Two different setups all together.
with 7-mode & cDOT, the HA interconnect is inside the chassis. No cables needed.
With cDOT, the switchless cluster refers to the private backend cluster network (typically a 10gig network) that runs on the NetApp 1610 switches or Nexus 5Ks
So, in your case, no external cables should be necessary.

Hello, I've currently got a FAS3240 HA pair (with each controller in its own chassis). I am swapping the heads with a FAS8020 HA pair. This is 7-mode 8.2.x.
With the current 3240's..there are a cluster interconnects that runs between c0a and c0b on both controllers.
The new 8020 is a HA pair in one chassis. Are cluster interconnects required ?
The Installation and Setup Instructions guide shows it differently for cDOT and 7-mode..
For cDOT is says to connect e0a to e0a and e0b to e0b for the cluster interconnect. This is listed as a "switchless cluster" for cDOT. (no mention of 7-mode here)
For 7-mode and cDot for a "switched HA configuration", it has e0a and e0b for both heads going the upstream switches.
The guide I'm talking about is at:

Install Hardware (blue 2) step 2.2
I am not planning on using e0a or e0b for networking at all. The purchase did not come with any cables that will work between these ports.
Thanks. Paul
