What is the proper way to remove a SCC from a stack of cabinets, I have an EPN that is a stack of three SCC which is more than I need at that location. I'd like to remove the C cabinet from the stack, but not make a mess of it.

Assuning that this is an "si" it's pretty easy:

1) Remove ALL translations in the "C" cabinet
2) SAVE TRANSLATIONS
3) Power down ALL cabinets
4) Remove the back covers of both "B" and "C" cabinets
5) Remove the TDM/LAN Bus cable between "B" and "C"
6) Move the TDM/LAN Bus Terminator from "C" to "B" ... will go where you removed the cable in step 5
7) Button up the back of "B" and restore power to "A" and "B"

IMPORTANT NOTE ON STEPS 5 and 6: The pins on the backplane that the TDM/LAN Bus cable and terminators connect to are not trivial items. Great care should be taken to make sure that you do not bend or break any of them ... and they bend and break veery easily if you're not careful. Line up the connectors carefully and wiggle the connectors GENTLY until they are fully seated. UNDER NO CIRCUMSTANCES SHOULD YOU FORCE THE CONNECTORS INTO PLACE. If they do not go easily then you're probably not lined up correctly and could be causing yourself a world of heartache.

OBSERVATION: There's really no need to remove the "C" carrier unless you plan to re-deploy it to another location. If you're bored and simply have nothing better to do then do yourself a favor and resist the urge to remove the cabinet. Consider the consequences should you have an "accident" ... not likely, but you always need to give some weight to the possibility

It's a G3V10, yes I'm removing the cabinet to deploy in another location.

ahays

Well, as long as it's a G3si V10 you'll be OK. If it's a G3r or an S8xx0 platform with SCC1 cabinets then there's an additional step.

Sorry about that yes it is indeed a G3r

ahays

Since this is a G3r then the SCC stack cabinet number MUST be 02 or greater since cabinet 01 MUST be an MCC by definition. The "si" is smart enough to sense it's environment. With the G3r you have to tell it about very single cabinet and carrier.

Therefore, add the following step between 1 and 2 above: "change cabinet x" , remove the "C" carrier and then save the form (x is the SCC cabinet stack number).

Additionally, when you power down the cabinets you'll only need to power down the three carriers in the SCC stack.

Another point about the TDM terminator. When you seat it, make absolutely certain that you are not off a row either vertically or horizontally. It will insert easily so do a visual inspection using a flashlight before restoring power. Make sure the orientation is the same as it was in the other cabinet. Do not turn it upside down.

You can move an SCC carrier between a G3si and a G3r with no problem, just follow the steps that Al already explained.
