Figure 140: Incorrect Cabling on the Cisco ASR 1002-F Router AC Power Supplies
Using a cable tie for the AC power cord is optional and not necessary. However, if you attach the AC power
cord to a power supply tab and then remove the AC power cord for some reason, check for any damage to
the cable after you cut off the cable tie. If the AC power cord is damaged, replace it immediately. Note
Four power supplies must be installed in the chassis at all times, with a minimum of two power supplies
(one per zone) 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.
