slots and cabinets in Option 11

[coniglio]

i am going to be talking someone through installing an analog card in one of my remote PBXs and want to make sure I'm 100% correct in what I'm asking him to do:

037 * (does this refer to the FOURTH cabinet, slot 7?)
038 * (does this refer to the FOURTH cabinet, slot 8?)
039 *
041 * (does this refer to the FIFTH cabinet, slot 1?)
042 *
043 *

And whatever slots/shelves these are, can i put an analog card in any of them? I kind of need an immediate answer. thanks for your help.

You are correct. I would hope your slots are actually numbered to match that. I looked at my second cabinet and it is numbered 11-20. I would hope if I needed a third cabinet, I could get it with 21-30 already numbered.

how come there is a zero in front? i can imaging i could have a 9-cabinet option 11! generally speaking the FIRST cabinet is ZERO, the SECOND cabinet is ONE, and so on?

The 0 slot is where the CPU resides. Slot 10 is for Meridian Mail.

Each Option 11 cabinet has 10 slots, and you can have up to 5 cabinets. The zero doesn't really mean anything.. Nortel likes to use zeros. Just think of the first slot in cabinet 1 as 1, in cabinet 2 as 11, and so on. Yes, you can put an analog or digital card in any slot (1-10). It is good practice to put line cards with line cards and trunk cards with trunk cards, but that is more of a "housekeeping" thing.

Special note for future reference if ever applicable - original hardware installers should number the cabinets with supplied labels as cabinet 0 (slots 1 to 10), cabinet 1 (slots 11 to 20), cabinet 2 (slots 21 to 30), etc. The reason i say this is that in some of the installs i have seen, the third cabinet is not always cabinet 2 (slots 21 to 30) but cabinet 3 (slots 31 to 40). On the 5-cabinet Option 11C platform, the fiber daughterboards (DB) are equipped with two sets of fiber ports to accomodate two cabinets. The first DB gives you cabinets one & three (11 to 20 & 31 to 40) and the second DB gives you cabinets two & four (21 to 30 & 41 to 50).

Good point, thank you.
