7 Cabling the Interconnect Each model of HP cluster platform has a set of specific port-to-port cabling tables that describe the origin and destination of every link between the interconnect and the cluster nodes. When the cluster is integrated at the factory, the cables are installed and tested. Certain cables are then removed and the cluster racks are packaged for shipping. At the receiving site, installation engineers cable up the system according to a system-specific cabling table. Perform cabling operations in reference to the Cabling Tables and Ethernet Cabling Tables for your model of HP cluster Platform. Cables are labelled for their origin and destination ports when the cluster is assembled at the factory. You can connect cables to a chassis that is powered up and has completed all its initialization steps. This chapter Contains the following information: • 4X InfiniBand port cabling. (See Section 7.1) • Administrative connections. (See Section 7.3) 7.1 InfiniBand Cabling InfiniBand Cables have the following characteristics: Table 7-1 InfiniBand Cable Characteristics Feature Port type Connector type Maximum Cable Distance Minimum bend radius Specification SX, 4X InfiniBand HSSDC-2 60ft (18m) 4-inches (10cm) Figure Figure 7-1 shows the connector head shells for the two different cable models used in HP Cluster Platform.
