Problem Description

Some CRS-1 boards have been manually downgraded in the field to a ROMMON level that was lower than the minumum required ROMMON level for that board. Manually downgrading below the minimum ROMMON level for a board will render the board inoperable, and it will need to be RMA'd.

Background

Boards which have shipped from Cisco (from Manufacturing or from the Depots) will have a ROMMON version that will either be at the minimum required level for that particular board, or it will be higher than the minimum required level.

There have been instances in customer networks where boards have been manually downgraded below the minimum required ROMMON level. Downgrading a board below the minimum ROMMON version for a given board, or version of a board, will render the board inoperable. Downgrading a board below the shipping ROMMON level will regress some fixes and enhancements.

If ROMMON is downgraded below the minimum version, field reprogramming will not be possible, and the board will need to be RMA'd.

Do not manually downgrade below the minimum ROMMON level on any CRS-1 boards as it will render the boards inoperable.

Problem Symptoms

Sample error messages after downgrading ROMMON below the minimum level on an MSC:

Workaround/Solution

Solution:

Do not manually downgrade below the minimum ROMMON level on any CRS-1 boards as it will render the boards inoperable.

Also, it is highly recommended that ROMMON levels aren't downgraded below the level that ships out from Cisco. There is a risk that downgrading ROMMON on a board will regress some fixes and enhancements.

RMA any boards which have been manually downgraded and rendered inoperable.

Use the following Failure Class and Failure Code in the RMA request form:

Failure Class: Administrative Request Failure

Code: Field Notice Alert

Use the following Table to identify minimum ROMMON levels: CRS-1 Software/Firmware Compatibility Matrix.

Note: This table also lists the recommended minimum ROMMON level to upgrade to (for boards and for IOS-XR Releases).
