Redundancy Status |
Redundancy Status can be Full or Lost.
Currently, all systems have n+1 power supplies, where n
is the number of power supplies that are required for the system to
work under fully loaded and stress conditions. If the number of power
supplies in a system that is required for full redundancy is
three:
Redundancy status is Full when three power supplies
are working.
Redundancy Status is Lost with a status of
Noncritical when two power supplies are working.
Redundancy Status is Lost with a status of
Critical when only one power supply is working.
Full redundancy is defined by system specification.
Lost redundancy means that there are no backup power
supplies available to take over for the minimum number required, but
at least one power supply is working.

Number of Devices Required for Full Redundancy | Your system has a number of power supplies defined for full redundancy. Currently, all systems have n+1 power supplies, where n is the number of power supplies that are required for the system to work under fully loaded and stress conditions. If the number of power supplies required for Full redundancy is three, redundancy is lost when one or two power supplies are working. |
