Replace a Power Supply in the Cisco ASR 1002 Router
This section provides instructions for removing and replacing the AC power supply and the DC power supply in a Cisco
ASR 1002 Router. Before you begin, make certain the chassis is grounded. Two 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.
If a power supply is removed, the system can run with only one power supply for a maximum of five minutes. The router waits
five minutes before shutting down. This five-minute window allows time to replace a failed power supply.

the power supply units and must spin for cooling. Because all the system fans can be powered by one power supply, the

If you remove a power supply, the system can run for a maximum of five minutes before the system shuts down.
Caution
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.
