IP office slots 3 and 4 stop working 1

[RodneyMcSnow]

Existing IP office 500 V2 running 8.79 firmware
Slot-1 combo card v1
Slot-2 combo card v1
Slot-3 Digital 8 with ATM4
Slot-4 Digital 8 (trying to put new card here)

Whenever I try to put a new digital eight card in slot for when I power the system back up slots three and four have no dial tone and no audio speech path on any of the phones.
If I switch the cards and put the working card in slot for and the new card in the slot three power back up I get the same issue
Replace the system chassis last night same problem.
If I put the new card in the slot 4 only and no card in the slot three works fine, And if I put the old Card in slot 4 and no card in slot three works fine.
Upgraded the firmware again to same 8.79 Just to make sure all the cards are the same revision same problem.
No errors show up in system monitor or system status monitor. Anyone have any thoughts??

Suspect ATM4 card is faulty. try both without the ATM card.

To hear the word 'No' in German, press 9.

I have run into this issue before once and we deleted the 3rd and 4th card from the control unit and then rebooted the system without the cards in and then rebooted the system with the cards in and when it came back up it resolved the issue.

Actually yeah i had this issue once. Was around 9.1 time.
The cards kept coming back.
