IMPORTANT:
Switch use is not strictly enforced on HP XC systems with HP server blades.
For more information about switch use with HP server blades, see
lists the switch models that are supported for each use.

3.3.2 Administrator Passwords on ProCurve Switches
The documentation that came with the 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 the HP XC system.

During the hardware discovery phase of the system configuration process, you are prompted to
supply the password for the ProCurve switch administrator, and the password on every switch
must match.

3.3.3 Switch Port Connections
Most 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 the hardware configuration.
The number of Branch Administration Switches and Branch Console Switches depends upon
the total number of nodes in the hardware configuration.
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.
