Troubleshooting Option Problems An IBM option that was just installed does not work. Action Verify that: 1. The option is designed for the system. 2. You followed the installation instructions that come with the option and the instructions in Chapter 4, "Installing Options" on page 51. 3. You have not loosened any other installed options or cables. 4. If the option is an adapter, you have provided enough hardware resources for the adapter to function correctly. Refer to the documentation that comes with these adapter (as well as the documentation for any other installed adapters) to determine the resources required for each adapter. 5. All option files (if required) are installed correctly. See "Installing Files from Option Diskettes" on page 123 for information on installing option files. 6. You updated the configuration information in the Configuration/Setup Utility program, if necessary, and have no conflicts. Whenever memory or an option is changed, you must update the configuration. For information on using the Configuration/Setup Utility program, see "Using the Configuration/Setup Utility Program" on page 28. If the problem persists, run the diagnostic programs. (See "Running the Diagnostic Test Programs" on page 124 for additional information on running the diagnostic programs that come with your server.) If the problem cannot be isolated and corrected, have the server and the option serviced. Parallel Port Problems The parallel port cannot be accessed, or the number of parallel ports displayed is less than the number of parallel ports installed. Action Verify that: 1. Each port is assigned a unique address. To verify the address, run the Configuration/Setup Utility program, and select Devices and I/O Ports. See "Devices and I/O Ports" on page 30 for additional information. 2. The parallel-port adapter, if you installed one, is properly installed and firmly seated. For information on installing adapters, see "Installing or Removing Adapters" on page 61. If the items above are correct, have the system serviced. 168 Netfinity 3500 User's Handbook
