Problem Description
The NCS1K-CNTRL unit might fail after 18 months or longer in operation due to a clock signal component failure.
Background
A clock signal component manufactured by one supplier, and included in some Cisco products, has been seen to degrade over time in some units.
Although the Cisco products with these components are currently performing normally, we expect product failures to increase over the years, beginning after the unit has been in operation for approximately 18 months.
Once the component has failed, the system will stop functioning, will not boot, and is not recoverable.
These clock signal components are used by other companies and are included in a number of Cisco products.
Problem Symptom
The product will no longer function and, subsequently, the system fails to boot.
Workaround/Solution
Customers with affected products (see the How To Identify Affected Products section) should contact the Cisco Technical Assistance Center (TAC) to get a replacement unit.
To open a Cisco Technical Assistance Case (TAC), you must have a valid support contract or a product that is under warranty.
How to Identify Affected Products
In order to verify if your product is affected by this issue, examine the version ID (VID) number.
Any unit with a VID number equal to or earlier than the Possibly Affected VID numbers in the following table may be affected.
Any unit with a VID number equal to or later than the Fixed VID number in the following table is not affected and will not be replaced.
| Affected PID | Replacement PID | Possibly Affected VID | Fixed VID |
|---|---|---|---|
| NCS1K-CNTLR= | NCS1K-CNTLR= | V01, V02, V03 | V04 |
