| CSCvs42280 | C9200L/9200 : Stack Cable or Stack Adapter or Uplink FRU module (NM) hardware authentication failed |
Problem Description
A set of stacking cables, stack adapters, and network modules, as mentioned in the Products Affected section, will fail to authenticate when inserted into a stack port or the network module slot of C9200/C9200L switches.
Background
A specific set of stacking cables, stack adapters, and network modules manufactured during a short period of time between September 2019 and January 2020 (identified by the serial number) have incorrect/missing Cisco Manufacturing authentication data. This will leads to failure during bootup/installation of the switch. The issue was caused by a very specific manufacturing process deviation that has been corrected with the introduction of additional verification steps into the process.
As of January 2020, the set of improperly manufactured units represents less than 1% of the entire install base.
Problem Symptom
The affected product will fail to authenticate when inserted into the stack port or network module slot. This failure will be noticed during system bootup. Any product that did not encounter an authentication failure and is already in use/functional/service was manufactured correctly and will not run into this issue/failure.
On authentication failure, the affected product should show one of these problem symptoms.
Stacking Cable Authentication Failure
The stack switch will reload and might show any of these error messages:
*** Stack cable authentication failed for cable inserted on stack port 1 on switch 2 *** *** Stack cable authentication failed for cable inserted on stack port 2 on switch 2 *** *** Stack cable authentication failed for cable inserted on stack port 1 on switch 1 *** *** Stack cable authentication failed for cable inserted on stack port 2 on switch 1 ***
Stack Adapter Authentication Failure
The stack switch will reload and might show any of these error messages:
Stack Adapter Auth Fail : SIF_SERDES_CABLE_EASTBOUND *** Stack adapter authentication failed on stack port 1 on switch 1 *** Stack adapter authentication failed on stack port 2 on switch 1 Stack Adapter Auth Fail : SIF_SERDES_CABLE_WESTBOUND
Network Module Authentication Failure
The network module and corresponding ports on it will not work, but the rest of the switch will continue to operate correctly. It might show the error message as:
***Uplink FRU module hardware authentication failed***
Workaround/Solution
There is no workaround for this issue. Cisco is proactively notifying its customers of the potential field issue via this notice. This issue will be seen across a small set of units manufactured between September 2019 and January 2020.
If the issue is observed as mentioned in Problem Symptom section, and the serial number is listed in the Serial Number Validation Tool, use the Upgrade Program section in this field notice to submit a replacement request.
Cisco customers can return the impacted stacking cable, stack adapter, or network module to Cisco or choose to dispose of the unit at the customer site.
If the switch fails with a similar symptom, but is not included in the Serial Number Validation Tool, the customer should create a Cisco Technical Assistance Center (TAC) case to get further assistance before attempting to replace the product.
Cisco is committed to the delivery of high quality units and regrets any inconvenience that this might cause. Contact TAC or your account team for further support.

Upgrade Program
A Form must be filled out for each separate Ship to Address.
The Upgrade Order Reference Number should be unique for each time the Form is filled out.
Please enter a valid Serial Number in the Form.
You will receive an acknowledgement email immediately after submitting the Form with Request #. Depending on material availability, both you AND the Customer email address will receive a confirmation email with Order# in 7 to 10 days.
