IBM® xSeries 350: User's Reference
Verify that:
1. The printer is turned on and is online.
2. The printer signal cable is connected to the correct serial or parallel 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 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 correctly, 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 is disabled.
Note: The management port C is the same as a serial port connector, but it is
used only by the integrated 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 the systems-management software.
2. The serial-port adapter, if you installed one, is seated properly.
If the problem persists, 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 port C is the same as a serial port connector, but it is
used only by the integrated 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 the systems-management software.
If the problem persists, call for service.
Disconnect the server from all electrical sources, wait for 30 seconds, reconnect the
server to the electrical sources, and restart the server.
If a problem persists, call for service.
