Removing and Replacing the Cisco ASR 1013 Router Power Supplies
Step 3
Turn the power supply standby switch to the Standby position. See
Figure 14-69

Step 4
Unplug the power cable from the AC inlet on the back of the power supply and the power source.
Step 5
Unscrew the power supply captive screws.
Note
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.
Caution
If you remove a power supply, the system can run for a maximum of five minutes before the system shuts
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.
Step 6
Grasping the power supply handles, pull the power supply from the chassis.

.
Note: Shielded cables must be used to connect to the DB-25 alarm connector on both the AC and DC power supplies, in order
to comply with FCC/EN55022/CISPR22 Class A emissions requirements.
