NEC NEAX 2000 IPS

[Zero6]

Hi all,

I have an issue with NEAX 2000 ips in which no internal, outgoing, incoming calls can be made.
THe pbx is connected to 2 other pbx of NEAX 2000 ips, so in total they are 3 coupled with each other.
If not mistaken the primary obx and secondary pbx are working, except for the third one.
I replaced all 8 analogue cards with new ones, but none of them are working.
So I took the old card and replaced them in the secondary and primary and the started working.
Does this mean the 3rd pbx mother board is defective, because I rebooted them all but nothing happens and only the power light I see is on?!

Also I am new at this IPS2000 but I wanted to know a few things.

1)Is pn-8LCAA cards the same as PN-8LCAK cards?
2)How can I assigned an extension to an analogue card?
3)Is it possible to look up in MATWorX which extension belongs to analogue or digital card, been searching for it but I can't find it.

Thank you in advance

If you swapped out the CPU and it started working, then I'd say the CPU is defective. You do not say if the systems are connected via CCIS. If your CPU is bad, then you have a real problem. You cannot get them from NEC anymore since that system is mfg discontinued and end of life with no support. Any CPU you find must have the proper licensing and a valid IVR registration number for your system to work and for it to connect with CCIS. (US systems).
The 8LCAA and 8LCAK cards are compatible. I believe the -K card adds the ability for caller ID to SLT's.
In MatWorX, run a LENS report. With that in hand you can determine what cards are where.
I hope you have a good database back up.
If you are sure that the CPU is bad, you can try defaulting it. This will lose all of your programming, but in case it's a corrupt database, it might recover.

Hi Belevedere, thank you for replying.

So replacing the third unit with another is not option, if I don't have the correct license and valid IVR registration.
If you know does NEC still create license and IVR for this unit?
I really want to avoid resetting the pbx

If I remember correctly on the main unit I saw 2 or 3 slots open, LT08 -> LT10.
Can the analog cards be used there if so, how can I program it, so the extension can go to the card.

I have been trying to find a documentation on how to use the Mat WorX for this pbx,especially on how to run the LENS report.

Is it possible for you to explain how I can program the extension on the analog cards.
For example I saw LEN 01027, 00008, 01027 etc.
How can I figure out what these LENS mean, and which card they belong too, on which pbx and find the position of them.
Also how to know which wiring as the extension on it.

Thank you in advance

NEC does not offer IVR numbers or licenses for this system anymore.
As for adding a card, I would need to see a LENS report or at lease a bayface layout. Slots 0-7 are 8 port slots, slots 8 on up are 4 port shared with 8 port or AP card slots. The PIMS have 64 ports available. Adding another card and exceeding 64 per PIM will not work.
Shared means you can place 2, 4 port cards in, one in slot 8 and the other in slot 4, 5 + 9, 6 + 10 and 7 + 11. This allowed you to keep 4 port cards from the older IVS and migrate up. I suggest you look for a installation manual for more details. Try

When you say that you have 3 PABXs do you mean there are 3 boxes (PIMs) in the same location? Or do you mean 3 PABXs at different locations? There is a big difference as PIMs look the same but if it is a group of 3 PIMs, only the first has a CPU.

If this is one system consisting of 3 PIMs,then you might just have a bad power supply in the 3rd PIM. Do not judge the condition of the power supply by the LED's. You need to use a digital multi-meter and measure the voltages being supplied to the back plane. I usually remove the cards in slot 0 + 1 to gain access to the plug that connects the power supply to the back plane. Push the meter probes into the back end of the plug while it is still plugged in. You are looking for 5 vdc and 27 vdc. There is also a plug with 3 wires in it. That is the ring signal generator for analog phones. That is not what you should be testing.
