Defect Information

Problem Description

The Cisco Digital Content Manager (DCM) Series D9902 might fail to boot up or remain in an endless reboot cycle.

• After a warm reboot command, it takes longer than 15 minutes for the D9902 GUI to become responsive.
• After a power cycle, the fans do not revert to a lower speed within 30 seconds.

If unit is in normal operation, there is very low likelihood this problem will occur.

Background

D9902 might not reboot due to oscillation of one 5V DC DC converter on the main board of the D9902 chassis.

The root cause of the problem is a capacitor value in the stability feedback loop that is not dimensioned with enough safety margin, resulting in possible oscillations on 5V reactive load dependent.

Problem Symptom

The Cisco DCM Series D9902 Digital Content Manager might fail to boot up or remain in an endless reboot cycle. These are common symptoms of the failure:

• After a warm reboot command, it takes longer than 15 minutes for the D9902 GUI to become responsive.
• After a power cycle the fans do not revert to a lower speed within 30 seconds.

If the unit is in normal operation, there is a very low likelihood that this problem will occur.
