AP-51xx Access Point Product Reference Guide

• Export either a CA or Self Certificate to a safe and secure location before upgrading or 
downgrading your access point firmware. If the certificate is not saved, it will be discarded 
and not available to the user after the upgrade or downgrade. If discarded, a new certificate 
request would be required.
• Upgrading from v1.0.x.x to 1.1.x.x/1.1.1 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. 
Motorola 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.
NOTE For a discussion on the implications of replacing an existing AP-4131 
deployment with an AP-5131 or AP-5181, see Replacing an AP-4131 with 
an AP-5131 or AP-5181 on page B-20.
