Otherwise, go to the next step.
a. Cable shelf NSM A port e0a to controller A port e0c.
b. Cable shelf NSM A port e0b to controller B port e0d.
c. Cable shelf NSM B port e0a to controller B port e0c.
d. Cable shelf NSM B port e0b to controller A port e0d.
The following illustration shows cabling for one hot-added shelf using one set of RoCE capable ports
on each controller module:
2. If you are hot-adding one or two shelves using two sets of RoCE capable ports (on board and PCIe card
RoCE capable ports) on each controller module, complete the following substeps.
