IBM xSeries 135: User's Reference
If you have a modem, serial printer, or other serial device attached to your server,
verify that the serial cable is connected correctly. If it is, use the following
procedure:
1. Turn off the server.
2. Disconnect the serial cable from the serial port.
3. Wait five seconds; then, turn on the server.
1. Make sure the IRQ and I/O port assignments needed by the serial port are
available.
2. If all interrupts are being used by adapters, you might need to remove an
adapter to make an interrupt available to the serial port, or force other adapters
to share an interrupt.
1. Make sure that the PCI adapter and all other adapters are set correctly in the
Configuration/Setup Utility program. If the interrupt resource settings are not
correct, change the settings.
2. If all interrupts are being used by other adapters, you might need to remove an
adapter to make an interrupt available to the PCI adapter, or force other
adapters to share an interrupt.
Be sure that the drive that you want to start from is in the startup sequence.
1. Select Start Options from the Configuration/Setup Utility program main
menu. See "Using the Configuration/Setup Utility program" on page 12. If you
are unable to set the startup sequence, call for service.
2. Check the list of startup devices in the Startup device data fields. Is the drive
you want to start from in the startup sequence?
Yes Exit from this screen; then, select Exit Setup to exit the
Configuration/Setup menu. Go to step 3..
No Follow the instructions on the screen to add the drive; then, save the
changes and exit from the Configuration/Setup menu. Restart the
server.
3. Is an operating system installed?
Yes Turn off the server. Go to step 4..
No Install the operating system in your server; then, follow your
operating system instructions to shut down and restart the server.
4. During server startup, watch for messages indicating a hardware problem.
