Software Update Guide for 4.1.3.93 to 4.4.0.50

Updating the 700wl Series
The enhanced support for 802.1Q VLANs is discussed in this document, as
customers using port subnetting will need to reconfigure their system to use
VLANs and subnets under the new software.
Caution Because of the significant changes in the way subnets and VLANs are handled
in release 4.4.0.50, it is not backward compatible with software version
4.1.3.93. However, to support a downgrade from 4.4.0.50 to 4.1.3.93, an inter-
mediate release, version 4.1.4.4, must be used. The update process requires
upgrading first from 4.1.3.93 to 4.1.4.4, and then from 4.1.4.4 to 4.4.0.50.
Updating the 700wl Series
To update from version 4.1.3.93 to 4.4.0.50, the following steps are required.
1. If you have port subnets configured as part of the port configuration on
your Access Controllers, and if you have VLAN tags associated with those
subnets, make sure you record the relevant information. You will need to
recreate these subnets as uplink VLANs under software version 4.4.0.50.
Port subnet configurations can be viewed by selecting the Network icon
on the Navigation Toolbar, then the Access Controller you want to view.
Select the Interfaces tab, then the Subnet sub-tab to see the port subnet
configurations for the Access Controller.
This tab does not exist in the 4.4.0.50 software version, and these settings
will be lost upon the update to 4.4.0.50.
2. Back up your Access Control Server 740wl.
The backup can be performed from the Backup & Restore tab under the
Maintenance function (the Maint icon on the Navigation Toolbar). See
information in the ProCurve Secure Access 700wl Series Management
and Configuration Guide, Chapter 8, for more detailed instructions.
This step is critical if at a future time you need to downgrade the system
to 4.1.3.93.
3. From the Access Control Server, update each connected Access Control-
ler or Access Controller xl Module, updating each one first to 4.1.4.4,
rebooting, then updating to 4.4.0.50.
