MultiAccess ACS Firmware Update
1. In the Device column of the Device Manager screen, identify the MultiAccess ACS unit on which
the update is to be done. Be sure that the Status of that MultiAccess ACS unit is idle before
continuing. (You cannot update the MultiAccess ACS while it is handling a call.) Select that
MultiAccess ACS unit and right-click on it. In the menu that appears, select Update.
2. The Update MultiAccess ACS N.N.N.N screen will appear. The current firmware versions for
the MultiAccess ACS firmware and for POTS Modem 1 will be listed in the main window.
In the bottom (and largest) pane of the Update MultiAccess ACS N.N.N.N window, read the list
and write down the version of firmware currently in use for the MultiAccess ACS. Compare the
version with the update file that you plan to use. Make sure that the file to be installed really does
supersede the one currently installed on the MultiAccess ACS.
3. In the MultiAccess ACS Update Select field, select “MultiAccess ACS firmware.”
