Power Supplies......anyone else noticed increasing failures?

[amriddle01]

Hi all, I was just wondering if anyone else had experienced power supplies failing more frequantly than they used too. We have had 4 or 5 in the last 6 months and it appears it's not just the external ones for expansion modules, we have had to send 2x New from the box 500's back as when we powerered them up you could hear a crackling from the built in PSU. I wonder if Avaya are saving costs by going cheap on these!

I have had four IP 500 go down in the last 5 months, one was down to the customers UPS going faulty but all had to be swapped out and sent for repair.

I asked the pre sales from Avaya about this but they refused to be drawn in.

Worrying!!!

We always programme them up then leave them running in house for a good week at least, one of these failures was off a UPS..I think they are simply going cheaper on the components and now we pay the price....buy cheap buy twice.

We have had 3 go faulty out of about 20 installs.

I did open the last one up and noticed the older IP500's have a 2 amp fuse in the PSU and newer ones have a 3.15 amp fuse in. I did try change the fuse but it blew that straight away.

Ours was the first one we got (about 2 weeks after 4.0 GA) and has never had any issues.

the ones we have had go were bought between Aug-Oct 07.

I also do let the system boot fully, then unplug the PSU's, and replug them in forcing them through multiple full power down, and up cycles to make sure they are all solid the first day.

I used to smoke cigs so every smoke, or other break on the way out, and the way in from the break I would cycle the AC on the PSU's.

I just believe you should not install untested hardware in new systems.

I haven't had any problems yet.

It sound a bit scary, but when i look at the posts, there are vendors, programmers and technical users.

Are those vendors talking over the same units as the programmers/technical users? It could of course be the same unit.

Greetzzz..Bas
