IP500 power supply failures... 2

thread940-1646782
Hi,
I know this is an old thread I'm referencing, but I have an ongoing problem with the power supplies for the IP500.
We have a base of aging V1 IP500's and I'm getting a fair number of blown power supplies, which, OK would be a pain, but manageble if I could get spares... which since we have been assimilated by a massive corporation, is painful.
So, for my sanity's & customers sake, I'm looking at trying to repair these things. (used to do a bit of hifi repair work..)

amriddle01 mentioned it's the thermistors that go phut, anybody else had any joy fixing these things, any common part failure found???

I know it's a long shot, but otherwise I just have to suck it up and take the corporate line.... stats are more importamt than customers.

Thanks,

The solution is mainly to get a new power supply. Good luck with that. But the real solution would be just to swap with another unit. Save the time and hassle of trying to get the blown power supply back up and running.

An IP Office these days costs less than the pissing around to get the PSU Sorted.

I agree, it is cheaper to just purchase a new (leftover) model on ebay, just saw one retail for $375.00 US dollars, I believe it would cost more for the time involved as well as the repair than just purchasing a new one.

Totally agree, popping a new unit in would be the simpler solution... if it weren't for the bean counters.. & they would never, ever get the paperwork sorted to buy from eBay..

But, when it takes 48 hours now to get a flipping unit to site, once it's been authorised that is, from wherever the stores are now.. while the customer is hitting me round the head, it would probably be easier to buy the individual components and build the PSU's myself
You may laugh, but I have sites where the customers are buying their own spare units off eBay to speed things up.

I knew it was a long shot, just hoping someone might say "Oh, it's usually the 220uf cap by the smaller copper heatsink that explodes in a shower of Avaya-ness all over the insides"

Thanks anyway!

Our tech repairs them, but as he said... If you have the know how/skills to repair and test them you should also have the ability to find what failed in the first place

I had an IPO 500v1 power supply go bad, so I tried replacing the power supply with one from a V2 cabinet and it seemed to work. (so far)

Has anyone else done this, or did I create a ticking time bomb!

Thanks.

You may be OK, but if it does burst into flames and take the building/people with it you're right in the firing line legally

Totally agree, popping a new unit in would be the simpler solution... if it weren't for the bean counters. doesn't make sense, what does down time cost the company? I am guessing it is a lot more that just to replace the box, bean counters have no common sense but as my dad says (you can not teach common sense son)

if you are in the maintenance business with this number of customers then surely it makes sense to have 1 or 2 maintenance spares that can be shipped to site quickly then have the faulty unit repaired & returned to stock.

Perhaps the bean counters need to be reminded of the commitments in your maintenance contracts & the potential cost form a disgruntled customer.


A Maintenance contract is essential, not a Luxury.
Do things on the cheap & it will cost you dear

That is happening with me right now. A customer has taken out a power supply, combo cards (2), and I finally told them to put a UPS on the system.

So far, so good.

I did actually have a new, out of the box IP Office Control Unit where the power supply worked fine for 2- 3 weeks while I turned it up, and when it got mounted on the wall by the installer, it died.

There is a fuse inside, on the power supply, and yes I know this voids warranty, but the customer had to get up and running. Since I didn't have a spare power supply in my back pocket, did the next best thing.

Regards.
