This section is an excerpt from the MobileLAN access WA2X System
Manual (073915-002).
Upgrading the Access Points
For optimal performance, you should install the most current software
version on all the access points in your network. To upgrade the software,
you must copy the software release to your PC and then upload the release
to your root access point and other access points. However, you can also
configure the root access point to copy the release to all other access points
in its spanning tree.
You can upgrade the access point software using:
•Wavelink Avalanche client management system. For help, see “Using
the Wavelink Avalanche Client Management System” in the
MobileLAN access WA2X System Manual and the Wavelink Avalanche
documentation and online help. Or, you can visit the Wavelink web site
at www.wavelink.com.
•the MobileLAN access Utility as a distributed upgrade server. For help,
see the next section, “Using the MobileLAN access Utility,” and the
online help.
•a web browser interface. For help, see “Using a Web Browser Interface”
on page 213.
To copy the upgrade file to your PC
1Using a web browser, navigate to www.intermec.com.
2From the
Service & Support menu, choose Downloads.
3Select the
MobileLAN access product that you are upgrading.
4Click the software link to save the upgrade file on your PC.

Chapter 8 — Managing, Troubleshooting, and Upgrading Access Points
Using the MobileLAN access Utility
The MobileLAN access Utility enables your PC to act as a distributed
upgrade server. The PC stores the upgrade software and you configure the
root access point to retrieve the software at a specified time. You can also
configure the root access point to inform other access points in its
spanning tree where they can get the software so they can be upgraded.
If you use this utility, you only need to configure the root access point and
all access points will be upgraded. However, when the access points request
the upgrade software, the utility must be active.
Note: The PC that is running the MobileLAN access Utility does not need
to be on the same IP subnet as the access points.
For help installing the MobileLAN access utility, see “Using the
MobileLAN access Utility” in the MobileLAN access WA2X System Manual.
To upgrade the access point software
1Start the utility.
2In the Upgrade File Location field, type the path and filename of the
upgrade file (AP*WEB.BIN) or click Browse to find the file. For
example, AP220WEB.BIN.
3Click Start. The utility must remain active until the upgrade procedure
is complete; do not close the utility.
4Configure the root access point to retrieve the software:
aFrom the Actions menu, click Configure Access Point, and then
enter the IP address of the root access point. A web browser session is
established.
bFrom the menu bar, click Distributed Network Upgrade. The
Distributed Network Upgrade screen appears.

cIn the Server IP Address field, enter the IP address of the PC that
contains the software release and that is running the utility.
dIn the Start Time field, choose when you want the upgrade to start.
eCheck the Reboot selected Access Points after successful upgrade
check box if you want the access points to run the upgraded software
after it is downloaded.
If you clear this check box, you will need to reboot the access points
when you want them to run the upgraded software.
5Configure the root access point to tell the other access points where to
get the upgraded software.
aUnder the Access Points on the Network title, you can see a list of all
the access points in the spanning tree.
bCheck the Upgrade check box of all access points you want to
upgrade.
cTo select all the access points that are listed, click the Select All
Access Points button. Or to deselect all the access points that are
selected, click the Deselect All Access Points button.
When the start time expires, the root access point retrieves the upgrade
software and reboots. When it is done rebooting, it will be running the
new software. The other access points that you configured to be upgraded
will also retrieve the upgrade software. If you checked the Reboot selected
Access Points after successful upgrade check box, they will also reboot,
and then they will be running the new software.

Using a Web Browser Interface
You can use a web browser interface to upgrade the access points one at a
time. In other words, for each access point you want to upgrade, you will
need to establish a web browser session with it, upgrade its software, save
the new configuration, and reboot it.
To upgrade the access point software
1Establish a web browser session with the access point you want to
upgrade.
2From the menu bar, click Upgrade Software. The Upgrade Software
screen appears.
3Enter the path and filename of the upgrade file (AP*WEB.BIN) or click
Browse to find the file on your PC. For example, AP220WEB.BIN.
4Click Upgrade to start the upgrade. The upgrade may take up to 3
minutes to complete.
5When the upgrade is complete, click Save Changes and Reboot.
When the access point is done rebooting, it is upgraded to the new
software. Repeat this procedure for each access point you want to upgrade.

Chapter 8 — Managing, Troubleshooting, and Upgrading Access Points
Troubleshooting the Upgrade
Each access point on a wired LAN requires approximately 3 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 the
Reboot selected Access Points after successful upgrade check box, the
web browser disconnects. Click 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:
1Recheck the access points where the error occurred.
2Click Start Upgrade to attempt the upgrade again. If the upgrade is
successful and you checked the Reboot selected Access Points after
successful upgrade check box, the access points will reboot.
If an error occurs during the final reboot, you should:
1Wait 5 minutes for the access points that did not reboot to refresh.
2Refresh your web browser screen and check the access points that are
not running the new version.
3Click Start Upgrade to attempt the upgrade again. If the upgrade is
successful and you checked the Reboot selected Access Points after
successful upgrade check box, the access points will reboot according
to your Reboot selection.
If you need to downgrade an access point to an earlier release, contact
Intermec Technical Support.
