This error refers to the current license on the unit. You can update the firmware on the LoadMaster if the unit is in support.
You can view license and support information on the LoadMaster Web User Interface (WUI) home screen by clicking View License.
Note that Licensed Until refers to how long this unit will be activated for. For example, if this is a trial unit, it will be activated for 30 days. If this is a permanent unit, it will be activated indefinitely. This is separate from the field Support Until. The unit must be in support to apply firmware updates.
If support has been renewed recently, the unit may have the old support date. In this scenario, you must update the license on the unit using the online or offline licensing method. For steps on how to do this, refer to the Licensing Feature Description. After licensing, you should be allowed to update the firmware.
