Initial Public Release
The uBR7200 cards (listed in the Products Affected section) might fail to boot up after a software upgrade or other user action where the board requires a power cycle operation.
Cisco has been working with some customers on an issue related to memory components manufactured by a single supplier between 2005 and 2010. These memory components are widely used across the industry and are included in a number of Cisco products.
Although the majority of Cisco products using these components are experiencing field failure rates below expected levels, some components may fail earlier than anticipated. A handful of our customers have recently experienced a higher number of failures, leading us to change our approach to managing this issue.
While other vendors have chosen to address this issue in different ways, Cisco believes its approach is the best course of action for its customers. Despite the cost, we are demonstrating that we always make customer satisfaction a top priority. Customers can learn more about this topic at Memory Component Issue web page.
PLEASE NOTE - The products listed in this Field Notice have lower than expected failure rates. This assessment is based on actual usage of affected memory components, observed field failure rates and product replacements since 2012.
A degraded component will not affect the ongoing operation of a device, but will be exposed by a subsequent power cycle event. This event will result in a hard failure of the device, which cannot be recovered by a reboot or additional power cycle. For these reasons, additional caution is recommended for operational activities requiring the simultaneous power cycling of multiple devices. This issue has been observed most commonly on devices that have been in service for 24 months or more.
If the uBR7200 card (listed in the Products Affected section) has been in operation for approximately 24 months, the uBR7200 card might fail to boot up due to memory failure during a power cycle event. This is caused by one or more of these actions:
- Upgrade the software
- Reload the entire product
- Reload after installation
- Online Insertion Removal/Replacement (OIR)
This issue does not affect boards while the boards are in operation. The board failure might occur after one or more of the actions listed are executed.
The card symptom observed is as follows:
Normal SmartNet and warranty entitlement rules remain in place and are applied by the Cisco Technical Assistance Center (TAC) if you experience a failure in one of the products listed in the Field Notice. In other circumstances, such as out of warranty or out of contract, Cisco encourages you to raise your concern directly with your Cisco account team.
Fix on Failure Replacement Guidelines: Request RMA product and memory modules through normal service support channels.
If you need assistance in order to determine which hardware part(s) might need replacement, consult the error messages documented in the Problem Symptom section.
For assistance with replacement part disposition, see the table shown here:
See Replacement of DIMM on the Cisco uBR7200 Series Routers in order to replace the memory modules on this product.
How To Identify Hardware Levels
Enter the show inventory command in order to obtain the Product ID (PID) of the card. If the CLI is not available, physically inspect the card in order to locate the PID.
