Hi,

What's the precise GSR-modell ?

To the CSC- and SFC-cards. For the 12x16 modells you can look at it like
this. In a full config you have 3/4 SFC cards and 2 CSC cards. Basically
a CSC is an SFC with a clocking-module added, serving the box with its
local clock. A CSC-card can run as either CSC or SFC. Normally you'll
have the lower-slot # CSC running as active, together with all
SFC-cards, the higher # CSC is running standby.
As soon as you'll have a failure or card-removal on either CSC/SFC the
standby CSC will take over (N+1 redundancy). This is done more or less
hot, you could get a short blip but normally shouldn't. In case of a
failed SFC it should fall back upon replacement and run the CSC as
standby again. In case of a failed CSC I'm uncertain, don't believe it
will fallback, but you'd need to test.

So in case you'd want to upgrade the switch-fabric for e.g. 12016 ->
12416/12816 you could try to do the card-swaps 1:1, not 100% certain if
it'll work though, having a card-mix like that. And since you'd need a
reload after anyway, I'd simply shutdown the box in an outage-window
completely, perform all card-swaps and reboot it again.

Either way, do NOT forget to perform a 'upgrade all all' when finished
with the HW-swaps and after having booted with the final SW-release you
want to run with !!!
