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.

The 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 in order to prevent a system down situation.

Note: The ASR1000 power supply is a redundant system with integrated fans. The router will be fully functional if one of the power supplies fails. However, the power supply is required to be plugged in for the integrated fans in order to provide cooling for the system.

Problem Symptom

The end-user will see one or more of the power supplies in the system intermittently cycling off and on. The problem might take many months to develop after the system has been installed and is operational.

The customer can complete these steps in order to confirm that the power supply is off or has failed:

1. Check that the power supply switch is turned on.
2. Check that the power supply Vin is in the expected range (121V AC in the example).
3. Check the power supply Vout value.
