A Standby gate behaves just like a standby container in BlockSim's RBDs. Standby containers were discussed in [[Time-Dependent_System_Reliability_(Analytical)|Time-Dependent System Reliability (Analytical)]] and [[RBDs_and_Analytical_System_Reliability|RBDs and Analytical System Reliability]]. Events leading into a Standby gate have active and quiescent failure distributions, just like contained blocks. Furthermore, the gate acts as the switch, can fail and can also define the number of active blocks whose failure would cause system failure (i.e., the Active Vote Number required ). In BlockSim, no additional gates are allowed below a Standby gate.

====Example====
Consider a system with two units, ''A'' and ''B'', in a standby configuration. Unit <math>A</math> is active and unit ''B'' is in a "warm" standby configuration. Furthermore, assume perfect switching (i.e., the switch cannot fail and the switch occurs instantly). Units ''A'' and ''B'' have the following failure properties:

*Block <math>A</math> (Active):
::*Failure Distribution: Weibull; <math>\beta = 1.5\,\!</math>; <math>\eta = 1,000\,\!</math> hours.
*Block <math>B</math> (Standby):
::*Energized failure distribution: Weibull; <math>\beta =1.5\,\!</math>; <math>\eta = 1,000\,\!</math> hours.
::*Quiescent failure distribution: Weibull; <math>\beta =1.5\,\!</math>; <math>\eta = 2,000\,\!</math> hours.

Determine the reliability of the system for 500 hours.

'''Solution'''

The fault tree diagram for this configuration is shown next and <math>R(t=500)=94.26%\,\!</math> .
