Redundancy Unit Messages
Redundancy means that a system chassis has more than one of certain critical
components. Fans and power supplies, for example, are so important for
preventing damage or disruption of a computer system that a chassis may
have “extra” fans or power supplies installed. Redundancy allows a second
or nth fan to keep the chassis components at a safe temperature when the
primary fan has failed. Redundancy is normal when the intended number of
critical components are operating. Redundancy is degraded when a
