HP XC System Software Hardware Preparation Guide Version 3.2
Allocate the ports on this switch for consistency with the administration switches, as follows:
• Ports 1–10, 13–21
— Starting with port 1, the ports are used for links from Branch Console Switches. Trunking
is not used.
— Starting with port 21 and in descending order, ports are assigned for use by individual
nodes in the utility cabinet. Nodes in the utility cabinet are connected directly to the
Root Administration Switch.
NOTE: There must be at least one idle port in this set to indicate the dividing line
between branch links and root node administration ports.
• Ports 11, 12, 23, and 24, are unused.
3.3.7 Branch Administration Switches
The Branch Administration Switch of an HP XC system can be either a ProCurve 2848 switch or
a ProCurve 2824 switch.
Figure 3-9 shows the ProCurve 2848 switch. In the figure, white ports should not have connections,
black ports can have connections, and ports with numbered callouts are used for specific purposes,
described after the figure.

The callouts in the figure enumerate the following:
1. Port 45 is used for the trunked link to the Root Administration Switch.
2. Port 46 is used for the trunked link to the Root Administration Switch.
Allocate the ports on this switch for maximum performance, as follows:
• Ports 1–10, 13–22, 25–34, and 37–44 are used for the administration ports for the individual
nodes (up to 38 nodes).
• Ports 11, 12, 23, 24, 35, 36, 47, and 48 are unused.
The ProCurve 2824 switch is shown in Figure 3-10. In the figure, white ports should not have
connections, black ports can have connections, and ports with numbered callouts are used for a
specific purposes, described after the figure.
