Procedure
1. In the base rack and each storage rack, connect an Omni-Path fabric data cable to the lower Omni-Path
switch (OPA0 in the diagrams) (available ports listed above), and then to the customer core switch.
2. In the base rack and each storage rack, connect an Omni-Path fabric data cable to the upper Omni-Path
switch (OPA1 in the diagrams) (available ports listed above), and then to the customer core switch.
3. In each storage rack of a multi-rack system, connect a Cat 5/6 Ethernet cable to the lower Ethernet switch
(SW0) (available ports listed above). Connect the other end of the cable to the lower Ethernet switch (SW0) in
the base rack.
4. In each storage rack of a multi-rack system, connect a Cat 5/6 Ethernet cable to the upper Ethernet switch
(SW1) (available ports listed above). Connect the other end of the cable to the upper Ethernet switch (SW1)
in the base rack.
5. In the base rack, connect a Cat 5/6 Ethernet cable from the NIC card, SMU node 0, NIC 5 to the local
network.
6. In the base rack, connect another Cat 5/6 Ethernet cable from the NIC card, SMU Node 1, NIC 5 to the local
network.
