Thanks for your time and knowledge. I am trying to understand how bypass mode works in terms of cross connection.
Bypass mode: network relays cross-connect the two RJ45 connectors electrically thus creating an extended Layer 1 network
Let us focus on one connection COM1 --- 3560 --- ELFIQ (Link Balancer) ---- ASA.
Basically ELFIQ will be a bypass mode when power is gone.
The engineer told me that I have to put cross cable between ELFIQ and ASA5505 only which is "2" cable from below diagram.
So, it will be
COM1 ------(Straight)----- 3560 -----(straight)------ ELFIQ (Link Balancer) -----(cross)--- ASA.

And he told me also that if there is no switch (in future). I need to put both cables as cross cables.
COM1 ------------- (Cross) ------------------ ELFIQ-------------- (Cross) ------------------ ASA5505
I couldn't see any consistency from this bypass works because case 1 (with switch) and case 2 (without switch)
Is my understanding right like below?
case 1: straight - straight - cross : cross
case 2: cross - cross: straight.
