Hardware reliability
This section provides information about the reliability of the Avaya Secure Router 2330/4134
hardware. This section uses the following terms:
• failures in time (FIT)—The number of failures for each billion (10
9
) accumulated device
hours.
• mean time between failures (MTBF)—The average value of the time intervals between
successive outages of the system. This average value is calculated from, and based on,
a large population of nominally identical items.
The following table provides information for the expected reliability of Secure Router 4134
hardware in terms of FIT and MTBF.
Important:
Ensure you install the Secure Router 2330/4134 and its components correctly and operate
the unit within the intended environment under specified conditions. The failure rate and
MTBF values in the following table do not include failure caused by software or erroneous
human action.
