Products Affected
Products Affected ASR1013/06-PWR-AC ASR1013/06-PWR-DC
Problem Description
A defect has been identified in a subset of the ASR1013/06-AC(=) and ASR1013/06-DC(=) power supplies that can result in intermittent failure of a power supply unit.
Background
Power supplies ASR1013/06-PWR-AC(=) and ASR1013/06-PWR-DC(=) shipped from June/2011to June/2012 may fail overtime due to a corrosion on the board-to-board connector.
ASR1000 product family has redundant power supplies, so the system will not have a functional failure until two power supply units within the same zone fail. Show commands, syslog messages and SNMP traps are available to detect failures of individual power supply units so that they may be replaced in a timely manner to prevent system down situation.
Note 1:
ASR1k Power Supply is a redundant system with integrated fans. The router will be fully functional if one of the P/S fails. However, the power supply is required to be plugged in for the integrated fans to provide cooling for the system.
Problem Symptoms
The end-user will see one or more of the power supplies in the system intermittently cycling off and on. The problem may take many months to develop after the system has been installed and is operational.
Customer can do the following to confirm that the PS is off or has failed:
1. Check that the PS switch is turned on
2. Check that the PS Vin is in the expected range (121V AC in the example below)
3. Check the PS Vout value

Workaround/Solution
Cisco recommends replacing the suspect ASR1013/06-PWR-AC(=) and ASR1013/06-PWR-DC(=) by filling information in Upgrade form at the end of this notice.
Cisco has taken corrective actions and implemented the necessary changes to correct the problem on ASR1013/06-AC(=) and ASR1013/06-DC(=) power supplies shipped after June/2012.
