Install a drive shelf for a hot-add
Steps
1. If you are hot-adding one shelf using one set of RoCE capable ports (one RoCE capable I/O module) on

Otherwise, go to the next step.
This step assumes that you installed the RoCE capable I/O module in slot 3, instead of slot
7, on each controller module.
a. Cable shelf NSM A port e0a to controller A slot 3 port a.
b. Cable shelf NSM A port e0b to controller B slot 3 port b.
c. Cable shelf NSM B port e0a to controller B slot 3 port a.
d. Cable shelf NSM B port e0b to controller A slot 3 port b.
