Ambient Temperature and Humidity Requirements for the Cisco SCE 8000
The redundant power configuration 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.
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 because of 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.
In some systems, you might use an uninterruptible power supply (UPS) to protect against power
failures at your site. Avoid UPS types that use ferroresonant technology. These UPS types can
become unstable with systems like the Cisco SCE8000, which can have substantial current draw
fluctuations because of bursty data traffic patterns.
