Verify that:
1. Each port is assigned a unique address by the Configuration/Setup Utility
program and none of the serial ports are disabled.
Note: The management C connector is the same as a serial port connector, but
it is used only by the integrated Netfinity Advanced System
Management Processor, and is not available for use by the operating
system. This port does not appear in the Configuration/Setup Utility
program menus; it can be configured using Netfinity Manager.
2. The serial-port adapter, if you installed one, is seated properly.
If the problem still exists, call for service.
Verify that:
1. The device is compatible with the server.

To determine if problems are caused by the software, verify that:
1. Your server has the minimum memory requirements needed to use the software.
For memory requirements, refer to the information that comes with the software.
Note: If you have just installed an adapter or memory, you might have a
memory address conflict.
2. The software is designed to operate on your server.
3. Other software works on your server.
4. The software that you are using works on another system.
If you received any error messages when using the software program, refer to the
information that comes with the software for a description of the messages and
solutions to the problem.
If the items above are correct and the problem remains, contact your place of
