Symptoms

Impacted PCI Riser Cards go off-line.  There may be visible physical damage to the card as well as an associated odor.

Impact

It has been determined through recent evidence at our external manufacturer, and from the analysis of a single customer incident, that there is a risk of riser cards failing in the Netra X4270 platform.

As the PCI Tray is plugged in and out of the riser cards a resistive short may occur due to the ground plane extending near the chamfered edge of each card, leading to visible physical damage to the card as well as an associated odor.

Changes

Contributing Factors

The Netra X4270 is configured with 3 PCI Riser cards; a passive riser card (p/n 371-4748) in slot 0, and active riser cards (p/n 371-4749) in slots 1 and 2.  All three riser cards are impacted by this issue.

This issue is due to a manufacturing defect that has resulted in an approximate 0.07% failure rate to date.

The potential for this failure is small and only occurs when removing and/or installing the PCI Riser Card.

Below is a table showing suspect versus good Riser cards.

      Suspect Part Numbers                               New Good Part Numbers
542-0269 - PCI Riser FRU                          7023544 - PCI Riser FRU
 -371-4749 - Active PCI Riser Card              - 7023540 - Active PCI Riser Card
 -371-4748 - Passive PCI Riser Card            - 7023681 - Passive PCI Riser Card

Cause

A defect in the manufacture of the PCI Riser Cards has been identified. This defect can result in a resistive short between ground and +12 volts. This defect is due to the ground plane extending near the chamfered edge of card, leading to riser card failure. A change has been made to the PCB which will increase the separation of the ground plane extending near the chamfered edge of card through the release of a new FRU part number of 7023544 via ECO# E0005353, which includes one passive riser card (p/n 7023681) and two active riser cards (p/n 7023540).

Solution

Target Completion Date: December 31, 2012

After the above date the implementation defaults to Upon Failure only.

Workaround

No workaround available - see Resolution section below.

Resolution

Hot Swappable: No - the Mezzanine tray must first be removed.

Proactive remediation activities will depend on customer contract situation and parts availability. Therefore, the Region FCO Leads are working the affected customer list and submitting FCO SR Creation requests to TSC Level 0.  The TSC will reassign SRs to the field for those customers who warrant on-site remediation per their contract terms, otherwise the TSC will handle SRs as Parts Only.  Refer to the below URL for more information on the FCO SR creation process:

  http://my.oracle.com/site/cs/758/1942/10310/12620/12759/index.htm

From this page open the document titled 'FCO SR Creation Template and Regional Representatives'.  In the individual Region Reps tabs you will find the submission alias for that Region and the personnel authorized to submit requests to L0.

If the system contains an active riser card (p/n 371-4749) and/or a passive riser card (p/n 371-4748) order new FRU part number 7023544 and replace all of the riser cards in the system. This new part number is a CRU (Customer Replaceable Unit) and includes 1 passive riser and 2 active risers.

A Customer Letter and Customer Letter Cover Sheet are available as attachments to this knowledge article.

The Netra SPARC T3-1 Server Service Manual (attached) has instructions on how to remove and install the PCI Mezzanine Board (pages 171-119 - section titled Servicing the PCIe2 Mezzanine Board), which includes images.


Identification of Affected Parts (how to)

Netra X4270 systems with a serial number prior to 1125FMK00U are impacted by this issue.

Impacted Riser cards can be verified electronically via the ILOM Command Line (example below):

  Defective Part # installed:
  -> show /SYS/MB/RISER1
  fru_part_number = 371-4749-02

Note: only Riser 1 and 2 part info can be accessed, however all three Risers are replaced as a FRU set.

Alternatively you can used ILOM Web Gui or IPMITool Output (ipmitool -H < Service Processor address> -U root fru)


Hardware Remediation and Material Availability Details

Not all Regions were materially ready at the time of FAB publication.  Please note the estimated readiness dates for each Region below;

  NAMER    - Ready
  EMEA       - 24-Dec-2011
  JAPAC     - Ready
  LACR       - Ready

Check with your Logistics Representative or TZ / Country / Area FCO Manager for more information with regard to material availability and the parts ordering process for this FCO.

This CRU is being temporarily changed to consumable, and will be changed back to repairable after this proactive remediation is complete.

Comments

This FCO is to be offered to all affected customers of record, regardless of contract/warranty status.
Service Requests (SRs) should be opened for non-contract customers using a dummy CSI.

Internal Comments

Removed the following from the beginning of the Resolution section replacing it with the current verbiage:

Proactive remediation activities are being managed by the TSC L0. The TSC will reassign SRs to the field for those customers who warrant on-site remediation per their contract terms.
