Codian 8510- Unexpected reboot

ginowrief
Level 1
Level 1

Hello,

MCU : Codian MSE 8510 Blade (configured in HD mode)

Software version : 4.2(1.46)
Build: 6.17(1.46)

The bridge has been rebooted unexpectedly this morning and we are actually investigating this problem. I would appreciate if you can help me and provide some ideas to identify this problem.

We suppose that it is an electrical factor as on the MSE Supervisor 8050 ,there is an error message:

Insufficient current capacity (requires at least 24.20A)

Do you think that there is a relation with this error message?

Hi Firdaush,

Could you please provide some background information :-

  • Is it a new installation?
  • Was it working before?
  • Have you calculated the power requirements when installing it for first time correctly?
  • how many blades are there in the chassis?
  • Could you also attach some brief snapshot of the event logs of the MCU.

Thanks,

Saurabh

I do believe the efficiency is 90-92% on that H Series rectifier.  Even at 90% will tell you, you will require 2 rectifiers to run that chassis.  But since you only have one, like I said, will generate the insuffcient capacity warning.

Hi Saurabh,

Sorry, its not the correct answer. Please maintain the request.

HI Firdaush.  How many rectifiers do you currently have in the powershelves right now? A and B? How many blades you currently running in this chassis?

Snapshot of Hardware>Blades and Hardware>Power Supplies would be helpful. 

If the blade rebooted on its own, you can download the diagnostic.zip file at the bottom of the status page and more likely open a TAC case if you want to.  If you want to post it here, thats up to you. 

This message, to me is indicating you don't have enough capacity to run what you have slotted in the chassis. It depends on what shelf is reporting this also. 

This may or may not be the cause of the issue, and hopefully the diagnostic.zip file will show something, or why it occurred.

Yeah. You may need to verify and add a 2nd rectifier to shelf B if possible.  What type of blades are they? All 8510's?

I'd check to see if you have another rectifier, and add it to shelf B.

The reboot is a different story, unless the diagnostic.zip file is looked at to be sure.  Hopefully it will shed some light.

Patrick,

What type of blades are they?

1 Codian MSE Supervisor 8050

2 Codian MSE 8510

3 Codian ISDN GW 8321

4 TPS 8710

Unfortunately, i won't be able to send you the diagnostic file as it contains confidential information. Sorry.

Patrick,

Is there any docs explaining to decode the diagnostic file contents ?

HI Firdaush.  No, there are no docs for that file.  This is used for TAC and BU purposes only.  If you were to raise a case with Cisco TAC, this file would be needed to try hopefully see what happened. 

Reference the insuffcient capacity issue, you can check the calculator page cause right now, if shelf A went down or lost power, shelf B, doesn't have enough power to run the chassis. 

You can run the calculator here:

http://www.cisco.com/en/US/docs/telepresence/infrastructure/articles/mse_8000_calculate_power_current_requirements_kb_386.shtml

90% efficiency on the rectifiers, you will require 2 rectifiers to run the chassis, but since B only has one, and if A were to go down, I don't believe you will have enough power to power the chassis.

How to know the effeciency of the rectifier?

I do believe the efficiency is 90-92% on that H Series rectifier.  Even at 90% will tell you, you will require 2 rectifiers to run that chassis.  But since you only have one, like I said, will generate the insuffcient capacity warning.

Perfect.

But do you think that the reboot is due to the incapacity electrical problem?

Nothing like a forum discussion to get you thinking about your own infrastructure and it's salability currently in the in the future when you're thinking about adding additional blades.

I have one question on the power rectifiers as the amount of rectifiers in my shelves are the same as Firdaush's.  We have two (2) rectifiers in shelf A and one (1) in shelf B, we currently only run one (1) 8510 blade but are looking to add an additional 8510.  If I'm calculating this correct, I would need to add another rectifier to shelf B for redundancy just in case A went down, correct?

Can someone tell me what the rectifier efficiency means as well?

Thanks, and sorry for butting into the regional discussion, but thought it was around the same lines and possible preventative measures as what was mentioned previously here would apply to my question.

@Firdaush - Not sure without checking out the file which I'm hoping would tell us what happened, but I can't be sure.  If you want, you can open a case for investigation if you would like us to.  The other rectifier would be important for you to look into also.

@Patrick. Yes, if you add additional blade to your chassis, use the calculator to see how many more rectifiers you may need here. Keep in mind redundancy also.  In case you need more on the other shelf as well.

Attached is the H-Series Rectifier data sheet if you need to know more about the efficiency etc.
