2960x - 15.2.4E6 Error - POST ACT2 Test Failed

Today we upgraded 8 WS-C2960X-48FPD-L switches to 15.2.4E6 using c2960x-universalk9-tar.152-4.E6.tar

 

For 3 of them the upgrade was completed with no errors. The rest 5 all had the same issue;

After the reboot we got the error message

The fiber module would not work and the faulty ones that were in stack would not recognize each other.

After some research on the issue I came upon

https://community.cisco.com/t5/switching/ilet-1-authentication-fail-on-2960x-after-ios-update/m-p/3682974

https://www.cisco.com/c/en/us/support/docs/field-notices/639/fn63972.html

 

I removed the power for 10 minutes on all affected switches with no success.

 

I removed all stack modules and sfp+ cards and I also tried

c2960x-universalk9-tar.150-2a.EX5

c2960x-universalk9-tar.152-2.E4.tar

c2960x-universalk9-tar.152-2.E7.tar

c2960x-universalk9-tar.152-2a.E1.tar

c2960x-universalk9-tar.152-6.E1.tar

 

After each install I would remove power (cold reboot) the sw

 

and the error persists...

 

Do you have any suggestion, before I start the hardware replacement procedure?

Raise a TAC Case.  This is a very, very well-known bug, CSCur56395 (1,276 Support Cases as of 01 August 2018!).

Hello

Have you validated that those five switches flex-stack modules serials are in/out of scope regards that cisco field notice - here



kind regards

Hi,

thank you for your suggestions

Hello,

 

I opened a TAC case. It appears there was nothing I could do and they replaced the switches. RMA

 

Opening a TAC case is the recommended action.

ihhhhhgood morning :

 

I have exactly same issue, how did you solve it?

Re: 2960x - 15.2.4E6 Error - POST ACT2 Test Failed

Add 15.2(4)E8 to this list.... lost 2 switches with stacking modules last night with the exact same symptoms.

Re: 2960x - 15.2.4E6 Error - POST ACT2 Test Failed

well my advice:

after a week trying multiple solutions, nothing work. So I open a RMA with
cisco and they sent me a New one.

Re: 2960x - 15.2.4E6 Error - POST ACT2 Test Failed

I have seen this issue in all its various forms, whether relating to the SFPs, the stacking modules or the switch itself.  I was recently upgrading all 2960X stacks to remediate a security vulnerability.  I successfully upgraded 49 stacks at various sites without incident.  I am unsure how many switches that represents but at least 150.  Then I moved on to a site in Europe with 22 switches in very small stacks of 1 - 3 switches.  I loaded them all with 15.2(4)E7 and before my maintenance window came one of the stacks of 2 switches reloaded due to a power failure.  I received the POST: ACT2 Authentication : End, Status Failed boot message followed by the %ILET-1-AUTHENTICATION_FAIL: This Switch may not have been manufactured by Cisco IOS message on one of them while the other one upgraded successfully.  So they grabbed a brand new spare off the shelf and I did an IOS upgrade on that before adding to the stack.  It also failed with the same error.  A second spare upgraded successfully.

I tried everything I could think of to resurrect the 2 switches.  Tried the published power cycle trick with no success.  Tried factore reset, various IOS images including the original one with no success.  Finally called TAC and had the 2 failed switches RMA'ed.  Through some mixup they sent 4 switches.  One of the switches was DOA.  

 

Since then I have upgraded 10 additional switches one stack at a time and have had 2 more failures.  I have 10 more to go but we need to RMA some more switches first.  I need to be sure that I have enough switches on hand to cover a failure of every stack member.  Luckily at this site the most switches in any one stack is 3.  My biggest fear is an extended power outage at the plant and they will all reload.  How many will survive is anyone's guess.

 

It would appear that once this occurs there is no software remedy so by definition this is a hardware failure of some sort.  I have to believe Cisco knows what causes the failure and what serial numbers might be affected.  But I have never seen this published.  My theory is that there is such a huge number of possibly defective switches that they are just not willing to proactively replace them all.  So that means I have to slog through these upgrades one at a time and hope for the best.

Jeff;

 

Thank you for your detailed response, I am working with my Cisco Account manager and the SE on the ones I had recently do this.

I agree I think Cisco knows what is going on and is not saying anything due to the financial impact, as such I am currently starting to deploy a different switch than the 2960X due to this issue, and may go as far as looking at other vendors for access switches as I can not have this happen when I am trying to remedy a security issue just as you were doing.
