Verify that:
1. The power cables are properly connected to the server.
2. The electrical outlet functions properly.
3. The type of memory installed is correct.
4. If you just installed an option, remove it, and restart the server. If the server now
powers on, you might have installed more options than the power supply supports.
5. The LEDs on the power supply are on.
If the problem remains, call for service.
Verify that:
1. The printer is turned on and is online.
2. The printer signal cable is connected to the correct port on the server.
Note: Non-IBM printer cables might cause unpredictable problems.
3. You have assigned the printer port correctly in your operating system or application
program.
4. You have assigned the printer port correctly using the Configuration/Setup Utility
program.
If the items above are correct and the printer still does not work, run the tests described
in the documentation that comes with your printer. If the tests show that the printer is
working properly, call for service.
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 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.
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.
2. The serial port is enabled and is assigned a unique address.
3. Make sure that the device is not connected to the management port C.
Note: The management C connector is the same as a serial port connector, but it
is used only by the Integrated 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.
If the problem still exists, call for service.
