6. After code has been downloaded for the first time, the Wireless IP Telephone will ask
for an extension and password. Once these have been entered, the phone will register
with the Avaya Aura™ Communication Manager.
For future software upgrades, simply update the files that are stored on the TFTP

Server. Each time the Wireless IP Telephone is powered up, it will check with the
TFTP Server to ensure it has the proper software version. If a new version of code
is downloaded, the currently-entered extension and password will be preserved.
Rules and recommendations for software downgrades:
•
When downgrading to a former release using TFTP, use the slnk_cfg.cfg file provided
with the older release.
•
When upgrading and downgrading with HAT, we recommend updating all of the files,
even if the version looks correct as data within a file can change while retaining the
same filename.
• If you perform repeated downgrades and upgrades you may notice that the TFTP
server does not always send all five files. This is correct. For example, the
pd14shim.bin does not need to be deleted during downgrade to an older version.
•
After a downgrade is completed, we recommend resetting the handset to factory
defaults.
