Initial Public Release
The Anomaly Detector Modules (ADM) and Anomaly Guard Modules (AGM) (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 suspected hardware has been in operation for approximately 24 months, the module might fail to boot up due to memory failure during a power cycle event caused by one or more of these actions:
Note: The issue does not affect modules while the modules are in operation. The board failure might occur after one or more of the actions listed are executed.
- Upgrade the software
- Reload the entire system chassis
- Reload after installation
- Online Insertion Removal/Replacement (OIR)
- Recover from a power outage
The Anomaly Detector and Anomaly Guard Module symptoms observed are shown here.
In the boot-up cycle, this error message might appear in the console log:
NP status: FAILURE
NP status: FAILURE
NP status: READY
NP Boot timed out. Operational code not downloaded. Reset System
FATAL ERROR: Couldn't initialize the Network Processors!!! Please reboot the system.
Fix on Failure Replacement Guidelines: Request RMA product through normal service support channels.
How To Identify Hardware Levels
Enter the show inventory command in order to obtain the Product ID (PID). If the CLI is not available, physically inspect the module in order to locate the PID.
