The callouts in the figure enumerate the following:
1. Uplinks from branches start at port 1 (ascending).
2. 10/100/1000 Base-TX RJ-45 ports.
3. Connections to node administration ports start at port 21 (descending).
4. Port 22 is used for the administration port of the head node.
5. Dual personality ports.
6. Port 24 is used as the interconnect to the Root Console Switch (a ProCurve 2650 or ProCurve
2626 model switch).
As a result of performance considerations and given the number of ports available in the ProCurve
2824 switch, the allocation order of ports is:
• 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.
• Ports 11 and 12 are unused.
• Port 23 can be one of the following:
— Console (or line monitoring card) for the interconnect
— Connection to the Interconnect Ethernet Switch (IES), which connects to the management
port of multiple interconnect switches.
• Port 24 is used as the interconnect to the Root Console Switch
3.3.6 Root Console Switches
The following switches are supported as Root Console Switches for the console branch of the
administration network:
• “ProCurve 2650 Switch” (page 52)
• “ProCurve 2610-48 Switch” (page 52)
• “ProCurve 2626 Switch” (page 53)
• “ProCurve 2610-24 Switch” (page 54)
