System Configuration

Upgrading from v1.0.X.X to 1.1.X.X/1.1.1.x is a two step process requiring the same upgrade
procedure to be repeated twice. The first upgrade will result in a bootloader change, and the second
upgrade will result in a firmware change. For subsequent upgrades, a single download will suffice.
Using Auto Update, the access point will automatically update itself twice when upgrading.
Upgrading from v1.0 to v1.1/v1.1.1 retains existing settings. Symbol recommends that users export
their 1.0 configuration for backup purposes prior to upgrading.
When downloading from v1.1.1/v1.1 to v1.0, all configuration settings are lost and the access point
returns to factory default settings.
For detailed update scenarios involving both a Windows DHCP and a Linux BootP server
configuration, see
Configuring Automatic Updates using a DHCP or Linux BootP Server on page B-1
.
If a firmware update is required, use the
Firmware Update
screen to specify a filename and define
a file location for updating the firmware.
CAUTION
If downgrading firmware from a 1.1 to a 1.0 version, the access point
automatically reverts to 1.0 default settings, regardless of whether
you are downloading the firmware manually or using the automatic
download feature. The automatic feature allows the user to download
the configuration file at the same time, but since the firmware reverts
to 1.0 default settings, the configuration file is ignored.
NOTE
An AP-5181 does not support any firmware versions prior to 1.1.1.0.
.
CAUTION
Loaded and signed CA certificates will be lost when changing the
access point’s firmware version using either the GUI or CLI. After a
certificate has been successfully loaded, export it to a secure location
to ensure its availability after a firmware update.
NOTE
The firmware file must be available from an FTP or TFTP site to perform
the update.
CAUTION
Make sure a copy of the access point’s configuration is exported
before updating the firmware.
