A "friendly competitor" just accepted/repo'ed an IPK in consideration of a couple K owed for cabling and MAC work. Knowing my NEC IPS background, he asked me to look at it.

He had defaulted programming by disconnecting the processor battery during removal. I was able to fire it up and got a display on a DTerm right away. All cards appear to be programmed and working, and Vmail answers when called, responds correctly, etc.

My question: In S3, there is an ESIB (8) card with two RJ-45s. I'm familiar with ESI-8, but haven't worked on the ESIB. My understanding is that the two RJ-45s provide an additional 8 ports.

The problem is that I can't find those ports in programming. Existing physical ports are 01-24, voicemail is 24-27. There is an old cutsheet in the box showing extensions and users for ports 28-35. LK4-10 does not list those ports.

The ports do not come up for a DTerm (series E or Series I).

Is there a special memory block for the additional ports, or is there a trick to make the IPK recognize the expansion card?

You said he defaulted the programming by disconnecting the processor battery and you were able to call voice and it works, If this was a IPK calling voice mail would not have worked. It sounds like you have a IPK II, removing the battery will not default the system data, only the time and date.
What's in slots 1 and 2?

Sorry I know what's in slot 1 (ESI), what is in slot 2?

ESI8 in S1, nothing in S2, ESIB(8) in S3.

Station numbers appear to have changed from the cutsheet, and he says that it used to have station names (4-18) but it does not now.

Also, when he first got it, the ESI8 in S1 had been placed in the AP slot, so someone had screwed around with the system.

If it's an IPK there's a chance it only set that slot to be 8 ports when you defaulted the switch.

Check program 7-1 to see how the slot is assigned.

You might have to manually programm the cards in the slots to get them to assign correctly.

Just plug a phone into the front of the card to check it.

A phone on the front does nothing. So I'll need to verify in 7-1 that it's an ESIB-8.

Thanks! :wave:

ESI- 16

It does show in 7-1 as an ESI-16. Silly question: Since there is nothing in S2, could the IPKII have assigned those port numbers (9-16+17-24) to the ESI-16?

I do show 24 ports with only the two ESI cards, but the RJ45s will not boot a Dterm. My understanding was that this card could not use the backplane, which is why there are RJ-45s on the front.

S1 - ESI-8
S2 - NON
S3 - ESIB-16
S4 - COID
S5 - COID
S6 - COID
S7 - NON
S8 - VMS (4)

If you're using memory block 7-1, you are working on an IPK, not a IPK II.

Okay.

So how would the port numbers show up, and on IPK or IPK II, is there a reason why the two RJ45 connections would not bring up a Dterm? Is there another memory block associated with this card?
