Defect ID | Headline |
CSCwb57624 | Some C9300/C9300L switches may experience 'BOOT FAIL W', SINGLE_BIT_ERROR logs and/or kernel crash |
A limited number of dynamic random-access memory (DRAM) components in Cisco Catalyst 9300 Switches shipped from Cisco are impacted by a known issue in the memory supplier's manufacturing process. This issue can result in a higher rate of failure.
In this case, a manufacturing deviation in specific DRAM components was contained to a specific date range. Since the discovery of this deviation, additional limits have been imposed on the manufacturing process to help prevent future components from experiencing this process variation.
Most memory components in the affected Cisco Catalyst 9300 Switches with this manufacturing deviation will exhibit persistent, correctable memory errors. If left untreated, the affected units can eventually encounter an uncorrectable memory event. If encountered during runtime, uncorrectable errors may cause an unexpected switch reset.
The following symptoms may be seen:

Cisco recommends replacement of the affected Cisco Catalyst 9300 Switches in order to avoid potential device failure.
Replacement Instructions: First, validate the serial number(s) of the affected units as described in the How to Identify Affected Products section of this field notice. Then, see the Upgrade Program Information section for replacement instructions.
Return the Affected Device: Once the affected devices have been replaced, they need to be returned to Cisco. Instructions for how to raise a case for returning the device are provided in the Additional Information section. Note that this process is separate from our standard return process, which is typically included within the Return Merchandise Authorization (RMA).
Important notes for replacement orders:
To determine if a serial number is affected, see the Serial Number Validation section of this field notice.
Do not use the information in this section to submit replacement orders. For instructions on how to request a replacement, see the Upgrade Program Information section of this field notice.
Return the Affected Device
Once the affected devices have been replaced, go to Support Case Manager to raise a case for returning the affected device, either one by one or in bulk. To initiate the case, complete the following steps:
Cisco provides the Serial Number Validation Tool to verify whether a device is impacted by this issue. To check the device, enter the serial number in the Serial Number Validation Tool.
Important: For security reasons, you must click the Serial Number Validation Tool link that is provided in this section. Do not copy and paste the link into a browser. Use of the Serial Number Validation Tool URL external to this field notice will fail.
Support Case Manager (SCM) must be used for ordering replacement parts for this Field Notice. To open SCM in a new tab, click the following link:
https://mycase.cloudapps.cisco.com/fieldnotice?fn=FN72416
SCM will validate eligibility and ensure that a request for a particular serial number has not already been submitted. If there is already a request, SCM will indicate RMA already submitted and NOT eligible for replacement.
Provide the following information:
Order entry supports up to 50 serial numbers per request. For more than 50, submit additional requests.
