MSM3xx, MSM4xx, HP 425, and HP 517 APs Release Notes v6.4.0.0

Mandatory channel change required prior to software upgrade; discontinue
use of channel 132
Applies to these Americas/USA models: MSM410 (J9426A/B), MSM422 (J9358A/B), MSM430
(J9650A), MSM460 (J9590A), MSM466 (J9621A), MSM466-R (J9715A), MSM310 (J9374A/B),
MSM310-R (J9380A/B), MSM320 (J9360A/B), MSM320-R (J9365A/B), MSM325 (J9369A/B).
IMPORTANT: Prior to upgrading to MSM software version 6.4.0.0, all applicable APs (autonomous
or controlled) that are manually configured to use channel 132 must be either reconfigured to use a
different channel or be reconfigured to use auto channel. This is required because channel 132 is no
longer available for use.
NOTE: Due to a problem with AP channel use validation, a banner similar to this may appear at
the top of the Home screen: AP CNxxxxxxxx, Radio 1 channel configuration has been
set to autochannel because the previously configured channel is not
supported by this version of software. The same message is added to the system log.
These messages can be safely ignored.
Updating software
(Not applicable to HP 425 and MSM317.) For autonomous APs, update the software as described
in the “Software updates” section of the MSM3xx / MSM4xx APs Configuration Guide.
For controlled APs including the HP 425 and MSM317, update the controller software as described
in the “Software updates” section of the MSM7xx Controllers Configuration Guide. After the controller
update is complete, it automatically updates all of its controlled devices to the same software version.
Downgrading software
If you upgrade to version 6.4.0.0 and then wish to return to the version that you had been running
prior to upgrading, the configuration that you used originally with that version will still be available.
If you have made configuration changes while using version 6.4.0.0, those changes will not be present
when you downgrade to the previous version.
If you factory reset your device after upgrading to version 6.4.0.0, your previous configurations will
be lost, and when you downgrade to any previous version you will be in a factory reset state.
MSM management tool requires web browser with SSLv3 support
NOTE: A web browser that supports SSLv3 is mandatory for running the MSM web-based management
tool. SSLv3 is supported by Microsoft Internet Explorer 7 and 8 but must be enabled. Microsoft Internet
Explorer 9 and later uses SSLv3 only. Mozilla Firefox also supports SSLv3 but support may need to
be enabled or you may need to update to a more recent version.
