Warning
When removing the unit, the ground connection must always be made first and disconnected last.
Step 6
Loosen the four captive screws on the DC power supply.
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.
Caution
If you remove a power supply from a system that has four power supplies 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.
Step 7
Grasping the power supply handles, pull the power supply from the chassis.
Step 8
Replace the DC power supply within five minutes.
This completes the procedure of removing a DC power supply from the Cisco ASR 1013 Router.
