Appreciate any feedback and suggestions that would help me resolve error thats being encountered by the PBX Option 81C. The situation is that everytime I would close the face cover of my IPE shelf, "ring 0" state would go to "NONE" and "ring 1" would indicate "full". I'm sure that all fibre cables do not even touch the cover. And I do not get any fiji errors if the IPE shelf is left uncovered. I have Option 81 release 5.0. Any suggestions that would help is greatly appreciated.
