Ports
10/100/1000 Base-TX RJ-45 Ports
Connections to Node Administration Ports
Begin at Port 41 (Descending)
Uplinks from Branches
Begin at Port 1 (Ascending)
The callouts in the figure enumerate the following:
1. Port 42 must be used for the administration port of the head node.
2. Ports 43 through 46 are used for connecting to the Super Root Switch if you are configuring a large-scale
system.
3. Port 47 can be one of the following:
• Connection (or line monitoring card) for the interconnect.
• Connection to the Interconnect Ethernet Switch (IES), which connects to the management port
of multiple interconnect switches.
4. Port 48 is used for the interconnect to the Root Console Switch (ProCurve 2650 or ProCurve 2626).
The ports on this switch must be allocated as follows for maximum performance:
• 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.
