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.
This issue has been root caused to a BOM change on the ML1000-2.
A recent BOM change introduced by ECO (E094946) to replace an EOL'd Ethernet Transceiver (15-3823-02) in the PHY PLL Loop circuit to a new Ethernet Transceiver (15-3166-01) was not complete.
The new device (15-3166-01) requires an additional passive device adaptation in order to have the same PLL locking performance of the original part (15-3823-02).
In order to resolve this problem, deviation D107790 and ECO E100051 have been issued to add the passive devices needed to restore the PLL locking performance of the ML1000-2 card.
This field notice recalls and reworks all affected units produced using 15-3166-01 to provide the necessary passive device adaptation under ECO E100051.
The link between the 15454-ML1000-2 and the CAT4507 (specifically) will go down when auto negotiation is enabled on each side of the link.
As a workaround, customers can disable auto negotiation on both sides of the link between the CAT4507 and the 15454-ML1000-2.
Replacement of affected hardware is recommended.
New products that were manufactured under Engineering Change Order (ECO) E100051 are guaranteed to be free of this problem. Refer to the "" section for instructions on how to identify affected in-service product.
Product shipped from Service Logistics might still exhibit this problem. In order to ensure an RMA replacement is NOT affected by this problem, request an RMA coded as shown here:
Service Level: Mfg New - 3rd Bus Day NON BILLABLE
Failure Class: Administrative Request
Failure Code: Field Notice Alert - FN63305
Note: Service level agreements do not apply to RMAs coded as shown above.
