Power problem with Nortel 1120E & 1140E IP phones 3

[rpratali]

Over the last 6 - 12 months we've had a rash of 1120E & 1140E IP phones die left and right. On average we're loosing 2 - 10 phones per week. I've read that there is a possible capacitor issue with the phone related to overheating. Any idea on why all of a sudden we would see such a large increase in the amount of failures?

Absolutely, if you refer to my posts on here or this website:

You can see that it is running the phones at 1 gig that is causing the failures. Avaya will come fix them for about $16 per phone or send you boards for around $6 a phone for you to swap them out. Easy-Peasy if you are comfy with that.

Best of luck to you!

Hi, I am running 11xx on SIP and they are set at Auto, on a 1000 speed. Should I change them to 10BT?

 

[GordonKapesMZ4]

Should it be 100BT or 10BT to alleviate the overheating problem?

Thanks for the info Tman45. The only thing that is still a question for me is why did this just start happening? We've had these phones in place for years, running at 1 gig, with POE, in multiple locations, and didn't have any problems. The problems just started within the last 6 - 12 months.

Our phone our covered under a maintenance contract with our phone system provider. Therefore we're not paying additional amounts to get each phone fixed. However, it's driving me crazy having to constantly replace phones almost on a daily basis.

Unfortunately we can't afford to slow the speeds down to 10 / 100 MB.

One additional piece of information. About three months ago we worked with our network group and phone system provider to determine what the power output should be of the POE. The network group made some minor adjustments and the phones seemed to work fine with very very failures. However, two months later the failures skyrocketed again. Not sure why.

this is known issue , which avaya have known for the past 3 months..the corect fis is that thev capictor is to close to heat source on the card this should be a free fix...we had money back ffor a customer who had sent back 100+ 1140's..the phones with the issues were mostlt 2007 manufacture date....

To GordonK - I would not recommend decreasing the speed if you are using the phone for your data connection if you are running 1 gig NICs (that is silly). What you need to do is continue to run 1 gig and get new power supply modules from Avaya (enough to replace EVERY late-2007 phone). I do have a list of known bad ones as well <see below>.

Sorry I did not explain. With our situation we did not have Avaya PASS (nor extended warranty on the phones) so we have to pay to get ours fixed and yes this is really only an issue with phones from late 2007 from what I understand.

Yes, phones running 10/100 they have not seen an issue with (yet) so it is the increased speed that seems to cause the caps to overheat (they didn't rate them properly in design).

Basically the deal is that you NEED TO REPLACE ALL YOUR PHONES WITH THE NEW POWER MODULE. Otherwise, you will continue to have these random failures. No word on if the new power modules will fail, but our Avaya team said they should last 5-10 more years easily ... haha (sorry that is laughable to me)

Good luck to all with these issues!

I don't believe this is an issue with BCM 11xx phones, because the BCM is running 10/100. Have you hear anything about that end?

Also, on my SIP phones, I don't have any data running through the phones at this time.....so if I leave it at 10/100 will it really make a difference to call quality?

Thank you!

GKMZ4 I think you are good. If you were to upgrade desktop/laptop NICs to a Gig and run Gig then I think you may see failures in an undetermined amount of time. Again, Avaya has not yet seen ANY failures with people running 10/100 - only the Gig speed. If you are not running data thru the phone there is no reason to bump up to Gig speed ;D

Thank you Tman for your advice.

Thanks Joe, but the guy at bluemunkey deserves all the credit for posting about it! I just happened upon his site when doing a Google search on our issue!!!

Thank you TMan for this valuable information. We are currently experiencing the same issue with our 1120 and 1140 (about 850 phones purchased in Dec. of 2006). So far we had 40 devices replaced over the last few months.

Our device have no warranty so we contacted our Avaya customer support and they informed us that Avaya would issue an official document by today. Here is the URL where you can find it.

Thanks LBay for the link. Based on this new information I contacted our PBX / phone provider and provided them a copy of PNC 1745B. The good news is that they acknowledged the fact that Avaya released PNC 1745B. The bad news is that neither Avaya nor our PBX vendor will really do anything. Since our phones are currently covered under a maintenance agreement with our PBX vendor they will get replaced with properly repaired phones at no additional cost as they break. The other bad news is that they will not do anything for our remaining 600-700+ phones currently deployed that may be affected (ex. replace them all). So for now we have to continue to put up with the phones randomly breaking until the remaining phones have all been replaced with repaired phones. This could take a very long time. Needless to say I will busy for a long time replacing broken phones.

rpratali ... WEAK!!!!!! Avaya should replace them all with a team since you have the maint agreement!!! We did not have an agreement, but they did tell us that those with an agreement gets them replaced for free and that they would send a team to do them ALL ... not wait until they randomly break to repair them so go back to your vendor and/or Avaya and demand (especially since you have a contract. That is a bunch of BS if you ask me!! AND VERY POOR CUSTOMER SERVICE!!!! If they still don't budge tell them that one of your agents was burnt by the back of the phone and they will see your lawyer soon and see if that helps you.
