A series of recent security bulletins from Cisco, on February 2nd, detail an issue that has been discovered in several of their devices. Here is a summation:

Cisco ASA Security Appliances

FN-64228 : ASA 5506, ASA 5506W, ASA 5506H, ASA 5508, and ASA 5516 – these models all use the same clock signal part from the same vendor which has been found to degrade over time. After 18 months of continued operation this component will fail and cause the device to stop functioning, no longer boot, and will not be recoverable.

“Customers with affected products that are under warranty or covered by any valid service contract as of November 16, 2016 should go to the Clock Signal Component Issue page and follow the instructions in order to request replacements.” These replacements will be prioritized based on time in operation.

Meraki Router & Wireless APs

Meraki Notification – MX 84 & MS350 Series – these models all use the same clock signal part from the same vendor which has been found to degrade over time. After 18 months of continued operation this component will fail and cause the device to stop functioning, no longer boot, and will not be recoverable.

” Meraki will reach out to customers via email and on the dashboard to arrange replacement and the return of affected units.”
