UPGRADE NOTES
Important: Please read the ProCurve Secure Access 700wl Series Software Version
4.5.0.37 Update Guide for instructions on updating your systems that currently run
software version 4.1.3.93. The Update Guide applies equally to this patch release.
The update process is a two-step process, requiring an intermediate update to software version
4.1.4.6 before updating to 4.5.0.37. If you do not update through the intermediate version, you
will not be able to downgrade back to the 4.1.3.93 software should the need arise.
If you are running a 4.4 version, you can perform an upgrade directly to 4.5.0.37.
The ProCurve Secure Access 700wl Series Software Version 4.5.0.37 Update Guide may be
downloaded in PDF format from the HP ProCurve Technical Support web site at

Important: Back up your systems before upgrading to the version 4.5 software!
CLARIFICATIONS AND USAGE NOTES
• Cross-VLAN functionality has changed in the ProCurve Software Release 4.5. For client
cross-VLAN communications, traffic from clients on different VLANs is no longer directly
switched between VLANs within the ProCurve module. Instead, all cross-VLAN traffic is
forwarded to the Uplink networks for traffic forwarding. Properly configured networks on
the Uplink should be designed to handle this function, as this is the only way to ensure that all
cross-VLAN traffic is verified as part of the organization’s access policies.
• The Integrated Access Manager 760wl no longer supports remote Access Controllers, the
ProCurve Access Controller 720wl (J8153A) or the ProCurve Switch xl Access Controller
Module (J8162A) A 760wl can only be used as a stand-alone unit.
• Release 4.1 is not compatible with release 4.4 or higher. For example, release 4.1 on an
Access Controller will not work with release 4.4 on an Access Control Server, and release 4.4
or higher on an Access Controller will not work with release 4.1 on an Access Control
Server.
• After migrating to version 4.5.0.37, a downgrade can only be made to version 4.1.4.6. If the
alternate version is lower, 4.1.4.6 must be obtained to ensure a proper downgrade. For more
information, see “Downgrading to the Previous Release” in the ProCurve Secure Access
700wl Series Software Version 4.5.0.370 Update Guide.
• Network and subnet configuration data is split between local network information and global
network information. Configuration data that is likely to be shared between different Access
Controllers is stored in global subnet groups. This includes information like DNS, WINS and
domain names. These fields are entered manually or can be automatically set from
information in a DHCP lease.
