HP XC System Software Hardware Preparation Guide Version 3.2
The callout in the figure enumerates the following:
1. Port 22 is used for the link to the Root Administration Switch.
Allocate the ports on this switch for maximum performance, as follows:
• Ports 1–10 and 13–21 are used for the administration ports for the individual nodes (up to
19 nodes).
• Ports 11, 12, 23, and 24 are unused.
3.3.8 Branch Console Switches
The Branch Console Switch of an HP XC system is a ProCurve 2650 switch.
The connections to the ports must parallel the connections of the corresponding Branch
Administration Switch. If a particular node uses port N on a Branch Administration Switch, its
management console port must be connected to port N on the corresponding Branch Console
Switch.
Figure 3-11 shows the ProCurve 2650 switch. In the figure, white ports should not have
connections, black ports can have connections, and ports with numbered callouts are used for a
specific purpose, described after the figure.

The callout in the figure enumerates the following:
1. Port 50 is the link to the Root Console Switch.
Allocate the ports on this switch for maximum performance, as follows:
• Ports 1–10, 13–22, 25–34, 37–44 are used for the console ports of individual nodes (up to 38
nodes).
• Ports 11, 12, 23, 24, 35, 36, 45–49 are unused
3.4 Interconnect Connections
The high-speed interconnect connects every node in the HP XC system. Each node can have an
interconnect card installed in the highest speed PCI slot. Check the hardware documentation to
determine which slot this is.
The interconnect switch console port (or monitoring line card) also connects to the Root
Administration Switch either directly or indirectly, as described in “Root Administration Switch”
(page 40).
You must determine the absolute maximum number of nodes that could possibly be used with
the interconnect hardware that you have. This maximum number of ports on the interconnect
switch or switches (max-node) affects the naming of the nodes in the system. The documentation
that came with the interconnect hardware can help you find this number.
