Cisco Field Notices
- Cisco has been made aware of a limited number of Supervisor-2 modules (DS-X9530-SF2-K9), manufactured between September 2007 and February 2008, that may randomly experience a Device-4 error caused by an Error Correcting Code Memory (ECC) error. This error will cause the Supervisor module to switchover. - The product release instruction (PRI) programmed in the modem does not match the PRI accepted by Cisco IOS®. This mismatch results in an unrecognized modem when it is installed into the 880G series routers. - The link between the CAT4507 switch and 15454-ML1000-2 does not come up with auto negotiation enabled on each side of the link. To date, this link issue has only been seen when the 15454-ML1000-2 and CAT4507 switch are interconnected. - A limited number of HP DL380-G6 servers shipped by HP prior to November 16, 2009 and configured with a system board revision earlier than revision "0S," may unexpectedly reboot. A user will see "Server Reset, Server Power Removed, Server Power Restored" message in the Integrated Lights-Out 2 (iLO2) Event Log. A user can determine if they have an affected server by looking at the serial number. It will be xxx947xxxx or earlier. - A majority of the MOSFETs provided by a specific supplier have been discovered to be marginal in design. These MOSFETs are part of the 2.5V power supply. The power supply is a push/pull design, where two devices are designed to alternate on and off, such that both are not driving at the same time. The problem MOSFETs have a very high turn off delay, resulting in simultaneous driving. When this occurs, one part can heat up, causing it to fail over time. - This software issue may affect customers using MGCP and CAS signaling feature on MGX VXSM board. Service Providers use CAS signaling feature for various call services. In rare circumstances, the software goes into a "race condition" between call process messaging and call is not getting cleared properly. The suspect circuit may appear in a hung state on the VXSM card. Once in a hung state, no future calls will succeed on the suspect circuit. This is a software issue - please do not RMA the VXSM board as the board is working properly. - OC768 cards operating on the CRS-1 chassis may encounter intermittent burst BER events several months after installation due to dendrite growth. A dendrite is a crystal with a tree-like branching structure that is formed when a metal, or an alloy of multiple metals, in liquid form freezes. Packaging contamination can allow molding compounds to absorb moisture through the package body and between the lead frame molding compound interface causing dendrite formation. Combined with moisture, this results in a lowering of resistance between tracks and pads and can lead to metal corrosion. - This issue affects specific subset of the PCMCIA ATA Disks and Compact Flash disks that were installed in specific Cisco routers manufactured between May 2005 and October 2006. Cards shipped individually as spares over that same time span may also contain one of the affected units. This issue has been linked to a component manufacturing problem. The root cause was identified and appropriate steps taken to resolve the problem. Product impact varies due to different flash memory access methodologies and use patterns. Some products may be able to mitigate the potential effect by re-writing affected memory areas at specific intervals. This feature does not work with all products, so please check the workaround section for availability and specific instructions. - This issue affects specific subset of the PCMCIA ATA Disks and Compact Flash disks that were installed in specific Cisco routers manufactured between May 2005 and October 2006.
