Removing and Replacing the Cisco ASR 1002 Router Power Supplies
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 6
Grasping the power supply handles, pull the power supply from the chassis.
Step 7
Replace the –48 VDC power supply within five minutes.
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.
Note
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.
Warning
When you install the unit, the ground connection must always be made first and disconnected last.
Statement 1046
Step 1
At the rear of the router, check that the power Standby switch is in the Standby position.
Step 2
Ensure that the positive and negative leads are disconnected from the site power source and the source
circuit breaker is turned off.
Step 3
Using a wire stripper, strip approximately 0.55 inch (14 mm) from the negative, positive, and ground
leads.
