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 never had a ps go bad on an IPO. Are you using a ups. We install all of ours on UPS's which enables us to monitor voltage in and out as well as spikes and surges. this may help. also a good surge protector is a life saver in most instances.

Most of our customers will not pay the extra for a UPS, if it is power spikes causing this Avaya should speak to other manufacturers for tips as all of the other equipment on the sites has been fine apart from the IP Office. It is "recommended" to use UPS's, not tough Sh1t if you don't. Power surges and spikes always have and always will occur, and equipment which is expected to be powerered up permanantly as Telephone Systems are should be made very resiliant to such things not having to be protected by third party devices.....or that's what I think anyway!! lol

We had one go about 2 days after we first installed it. Just refusses to power on.
First one i've seen ( only been on the scence 4 months )
 
I have noticed that if you plug in the power cable too slow in to the ip500 it will spark very much
It is better to plug it in the ip500 first and then plug in the other end of the cable in to the power
Or you need to be very quick !

So it's not just us!! Does that mean that the ones which make the noise are just so bad that you can hear it and others are not quite as bad (so quiet) but yet still faulty?....I think so. I will be prepared to change more units out then...Great more disgruntled customers

we have had five systems fail in the last six months. Only one out of the box. Some of them not fail completely.

What has been happening is the system will run fine for a few days to a week and then it will start to reboot. Initially the rebooting will be rare but the incidents of it will speed up until it is rebooting constantly.

Of course it is falling on deaf ears at Avaya.

Please remember to thank preople for their valuable input.
 
We've had 2 systems going down during the in house programming fase. (preparation at our location and not on the customers site).
In the next morning we were more alarmed by the smell of burnt electronics than the IPO not showing any leds.

After these occasions we have accepted the 'burn-in test' phrase that is also used in other branches and try to plan the preprogramming more upfront. This way we can swap a faulty IP500 in time with our BP so we can still make the installation date already set with the customer.

 
1 500 PSU go pop since launch. Not noticed any other problems

I've 2 go...


The PSU looks to be field replaceable, but the difficult bit is getting a spare PSU.


Take Care

If at first you don't succeed, skydiving is not for you.
 
This is getting silly, just had another two go, one 3 month old one 6...I hope Avaya take note and don't just fob it off as normal failure rate.

You guys scare me, I haven't had a PSU go bad so far and will probably regret having this said, we are pretty slow these days and install maybe 1 a week sometimes not even that but like I said we had nothing yet happening with the power units.

I have noticed increasing failures on more than just power supplies
 
Haven't had any Power Supply's go yet. over 20 sites, multiple expansion units.. We use UPS with built in power surge protection.. So maybe the Avaya PS's are a bit sensitive.
 
I've had a couple of external PSUs and one IPO500 that went dead the last 2 months.

Usually releated to powerfailure at the customer, and since the ones that use UPS never had a problem I can't really complain.

Since it's recommended to have UPS it's up to the customer to take the risk.
 
the failure rate for us on the IP500 is a lot higher than the 403/406 and out of last 2 installs we had a PSU faulty and a LAN port not communicating so both required a swop out. The worst PSU's must be the ones used for the IP phones. We shifted an office with 10 IP phones and when we plugged the PSU's in at the new office only 2 worked.They were 3 years old but you would think they would last longer than that!

I like to get the equipment on Thursday day one, install all the boards, and plug it in. I will pull the CFG, and then walk away until day 5.

Monday day 5 I like to test the hardware/ports, then upgrade.

Wednesday day 7 install the hardware on site.

2nd Friday go live day 9.

Most failures happen before Friday close of business, and have overnight replacement by Monday. This gives you until Wednesday to burn in its replacement, and see if the failure fried anything else far enough before the cutover.

My intention is to never install any new hardware without burning it in for 72 hours as this in my experience eliminates 95% of the failures that happen on live systems.

Also, whenever I have a module go down in warranty I would send in the external PSU also in case it was the real issue that took down the module. No sense risking it when there is no good reason why a module should fail by itself unless it is a PSU issue that took it out.
