2. If you are hot-adding one or two shelves using two sets of RoCE capable ports (two RoCE capable PCIe
cards) on each controller module, complete the applicable substeps.
This step assumes you installed the RoCE capable PCIe cards in slot 5 and slot 3.
Shelves Cabling
Shelf 1
These substeps assume you are beginning the cabling by
cabling shelf port e0a to the RoCE capable PCIe card in slot 5,
instead of slot 3.
a. Cable NSM A port e0a to controller A slot 5 port a.
b. Cable NSM A port e0b to controller B slot 3 port b.
c. Cable NSM B port e0a to controller B slot 5 port a.
d. Cable NSM B port e0b to controller A slot 3 port b.
e. If you are hot-adding a second shelf, complete the “Shelf 2” substeps;
otherwise, go to step 3.
Shelf 2
These substeps assume you are beginning the cabling by
cabling shelf port e0a to the RoCE capable PCIe card in slot 3,
instead of slot 5 (which correlates with the cabling substeps for
shelf 1).
a. Cable NSM A port e0a to controller A slot 3 port a.
b. Cable NSM A port e0b to controller B slot 5 port b.
c. Cable NSM B port e0a to controller B slot 3 port a.
d. Cable NSM B port e0b to controller A slot 5 port b.
e. Go to step 3.
The following illustration shows cabling for two hot-added shelves:
