I have Sup-2 in slot 1 and 2 with active and standby in 6509 NEB-A chassis.
Now, if i replace sup-2 with sup720 i have to put in slot 5 and 6 where i have some line cards.
Can some body help me to understand why sup720 need to be put in slot 5 and 6 , if i'm going to use same chassis ??????
Thanks in advance.
