Troubleshooting
the Upgrade
Each access point on a wired LAN requires approximately three minutes
to upgrade (it takes slightly longer for wireless access points). The web
browser screen updates every 30 seconds as the upgrade progresses
and shows the final status when all upgrades are complete. If you
checked Reboot selected Access Points after successful upgrade box,
the web browser disconnects. Select the Refresh button to log in again.
Errors may occur during the upgrade process or during the final reboot.
If an error occurs, an explanation appears on the web browser screen.
If an error occurs during the upgrade, none of the access points reboot.
You should:
1. Recheck the access points where the error occurred.
2. Select Start Upgrade to attempt the upgrade again. If the upgrade is
successful and you checked Reboot selected Access Points after
successful upgrade box, the access points will reboot.
If an error occurs during the final reboot, you should:
1. Wait five minutes for the access points that did not reboot to refresh.
2. Refresh your web browser screen and check the access points that are
not running the new version.
3. Select Start Upgrade to attempt the upgrade again. If the upgrade is
successful and you checked Reboot selected Access Points after
successful upgrade box, the access points will reboot according to
your Reboot selection.
If you need to downgrade an access point to an earlier release, contact
Allied Telesyn Technical Support.
