Configuring a 2+1 Configuration with 12 S2 FCs
The following figure shows two line card chassis (LCC0 and LCC1) connected to one fabric card chassis
(FCC0) that has 12 S2 FCs installed. The advantage of installing 12 S2 FCs cards instead of 6 S2 FCs cards
is that only half of the available S2 ports are used. This allows up to two additional LCCs to be added later
without having to re-cable the initial 2 LCCs.
