If the wrong language is displayed, update the BIOS code with the correct language.
If the problem remains, call for service.
Verify that:
1. The option is designed for the server. Refer to the "Server Support" flowchart for
information about obtaining ServerProven™ compatibility information from the World
Wide Web.
2. You followed the installation instructions that came with the option.
3. The option is installed correctly.
4. You have not loosened any other installed options or cables.
5. You updated the configuration information in the Configuration/Setup Utility program.
Whenever memory or an option is changed, you must update the configuration.
If the problem remains, call for service.
Verify that all of the option hardware and cable connections are secure.
If the option comes with its own test instructions, use those instructions to test the option.
If the failing option is a SCSI option, verify that:
1. The cables for all external SCSI options are connected correctly.
2. The last option in each SCSI chain, or the end of the SCSI cable, is terminated
correctly.
3. Any external SCSI option is turned on. You must turn on an external SCSI option
before turning on the server.
If the problem remains, call for service.
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. 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; it can be configured using
xSeries Manager.
2. The serial-port adapter, if you installed one, is seated properly.
If the problem still exists, call for service.
