Clock Signal Component Issue

Cisco has recently become aware of an issue related to the clock signal component manufactured by one supplier.  The appliance with the affected component will continue to perform normally in its current running state even after component failure.  Once the appliance is rebooted administratively or due to power loss, the system will stop functioning and will not boot.  This component is not strictly used in Cisco devices as this very component is used in other appliances outside of Cisco.  Support is in place as Cisco will be replacing products that have this component for those customers with products under warranty or covered by any valid services contract dated November 16, 2016.

Please look at the below list of high level product family models and verify if you have any integrated, if so, please contact Daymark Solutions for appliance analysis.
