Program
The controller can be configured and monitored remotely through a
modem. If there are several RAID systems in several different places,
the administrator can remotely administer all the controllers on his
desk by using a terminal emulation program.
There is no need to install a RAS (Remote Access Server) to AA-
3102RS. Simply connect a modem to AA-3102RS. AA-3102RS can
manage by itself the dial-in remote administration and dial-out event
notifications through the proper settings.
If the controller is not connected as a redundant controller, COM 1 can
be used as the local RS-232C terminal interface, Acer RAID Manager
connection or PPP connection to the host computer. COM 2 can be
used to provide a remote administration service by connecting a
Modem. The terminal emulation screen will show that COM 1 and
COM 2 are exactly the same and synchronized. It is a must to retain
the Initial screen when not using it. The password will be asked for
verification only when entering the Main Menu from the Initial screen.
