HP XC System Software Hardware Preparation Guide Version 3.0

Ports 1–10, 13–22, 25–34, 37–42
Starting with port 1, the ports are used for links from Branch Administration Switches, which
includes the use of trunking. Two-port trunking can be used for each Branch Administration Switch.
NOTE Trunking is restricted to within the same group of 10 (you cannot trunk with ports 10 and
13). HP recommends that all trunking use consecutive ports within the same group (1–10, 13–22,
25–34, or 37–42).
Starting with port 41 and in descending order, ports are assigned for use by individual nodes.
Ports 11, 12, 23, 24, 35, 36 are unused.
For size-limited configurations, the ProCurve 2824 switch is an alternative Root Administration Switch.
If you are using a ProCurve 2824 switch as the switch at the center of the Administration Network, use
Figure 2-6 to make the appropriate port connections. 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 2-6 enumerate the following:
1. Port 22 is used for the administration port of the head node.
2. Port 23 is used as the interconnect to the Root Console Switch (ProCurve 2650 or ProCurve 2626)
As a result of performance considerations, and given the number of ports available in the ProCurve 2824,
the allocation order of ports is as follows:
Ports 1–10, 13–21
Starting with port 1, the ports are used for links from Branch Administration Switches which can
include the use of trunking. For example, if two port trunking is used, the first Branch Administration
Switch uses port 1 and 2 of the Root Administration Switch.
Note
Trunking is restricted to within the same group of 10 (you cannot trunk with ports 10 and 13). HP
recommends that all trunking use consecutive ports within the same group (1–10 or 13–21).
Starting with port 21 and descending, ports are assigned for use by individual root nodes. A root
node is a node that is connected directly to the Root Administration Switch.
Port 23 can be one of the following:
Console (or line monitoring card) for the interconnect
Interlink to a separate switch (10/100) containing multiple interconnect consoles
Port 24 is used as the interconnect to the Root Console Switch
Ports 11 and 12 are unused.
Root Console Switches
The following switches are supported as Root Console Switches for the Console Branch of the Administration
network. The Console Branch functions at a lower speed (10/100 Mbps) than the rest of the Administration
network.
