If you've removed processor options, then you will
have to change the
jumpering on the processor to match.
On an 11/35 (or 11/40), yes, but not on an 11/45. I don't think there are
any jumpers on that set of processor boards. The only thing to be aware
of is that there's a backplane jumper for the NPG line across the KW11-L
slot, which you cut when you fit that (line time clock) card. You should
re-make it if you ever remove the KW11-L
