2.3.1 Root Administration Switch
The Root Administration Switch for the Administration Network of an XC system can be either
a ProCurve 2 848 switch or a ProCurve 2824 switch for small configuratio ns.
If you are using a ProCu rve 2848 switch as the switch at the center of the Admin
istration
Network, use Figure 2-3 to make the appropriate po rt connections. In the fig
ure, whit e ports
should not hav e connectio ns, black ports can have connections, and ports wi
th num bered
callouts are used for specific p urposes, described after the figure. Gray-
colored ports are
reserved for fut ur e use.

1 Port 42 must be used for the adm in istratio n port of the head node.
2 Port 47 can be one of the following:
• Connection (or line monitoring card) for the interconnect
• Interlink to a separate switch (10/100) containing multip le interconn ects
3 Port 48 is used as the interconnect to the Root Console Sw itch (ProCurve 265 0 o r
ProCurve 2626)
The ports on this swit ch must be allocated as follows for maximum performance:
• Ports 1–10, 13–22, 25–34, 37–42
