Cisco ASR 1002 Hardware Installation Guide

Step 3
Turn off the branch circuit breaker before touching terminal screws. Then start loosening the terminal block screws to
remove wires.
Step 4
Remove the leads from the terminal block in the following order.
a) Negative lead
b) Positive lead
c) Ground lead
Step 5
Unscrew all of the power supply captive screws.
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
Step 6
Grasping the power supply handles, pull the power supply from the chassis.
Step 7
Replace the –48 VDC power supply within five minutes.
What to Do Next
This completes the procedure of removing a –48 VDC power supply from the Cisco ASR 1002 Router.
Replacing the –48 VDC Power Supply in Cisco ASR 1002 Router
The –48 VDC power supply input connector is a Euro-style terminal block. Features are provide for strain
relieving the input wires from the terminal block on the front panel. The ground wire must contain a loop
when secured to prevent any strain on the wires. The connection order is negative (–), positive (+), and GND.
The recommended branch circuit breaker for the Cisco ASR 1002 Router –48 VDC power supply is 30 A.
Use an AWG #10 gauge wire on the 30 A circuit.
This section describes how to connect the –48 VDC power supply in the Cisco ASR 1002 Router.
The color coding of the –48 VDC input power supply leads depends on the color coding of the –48 VDC
power source at your site. Typically, green or green/yellow is used for ground. Make certain the lead color
coding you choose for the –48 VDC input power supply matches lead color coding used at the –48 VDC
power source.
Note
When you install the unit, the ground connection must always be made first and disconnected last. Statement
