Getting Started Guide for Wireless EDGE Services xl Modules 2007-07

Introduction
■ System-wide access control and security policies across wired and wire-
less infrastructure, providing easier network security management when
ProCurve Identity Driven Manager is used.
Radio Port Licensing
A wireless services-enabled switch has a maximum number of radio ports that
it may adopt, based on the licenses installed.
■ Only a Module (J9001A) has licenses.
■ When a Module moves from one slot to another, or from one 5300xl switch
to another, its licenses remain the same.
■ A non-removable, 12 radio port license is installed at the factory. The
purchase and installation of a ProCurve Wireless Services Module 12 RP
License (J9002A) increases the number of radio port licenses in a Module
by 12. The total number of radio port licenses can be either 12, 24, or 36.
■ Licenses can be uninstalled and reinstalled in another Module in groups
of 12 radio ports.
■ A Redundant Wireless Services xl Module is not licensed and cannot
independently adopt radio ports. However, these modules can adopt radio
ports as part of a Redundancy Group (see the next section).
Redundancy
Two wireless services-enabled switches can cooperate to reduce the chance
of disruption in the wireless service in the event of a wireless services-enabled
switch or an intervening network failure. Typically, a Module and a Redundant
Wireless Services xl Module are configured as members of a Redundancy
Group. In the event of a failure, radio ports previously adopted by the failed
wireless services-enabled switch automatically migrate to another member of
the Redundancy Group.
■ A Module by default does not participate in any Redundancy Group and
is standalone. For a set of Wireless Edge Services xl Modules to become
a Redundancy Group, the administrator must configure each of them to
know about the other. Multiple groups may be formed and operated
independently. Each group is identified by a unique Group ID.
■ A Redundancy Group is normally formed with one Module (J9001A) and
one Redundant Wireless Services xl Module (J9003A). Two Wireless Edge
Services xl Modules may be members of a Redundancy Group, but the
highest authorization level of a single member becomes the authorization
level for the group. Authorization levels of the members are not added to
form the group’s authorization level.
