I believe Cisco will replace the entire unit if it the device is covered by any active service contract or was covered by warranty prior of November 16, 2016 and any device shipped after that date is not affected by the bug. <br />
<br />
Thank You

Cisco has advised BT of an issue relating to a component manufactured by one of their suppliers that affects some Cisco Optical Networking, Routing, Security &amp;&nbsp;Switching products. In some hardware units, the <b>clock signal component </b>degrades over time. Cisco expects product failures to increase over time, beginning after the unit has been in operation for approximately 18 months. <br />
<br />
Can anyone advise how to spot the issue and what symptom to look for if the unit has suffered such a defect?

Clock issue with Cisco ISR 4000K Series routers

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

Cisco PIX is a dedicated hardware firewall appliance; the Cisco Adaptive Security Appliance (ASA) is a firewall and anti-malware security appliance that provides unified threat management and protection the PIX does not. Other Cisco devices and systems include routers, switches, storage networking, wireless and the software and hardware for PIX Firewall Manager (PFM), PIX Device Manager (PDM) and Adaptive Security Device Manager (ASDM).

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
