12.1.2 DC2 and DC4 Ports and Cabling

The DC2 and DC4 drive cages contain two FCAL modules for connecting the drive cage to the

controller nodes. The left-hand FCAL module has two ports: A0 and B0, and the right-hand

FCAL module has two ports: A1, and B1.

Fibre Channel cables connect the Fibre Channel ports in the drive cage to the ports on the

controller nodes. Each cable is labeled to indicate the ports it uses (Figure 12-3):
