CTS-CODEC-SW - 1.1

Affects all CTS-CODEC-SW versions 1.1.1(332) and earlier.

Problem Description

This Field Notice addresses two problems:

1) The main filesystem on the compact flash fails to mount on CTS-CODEC-PRIM and CTS-CODEC-SEC running versions 1.1.1(332) and earlier.

2) The Field-Programmable Gate Array (FPGA) device becomes corrupted during an upgrade on CTS-CODEC-PRIM and CTS-CODEC-SEC for versions 1.1.1(332) and earlier. This is a non-recoverable failure and the codec must be replaced.

Background

When the main filesystem on the compact flash fails to mount, all configuration data is lost and the system comes up in its factory default state. The filesystem fails to mount because of corruption to the filesystem or the compact flash partition table entry associated with the mounted filesystem. If corruption to the compact flash partition table occurs, the codec must be returned and its compact flash replaced and reformatted.

The corruption of the FPGA device occurs when a user power cycles the TelePresence codec during the process of an FPGA upgrade. An FPGA upgrade may take place during new image installation if there were changes to the FPGA logic. The FPGA upgrade process is automatic and no user intervention is required. If the FPGA device becomes corrupted, the TelePresence codec will not boot properly.

Problem Symptoms

When the main filesystem on the compact flash fails to mount, the endpoint loses its configuration information, cannot register with Cisco Unified Call Manager, and comes up in a factory default state after a reboot. Reconfiguration from Cisco Unified Call Manager is not possible, since the configuration information can no longer be saved.

When an FPGA corruption occurs during an upgrade, the TelePresence codec will fail to boot up. The user has no access from phone or WEB UI.

Workaround/Solution

The recommended solution to minimize compact flash corruption and to minimize the possibility of FPGA device corruption is to upgrade the TelePresence codec firmware to version 1.1.1(348D) (registered customers only) or later.

Codec firmware version 1.1.1(348D) contains the following enhancements:

1) Reduces the number of write cycles to the compact flash to prevent premature wear and bit error accumulation in compact flash sectors.

2) Reduces the amount of time required for an upgrade to complete. A visual indicator has been added for when the secondary codecs are upgrading, this is similar to the indicator for when the primary codec is upgrading.
