Defect Information

Defect ID	Headline
CSCvu22621	Add support for Die Shrink RLDRAM for Cylons

Problem Description

The cBR-8 line card with the new Reduced Latency Dynamic Random-Access Memory (RLDRAM) Controller (Version ID (VID) V09 and higher) requires a different FPGA image. As a result, it will not fully boot if inserted in chassis that run Cisco IOS^® Release 17.2 or earlier.

Background

The updated Cisco cBR-8 line card is being released with a new RLDRAM Controller due to the obsolescence of the current RLDRAM Controller by the manufacturer. This line card requires the cBR-8 system to run with Cisco IOS XE Release 17.3.1w or later.

This new version of line card (V09) is marked with a yellow label on the card as well as on the handle.

Problem Symptom

The cBR-8 line cards with the new RLDRAM Controller (V09 and higher) will not fully boot if inserted in chassis that run Cisco IOS Release 17.2 or earlier.

These errors might be observed on the console when new line cards (V09 and higher) are inserted in systems that run Cisco IOS Release 17.2 or earlier.

These messages indicate that the line card has crashed. A core file will be generated and stored in /harddisk/core. If redundancy is configured for this line card, a line card switchover will be initiated. If there is no redundancy, the line card will be in a boot/crash loop, which creates new core files each time.

Workaround/Solution

Customers should upgrade the cBR-8 system software to Cisco IOS XE Release 17.3.1w or later before installing the new cBR-8 line cards which contain the new RLDRAM Controller. This is true whether the line card is received as a result of a new order or due to a Return Material Authorization (RMA).

cBR-8 software releases that support the V09 and higher line card are:

Cisco IOS XE Release 16.12.1z1
Cisco IOS XE Release 17.3.1w or later

Notes:

There is no impact on existing cBR-8 line cards (V08 or lower) currently in the field. These cards will continue to function properly with the new Cisco IOS XE software releases mentioned in this field notice. The intent is to add support for the new line cards.
Basestar FPGA will be updated accordingly while cBR-8 systems will be upgraded with the new Cisco IOS software release. Hence, there is no separate package needed for the firmware.

How To Identify Affected Products

cBR-8 Line Card

New cBR-8 line cards with the new RLDRAM Controller are marked with a yellow label on the card and on the handle as shown in this image.
