate the hardware within the
supported environmental conditions. The MTBF values in the following table do not include
failure caused by software or human error.
