CPU Clock Component Issue

Juniper Networks was recently made aware of the existence of an errata on a clock signal component manufactured by a third-party supplier. This errata may result in the component degrading over time. Although we believe the Juniper products with this component are performing normally at this time as of 13th February, 2017, the above listed Juniper product model numbers could, after the product has been in operation for at least 18 months, begin to exhibit symptoms such as the inability to boot, or cease to operate. Recovery in the field is not possible. Juniper products with this supplier’s component were first placed into service in January 2016.

Pursuant to information provided by the component supplier, the issue is expected to manifest after an extended period of time in operation (18 months or greater). Juniper has worked with the component supplier to implement a remediation. All products shipping currently (as of 15th February, 2017) have the necessary remediation for this issue. In addition, Juniper’s global spare parts depots will be purged and updated with the remediated product. The completion date for the purge will be communicated as soon as practicable and this Notification will be updated. Due to logistical considerations the completion of the depot purge is targeted for the beginning of the 3rd quarter of 2017.  

Solution:

For parts under warranty or a valid service contract that have this component, Juniper will proactively replace these parts. Due to the age-based nature of the failure and the volume of replacements, Juniper will take the product’s time in operation into consideration.
