Problem Description

The Cisco uBR10012 platform does not recognize the MC16C and MC16E linecards. Symptoms include NVRAM and bus errors, and MC16x line card failures.

Background

1. New programmable changes so the uBR10012 can recognize the MC16C and MC16E linecards.
2. Updated carrier design to prevent the possibility of capacitors at location C44 and C45 from shorting out on sheet metal rib.
3. LCP memory upgrade (64 to 256Mb) for planned future capability enhancements. Additional Memory is required to meet N+1 memory requirements when card is acting as a Protect Card. Without the additional memory, the card may not be able to store all N+1 database structures required for the 7 Operating Cards (Working Cards). There is no memory deficiency when card is acting as an Operating Card.
4. Bus error fix on the LCP card.

Problem Symptoms

Version 06 does not correctly report the ID of the Linecard inserted in the LCP.

Note: Additional Memory is required to meet N+1 memory requirements when LCP card is acting as a Protect Card ("+1" Protect Card). Without the additional memory, the card may not be able to store all N+1 database structures required for the Operating Cards ("N" Working Cards).There is no memory deficiency when the rev 06 card is acting as an Operating Card.

Workaround/Solution

Workaround:
There is no workaround.

Solution:
RMA the product for one of Rev 07 or higher according to the hardware identification section below.
