Problem Description

There is a potential infant mortality component issue which can cause a variety of failures on the ESR-6CT3 line card. More specifics about this failure can be found in the Problem Symptoms section of this notice.

Background

The material used in the packaging of the Line Interface Unit (LIU) devices can fail to provide adequate electrical isolation between the device leads. During early months of operation the component may develop short-circuits internally. If the failure is to occur, it will most likely occur within the first months of operation. If failure doesn't occur within that time frame, the potential for failure decreases.

Problem Symptoms

This is a physical layer problem on the DS3. The T3 controler status changes to down or bounces between up and down.

This condition can additionally manifest itself with one or more of the following symptoms:

  • The following message in the PRE log:

C10K-4-LC_WARN: Slot[4/0] 6cht3-1 T3[0] T1[1] Lunar
Performance Monitoring data not latched for
collection
  • The following message in the PRE log :

C10K-3-LC_ERR: Slot[3/0] 6cht3-1 DataPathControl:
Hardware error - Status1=0x000072C1,
Status2=0xCC1
  • The following message in the PRE log :

%C10K-3-LC_ERR: Slot[3/0] 6cht3-1 DataPathControl:
i960[0] With different errors like: ERROR_I960FAULT ERROR_I960NMI
MEMERROR_SINGLE
  • The CT3 linecard crashes, followed by this message sequence in the PRE log :

%C10KEVENTMGR-1-IRONBUS_FAULT: Ironbus Event 3/1, Restarting Ironbus:
%IPCOIR-3-TIMEOUT: 
Timeout waiting for a response from slot 3/0
%IPCOIR-2-CARD_UP_DOWN: Card in slot 3/0 is down
%IPCOIR-5-CARD_DETECTED: Card type 6cht3-1 (0x165) in slot 3/0
%IPCOIR-5-CARD_LOADING: Loading card in slot 3/0

Workaround/Solution

The solution to this issue is to replace the failed board. Due to the very low failure rate attributed to this issue (approximately one percent), Cisco recommends a replace on failure strategy. Logistics stock will be purged, but please note that a worldwide logistics purge can take several months. In the interim, to assure that a board is at the latest revision, return materials authorization (RMA) requests for ESR-6CT3s can be coded as Administrative Request - Field Notice (ARFN). This specifies that the replacement is a new unit from manufacturing.

This field notice will be updated when the logistics purge is completed..

How To Identify Hardware Levels

The revision of the top level assembly (TAN) number of the ESR-6CT3 has been changed. An ESR-6CT3 with a TAN of 800-05547-05 or higher is not affected by this field notice. The TAN of the ESR-6CT3 can be seen in the output of a show diagnostics command as shown in the example below.

Note: The ESR-6CT3 in this example is at rev -04 and is subject to the information in this field notice.
