2.3.2.2 ProCurve 2626 Switch
A ProCurve 2626 switch can be used as a Root Console Switch for the Console Branch of the
System Admin istratio n network. The ProCurve 2626 switch is shown in Figure 2-6. In t he
figure, white ports should not have co nnection s, black ports can have connections, and ports
with numbered callouts are used for specific purposes, described after the figure.

1 Port 22 mu st be used for the console port of the head node.
2 Port 25 is reserved.
3 Port 26 is th e Gigabit Ethernet link t o the Root Ad mi n istr ati on Switch.
The ports on this switch must be allocated as follows for consistency with the administrat ion
switches:
• Ports 1–10, 1 3–2 1
- Starting with po rt 1, the ports are used for links from Branch Console Switches.
Trunking is not used.
- Starting with po rt 21 and in descending order, ports are assigned for use by individual
root nodes. A roo t node is a node that is connected directly to the Root Admin istration
Switch.
______________________ Note ______________________
There must be at least one idle port in this set to indicate the dividing line
between branch links an d root node administration ports.
• Ports 11, 12, 23, and 24, are unused.
2.3.3 Branch Administrat ion Switch Ports
The Branch A dministration Switch of an XC system can be either a ProCurve 2848 sw itch or
a ProCurve 2824 switch.
Figure 2-7 shows the ProCurve 2848 switch. In the figure, white ports should n ot have
connections, black ports can have connections, and port s w i th numbered callouts are used for
specific purposes, described after the figure.
