Cisco ASR 1002-F Router Overview and Installation
Using a cable tie for the AC power cord is optional and not necessary. However, if you attach the AC power
Note
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.
Four power supplies must be installed in the chassis at all times, with a minimum of two power supplies
Note
(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 4
Plug the AC power supply cable into the AC power source.
What to do next
This completes the procedure for connecting AC input power to the Cisco ASR 1002-F Router.
Connecting DC Input Power to the Cisco ASR 1002-F Router
The DC power supply input connector is a Euro-style type terminal block. A means to provide strain relief
to the input wires is provided on the power supply. The connection order is negative (–), positive (+), and
ground (GND); but this is the order from left to right that the terminals appear on the power supply, not the
order in which the leads should be connected during installation. The order the leads should be connected is
ground (GND), positive (+), and negative (–).
The recommended branch circuit breaker for the Cisco ASR 1002-F Router DC power supply is 30 A. Use
an AWG #10 wire gauge on the 30 A circuit.
The following image shows the DC power supply for the Cisco ASR 1002-F Router.
