The following illustration shows a modem connected to the serial port of the Remote Supervisor Adapter in the xSeries 450 on the left, a modem connected to the serial port of the Remote Supervisor Adapter in the xSeries 450 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.
