The Mellanox 36-port switch is cabled sequentially. Start with the lowest node cabinet number, lowest node and end with the highest node cabinet number, highest node. The network uses the Mellanox InfiniBand Dual 56 Gb adapter in the node slot 5 with port 1 connecting to network 0 and port 2 connecting to network 1.
- Begin with one rack with 18 nodes or less.
- Add expansion racks, cabinets 6 and 9 (no switches).
- For intra-rack cabling in cabinets 1, 3, 4, 5, 7, and 8, see InfiniBand Node-to-Switch Cabling for Cabinet 1 (36-Port Switches).
