The callouts in Figure 2-8 enumerate the following:
1. Port 22 must be reserved for an optional connection to the console port on the head node.
2. Port 25 is reserved.
3. Port 26 is the Gigabit Ethernet link to the Root Administration Switch.
The ports on this switch must be allocated as follows for consistency with the administration switches:
• 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 root nodes.
A root node is a node that is 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.
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 2-9 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 Figure 2-9 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.
The ports on this switch must be allocated as follows for maximum performance:
• 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.
