This is caused by one of more of these actions: If the suspected hardware has been in operation for approximately 24 months, the appliance might fail to boot up due to memory failure during a power cycle event. This issue has been observed most commonly on devices that have been in service for 24 months or more. For these reasons, additional caution is recommended for operational activities requiring the simultaneous power cycling of multiple devices. This event will result in a hard failure of the device, which cannot be recovered by a reboot or additional power cycle. This assessment is based on actual usage of affected memory components, observed field failure rates and product replacements since 2012.Ī degraded component will not affect the ongoing operation of a device, but will be exposed by a subsequent power cycle event. PLEASE NOTE: The products listed in this Field Notice have lower than expected failure rates. Customers can learn more about this topic at Memory Component Issue web page. Despite the cost, we are demonstrating that we always make customer satisfaction a top priority. 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. A handful of our customers have recently experienced a higher number of failures, leading us to change our approach to managing this issue. These memory components are widely used across the industry and are included in a number of Cisco products.Īlthough the majority of Cisco products using these components are experiencing field failure rates below expected levels, some components may fail earlier than anticipated. BackgroundĬisco has been working with some customers on an issue related to memory components manufactured by a single supplier between 20. The Adaptive Security Appliance (ASA) 5505 might fail to boot up after a power cycle operation. There were no defects filed with this field notice at the time of publication.
