Appendix A – Device Manager Utility
MultiAccess Firmware Update
1. In the Device column of the Device Manager screen, identify the MultiAccess unit on which the
update is to be done. Be sure that the Status of that MultiAccess unit is idle before continuing.
(You cannot update the MultiAccess while it is handling a call.) Select that MultiAccess unit and
right-click on it. In the menu that appears, select Update.
2. The Update MultiAccess ACS at N.N.N.N screen will appear. The current firmware versions for
the MultiAccess firmware and for POTS Modems will be listed in the main window.
In the bottom (and largest) pane of the Update MultiAccess ACS at N.N.N.N window, read the
list and write down the version of firmware currently in use for the MultiAccess. 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.
3. In the MultiAccess ACS Update Select field, select "MultiAccess ACS firmware."
