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.
