ME-3600X-24CX-M devices that have Cisco IOS software releases (15.2(2)S1, 15.2(2)S2, 15.2(4)S, 15.2(4)S1, 15.2(4)S2, 15.3(1)S, 15.3(1)S1)

Problem Description

A new hardware revision of ME-3600X-24CX-M (V02) is scheduled for release by the end of April. V02 is not backward compatible with previous Cisco IOS© software releases and will not boot up with these older software releases:

  • Release 15.2(2)S1
  • Release 15.2(2)S2
  • Release 15.2(4)S
  • Release 15.2(4)S1
  • Release 15.2(4)S2
  • Release 15.3(1)S
  • Release 15.3(1)S1

Customers should migrate to one of the latest releases of the Cisco IOS software: 15.2(4)S3, 15.3(1)S2, or 15.3(2)S.

Background

Cisco has upgraded to the latest revision of the ME-3600X-24CX-M hardware (V02) in order to improve yield from the manufacturing process. V02 will be rolled out by the end of April.

V02 is interchangeable only if one of the latest releases of the Cisco IOS software is being used: 15.2(4)S3, 15.3(1)S2, or 15.3(2)S.

Problem Symptoms

Once the new hardware is released by end of April, customers who order replacements (RMAs) for ME-3600X-24CX-M will get the new revision of hardware (V02). Refer to How to Identify Serial Number and Hardware Revision in order to check the revision of the product.

This new hardware revision (V02) will not boot up with the these older releases of the Cisco IOS software:

  • Release 15.2(2)S1
  • Release 15.2(2)S2
  • Release 15.2(4)S
  • Release 15.2(4)S1
  • Release 15.2(4)S2
  • Release 15.3(1)S
  • Release 15.3(1)S1

If customers have hardware revision V01, Cisco recommends they upgrade to one of the latest Cisco IOS software releases - 15.2(4)S3, 15.3(1)S2, or 15.3(2)S - by April 30, 2013. This upgrade will stop this problem from occurring.

Workaround/Solution

The latest Cisco IOS software releases - 15.2(4)S3, 15.3(1)S2, and 15.3(2)S - are available and work with the latest revision of this hardware (V02).

Customers are requested to migrate to one of these Cisco IOS software releases before April 30, 2013.

There is no change to the specification of the product and no change to form factor, functionality, power consumption or compliance.

Frequently Asked Questions (FAQs)

Q. With this new revision, do I need to restart a new certification cycle?
A. No. The hardware is interchangeable, and what you have tested with the old version is applicable to the new one.

Q. What was changed in the hardware?
A. To improve manufacturing yield, one component was upgraded to a new revision. This is the only change that was performed, and the change has no effect on current functions and behaviors.

Q. What is the improvement in manufacturing yield?
A. With this new component, the manufacturing process is improved to provide better yield. This revision is related to process improvement, and there is no quality issue with the existing component.

Q. How can I identify the revision of the product?
A. The revision number is the Version ID (VID) on the label on the switch. The new revision will show a VID of 02. Refer to How to Identify Serial Number and Hardware Revision in this field notice to identify the version of your hardware. You can also use the show version command-line interface (CLI) command to obtain the VID.

Q. Why is the existing software not compatible?
A. The vendor provided a patch to an API, which required a minor code change in the Cisco IOS software. The changes for both the API and the Cisco IOS software are very minor (<100line), do not relate to functionality, and simply clean up a traceback message triggered at bootup time. This minor patch has no effect on the existing product.

Q. Does this change have any impact on any other component, such as licensing or Management Information Base (MIB) information?
A. No. Other than the VID version to be updated, the change does not impact software components such as licensing or MIB support. The VID is not used by any components in software, and licensing does not use the VID.

Q. With two revisions of the product, do I have to track different software releases, IOS images or Bug IDs?
A. No. There will be one Cisco IOS software image with the same roadmap for both revisions of the product. Bug fixes will be integrated in that image and will apply to both revisions.

Q. What testing has been performed on this new revision and the Cisco IOS software change?
A. The code change has passed Regression test, Development test and System test. The new revision of the hardware has passed Electronic Design Validation Test (EDVT) and Optical Design Verification Test (ODVT).
