Magix phones shorting each other out?

[killbox]

Here's an odd one. I have a customer with a Release 2.2 Merlin Magix. They have a 412 card in slot 1. An 024 card in slot 2. 4 phones are dead! (Seperate cards)

1. I unplug all the phones or reset the system, etc.
2. Start plugging phones in ...

- If you plug the 1st phon in. Then you plug the 2nd in, it shorts out the 1st.
- You plug the 3rd phone in. Then plug the 4th phone in, it shorts out the 3rd.

THE PHONES ARE ON DIFFERENT CARDS.
Bad cabinet?
Bad power supply in cabinet?
1 of the cards is bad?

Thanks,

Since this is a MAGIX, measure the POWER OUTPUTS and see if they are where they should be.

How do you do that?

If this is the problem, replace the cabinet/power supply?

Thanks,

These kinds of problems are a little "tricky" to troubleshoot. You could have a "bad" port, a "bad" phone or perhaps a combination of both and/or a power supply issue. How many phones are connected to each module currently? I would swap out the 4 "suspect" phones - one at a time on each module at a time - with a known good phone. Just take all 4 phones to where you have a good one on the 412 TDL - and swap them out - 1 at a time. If each one works - then the problem is most likely no the phones.

You could repeat the test on the 024 module - again using a known good phone and port.

If the phones pass - then you probably have one or more ports on one or both modules - that are defective - and creating some system-wide problems.

I would test the "suspect" ports - on one module at a time - by plugging a single known good phone into the port a seeing what happens. The remove and repeat for the next port on the module. If the tests pass - plug known good phones in both "suspect" ports - and see what happens. If they both work - and no other phones are affected - remove the test phones from the 412 TDL and repeat the tests for the 024 TDL module one "suspect" port at a time.

If all ports pass - start adding phones to two ports on the 412TDL - and look for effects - if none continue with the 024 ports - if at some point you are back to the initial problem - you probably have a "bad" power supply.

I would suspect the ports as well. I had a similar issue with only one card. The customer was moving around desks and placed the Ethernet cord into the phone jack and the phone cord into the data jack. Completely killed the ports. I actually had the same thing happen on a DS30 on an IPO as well.

...and when all else fails, try a different Amphenol cable on that puppy too . Especially if this was recently installed or moved and new PBX distribution hardware was used. I've had bad 25x connectors 2 times now in the last 4 years that were out-of-box failures.
