9.6.5 Firmware
Device Management: Firmware tab
Note: The first time you access the Firmware tab after opening your web browser, you are asked
to authenticate. Next, a security alert displays. Using the A-80 firmware upgrade feature
requires Java Runtime Environment 1.6 or higher. The Siqura application does not give rise to
any security risks. You can run it safely.
Firmware images
The A-80 has two firmware storage areas: a fixed image area and an upgrade image area. The
fixed image area contains the original factory version of the firmware. This cannot be erased. The
upgrade image area is usually empty upon factory release.
If the existing firmware in the A-80 is to be replaced, a new version can be written to the upgrade
image area. There, the new image resides in erasable (flash) memory.
An upgrade image can replace an existing upgrade image written to the device at an earlier
upgrade. It is essential that the upgrade image is compatible with the A-80.
Important: If an error should occur during the upgrade procedure, the A-80 will not revert to a
former upgrade image. Instead, it will be downgraded to the fixed image.
