down. The fans and power elements are independent within the power supply. Therefore, it is not
required that the replacement power supply be energized within five minutes. The only requirement is
that the power supply be installed in the chassis, which energizes the fans and maintains proper system
cooling.

The Cisco ASR 1013 router has two power zones, each containing two power supplies for a
redundant system. Power supplies must be installed in the chassis at all times to ensure sufficient
cooling. The system fans are inside the power supply units and must spin for cooling. Because
all the system fans can be powered by one power supply, the second power supply unit does not
have to be powered on, but it must be installed.
