Connecting a Managed System with a 9-Pin Serial Port

Systems with 9-pin console ports are usually supplied with a 9- to 25-pin cable used to connect to the console. The console is usually a DTE device. For this reason, Unisys uses the existing cable to ensure the correct DCE/DTE pairing.

To make the connections, perform the following steps:

  1. Connect the system’s supplied 9- to 25-pin console cable to the modem adaptor.

  2. Connect the modem adapter to the serial port on your Operations Sentinel server with the appropriate straight-through cable.

Figure H-7 shows how to connect a managed system with a 9- to 25-pin cable to an Operations Sentinel server serial port.
