The redundant power option provides a second, identical power supply to ensure that power to the
chassis continues uninterrupted if one power supply fails or input power on one line fails.
In systems configured with the redundant power option, connect each of the two power supplies to
a separate input power source. If you fail to do this, your system might be susceptible to total power
failure due to a fault in the external wiring or a tripped circuit breaker.
To prevent a loss of input power, be sure that the total maximum load on each circuit supplying the
power supplies is within the current ratings of the wiring and breakers.
