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

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.
port of multiple interconnect switches.
4.
Port 48 is used for the interconnect to the Root Console Switch (ProCurve 2650 or ProCurve

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,

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).
