Avamar Internal Switches

Hi,

Where can I find the hardware Ports layout for the Internal switches (Gen4s)? All I could find is (Mgmt) port 24 on bottom switch that you supposed to connect to your laptop. and, of course any of the Node's Nic2(eth1)&Nic4(eth3) that are redundantly connected to switch A &B. Is there a scheme design of which ports one supposed to use? i.e. node0 eth1 => to port 0 SwitchA, Node0 eth3 => port0 on SwitchB, etc....?

It might be a newbie question, but I could not find any doc describing this anywhere.  

thanks.
