Problem Description

In an internal quality inspection, Cisco determined that a limited number of TelePresence Digital Natural Audio Module III (DNAM-III) units might include incorrect wire routing. Over time and in rare cases this issue has the potential to result in a short circuit. Because the Last Date of Support for the TelePresence Digital Natural Audio Module III (DNAM-III) unit was March 31, 2020 (see End-of-Life notice EOL9699), Cisco encourages affected customers to reach out to their Cisco representative and discuss the migration to a newer solution.

There have been no reports of an incident in customer settings related to this issue.

Background

Cisco has identified an assembly issue on a very limited number of the DNAM-III units used in the Cisco TelePresence Profile 42-inch, Cisco TelePresence Profile 52-inch, and Cisco TelePresence Profile 55-inch series.

Potentially affected units are limited to those produced between December 16, 2013 and March 2, 2014.

Problem Symptom

Affected units might experience an electrical short circuit.

Workaround/Solution

Cisco recommends a product migration of affected units for this issue as no workaround is available.

Step 1: Enter the System Serial Number into the search box of the Cisco Serial Number Validation Tool and this tool indicates whether or not the system is affected.

If the System Serial Number query result shows the status "Affected", proceed to Step 2. If the query result shows the status "Not Affected" then no further action is required.

Step 2: Enter the DNAM-III unit serial number into the search box of the Cisco Serial Number Validation Tool and this tool indicates whether or not the DNAM-III unit is affected.

If the DNAM-III Unit Serial Number query result shows the status "Affected", Cisco recommends that affected customers reach out to their Cisco representative and discuss a migration to a newer solution as no workaround is available. If the query result shows the status "Not Affected" then no further action is required, except reinstallation of the DNAM-III unit and the rear door.

How To Identify Affected Products

Identify the System Serial Number

The System Serial Number is located at the front side of the Cisco TelePresence Profile system, behind the front door, at the bottom area. In order to access the System Serial Number, follow these steps:

1. Open the front door on the Profile system.
2. The System Serial Number can be located at the bottom area, behind the codec as illustrated by the blue square in the above picture.

Identify the DNAM-III Unit Serial Number

The DNAM-III unit is located at the rear side of the Cisco TelePresence Profile system, behind the rear door at the bottom.

The serial number can be found on the bottom side of the DNAM-III unit and in order to access the serial number, follow these steps:

1. Loosen the screw that is used to stop the door in order to remove the rear door on the Profile system.
2. Tilt the door down and out.
3. Remove the three screws that hold the DNAM-III unit (from the plate above the DNAM-III unit).
4. The DNAM-III unit is now loose and two cables on the rear side and left side must be removed before the DNAM-III unit can be taken completely out of the column.
5. The serial number is located on the bottom side of the DNAM-III unit.

When the DNAM-III Unit Serial Number has been located, follow the instructions outlined in the Workaround/Solution section.
