ACS station port 11 has static

I have a customer with a Partner ACS R6.0 with static on just one station port. Is that an indication of the module failing?
Thanks in advance.
 
Hi ontime,
Try to plug the phone directly into the station port before condeming the card. Sometimes jacks and cables can cause the same problem.
If the noise is still there, it's the card (port). This can happen, but is not extremely common with the new cards.

Within 6 months of deployment, I had a station port (#11) fail on a Partner ACS 6.0. Thankfully, I had a spare processor onsite and simply swapped it out and had the still-under-warranty processor replaced.

If this is a common problem, I hope that Avaya and Celestica, the company that Avaya contracts to manufacture the Partner ACS, take steps to reduce the frequency of this type of failure.

Another early failure, and I may be forced to switch to the Merlin Magix, even though it would be overkill for our application.
 
Hi Dexman,
I haven't seen this to often. Lucky I guess. I do take a spare processor with me as I've seen a mix of strange faults.
A Magix is out of the price range for most Partner customers, or that's what I'd sell & install.

Hey Chris!

I crunched the numbers, and the cost of a suitable Magix system, would not be too out of reach, except for the cost of the voicemail system. Shelling out $6,600 for 2 voicemail modules, [1 working and 1 spare], would be a large outlay of capital.

It just surprises me that our Merlin 410, which is on standby for fall-back purposes, has never had a single problem since it was installed years & years ago, but the Partner ACS developed a problem within 6 months. [ponder]

Hi Paul,
That can happen, but I've installed tons of them with no problems for years. Many of them are full to capacity. I do make sure I install them properly, in a cool location (normally the server room). I use CAT-5e these days. Even the GAP stores are still okay. Full 5 slot carriers, the old ones, typically in the power panel area. No problems .. yet.
Normally my problems are straight out of the box. For reliability, you just can't beat the Magix. I still have faults out of the box with these. The only thing more reliable than a Magix are the Eon switches (new ITT 3100's).

Hey Chris!

It would be unrealistic for 100% of all Partner processors to have 0 failures, but I've already had the disk drive on a refurbished Partner Mail VS 4.1 get loud and then malfunction, followed by the port failure on the ACS 6.0.

I did change from a 2 card carrier to the latest 5 card carrier and then mounted 2 fans above the carrier to create airflow. The door to the closet is left open 24/7. (No security problems created by doing this.)

The system is located below grade, in a closet under a stairway. The temp rarely goes above 80*f but the humidity can get up into the 70% range. I am considering purchasing a dehumidifier next spring and placing it outside the closet. This install is in a church in the Boston area so installing air conditioning for the closet and running it 24/7 during the summer would be cost prohibitive. Cool air does filter in from another part of the building where a central air conditioning system does run on a limited basis.

But, so far so good. The system is behaving itself and nobody has any complaints. [sunshine]

Hi Dexman,
Sorry for the delay in response. I was in England 'till last night.
The two slot carrier is death to the processor. The best thing you did was to install the new 5 slot carrier. Keep in mind that the hotter the system runs, the more faults you will have. I moved the phone system from the boiler room in a church to the accountants office (air conditioned too!). No failures since that time. If this area will be hot, consider running 25 or 50 pairs to a better location and move the system there. Crossconnect bact to the old MDF and you are in business. Do watch for mice.

Hi Chris!

Hope you had a great vacation. [smile].

The current location is probably the best as it has the most stable temperature, is easy to access and is not in a very busy area.

Sadly, none of the offices are climate controlled 24/7. The wing was added in the 1950s and the large windows and doors are not energy efficient, so trying to maintain a constant temp would push the church's energy costs through the roof.

With the 2 fans mounted above the carrier, I hope that port failures, caused by thermal problems, will be reduced.

Having only a Rev 6.0 procesor in slot #3 and a Partner Messaging R6 in slot #1, heat generation should be minimal and there is space for air flow around the modules.

I may be asked to add a 308 or a 012 expansion module in the not too distant future, and that would be all the capacity that the church would ever need to handle required desk phones as well as a pending door phone.

Thank you again Chris for the advice on changing to a 5 card carrier!

Hi Paul,
Well, it will be okay. The fans are not needed yet. Possibly when the box is near full.
Another thing that helps is harnessing the system wiring. I make up harnesses for each card to BIX (Canadian eh), 110 will be fine although I dislike the AT&T ones. 66 blocks are always the last choice for me. This makes the installation neat and allows air flow from the bottom. Don't forget to use a UPS if you can budget for it. This may save the system in a storm. Sounds like you have a good installation now.
-Chris
 
Hi Chris!

The UPS was the first on the option list. It provides reserve power for the Partner ACS, AT&T 410, Music on Hold player and a 4 port Internet router. The church already suffered a 90 minute commercial power failure but all systems kept right on humming. [thumbsup2]

110 blocks were first used for the ACS as well as the back-up 410, but later switched over to separate 12 position RJ-48X jack strips. The cables leading to the station jacks are punched down on the rear of the strips and the cables from the station ports on each system are plugged into the jacks on the front. I left room under the 5 card carrier for air flow to help dissipate heat from the 2 cards.

The level of cable marking, jack labeling, cable layout and System Planner documenting will make it easy for any CPE technician to understand how the system was installed and programmed.
