The following illustration shows a modem connected to the serial port of the
Remote Supervisor Adapter in the xSeries 440 on the left, a modem connected to
the serial port of the Remote Supervisor Adapter in the xSeries 440 on the right,
and a modem connected to the remote administrator system. Placing modems at
opposite ends of the ASM interconnect network bus ensures that if an ASM
interconnect connection in the bus fails, all of the servers on the ASM interconnect
network have access to a modem to forward system-management data to the
remote system-management administrator.
