Defect Information

Defect ID	Headline
CSCwb41132	Codec Pro, improved internal heat control

Problem Description

Inadequate cooling can cause the power supply in the Codec Pro to overheat and fail, which results in unrecoverable failure of the device.

Background

A number of factors can cause the power supply to overheat, such as installation location, air temperature, and air flow rate.

Problem Symptom

The device might unexpectedly shut down and become unresponsive.

Workaround/Solution

If the device is operational, install software Version 10.11.5.2 or later, which increases the power supply fan speed in order to improve internal cooling. If the device has already failed, follow the normal Return Material Authorization (RMA) process as per your service agreement or warranty terms, as there is no workaround once the failure has occurred.
