Do not run the AC power cord through the either power supply handles as shown in the following figure.
Caution
Figure 280: Cisco ASR 1002 Router Improper AC Power Cord Cabling
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.
Note
Step 4
Plug the AC power supply cable into the AC power source.
Two power supplies must be installed in the chassis at all times, with a minimum of one power supply connected
to the mains in order to power on the system and 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 must be connected.
Note
If you remove a power supply from a system that are connected and powered on, the system can run only for
a maximum of five minutes before shutting down. However, because the fans and power elements are
independent within the power supply, the replacement power supply does not have to be energized within
five minutes. The only requirement is that the power supply be installed in the chassis in order to energize
the fans and maintain proper system cooling.
Caution
What to Do Next
