Removing and Replacing a Cisco ASR 1002 Router Power Supply
Figure 8-32 Cisco ASR 1002 Router Improper AC Power Cord Cabling
Note Using a tie wrap for the AC power cable is optional and not necessary. However, if you do attach
the AC power cable to a power supply tab and then you remove the AC power cable for some
reason, check for any damage to the cable after you cut the tie wrap off. If the power cord is
damaged, replace it immediately.
Step 4 Plug the AC power supply cable into the AC power source.
Note 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.
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.
This completes the procedure for installing the AC power supply in the Cisco ASR 1002 Router.
