Chapter 1 Maintaining Your WAAS System
Upgrading the WAAS Software
The Device Dashboard window appears.
Step 2 Verify that the device is not already running the version to which you plan to upgrade.
Step 3 Click the Update link.
The Software Update window appears.
Step 4 Choose the software file URL from the Software Files list by clicking the radio button next to the
filename.
The list displays only software files with an image type of Universal, because you are upgrading a
Central Manager device. If no such images are available, you must create a software file as described in
the “Specifying the Location of the Software File in the WAAS Central Manager GUI” section on
page 1-3.
Step 5 Click Submit, and then click OK to confirm your decision.
The Devices listing window reappears. You can monitor the progress of your upgrade from this window.
Software upgrade status messages are displayed in the Software Version column. These intermediate
messages are also written to the system log on the WAAS devices. See Table 1-2 for a description of
upgrade status messages.
Step 6 Clear your browser cache, close the browser, and restart the browser session to the WAAS Central
Manager.
The WAAS Central Manager may reboot at the conclusion of the upgrade procedure (if Auto Reload was
checked in the Creating New Software File window), causing you to temporarily lose contact with the
device and the graphical user interface.
