Administrator Passwords on a ProCurve Switch
The documentation that came with your model of ProCurve switch describes how to optionally set an
administrator's password for the switch.
If you define and set a password on a ProCurve switch, you must set the same password on every ProCurve
switch that is a component of your HP XC system.
During the hardware discovery phase of the system configuration processs, you are prompted to supply the
password for the ProCurve switch administrator, and the passwords on every switch must match.
Switch Port Connections
A large-scale system has at least one Super Root Switch. All HP XC systems have at least one Root
Administration Switch and one Root Console Switch. The number of Branch Administration Switches and
Branch Console Switches depends upon the total number of nodes in your system.
The Administration Network using the root and branch switches must be parallel to the Console Network
root and branch switches. In other words, if a particular node uses port N on the Root Administration Switch,
its management console port must be connected to port N on the Root Console Switch. If a particular node
uses port N on the Branch Administration Switch, its management console port must be connected to port N
on the corresponding Branch Console Switch.
A graphical representation of the logical layout of the switches and nodes is shown in Figure 2-2.
