Workaround/Solution

Cisco is recommending customers to identify the Serial Number and the hardware revision of their DS-X9032 linecards and DS-X9032-SSM storage service modules. Please refer to How to Identify Hardware Levels section of this field notice for details on serial numbers and hardware revision of the affected modules.

If the linecards serial number and the hardware revision are verified to be affected then customers should replace the linecard by calling the Cisco TAC and requesting an RMA replacement.

Important: When using the standard RMA process to replace these units please use the code ARFN (Administrative Request Field Notice).

How To Identify Hardware Levels

How to verify if you are affected:

Step 1. Verify if you are within the range of affected serial numbers:

The affected DS-X9032 has a serial number within the range JAE1138xxxx and JAE1139xxxx

The affected DS-X9032-SSM has a serial number beginning with JAE1133xxxx

Note: Of the linecards that fall in these serial number ranges, only a few in each range are affected.

Step 2. Validate the serial number is affected by using the Serial Number Validation tool:

For DS-X9032: Serial Number Validation for DS-X9032

For DS-X9032-SSM: Serial Number Validation for DS-X9032-SSM


Step 3. Check the Hardware Revision of the linecards.

The issue has been fixed in the following hardware versions of the products:

DS-X9032 - Issue fixed in Hardware Revision 6.5 and higher.

DS-X9032-SSM - Issue fixed in Hardware Revision 7.5 and higher.


Customers can use the show module command to obtain the Serial Number and Hardware revision of the linecards.

Example of Show Module Command Output:

Note: It is very important that customer uses both the Serial Number and the Hardware revision of the linecards DS-X9032 and DS-X9032-SSM to identify if the product is affected or not.

For Example: If the serial number of the DS-X9032 linecard comes out to be affected, but the HW revision is 6.5 or higher, then it is not affected as this issue has been fixed in the HW revision 6.5 and higher of DS-X9032.
