AUX port on the back of a NTDU14 cabinet 1

[rheine]

Hello all,

I have a release 5.0 site with I believe a NTDU14 cabinet. There was a spare cabinet located at this 1000E site and they were using the AUX port on the back of the cabinet to feed power to a power fail transfer unit. Keep in mind there were no cards plugged into any of the slots within this cabinet.

They had a spare MGC and I configured that card to work in slot 0 of this cabinet. The problem is as soon as I plug an MGC into slot 0 the AUX does not provide power anymore and all of the power fail phones go into power failure.

I tried other cabinets at this site in regards to trying to use this AUX port with the same results it will not power the PFTU. Is this my only option at this point to have the customer purchase a 48VDC external power supply or is there a work around to use the power provided by these cabinets?

Thanks

That MGC card should not be affecting that 48v dc power.

 

[KCFLHRC]

That 48v dc should be connected to the W/BL or BL/W for BRTN and O/W for the -48v dc.

 

[KCFLHRC]

Are they using a QUA6 pftu or a 3rd party like a DEES?

 

[rheine]

We are using a DEES unit...Could that be the issue?

 

[KCFLHRC]

The DEES unit will work fine. I'm guessing they have it wired wrong. The DEES only needs -48v dc from the aux cable which would be on the colors I described. If they have something connected to the W/O on the AUX cable they shouldn't. That is the PFTS lead and is only used with the QUA6 which when a ground is applied there it puts it into PF. So the W/BL or BL/W wires are BRTN and the O/W wire is -48v dc. Those are the one's to connect to the DEES. Also if you have a console make sure the switch on the bottom of it is not thrown to the PFTU mode.

I will verify the wiring. It is odd that it works now plugged into the AUX of that cabinet without the MGC plugged in? I thought that this was odd because we have other locations including another release 5.0 site that migrated from a release 4.5.88 and those AUX ports work fine.

KCFLHRC (TechnicalUser), That wiring still didn't work. I used a meter and I am getting -48VDC from the w/or, or/w pair off that db9 cable going to the aux port. I get nothing from o/w, w/bl pairs. Is the db9 cable possibly wired incorrectly going to the pin connectors?

 

[KCFLHRC]

That pin out of that cable is in the NTP. The W/BL and BL/W is BRTN and the W/O is PFTS and O/W is -48v DC. You should have -48v dc between the W/BL wire and the O/W wire. If you apply a ground to the PFTS lead it will go into PF. That's about all the NTP says. I suppose you could have a bad cable.

 

[rheine]

This is an odd one. I will try and get another cable and will verify how the other sites are wired. They are all DEES PFTU sites...I might need to get the external power supply but this would be the olny location that would have required an external power supply..

I have a release 4.5.88 that sites behind this release 5.0 PBX and I plugged that db9 cable into it's aux port and it didn't work with that cabinet either.

 

[KCFLHRC]

You got something screwy going on. I just tested one of these for you with and without the MGC card plugged in and the -48v DC is constant across the W/BL and O/W wires. My cable has part # NTAK1104-01 and Part # AO371089 on the tag. Hope this helps.

 

[rheine]

Thank you for the test. I was definetly getting the -48VDC on the w/o, o/w not the w/bl and o/w.

I sent an email off to my co-worker who is the DEES PFTU unit king but I have not heard back from him.

I did hook up this DEES unit originally and not sure why I would have used the w/or,or/wh pairs? I generally copy the wiring scheme from our existing sites that work.

I replaced my Aux cable between the PBX and the punchdowns and this issue is solved now. My power cable was not pinned out correctly. I am closing out this thread. Thanks

 

[KCFLHRC]

That is very strange. Good old Nortel quality control. I mean Avaya, sorry!

I just posted another thread related to this same site. I installed an MGC card in slot 12-1 and set this card with the correct IP address. This is what I am seeing:


SRPT077 IPMG[12 1]: Loadware version mismatch detected. Adding to sequential upgrade que
ue.

SRPT210 Reg GRANTED for IP[10.12.90.27] IPMG[12 1] TS[-691737569]

All of the channels are disabled plus the PBX does not see this card. Can I match the loadware in element manager?
