Cabling a FibreBridge 7600N bridge with disk shelves using IOM12 modules

After configuring the bridge, you can start cabling your new system.

1. Daisy-chain the disk shelves in each stack:
   1. Beginning with the logical first shelf in the stack, connect IOM A port 3 to the next shelf's IOM A port 1 until each IOM A in the stack is connected.
   2. Repeat the previous substep for IOM B.
   3. Repeat the previous substeps for each stack.
2. Power on the disk shelves, and then set the shelf IDs.

   • You must power-cycle each disk shelf.

   • Shelf IDs must be unique for each SAS disk shelf within each MetroCluster DR group (including both sites).

3. Cable disk shelves to the FibreBridge bridges.
   1. For the first stack of disk shelves, cable IOM A of the first shelf to SAS port A on FibreBridge A, and cable IOM B of the last shelf to SAS port A on FibreBridge B.
   2. For additional shelf stacks, repeat the previous step using the next available SAS port on the FibreBridge bridges, using port B for the second stack, port C for the third stack, and port D for the fourth stack.
   3. During cabling, attach the stacks based on IOM12 and IOM3/IOM6 modules to the same bridge as long as they are connected to separate SAS ports.

      Note

      Each stack can use different models of IOM, but all disk shelves within a stack must use the same model.
